I'm not sure if this has ever been implemented yet, but can you imagine a way of paying with Bitcoin by just using your own body?

It would be more of like a microchip implanted into your left or right hand that would contain both your public and private keys to send and receive Bitcoins.

So in case you want to send or receive some BTC, you would just pass your hand over at a scanner and it would perform the desired operation. This is would make it a very convenient and easy way to transact, and carry your Bitcoins with you anytime, anywhere. However, the only thing to be considered would be the security of your private key from within your implant, to protect your funds from theft.

Nevertheless, I want to know your opinion about this, since it would be pretty cool to have such a system to help spread mass adoption of the cryptocurrency.  :)

As long as is not bad for the health, and is just a microchip that you can carry in your belt this would be an awesome idea.

Been there, done that.

http://motherboard.vice.com/read/this-guy-implanted-his-bitcoin-wallet-and-made-a-payment-with-his-hand

Besides the obvious problem with security this sounds like a lot of science fiction, but i see no technological problems. So this could be available even today. The question is why would you want that? How can you make money if you offer such services? I just see no need and many risks.

Yeah, I remember reading about that article about some guy that already did the first payment with his hand or something like that, throught a chip that read a QR code or something. The thing is, it's pretty stupid thing to do in my book. In the future once bitcoin is 1 mansion per coin, you are asking for some robber to your hand and use it to go shopping..

before anyone does it.. may i suggest that people first buy a NFC sticker that they attach to a wrist watch/band first.
much like getting a fake tattoo before going under the needle and trying it for real

i know a few people use it as a way to unlock a phone. and do other snazzy things and others are envisioning a way to access other things. but here is a security thing to think about:

if you want to use implants/nfc to do things.. have the code/message changeable, not permenant. EG when you wake up you scan your wrist to update the code/message in the chip from the safety of your home. and that sets it to be valid for that day. and have it change each morning.

the reason is because people can easily walk/brush passed you in public and read the data and simply emulate it. so having the data permanent is BADDD.

what people have done is use a known keypair where the service knows only the public key. the chip stores just a daily "signed message"
EG
"its 20/12/2016 i own 1abcdefg..."

which is verifiable to the public key without revealing the private key. because the privkey is not part of/stored on the chip

nfc chips are not sophisticated enough to receive data and then instant sign it, (hence manually daily updating required).

but it does open up opportunities..
years ago i did suggest blockchain.info had their login method set as a public key where blockchain.info displayed a daily message and people would need to reply/paste/input a signed message to confirm they own the registered publickey.
(research BitID)

I don't think the whole idea about chips under your skin is a good thing.. I mean c'mon you could use a Trezor or even invent a better hardware wallet for all people care, but you know if we start messing with our bodies I think we'll see some terrible mistakes at the near future (transhumanism).

No, it wouldn't. Sounds a lot like Revelation, referring to the Anti-Christ's mark.

"And he causes all, both small and great, rich and poor, free and bond, to receive a mark in their right hand, or in their foreheads: and that no man might buy or sell, save he that had the mark, or the name of the beast, or the number of his name"

“If any man worship the beast and his image, and receive his mark…the same shall drink of the wine of the wrath of God…”

I'm not sure what to think about it. This idea that I carry some chip in my body reminds me on some kind of surveillance and some science fiction movies. Probably it would be very practical and secure but it doesn't sound attractive to me at all. On.the other hand there are no guarantee that this chip couldn't be used for some wrong purpose. I'm not against inovations, on the contrary, but I wouldn't do this.

This idea is fitted at malls, replacing the cards, having a microchip in your hand will be convinient cause you don't have to carry your cards. The main problem here is not about your private key but the fact that why would someone have to implant a chip in his hand for that purpose, Carrying a card or two is not really a problem. The project is nice but I don't see any advantages of this that is worth it enough for people to have their hand implanted with a chip. Problem number two is its health risks. If there is, then it will not be worth

Thanks. I've been waiting for some christian fear monger to post that.

interesting, i didn't know that exist already, it would be cool if it was possible to scan the eye to do a transaction, but i guess it would be more dangerous, also if a guy like him will carry his phone anyway, i see that it's better to just use that to pay

The idea is good, but I would not like to have an implant in my body to be able to receive and send my bitcoins. This implant should cause health issue, or in the case that you take the airplane, do you need to change the mode ;)

So the next generation of wallet will be a human wallet in the future!

Such advancements were not needed. Because one in ten uses such methods for easy accessing. This looks like a step ahead than the ongoing development. The coming generation might give preference to these kind of fantasy based usage of bitcoin and other digital currency with the hand acting as a wallet for all needs.

imagine it. having to have an implant to get a job.. then sacked 3 months later because its a mundane stupid 'mall cop' job. now you have to have surgury to get the chip out.

yea easy to inject in. but getting out.. um not so easy and no employer would pay a sacked employee for hospital treatment, so not really a positive thing in places like malls that see a high turnover rate of staff.

but for anyone thinking of the oppertunities/possibilities.. stick with nfc stickers that attach above the skin or on things.. not under the skin

You're thinking is on the right path. We're not far away from that kind of system anyway. We know paper money is not long for this world. There are a couple of obscure companies researching biometric scans (such as fingerprints and retinal scans) as a method of debit card replacement but there are flaws in implementation left to overcome. The expense of the very sophisticated equipment is a big one. It's likely the only countries that could easily implement something like that are small ones with a strong technological infrastructure. They've even looked at the possibility of a blood pressure and pulse detection system to determine if the body part being used for payment is on a living person and that person is not under duress (to eliminate theft).

Here's another: https://www.cryptocoinsnews.com/first-bionic-bitcoin-cyborg/

NFC/RFID use residual energy to send out a predefined message.

if someone can work out the actual microvolts needed to receive message(a), sign it and send message(b) and develop a small/safe nfc/rfid that can do some basic 'processing' such as signing a message using edcsa keypair or bitcoin keypair. then they can be in for alot of potential as a possible new industry

until then ... manually updating the stored 'message' daily/weekly/random time is the only solution. though better than biometric data (isues with papercuts/dirt ruin fingerprints, cateracts retinal scarring(diabetes) ruin retina scans), its still better to have a identifier that can change per day/use.

No problem.  We'll only install it in the left hand.  Then we can avoid an early second coming and we can all do business without fearing "the wine of the wrath of God".

Simple solution.

When you resort to name calling or insults instead of discourse, you lose my respect.


Haha love ya man, sounds great to me  ;)

Thats good idea but too hard to implement and there's so many risks with that, first your health if this chip can be good to person's body, and to become safe, once bad people knows that you handle/own lots bitcoin in your body/hand well you're in danger and be chased with this bad guys.

I can imagine payment for staff and other things by using only our bodies. The topic of such kind of chips showed in fantastic movies from several years ago. And I think this fantastic will come true one day. I don't even wish to think what danger it may follow, bit it's humans nature to afraid of something new.

I would never want something like that... Somebody would have control over everything about you. Microchips are usually able to take a lot of information, like the food intake or so. Implanting such things means control. There chips are connected to GPS.. What happens if it brakes, or what happens if it needs a repair? There are many things because of which I do not want to accept this idea.

Guys, do yourselves a favor and come to the next Hackers Congress (HCPP17) in Paralelni Polis. This is not an advertisement, it is just a good advice on how to broaden your horizons in terms of what is possible with Bitcoin. E.g., we accept only bitcoin, no fiat. There are already 30 people who come to us regularly and do payments with an NFC implant. You will be able to meet some of them at the congress and talk to them personally. I myself use it on a daily basis.

Here is my video demonstrating the payments - https://www.youtube.com/watch?v=pdauofdGFBM

This thread is full of misconceptions and it would take too long to explain in detail. I will try to keep it short and you can come meet me in person to get more details.

- the health risks are very low, especially once it heals
- the security is ok for pocket money
- signing transactions inside the chip would protect you from someone stealing your private key, but you still have to trust the POS
- you can change the private key as often as you want, you also do not have to keep more btc on it than for a few coffees
- no, the god will not be angry, there is no beast, devil, or whatever, you will not go to hell for having a "glass splinter" under your skin
- surveillance with an NFC chip is a stupid idea, you have your phone for that
- in case it is not clear: there is no GPS in the chip, not even a battery
- the implant can not control you, detect what you eat, etc. -- it does not interact with your body
- you can go on airplane with the implant, the airport security check does not even detect it
- removing the implant is even easier than getting it in
- taxation is theft

That's exactly what it reminds me of, too, and it's scary where the world is headed with technology.  The future is upon us, man.  We could be using each DNA sequence on each arm of a chromosome as a private key or some other thing.  Pharmacogenetics is becoming real.  Our consciousness is going to be uploaded to a cloud someday, and that's going to give us all immortality.  And hey, bitcoin is at $800.  Wooo hooo!!

Oh please don't say that. I've been waiting all my life to build up respect with you. Damn, now I've blown it. LOL

I dont want and I dont agree using bitcoin digital devices to use bitcoin. First since it sounds like a demonic plan to control humanity in the end of times and many will protest against especially Christians. Second, if the government will allow it the criminals and the robbers will simply cut off your arms so they can access your bitcoins, I dont want to lose my arms that way. So i prefer bitcoin using app devices such as cp which we can install security features even if snatched they cannot easily access your bitcoins and also there will be no protest from the masses.

You are right it is very risky when it comes to health and also in danger if someone will know that you do have a chip that you are holding a big amount of bitcoin thats it is risky. When it comes to healt it very risky also because we dont know if your body will accept the chip or not if your body will not accept it then it is very dangerous

Lol. I think that idea is from the movie i watched before. If im not mistaken. Its from Justin Timberlake movie. I just dont know what the title of that movie. The difference of this idea is its time not bitcoin. Does anyone here watched this movie?
Thats a good idea tho. It will be a lot easier to transfer funds. But not wise enough. What if the person you are going to tranfer funds has a infectious desease?

No. Time is their life. You should watch that movie . its really a good movie to watch. http://m.imdb.com/title/tt1637688/
Theres no aging. Only time is their life. They were also able to transfer that time to extends ones life.
The title of that movie is "In time". Starring Justin Timberlake and Amanda Seyfried.

This seems like an interesting idea and this is actually possible to do with our current technology but won't be happening anytime soon I guess since there are a lot of problems associated with it.

Brainwallet is something similar but it does not actually "implants" into human body. Instead, we memorize the passphrase in our brain and then use it.

The idea of Bitcoin implants is actually good and I see a bright future with it as technology continue to grows to provide more innovation and security.


Interesting article. Thanks for sharing the article. When I first read the topic, I thought to myself that this can happen but not with today's technology.


If one Bitcoin is equal to 1 mansion worth. Then ... who would store 1 mansion worth of Bitcoin in their bio-wallet. I don't think any average person will store 1 mansion worth of Bitcoin inside a wallet that is located within the same system - be it software, hardware, offline or even paper wallet.

While reading the OP, I remember the movie  "In time" starring Justin Timberlake, where everything around them is run by that time that are in their wrist, every transaction they have have to be paid with time that are saved in them, the more you have it, the more you are going to live like an immortal.... BTT, I think it's a good idea, like having a metal bracelet and your bitcoin wallet is in there, or it is tattooed in your hands...  :)

And the criminals will cut your hand to steal the microchip. ;D Just kidding.

This idea is too futuristic and it`s pointless to implement this nowadays.

Why do you need to put a stupid chip into your arm to do that, if you can simply insert it into a piece of jewelry or better yet, just use tap-and-go credit cards. The people doing this, just wants to be controversial and are desperate for attention. It reminds me about the story of the NASA spending millions on developing a pen that would write in zero-gravity. The Russians spent nothing on this, and simply used a pencil.  ;D ;D ;D ;D ;D

Do not try to re-invent the wheel, we use 100's of other methods and it is just as convenient and safe as a chip in the arm. < overkill >

 

This would scare the fart out off some religious nuts. You know, the Mark of the Beast and stuff...

Anyway, having your btc in a chip implanted into your hand would not guarantee that it won't get stolen. They for example, can just tear it of your flesh, etc.

No, at least for me... The price needed for the surgery for the implant is high, and if the bitcoin wallet is implanted and someone have hacked your wallet by some ways then your wallet will become useless and you'll have to change your wallet (with lots of pain) or keep that useless wallet in your hand...

Also if one day no one use Bitcoin and they become worthless (other than being a part of the Internet history), the wallet in your hand will also become useless and you'll have to carry that piece of circuit in your hand for life...

I'll not implant any other thing (including tattoos) into/onto any part of my body unless it is a life-saving medical machine. But this will not happen for me in the near future - I'm still young and being healthy now.

I don't but this kind of technology might give criminals an idea. Making your body a wallet for Bitcoin can be dangerous. Because bad people will just cut/severe your body part in order to obtain all your Bitcoins. Also not only that they can also kidnap you and do the same result, stealing all your Bitcoin. I am contented with what is holding my Bitcoin now.

Most of the invention in technology are made to improve life but most times come with another problem. The bitcoin NFC(Near field communication) implant is not new( more than 2years) but just an upgrade to the previous implants. The implant function also with credit cards information, key card data,bitcoin keys etc. It was demonstrated early in the year by a prof in Ukraine, it was describe to be absurd, like 'do we really need it?'. Body filled gadget are not as convenient to some people's mind. The chip might be cheap but expensive to implant. In the foreseeable future there might be health implications. Technology is improving at the good and bad side of life. If the bad side of technology gets better than the good, there will be a loss, which make it vulnerable to be hacked.

I'm such a Luddite - I think it is foolish to carry contactless cards, let alone use them. I sent all mine back and use standard cards.

 Why risk somebody stealing your Bitcoin when you shake hands with a thief if you used this implant idea?

I have always found this technology so interesting and also at the same time a little bit frightening to be honest. you are inserting a microchip inside your body, well granted it is only under your skin but still I feel so uncomfortable only thinking about it.

but I guess it is the future, and I would certainly love to see bitcoin become that popular that it starts in these new areas of technology too.

You did pick up, that I used the word, "story" Right? The real facts are even more redicilous, " Originally, NASA astronauts, like the Soviet cosmonauts, used pencils, according to NASA historians. In fact, NASA ordered 34 mechanical pencils from Houston's Tycam Engineering Manufacturing, Inc., in 1965. They paid $4,382.50 or $128.89 per pencil. When these prices became public, there was an outcry and NASA scrambled to find something cheaper for the astronauts to use."

The point I am trying to make, still stands : Implanting a foreign substance into your body to pay for goods and services are just stupid, and a over engineered idea that are easily solved by
much less radical payment options. I still think these people are just doing it, because it is regarded by many as a Taboo. < Religious or Social >  

Exactly. The convenience of not having to carry credit cards, or even cash, makes it a great way to help spread the adoption of cryptocurrencies via implants, since they can fit in almost any place no matter how small, in contrast to cash or credit cards. Plus, you can program it with even more features not only for money, but for storage of personal data too that would prove to become useful for healthcare, and more.

However, if security is not taken into consideration, then it would be useless (not to mention the health risks, which is the most important thing to consider.) Nevertheless, can you imagine of a global government that would require each of its citizens to use the implant? It may not use Bitcoin, by their own digital currency instead (like perhaps fiat USD or EUR). Just sharing my thoughts.  ;D

I kind of like the idea. Think of how easy it would be going to a pool bar and not having to take your wallet with you or walking to the beach and not having to worry about your wallet on the beach while you play in the water. I lost a wallet at the beach once. I used to walk to North Beach in SF and afterwards would go to the beach chalet brewery across the street to have a few beers. I was way out in the water one time and looked back to see some guy stealing all my stuff. Canceling all your cards is a bitch. An implant would have solved that problem.

Actually putting chips or implants already sound like something archaic. Due to the great advances in quantic computing it will not be long before we do many things with the simple power of thought.

You can literally already do this exact thing with a NFC tag. Just cut open your arm and slap it in. Done. Oh maybe don't forget to sanitize the area before/ after or whatever. I'm not a doctor so idk the procedure!

downside of just an NFC chip is that it transmits one message at a time. so something in your arm without any 'processing' ability will end up just transmitting a private key. allowing any receiver to be the signer.

a better concept is either wait for microchips to have the power to see an unspent, sign a tx and send out only the signed tx, to be implanted. or make a device that can do it .. like a wristband.. that doesnt need to be USB cabled to a PC and doesnt need browser plug-ins/desktop clients to manage the receiving/sending.

that way the private key is always protected and also you dont need a pc for your own use to send a tx.
also you dont need something implanted by your doctor.

however.
i dont see an implant right now being a payment mechanism itself.. i do see an implant in the wrist can be locked to a password so that your wristband only functions when you are the one wearing it.

I can't imagine it happening, for me it's disgusting to insert foreign objects into the body like cyborg :D and it may not be good for the body. although for the protection of bitcoin i guess it's not better to do

I'm not agree with this idea. Everything that was implanted to our body is very risky in our health and maybe one of the 'cause of our death. What is the use of our brains if we couldn't invent the software or even hardware for the security of our bitcoins. That was a good idea than implanting bitcoins.

How do you get to the beach? Car/bike, just lock it up in the vehicle you used to get to the beach. You can also just buy a swimsuit and get this sown into the clothing. Why do you have to get implants? I can already see the marketting campaign for this, "Never lose your wallet again, just hide it inside your body" ^hmmmm^ The thieves will quickly catch on to this, and they will CUT you after they have scanned you, to get to your wallet. No thank, leave this to the attention seekers. ^LoL^

As I said, there are many other ways to do this that would not require you to cut into your flesh and risk infections and rejection.   

Now imagine if someone rich thought it would be a brilliant idea to store their millions in a microchip inserted into say, their hand.

Cue machete wielding man slashing off hand to attempt a brute force crack.

A payment chip in your right hand or forehead is not the mark of the Anti-Christ if the currency behind it is optional and not something that you are forced to use. Since when did any government or anybody tried to force you to use Bitcoin?

Im thinking of this kind of stuff too on which we could really easily make transactions with bitcoin with just the use of our own body (Ex. Arms) but as you said the security would surely increase but the risk of being robbed out is still there specially when someone knows that you are bringing your own bitcoin wallet.Someone could easily take you down and steal all the bitcoins you have.

given the impact of bitcoin, I guess have a bad effect and impact both. it makes a lot of transactions fast on the internet, in addition, very many people who can be independent when bitcoin know, in fact, many unemployed who now has his own business. but, it also had a devastating impact, because it makes the traffic of illegal transactions increased.

What happens when your private key is compromised? Do you have to cut it out of your body?

Same goes for these weirdos who get bitcoin address tattoos.addresses ain't designed to last.

That's basically 6th Sense technology by https://www.youtube.com/watch?v=YrtANPtnhyg .

When you say a chip,it sounds vague and makes it less technical to support your concept.A microprocessor with memory registers makes sense.

Does that mean I will live with a constant fear of getting my ears sliced ? Not sure if I'm okay with it.How do you send bitcoins ? Where do you type the amount ? How does your chip connect to the internet everywhere you go ?

A lot of complications is all I see.

I think that's probably a gradual implementation of the mark of the beast. I just read revelation 13:11-14:1-20 and I hope you're not in any way suggesting this so that a (world super power) may arise to use against the saints.

I don't think that's a very good idea, because having a chip that contains most of your bitcoin keys implemented into your body opens up a lot of possibility for hacks and money theft , they can walk past you scan your hand and then walk away since you said all the you have to do is pass it over a scanner and the money is paid 

I walk to the beach. I already said that. If someone wants your money they will figure out how to get it.

http://pbs.twimg.com/media/CxKhnV0UcAAZPtS.jpg

doesnt quite work like that but im guessing you have been watching a tv show that mentions it, possibly about conmen, gypsies and psychics

This is what im telling about earlier on which the risk of being stolen or robbed by some people is still there and as you mentioned they could easily lure you out to give all your bitcoin with the possible ways that will work like what you said on blowing a drug or any other like robbed you out with the use of other harmful things.

Wow, that stuff would work great for divorce. Instead of paying alimony you just blow some powder in your ex-wife's face and tell her to jump off a bridge. LOL 

put it this way
if they have to ask a street busker who has to play a bamboo flute to get enough pocket change to feed himself. he doesnt really know himself how it works, otherwise he would be rich. as for the story of the doorman saying the tenant helped thieves carry his possessions to the thieves car.. im more inclined to say the door man drugged the tenant and called his mates round to raid the apartment while the tenant was passed out. telling a little fib the next day to counteract his own involvement.

it doesnt make you lucid/articulate and able to function normally minus freewill, it is a roofie/super drunk drug. it makes you passive and not fight back. like being stoned and just wanting to chillout/relax/sleep. not become a robotic mind controlled zombie.

the reason its used is that unlike a roofie that requires you to get acquainted enough with a person to hand them a drink, you can blow it in their face just passing by, and within a minute they are drowzy and drunk

even when drunk via alcohol. i could easily say "hey mate we got a taxi home but the driver needs to be paid. whats your debit card number." allowing the drunk person to, while inebriated type in their number. because even when drunk that seems rational/normal thing if you see yourself in a taxi.. ofcourse the person sitting with you sees what buttons you press to later take your card once the taxi has drove off

this doesnt mean loss of free-will while remaining coherently/lucidly. its just being so drunk your easily sold on something that sounds rational.
however if i said to a drunk person you need to empty your bank account or carry your tv down the stairs to my car. thats a different story, most drunks would laugh and say "f-u i just wanna sleep" and then leave the thief to carry it themselves.

as for telling your password to a crypto wallet.. if the password is short enough for an inebriated drunk to spell it out.. then the entropy is not that huge anyway.

---

but this is why i still think wallets need to lock privkeys to something tamper proof and use public keys and signatures as the only publicly transmitted info.

EG BitID as the 2FA for services where the service shows a unique message and you reply with signature of that message that can be verified to a public key registered to you.

retailers see your public key and give your hardware wallet all the unspents of it. and your hardware wallet signs a tx, to only send the signed tx back to the retailer. thus the hardware wallet doesnt need an internet connection or desktop client with addons to act as a middleman

I don't like this idea. I don't want chip anyway in my body under my skin. First of all people adopt bitcoin because they want to be free from banks. If a have any kind of implant device in my body except this which is relevant with my health like as  a pacemaker I would be free from banks but slave of the bitcoins.

Today this idea seems fantastic. But I think that in nearly future such kind of ideas can be real. I don't want to think about all ramifications of this implants. In all movies such things hadn't a good end.

How about ur wallet, physical wallet? Why going to blood & gore stuff if u don't need too?
I don't like idea of implants, its too physical when its no reason to.

Well isn't the idea of having a phone with your wallet app physical enough? What I mean is that isn't it the idea of having a wallet app to be portable and you can use it anywhere?  Also mobile phones are enough because they show your transactions, they show what you have, you can send or receive money. Putting it in your body might make it worse in terms of features.

I've been concerned about this, due to the fact that a thief could just get access to your Bitcoin by either cutting it from you or just obtaining your private key.

In the case that your private key gets compromised, I think that an ability to replace it would exist since it is based on NFC technology where you can overwrite the chip with any data you desire.

As for tattoos, they are mostly QR codes which lack the ability to change them, in contrast to NFC tags or chips. Only time will tell whenever these implant methods become successful or not.  ::)

What will happened if the boby part was photograpgh and the person have access to your wallet, because this must be in  a public part of the body. I don't think it will work

Well I think this might not become a possibility since it would be using NFC technology. That would apply in the case of QR codes. However, to really get the data from NFC, it would be either by using an RFID detector or an NFC reader that someone carries along with him.

Nevertheless, I think that if the private key would've been encrypted from within the NFC chip, it should be no issue if the their ever gets access to it.

Also, another thing worth considering would be the health implications it would have, thus limiting its ability to become widely used in the mainstream world. Just sharing my thougths.  ;D

I don’t know about bitcoin implants, but I heard of an identity chip that gets implemented into your arm and a lot of people have rejected this idea because it compromises their personal lives and their security and I think that would be the case with bitcoin because you are holding your account information that can be easily be scanned and hacked which is not a good thing.

This is exactly why I use passwords that I could never memorize. Ok well there are lots of better reasons but this works too.

If someone asked me while drunk what my password was I'd say I mashed the keyboard and made sure there were special characters all over. It's like 30 or 40 characters probably. Good luck!

Yeah that may be the concern of most people out there. Security is key here when implementing this kind if system, especially when you have a very valuable asset such as Bitcoin. Another factor would be the health implications that this would have, greatly reducing its ability to becoming mainstream sometime in the future.

Still, it would be pretty neat to have a system like this as a matter of convenience, that would allow you to store and spend your digital currency, anytime and anywhere. I think that security would become of utmost importance, if such system would gain traction. Just sharing my thoughts.  :)

Abit of topic but how is he a fearmonger for quoting the bible?  He didn't even interpret anything ?   i hate when people just brand someone with a label instead of debating the point  :-\

Ok, I'll debate it. Why bring up that passage at all? Most of the christian bible is designed to instill fear. The bible doesn't say things like, "don't do that because god will be really disappointed and pout if you do". No, the bible says things like, "don't do that or god will allow you to go to a fiery hell and be tortured for all eternity". WTF?

This forum is called "Bitcointalk" not "Christians intrepret money". It's a financial website discussing a revolutionary monetary tool. Keep that christian fear-mongering shit in the circus where it belongs.

Are there any Mormon Bitcoiners?  ;D

ROFL

Don't even start   ;D

I think in the future the possibility of implants to pay for stuff and not only this, but having your entire financial, social security, ID... alll your government data may be implanted at birth and this data will be hosted in some sort of centralized government blockchain that will also have the token equivalent of bitcoin (e-dollar, e-euro etc... if we don't go towards a global centralized nightmare like the "phoenix" as predicted by some that is)

That already kind of exists in the USA and the dollar is already a global currency. I can't remember the last time I visited a foreign country where having dollars wasn't good enough. The USA uses citizen ssn numbers for everything (buying a house, opening a bank account, registering your car, getting a drivers license, etc.). Almost all citizens have finger prints on record which is a biometric record of your identity. You don't even need an implant to have bank accounts biometrically linked to you, they could just link to your fingerprint or retinal scan. Having a Bitcoin implant holding spendable funds that can't be taken away from you could help defeat the centralized financial systems that exist today. People just need to decide to accept it as money worldwide and use it for everyday purchases. Bitcoin could be a hedge against the "Phoenix" new world order money ever coming into existence.

just call it what it really is... hyperledger.

dont be afraid to call it by its real name

The idea of implants may see futuristic for someone, but I'm sure that it's our nearly future. But I think scientists are already working on the first prototype. Soon such things are going to be as something usual.

That is very interesting and I have also though of this. Though for me personally I worry the device fails and I need to be cut open again.
Or.... Maybe the device can be I jected into with a syringe ? I'm not sire sure but wither way my dear is it fails and then I need to be opened up again. I dont like the idea of hospitals .

simple ID implants already exist.. look at the implants your pets have for IDChips

but if your talking about something like the movie 'in time
http://images.tmcnet.com/tmc/misc/articles/Image/2013/tikker1.jpg

yes not something many would want

It's no worse than getting a shot. Women have been doing it with birth control for years.

That is certainly true. ID implants have already been implemented, but can be further expanded by allowing other data to be stored right within that microchip under your skin.

It can contain medical information, as well as access to funds (like Bitcoin), personal information, and many other things.

However, it could be very risky to hold onto your info within your skin, if it manages to become just as the concept that appears in the "in time" movie where anyone can just steal your time or in this case your hard earned BTC.

If this would be something to go viral, i'd say that security would be the top priority for this kind of system. Just my thoughts.  ;D

All this talk about the movie IN time, made me think about some experimental coin based at it, this coin would be made mostly for fun as the movie coin sucks and this one would suck too.

The coin would be like this:
There is no upper coin limit, unlike most coins.
Every X * 25 seconds, the system give (X) coins to a miner.
Every (X / 31540000) seconds, the person lose (X / 31540000) coins.

Explanation
At the movie you need 25 years to get 1 year worth of money (1 / 25 = 25), thats why wait X *25 seconds you receive (X) coins.

Every (X / 31540000) seconds, the person lose (X / 31540000) coins, to represent someone losing one coin second each time second.


Now thinking about it my idea assumes that each 25 years, just one person become adult, and that was obviously not the case at the movie. You would need to change X

Interesting idea, mate. This would well fit into a new cryptocurrency, whose purpose would be for time issuance that will help determine pay rate, life expectancy, among other things. It would be very surprising if this becomes used at a point where it could determine your lifespan (like in the movie). Perhaps, a cryptocurrency with above characteristics using blockchain technology to track every people would become ideal for it.

Nevertheless, something similar like this could implemented for Bitcoin, but in the sense where you could see your current holdings, as well as BTC's network stats. The possibilities are endless, but it would be up to mainstream acceptance from everyday people. Just my thoughts.  ;D

It would be not convenient for people to do so. Right now I have watched a documentary about it using chips implanted to the hands to do bank transactions, until now there is no development of it, it seems like it watered down. From my point of view people are not in favor of having such technology that require altering there body just by doing bank transactions or anything a like.

That sounds pretty scary. If thats the case then someone can easily kill you and get the cheap and used it in their own interest instead. Aside from that i dont want any implsnts in my body(this can also be used in tracking me)

Well that is the other side of the story. But yes it is very possible and maybe some technology is already here. As far as I can remember in a movie Elysium they have this cranial data / brain data  and it is implanted in ones brain,this chip stores important data :) I think its cool, but scary indeed as you may be a target of data heist and it may cost your life.

Yeah. But I guess that if there is enough demand for this technology to become viral, manufacturers of implants would strengthen security probably by using 2FA or any other method to help secure your funds. There is a possibility of implementing a multisignature address into the implanted device that would further increase security by requiring x out of y signatures to unlock your funds.

However, one of the things that I'm most concerned with is the health implications that this would have in the long term. If it is not safe for your body, then it might not become used in the mainstream world. Just my opinion.  :)

do you know the movie time is money? I suggest u to watch, and u can see why ur ideia dont be smart

Time is Money*

People who have enough time can buy what they want and live as long as they want, but if you do your  counter goes to zero you die, you can transfer your time to another person if you want, just touching your timer. In the film it is possible to see that there are "time robberies" for miseres credit weeks. What would stop someone from ripping your arm off and taking your bitcoins?

and if u die, where's go ur bitcoins?

Bitcoin implants? haha well it sounds not to be true or not to be done. Because embedding bitcoins is very hard to do and it seems it would take a longer time to make this. But we are industrialized country now, there is also possibility that it could be done if the people would focus in embedding bitcoins to something.

That movie has a weird way of talking about business, money and life. But it also serves as a warning to us and a reminder that if we allow the currencies to rule our life the poor people will be just a livestock that has no value and right to exist. If sometime there will be chips implanted on all humans then that will be the time that we will lost our freedom as our lives will be dependent on the state or to the governing body. The one who has control over the system will be the master of the world. Somehow having the microchips implanted on us is the sign of the apocalypse as the christians would say it.

Well it does have a point but we wont really reach up on this state on real life I guess on having these microchips thingy and speaking on the topic itself on where you would implant your wallet on your own body to make transactions lot more easier and faster but the risk of getting robbed is high specially when someone knows that you are holding huge amounts of bitcoin on your own body anytime someone would really harass you out just to take those bitcoins from you.

Why should we agree with this kind of idea? I am not in favor and would never agree with this thing and put something in my body.
We can use bitcoin anywhere we wanted and in the future for sure it would be widely used with a fast transaction so there's no point that we should have it.

Well, face the reality that it is now the way of other people to store personal data, passwords  through implanting chips but it is a big NO No for me.

Well i never said that i agree in this kind of things, i just said that there's a possibility in doing such stuffs. There are some rumor that there is one person implanting micro chip in his body (i dont know exactly who he is), but not exactly a bitcoin chip. Of course it is a big NO for me, i just share my opinion and that's not a big deal though  ;D.

Nice idea. A bitcoin wallet integrated in your body but I prefer a bracelet type like the one I see in the Passengers movie. They just let their hand near a scanner and then the device is synched with the computer. Pretty convenient and it's very doable because we already have hardware wallets. We just need to make it smaller to be implanted under the skin. A bracelet type would be easier though.

for a lot of poeple there cell phone is an "implant"
it literally never leaves there side.
when they forget it at home, they might experience panic attacks.

so there's no need for an implant, cell phone is just as good if not better then an implant, for all practical purposes

It would be rather hard to implement a full wallet into a human body. The chip would need to store both the private and the public key, be able to create and sign transactions. The chip has to differentiate between authorised transactions and unauthorised ones, for example, someone can just hold a phone to your hand and they can instruct your chip to send the Bitcoins to an address. Definitely possible to implant a chip inside your hand but it would be expensive and harder to develop.

It would be easier if it is a NFC that broadcasts only address information.

It is sound so good.
Putting a code in your hands or part of your body but it is dangerous for sure.

I personally not agree to that idea, harming your body to implant chip is not good, even though that idea making payment and other identification become easier, but implant technology into your body is not a good idea for me and it sound a bit scary

This is not that impossible it is just like putting chips in your body. But the assurance for the health of people is a bit dangerous like the radiation in every transaction you made, there is always a radiation to transfer the code they need from your chip.

if true it happened to put a chip in the body whether it was for a long time did not provide for the effect that install these chips

Bitcoin Implants are already around in the world. There was a video where a guy had Bitcoin Implants placed into his hand and he scanned his implant on the scanner to get what he wanted.

YouTube Video: https://www.youtube.com/watch?v=pdauofdGFBM


Many think that this is the what the mark of the beast is, they might not be correct because Bitcoin Implants are only a payment system that allow people to for things using mainly USD as a price checker.
Bitcoin Implants is the start of the NFC chip payment system's that allow people to pay for things using certain body parts, when the real thing begins this type of payment system will get used by many people of the public and they would not even know the 666 part.

may be such kind of activities are possible in modern countries but in local area or poor countries they do not have the facilites of modern science and technology.

Well, a bracelet would be much safer for sure, but it will lack the convenience of carrying your wallet inside your body, letting you send/receive your Bitcoin at any point in time. Also, thieves would notice the bracelet (since it is a wearable) than the integrated wallet microchip.

Still, the idea is not bad, and it would be much more handy than having to carry with a hardware wallet around. The bracelet might look like any ordinary bracelet, but instead it will be much like a discreet hardware wallet which you can use to safely store Bitcoin and/or any other cryptocurrency. For this to go viral, it would need to have strong security, in the case of theft or loss. Something like multi-signature, or 2FA will do the trick.

Nevertheless, implants or wearables, we are entering into a society were digital payments and automation will transform our ordinary lives. It would not be surprising to see a government one day, that would require its citizens to use some kind of implanted device that will contain personal information of an individual, as well as his/her funds, and more. Just sharing my thoughts.  ;D

This seems to me a bad idea. If you used to steal purses from handbags or pockets, then you will cut off your arm or leg with a bitcoin purse, such as implanted device, to steal money. I would be afraid for my life.

You want to lose your arm? Because that's how you lose your arm.

Imagine you're in a sketchy neighborhood and people know you're carrying a huge amount in your palm.

Its good for ease of transaction, but a big NO for security

yes you are not a robot  you are sensible person and it is really  not a good idea to har our body. to me if it is o much important then you can use some other ways of using the chip for the purpose.

That could happen but if the implanted device has security mechanisms like multi-signature and 2FA, then it would be really hard for anyone to steal your Bitcoins at all, especially if you would require x out of y keys, to unlock access to the funds. The possibilities are endless here, being the only limitation the health implications that it would have if remained permanent on your body.

Nevertheless, it would be interesting if this tech becomes used in the mainstream world, as it would facilitate making payments in any kind. Just my opinion.  ;D

Reminds me of those news stories about h4x0rs stealing wireless credit card data from people on the street.

http://i68.tinypic.com/rszrz8.jpg

An implant would probably be the most convenient and fastest way to pay for things.

But perhaps like 2MB block sizes, the fast and convenient way, isn't always the best.

It's possible to happen and already exists with another id informations. They implant a chip inside the hand and it open their car, house, access bank account, make payments, everything... But I don't like the idea, we never know who is watching us.
I prefer to keep my body clean without anyway to track my movements.

Couldn't there be a problem with people hacking the data on the chip. I wouldn't trust the security of something like that, but it's not a bad idea to start with.

Yeah. If manufacturers of the chip don't employ strong security methods, then it would be prone to hacking and theft of funds. To be on the safe side, they could choose to make the chip require a number of private keys (like multisig) to unlock the funds. That way, when the hacker of thief tries to steal your Bitcoin over the chip, they would have no luck doing so, since they would only have access to a single key, while the rest would be required to unlock access to the Bitcoins stored on that chip.

I believe that as technology evolves, we would be able to see microchips implanted into every people, where it would contain your personal information, as well as your financial information. Probably, by that time governments would issue their own digital currencies, eliminating physical paper money once and all, and bringing the convenience of digital payments, all within the microchip embedded into your body. This might be not far from becoming a reality at some point in the future. Just my opinion.  ;D

hahahahahah u alright

As far as I know that implanting in our body is bad to our health. It will become risk in our life. We know that we're coming on that time. When it become popular and anybody implants in their body, I don't think I would do that. I am scared of the side effect of the bitcoin implants. I am happy of what I am using like gadgets to keeping my bitcoin there. It's risky because of the criminals, they will let you die to get your bitcoin.

hmm sounds like a good idea, but i imagine for it to be a multi address wallet it would need some sort of battery source and chip to be able to generate new addresses otherwise it could just be a single qr code for one address.

I can definitely see some security concerns arising from this, but the scenario you're describing seems a bit more on the fantastical side. It would be pretty difficult to keep a cut-off arm hidden enough that you can fake owning the arm and pay for stuff, but it is possible and, even if the attempted robbery is not successful, it still maims people and results in them losing a lot more than just a wallet.

I've never been a fan of rfid chips, and likely I will never advocate in favor of them. Too many things can go wrong way too easily.

And why do we need to have such an implant in our bodies? What kind of advantage will that bring?
wouldn’t that put our anonymity at risk since your addressees will forever be linked to you since the implant now is part of your body?

Well, it will bring you the convenience of not having to carry or wear a physical wallet with you all the time. You'll never forget to bring your wallet when making payments with Bitcoin as it will always be inside of you. I know that it would be a huge target for thieves to try to steal your money, but I believe that security mechanisms would be deployed, to prevent this from occurring.

Something like multisig that would require the approval of at least 2 out of 3 keys would greater strengthen the security of your implant. It could be the combination of your smartphone and implant to help unlock your funds, or using any other device you may have registered.

On top of that, if Bitcoin scales and becomes faster in transaction confirmation times, making payments with your implants would be a snap. While the implants may not be a viable use case nowadays, I believe that it would become used at some point in the future. Just my opinion.  :)

Not sure if I want to incentivize someone cutting off my hand or digging in it with a knife to get to my wallet.

I do not want anything implanted on me even if this makes paying with bitcoin faster. There are hardware that can do that, and it doesn't have to be planted on my body. This reminds me of the movie In Time, where the time left in their lives is in their wrists. It is convenient to spend and also convenient for others to steal.

I guess, before trying to make some crazy ideas about implementing bitcoin wallets into our wrists or having a digital wallet in our pocket, people should work on making bitcoin accepted anywhere we go.

All the business in the world should have a motivation to accept bitcoin therefore they have to know the advantages of using bitcoin nowadays, we don’t need any crazy ideas until we can use the bitcoin in our daily lives, it is like bringing a suit to a beach party or it is like having a fork to eat soup you have it but you can’t do anything with it.

They wouldn't have to do that because getting your implant wouldn't give them access to your coins. They would still have to know the password, so this would have to be a typical armed robbery where they incapacitate you, hold a reader to your arm to make a payment request and then hold a gun to your head or a knife to your throat until you enter the pass to confirm it.
I don't think that having a wallet implanted would make it easier for the muggers to steal your money.

but if the only thing being transmitted from the device is a signed tx  (emphasis no privkey)
then it ends up being safer then a credit card

Looks like a very attractive idea and can really be an icon for being a very technologically-advanced person. However, there would be many who can be turned-off with the idea. I for one may not go with it as it can invade my own privacy even if it is just my thinking. Plus it can be dangerous...we can be kidnapped and be forced to do Bitcoin transactions because the chip is inside of us lol. But I think there can be a good market for this and the technology behind can have other uses too. :)

Well, this is interesting, in medical terms placing a foreign object into our body is potentially a disaster. If this concept just like something that implemented on the surface of the skin i think this is not a big problem but if this object is placed under the skin layer it's just not good for your health. Not only that you might also lose your arm you know what i mean, the criminal will do everything to get what they want.
Anyway, bitcoin tattoo is a good option sadly it just can be used to receive bitcoin.

I think these will be great, I mean really great, and I think we dont need to use private keys because we can use our thumb mark as our private key, right? what do you think? everytime you pay your client or costumer you will just give out your finger and mark so it can be sent. As we all know bitcoin is the most innovative currency and it also need some innovative security, these is really great, I think someone has been implementing these now.

I heard from rumors that in my country several personalities have microchips implanted somewhere in their bodies to trace where they are in case they get kidnapped or something. This has been a rather old technology but if payment system is to be configured in that chip, that is definitely an upgrade, and that also raises the security issues a person has to deal with. Maybe in the future, these things would be possible on a wider scale because implants are starting to be just another thing at this day and age.

So in case you want to send or receive some BTC, you would just pass your hand over at a scanner and it would perform the desired operation. This is would make it a very convenient and easy way to transact, and carry your Bitcoins with you anytime, anywhere. However, the only thing to be considered would be the security of your private key from within your implant, to protect your funds from theft.

Nevertheless, I want to know your opinion about this, since it would be pretty cool to have such a system to help spread mass adoption of the cryptocurrency.  Smiley

I think this is a good idea, if there is now perhaps this will facilitate transactions for users bitcoin

Thank you, wont they have to operate ones body(hand)? if that will be needed, Why should we go that far? and if not, technology can go that far if accepted and that will be a nice idea.

Ive heard that same concept i think the name of it was RFID microchip, cant remember.
But if ever it happens that would be the end of privacy for us bitcoin users
Cause they can track us using that device where ever we go
That would destroy bitcoin's anonymous features.

This is simples, you just make it so you have to clap both hands together before making the payment.

The idea is great but I'd rather use a watch, armband etc.. that has my private and
public keys on it, I'd be more comfortable with that. although if bitcoin bio-paying is accepted
and is approved to be safe, considering it is not a problem for me :D

Well, if such an implant be visible from outside, you probably be kidnapped...

The chips are designed not in RFID or GPS type that can be tracked, but the implant in form of a barcode
it is actually not difficult to indicate it but I believe there is no such thing as anonymity in the future
everyone will be recorded in detail if they want to be accepted by civilization.


Innovation has always had a lopsided argument, but it doesn't matter because if you carry a credit card will also experience the same thing.
Crime is always there and that's where we need to be more vigilant, implants offer a more practical concept and automatic.

>People are implying that we're actually going to get to a point where RFID chips are required in order to function in what would be a modern society.

While everyone wants to say that, I find anyone actually expecting it to be woefully unaware of the actual attitudes held by people that would have to deal with something like that, and they're ignoring the geopolitics happening right now.

Governments in certain countries will seek to do something like this, but there is a high chance that they will either fail, or in the event they succeed, it will not become a major thing for at least a generation in their country. Even then, people who don't want it can leave to a country without it.

It would be pretty convenient indeed but the thing is implanting something within your body might affect your health or something and every person have different immunity within their body that the implant may affect it but if, and the government would not be against this idea they it might be great but then I think we don't really need this things to be implanted to someone, just like in the movie kings men about the SIM card implants in their napes, I think the whole concept or idea came to that! 

Implant technology (non-bitcoin) has been used for detainees at Guantanamo, and even embedded in the body of war soldier, very useful to anticipate if it's lost in the countryside. For economy, I welcome this bitcoin technology to be quickly realized, maybe we don't need to carry a wallet + private key anywhere because it's embedded in the body. In this case, the percentage of the radiation has to be taken seriously.

Previously, we know many types of medical implant or implant chips in anticipation of fractures, this is 100% safe though made of iron and steel.

Yes. That would be the number one thing to consider, before implants become a reality. Bitcoin needs more acceptance from everyday people, merchants, and businesses to become practical in the mainstream world. Another factor that would need to be considered is the ability for Bitcoin to scale, as it would determine its long-term success in the future.

However, if Bitcoin gets to scale, then there would be major acceptance from merchants and businesses worldwide, making the use of implants practical in the future. I have the feeling that we would shift towards using implants and integrated devices to handle our personal information, as well as our finances. Just my opinion.  :)

I don't think it's a good idea because you could be tracked very easily for nasty people, like the government. They would track you by your address and you wouldn't be anonymous anymore. I know there are advantages like the accessibility, but in the end it's more negative than positive.

Currently, there is already this kind of implant, not with BTC, but with another informations, like a barcode micro chip in the hand. I wouldn't use this kind of stuff...

It's just a dumb idea. Keep your money separated from your body, or else your body may become a target for the most brutal thieves, you don't want to lose an arm cause you have a chip there with millions of dollars. Bad idea!

Come on it's nothing bad. Tell that to people that implant stuff under their skin to have horns and stuff. I haven't heard about them dying from it.
I wouldn't be afraid of the implant itself or losing an arm like someone suggested, I just don't see the point of having such implant.

You seem to have a point. If governments manage to crack down your implant, they could gain access to your Bitcoin. While the idea of having a Bitcoin implant sounds great for convenience, it may not be the most viable way to use in the mainstream world, due to security and privacy issues.

Perhaps, at some point, this kind of system would be used by governments themselves, to gain better control of their citizens in every way. All kinds of information like personal, financial and health, would be integrated into an implant, which you would use to access government services.

By that time, there would exist digital fiat currencies issued by governments, with the use of blockchain technology. The combination of blockchain technology and the use of implants, would be of great use to them. Just my opinion.  :)

who would want this bitcoin implants.. i think no one. :)

It already comes in your mouth and you just said that some implants have a radiation and if it is made with iron and steel if it rust it can go to the blood stream and can be fatal to the system well think about first before apply it! I think the native conventional way of transaction with bitcoin is OK and convenient in many ways we don't need this advance things so we can just use bitcoin so we could just sit still and make our tummy big! I think it is as good as it is.

Yeah. Taking into consideration the health implications that an implant would have, it would not be the most viable solution for everyday payments, but still it is an idea that might become a reality with Bitcoin, if security and health risks are the top priority when designing these systems.

In the meantime, I think that using conventional hardware wallets are great to use with Bitcoin, as there are no health implications involved. Not to mention the security issues too, as hackers and thieves will only target the device itself, in contrast to having the device implanted on your body.

Nevertheless, as crazy as having an implant sounds, it might not be far from becoming mainstream in the future with a digital currency which is backed by the government. I have a feeling that everything will be done (access to bank accounts, medical information, etc.) with the use of implants as our society evolves and becomes more futuristic. Just my thoughts. ;D

As in now days I already see some people in the new who started implanting chips in there body and they can use them to pay in stores with just waving there hand the a machine will detect the chip implanted in there hand and hes already paid in what he buy..,,
As now we are not sure if they will use bitcoin as the currency or wallet of the implanted chips but in the book of bible it is already ready happening and it will happened in the revelation..

it would be nice that way, but I think we are looking too far from the future the way we are talking things here, though it is a really good idea because it will be more convenient and less hassle than accessing first our web wallets before we can send transactions. But the problem is, what if somebody would remove the implant in our body, and steal the bitcoin on us, then it will all just go to waste, all the efforts that we spent in order to earn that bitcoin.

I think it would be more better if it is not going to be implant but it is connected online to our web wallet, in order to be safe and more secured.

How about security of that chip?
I have to ask because im curious if someone is able to steal bitcoins from him through some device or to find exploit in software.
If there is a way to do it, then it was not the best idea.

Im also not sure about health problems with this medical surgery to implant the chip.
Personally, I would not like to have btc chip under my skin :D

The idea of ​​a wallet installed in a microchip under the skin sounds interesting but it should be added certain security measures:
-The wallet could only work if the chip were under the skin, so it could not be stolen.
-The wallet could only work if it detects (in some way) that it is under the skin of a living organism. This would avoid hand amputations to steal.

There would still be the possibility that the user would be threatened with a knife or a pistol and forced to pay or that someone would devise a way to hack the wallet with a handshake.

The developers of this implant is not dumb about the implications that this may cause. For the radiation that will be emitted by the implant is so small that it cannot even harm the body. Our smartphones emit radiation and yet it does not do any harm don't they? As for the metal to be used, instead of iron and steel, they may use stainless steel so that they will avoid rusts or even other metal that will cope with that health concern. Having implants is not that dangerous to a human's health, that is why there are scientists and engineers. Also, I think this type of implant will not be implemented unless it is proven by medical authorities that it is not harmful to anyone's health.

It can be done, yes but is it practical ? Honestly, I think that is the dumbest idea I have ever heard of, no offense. The next thing you know everyone’s hand is in danger of being damaged :P. It could work but it is not really necessary and I think it would cause more trouble than it would solve.

QR codes are just as easy and don’t cost thousands of dollars like a technology that implants something in your hands.

Things like this have been thought if before bitcoin came about. It's a good idea and will work. It's a microchip it's out inside of a syringe and injected under your skin. It will work well but I personally would find it annoying just knowing something is there under my skin that I cannot see.

This is dangerous... People will get robbed of their body parts for bitcoin!

Besides, you will be linked to your bitcoin address(es) and may lose your privacy when making bitcoin transactions.

I am not supporting a chip under my skin and i really do not think that it is interesting simply because of the security and privacy issues and i do not want any third part to monitor my movements,but i am not sure whether you will be able to custom a microchip to identify whether it is living or nonliving organism,with AI advancing in the future there might be a solution .

Cool and science-fictiony vibe to your idea, the only problem, as others have pointed out, is that getting hacked would be a real bitch.

Also, wouldn't want to deal with someone motivated enough to take off my whole arm/hand, to access a key. You don't want to centralize this information in this manner; better any keys be in a way that you can divorce them of yourself should the need arise (being kidnapped or arrested, for instance). You would rather hand a physical token of this sort to someone rather than risk having it compromised/ stolen, having it as an implant is a bummer as far as operational security goes.

This is a slightly better idea as an otp generating device. Maybe tied to a person's biorythms.

It is not a fiction it is a real thing that has now prototypes in Asian countries the only problem is it died down because of having a few participation of the consumers. There is also some ATM machines that scan the veins of your hands before you can access your acount (every person has a unique vein structure just like a fingerprint). My main point is if it did not became successful to Fiat Currency why would it become successful in Bitcoin? Bitcoin already uses technology why would someone transfer to another unproven alternative?

Not all people are very resistant to this kind of radiation as there are still people with a little immune system in their body and not all are gonna be compatible for the process, but yes there are a lot of people that are gonna be compatible for this, but can we be true to ourselves do you really want something attach to you just like and yes Cellphone have little amount of radiation in them right now but not all people are resistant to some radiation that is why there are still many deaths recorded that are cause of a brain tumor or cancer these days.

I think that it is a good idea.

However there is really no need for this, all you need is a smartphone.

This would also mean that it is easier for hackers to gain the private key of the person using this implant. I simply do not think that this is a good idea, and when you see credit card hackers just walking by with a harmless machine but actually extracting your credit card details, you get chills down your spine.

If somehow security can be achieved, then this is viable. But it is also a permanent commitment to bitcoin for whoever wishing to get this implant done.

Yeah. I know it’s a crazy idea, which may be harmful in every way, but in the meantime, I think that we will do fine with hardware wallets themselves. Implants may be useful, as they will always go with you within your body, but they pose many health and security risks. I believe that the waves transmitted from the implanted device would have a negative impact over your body in the long term, resulting in cancer or something bad that will cause you the death.

But, if manufacturers take these issues into consideration, they could develop a safer way for anyone to use implants and transact with their currency of choice, without the worries of the health implications it would have, as well as hackers trying to get over your hard-earned money. This would greatly enhance its ability to become used in the mainstream world at some point in the future.

Only time will tell if this really gets adopted or not. Just my opinion.  ;D

implants no

first gen hardware wallets no

i see the solution as something inbetween (as posted weeks ago)

a smart watch that only transmits public info such as a signed tx.. (not private key)

I do not like implants, but paying something by just putting my hand over a sensor would be great, but I still think it is easier to control when you have a mobile wallet or something, you can still bring it anywhere and it is also easy to use.

Most people who think of the future concept of technology is to make people even don't wear anything !. All becomes simple when implanted in the body, so we don't need to use android or another computer, this technology is full of pros and cons but I still support, bitcoin civilization must step forward compared with conventional concepts.

Yeah. Even if implants are not the most viable method to use these days, it may be at some point in the future. As we advance in technology and innovation, new and efficient ways to make our life easier would become implemented.

Maybe, the implants used in the future would not be used for Bitcoin itself, but instead it would be used for digital fiat currencies as governments switch to blockchain technology. This would rely on already established public blockchains like Ethereum or on a separated private blockchain operated by governments themselves.

The possibilities are endless, but only the technology that becomes widely accepted by individuals, will become a success in the future. Just my opinion.  :)

A plus would be it is not good for our health as well imagine yourself wearing an metal implants or plastic or whatsoever. We can solve the ease of transactions without risking our health and implants are not the solution

Yeah it all sounds good in theory but I would much rather have the wallet on me so if it came to be being killed or giving up the wallet, it wouldn't take them cutting into my arm to be able to get it out and I'd just be able to depart unharmed from everything. Seems rather dangerous as people would just be attacking people for the chance of them having this.

Could do well, but I think this in itself would do more harm than good. Also, why's it so hard to just go onto your phone / Computer and use your wallet from there -- do we really need these implants?

Yeah right, it's pretty much risky for us, it is bitcoin, and we all know that is it too valuable if we are going to compare it to fiat, and implanting it on our arm is such a suicide, especially if we are on a not that secure places. I would rather to use online wallets than this implants which I am not what defects that I am going to get on this, that is why it would be better if we are just going to stay on the safe side.

Right. An implant for Bitcoin wouldn't be viable these days, especially with the digital currency's value increasing each day. Thus, the more valuable Bitcoin becomes, the more it will be targeted by thieves and hackers.

Having an implant on your body with a large amount of Bitcoin would be extremely risky, as your life would be threatened by criminals, to steal your money and perhaps kill you in the process.

In the future, we might be able to see implants not for Bitcoin, but instead for a digital currency which is issued by governments. Since security and stability would be the top priority, it will make it extremely difficult for any hacker or thief to get away with your money. Just my opinion.  :)

Well one of the best way to carry something is having it on your own body and making something a part of it. As we can see in the future in movies, people access certain doors and securities by using their hand and having some chip on it. Of course it's good but I think it will be more prone to bad people. They will cut your hand if necessary in order to steal.

I've heard some news about making DNA as a storage device which I think more reliable than implants. The bitcoins are in your cell not worrying about a wierd chip in your body. Well it's still all speculations and we won't know what happen for sure in the future. We still have a long way to go. Stay tuned.

Many people think of radiation, or criminals who cut off the hands of implant chips holders, but I think it's just like our wallet happens to be stolen by bad guys, crime is inevitable, but with chips and dna, monitored with gps system, The only reason I'm against this is our privacy will be lost entirely because our existence will be very easily found by certain parties because of the gps system contained in it.

i don't see the rational behind bitcoin implants. first and foremost, whats the importance and use of these implants? can you enumerate?

If not bad what is wrong for health

What's the point in an implant? Some sort of key embeded into your body can be extracted, or even brushed against to be indecure. What should be done is some sort of encryption of private keys through biological data, maybe a fingerprint or the like. If someone breaches the implant or knows your private key, you will need to extract it. Just a waste

The fingerprint a great idea.

However, this will lead to people 'robbing' others of their fingerprints. Honestly, it's not a good idea to keep anything directly on you. The best method is just put it elsewhere so someone doesn't get tempted to rob you.

It's already very easy to carry around a trezor wallet which is secure enough. There is no need for anything else.

Yes. Everything about implants is wonderful, but the issues of health and security are of utmost concern, rendering its ability to become practical in the future.

I would become surprised if such implant with extreme security becomes designed for the government's own desires, eventually leading to complete control over your finances, personal info, and more. Technology is constantly evolving each day, making proposed solutions become a reality sooner than we've ever imagined.

But other than that, I think that we're doing great with the hardware wallets. Just my thoughts. ;D

This isn't a new thread. For now, I hope you know this technology's operating in practice, in a few countries.

What would happen if someone hacked your implant? Or would get to know your private keys somehow?

Sounds pain to me... ))

Yeah. Those are the major concerns among everyday people, as having an implant would put their life at risk. No matter if there are health or security issues, they need to be of utmost concern before making implants a practical method for making transactions in the mainstream world.

For now, we would be doing fine with current wallet methods, but I believe that as society and technology advances, we might be able to see implants in our body in the future, when it becomes mature enough towards mainstream use. In some way, manufacturers would devise new security mechanisms, to ensure the safety of using implants on everyday people.

As I've stated before, it might not be Bitcoin, but instead a digital currency issued by governments themselves with their own implants and a full-fledged blockchain system. Just sharing my thoughts.  ;D

You can always change your implant or your personal key for the implant but godspeed doing that with your fingerprints.
Also your fingerprints can get damaged, you can always have a new implant.

That is the worst case scenario and it will happen if chip implantation will be implanted. I dont want to imagine a chip implanted on my hand and a robber will not only steal my chip but he will cut my hand off. Much worse if the chip is placed on our heads then we can say that our heads will be rolling when the bad guys comes to steal it. For me we dont need chips and web wallets as well as app wallets are the best way to store bitcoins.

Yes. Having an implant is too risky, especially with an asset or currency like Bitcoin which is highly valuable. It would be a huge target for theft, exposing the risk of death. Also, it may break anonymity when using it, which goes against Bitcoin's value proposition.

I was only talking about implants for Bitcoin at first, as a possibility to become a reality, but I guess that the health and security risks prevail, making such concept not practical for real world usage.

However, as technology advances we might not see implants, but rather something that would be even better, with security and health over its users in mind. In the meantime, we could focus on using hardware and/or software wallets, as they provide all the necessary functionality to send and receive Bitcoin. Just my opinion. :)

We should also think of good idea with constructive criticism, not all robbers will know if we wear implants or not because this is still privacy, If we talk 100 years ahead of course the use of implants will be in accordance with era development where radiation and global security system is adapted to adapt the implant. Developers will also think about anticipation if implants are used unreasonably from robbers (hand pieces etc), then their chip will switch off by itself using gps system. I think using bitcoin implants also requires keywords to perform all transaction.

I don't see any necessity in it, nowadays people are carrying their phones wherever they go and there is no problem with making transactions using them. And by the way, such a microchip might be rather expensive, so it would be protected from destruction inside your body by enzymes or free radicals and still be able to recieve and send data through your skin layer.

Yeah. Maybe at some point in the future, this would be practical due to the advances in technology. New security mechanisms would become implemented, reducing the possibility for theft and bringing the convenience of carrying your funds, personal information, and more.

But, until today, we would be better off with hardware wallets, as they're proven to be the most secure way to store your Bitcoins or any other cryptocurrency. There would be no need to worry about the health implications this would have (unlike implants) since it's a separate device operating on its own and not into your body.

Nevertheless, I'm looking forward to seeing cryptocurrencies like Bitcoin become practical in real world applications like: Grocery shopping, filling up your gas tank, and even more. The future is unpredictable, but it's cool to imagine what it would be like with the high advances in technology. Just my thoughts.  ;D

If it did not work on Fiat Currency why would it work to a cryptocurrency? Like what I said earlier chip implants was created before for you to withdraw cash in atms but was surely taken down after no consumers are willing to use it. And what I am seeing right now is that Bitcoin is better off im what it have now in which there is a Bitcoin Wallet app that is portable and also secure. I don't think that an implant would be any better in terms of security.

Thats already coming with the new one world government but it wont be bitcoin it will be government currency. Its called the mark of the beast - 666.  That is the first thing I thought when I saw bitcoin.

Scary I guess?

really? i don't really sure about this and until now i don't see that its related with 666 like you said or maybe if its true, then i don't know about that. for me, as long as i can still continue involve in bitcoin industry and i can make money from bitcoin, then i will continue to earn as much as bitcoin that i can. but if i think something is wrong, then maybe i will considering to stop for a while.

I would say very scary. I guess we will see.

Yeah me too. Due to the high advancements in techmology, and the emergence of Bitcoin and the blockchain, it opens up new possibilities for a new world government to rise with its own digital currency using implants on their citizens.

As the blockchain has been proven to keep track of transactions, property ownership, and more, it makes this closer to becoming a reality in the future. Governments would have more control over their citizens, greatly disrupting their privacy. Just my thoughts.  ;D

Chip implants were tot created for withdrawing cash.
The first reason was medical data in case of emergency.
The second most used chips were for security reasons , access to buildings or restricted areas.

And a chip implant is currently more secure than anything in this world.
The most advance come with triple security so you still need a pass and a finger print or retina scan after it so it's next to imposible to duplicate.
Your phone can get stolen so easily it's ridiculous.

Wouldn't you feel better without having to worry about it?

Nobody is implanting anything into my body. Ever.

What the fuck?
Chip implants are only being conceptually used for security access reasons by a single company, there is not another instance of chips being used in the other ways you mention. Most of them are unnecessary and you can't use a chip implanted in your arm like a phone.
Are you sure that you're fully aware of what chips even do? What they're used for and when they're used?

The concept I think is barely a barcode, and it's natural for people to think of more brutal crime like hand-cutting, but I think of the authorization system where if the implants still require a private key or password in use, it doesn't matter. GPS concept has been applied to some detainees at Guantanamo, but I don't really agree because GPS will only make us a doll that can be monitored by others at will.

The OP wants an RFID bitcoin wallet? Did you know that someday this will happened? This is the bible prophecy that no one will buy or sell without the mark of the beast (Satan). Someday all cryptos will be wipeout. And people will use a centralized money. As of now people surely against it. But using World war III, the Illiminati could control the world.

If you dont have food to eat, no more shelter to rest. You will submit to the anti christ.

And this is the reason why I'm not in favor with this. Aside from the possibility in health problem if we implant some chips in our body, the thing is it will endanger our lives and be exposed to risks because of this vulnerability. Since the chip is implanted in ou hand then you can just cut it open and get it then if there is password or similar like they can just break it, blackmail, or hack it maybe? We should consider really the possibilities, the advantages and disadvatages, and the risk it will present to us.

I wonder why we have to be monitored by a GPS system, I mean is in our current monetary system right now ( called fiat ) we arenot being monitored,or at least they want to monitor you. There are what we called Cold Storage so you can store your BTC even if you are not online. The only reason why we need to go online is when we are sending or recieving btc. I agree with you that it will ruin our privary, nit just privacy, it will violate human rights. And I think before anyone will agree to the terms that BTC will become the new money, they will ensure that their very own action in their everyday lives is not being watched.

What a nice thing it is! A convenient one and a new evolution of technology. But still we need to examine it closely as to its effects whether its good or bad.

I'm glad women don't think that way. Some of my favorite times in life have revolved around late night implantations using my personal injector.  ;) 

Is that regulated activity? Do you do your KYC / AML? ;)

Oh yes, Know Your Clam / Anti-Menstruation Lobby is very important.

I guess that you do have a point in the security of implants. Based on the information you've given, it appears to be much safer than traditional hardware wallets if used for sending/receiving Bitcoins.

While hardware wallets can get lost or even stolen, with implants you won't have to worry about that since it's right within your body. No robber would even imagine that you carry with your Bitcoin implant on your body, as it wouldn't be noticeable by them with their eyes that easily. Still, it would be painful to place the implant in your body, but if it would be worth it in the long term without no health implications, then it would be the real deal. Just my opinion.  :)

but... and if u die?

The conveniency it can brought if this idea will somehow be implemented then there is no doubt but the security and the exposure of the holder to danger and threatening its life is the real problem. It has been developed actually and I read an article regarding that though others didn't consider trying it and besides they don't have a sponsor to mass produce it. Nonetheless, that would be futile. We should consider some other factors aside from conveniency then decide whether overall if this would be good or bad.

the ancient art of grave robbing will make a huge comeback.

and u believe that?

Yeah , prove to the entire world how ignorant you are.
There are a billion people on this world that consider this number to be a lucky one.



You have read a pretty damn old article it seems.
I know a person who has got this type of implant and he uses it for access in the company office and to store his medical data.

Nothing dangerous but highly useful when you have an emergency.
There is absolutely nothing life threatening about it.

Really interesting he nailed it. By seeing this thread I thought op is completely in imaginary world but it happened in real it's really awesome

Carrying a smartphone is all that is really required.
If people start carrying private keys on a chip you will see something like in a science fiction novel where criminals kill wealthy people to steal their microchip.
Carrying around a private key that is not encrypted and password protected would not be a very good idea.

First that chip can contain any type of data be it encrypted or not you can choose.
You can even have two chips that act like 2fa but I've only seen those in tests.

But the point is that you think people will start killing people to steal their microchip.
Forgetting that at this point they "only" steal your wallet and smartphone you really think people will start killing for that?
A chip is so easy to extract it makes no sense killing somebody over it.

If they would be that desperate they would kill you no matter how you store your wealth smartphone plastic cards bitcoins or gold.

and how u can use ur btc? A bank?

Yeah. The smartphone would be all you need to safely store and secure your Bitcoin nowadays. It doesn't have any health implications, and most of all, you won't need to worry about someone taking your life to get access to your funds.

However, while we may now see implants as a dangerous tool that would put our life at risk, it may prove to become very secure and convenient in the generations of the future. With it, faster and convenient payments would be handled by your chip anytime and anywhere without the need to carry extra equipment such as smartphones, PCs or even hardware wallets.

By that time, Bitcoin may not be the currency used for these purposes, but a digital fiat currency used by governments would become a viable choice for this. Only time will tell what lies ahead. Just my thoughts. ;D

Can't happen, there is no interface to use and that means you will need an outside way of controlling it, so why ever put it in your body in the first place.  Smartphones will soon control everything and while their size is restrictive, there are more functions using Bluetooth mics and the phone is merely carried on your person.
 

I don't know but I thing having Bitcoin wallet implants is uncomfortable. To think that you have some semiconductors underneath your skin, I makes me want to scratch my arm due to being uncomfortable. Some says that it is safe but I think I do not want one. Maybe some wearable tech of some sort will be good. Take a look at the so called "neuro-linker" on the anime Accel World, now that is cool.  :D

An implant is so small that you wouldn't feel it. I mean you can feel it when you touch the skin, but it doesn't make you feel uncomfortable or itch. I'm pretty sure we'll start using them at some point, because implants will allow us to do a lot of things with ease, like opening doors, cars, disabling alarms, paying, gps tracking and will help identify our bodies in case of an accident. They can even hold our last will.
I wouldn't put a wallet inside my body right now, because the technology isn't advanced enough, but my pets have chips under their skin and I would seriously consider chipping my kids to find them in case of abduction or something.

This will be possible. It is the sign of end times. That people wont be using money to buy goods and the things they need. If this happens only those who has microchip in their body will be able to buy things in the future. It's not only bitcoin that would be impanted but whole details of that person, the government will be able to track the location and finances of a person. This may sound amazing or cool but it is somehow not good.

For me I think it's good especially to those very developing country that can used this bitcoin implant technology and if no issues then maybe some country adopt this technology too.

We should adopt this technology if it is no problem with our health and for our own goods, especially to those wealthy personality that can afford this technology and have huge bitcoin savings.
But how about to those less fortunate people? I think they cannot used this! they just used old fashion way of trading using fiat or paper money then.
 

*Fast forward to year 2030*

NEWS FLASH:

Innocent guy in grocery store got robbed and got his arm cut for the Bitcoin microchip.

NOPE

I feel that the main human problem in the future is the uncontrolled population, no more land for aquaculture, and even for economic equities, in this case implanted chips in human body are needed to control the movement and human populations, this sounds creepy, but this an effective way to become a Solution and future effectiveness. Bitcoin is the solution for the economy because natural resources for the production of paper money/metal coins are extinct, technology is the last human hope.

yes that is a big problem that we are going to face in future, i think the changing weather is also another problem because the temperature of the world is increasing from time to time.

This is an unreasonable fear spread by some crazies, probably those weirdos from greenpeace.
Do you know how much land is currently uninhabited? I'm not talking about land with extreme conditions like the Arctic Circle, but normal land that can be used for farming.
The answer is a lot, more than we need and more than we will need in another 100 years of growing. If somebody decided to grow food in the uninhabited parts of Russia, he'd be able to feed whole Europe for centuries to come. We're not facing overpopulation problems, just some areas are becoming crowded.

I pesonally don't embrace this idea, I think there should be a limit between humans and technology and this is like breaking that limit for me... so I'm not a fan of the idea.

I wonder if you'll still talk about limits when you're in need of a pacemaker, artificial limb, hearing implant, laser sight correction and so on. If the limit should be putting a piece of technology into our body, that's been broken years ago. First pacemaker was implanted in 1958 and people have been using electronic implants for over 10 years.

Religious and apocalypse waiting nuts will fight your chip because they are simply waiting for something to call the mark of beast, and yours will work for that.  It is simply an unnecessary and overkill method to accomplish a quickly unneeded task. To be straight forward,I think there is no need for bitcoin implants.

It may happen this way, if implants become accepted as a safe and secure way for use in the mainstream world. With them, governments would have complete control over your personal, financial, and medical information anywhere you go. The implant would become a neccessity for anyone who would like to buy, sell, or get access to government's services.

Since everything would be powered by the blockchain, smart contracts, and AI, the system would be secure, immutable, and completely transparent, giving governments the advantage of tracking your transactions, among many other things. Perhaps, now we may not understand the true potential of implants, but in the future it would prove to be an exceptional tool to provide convenience, security, and reliability to people in a highly evolving society. Just my opinion. :)

If it's been implemented to have bitcoin implant we cannot prevent that to happen, but since bitcoin is not yet adopted and government still not recognizing it as legal currency; that possibility is still a myth for now. Mark of a beast has been prophesized by the religions linked to christianity so that should be respected and those fears are silently deeping knowledge for all who believed, and established faith with it.

How would you even feel uncomfortable?
You won't be able to feel it, simply you can because of how our body works.

And I just googled what you recommend.
That is 100000x more dangerous than an implant.
Reading from the wikia..


So you want a device that can communicate with your brain waves but you're afraid of an implant with static data?

I don't think that the idea of implanting chips in a body is a good idea. Firstly it is not safe for health, and secondly such actions you can make to manage your strangers. Then you will lose not only bitcoins, but also freedom of action.

Stupid ideas, they haven't figured how to use a new address and private key every transactions unless you could have a whole wallet integrated and

implanted on your body, I don't know whether any of you watched "Leftovers in an episode Kevin died here and woke up in afterlife as the president

Of the united states and they wanted to move him to a highly secure bunker and after all the usual verification processes he had to put his penis

On a scanner to make sure it's really him, his bodyguard said if they could fake your retinal scan, voice etc, they could never fake your penis.

Instead of implants why not use smart watches? anyways I don't think Bitcoin would be a great option for our normal and day to day shopping.

That is why I'd never use such a technology.  

I remember even ten yours ago or more this was being spoken about in my class st middle school. We discussed an Implant chip to pay for things. Then some crazy christian said it was 666 in the barcode and the mark of the beast so who knows

Maybe someone will havest your body for your chip ? Eek scary.

I love the idea, super science fictional and it is also definitely possible, I think in terms of mass adoption something like this wouldn't be implemented until we've also found a way of having our mobile phone within our hands, our ears whatever it might be.

If you gave me the choice, of chip in my hand or pay with my phone. I think I'd still choose phone, for now at least. Besides, someone might try and steal my hand, could get messy.

That does not sound good in anyway. Having a chip implanted under your skin or on your palm which is available for scanning to readily remove your coins during any purchase? That is a No No. Have you even imagined wrong people having such coin retreiving machines and kidnapping people just to use their machine to scan their palm and get all the coins they have? They can even decide to chop it off if they ain't that nice. Could work though if you will have to type a password first before any debiting occurs but still sounds kinda too risky.

Again with the dark age thinking.
If somebody would be ready to chop you in pieces to get your chip, he is going to chop you in pieces to get your phone now or your credit cards. Or to sell your organs.

Do you think people will suddenly start robbing and killing just because suddenly it might seems as being easier to rob people?
Where are you people getting those ideas?

Was there an increase in killing people for their necklaces when the gold price went up?
Who the hell would risk the chair to steal bitcoin this way? Cause kidnapping carries up to life in prison sentence in some places.

I think that this question should not even be voiced by the father, because any implants It is already too much. I understand and that Bitcoin is looking for more and more sophisticated ways of security, but it's already too much to plan any garbage.

I am totally against this and any kind of implants, whatever their use is. Hopefully most of the society is also against it. That is way too far, and against human dignity, simply.

For we are against about it and even me I don't wanted that kind of human intervention of technology development nowadays, that's threat to human life as well as radiations will is present of we are implanted with that kind of bitcoin microchip. But to think about we cannot go against it if it will become mandatory for the government to use that for security reasons; mainly taking out everyones privacy at the moment of your life, although it has a sense of security purposes but still freedom will not be like what we have now without any strings attached that you've been controlled not according to your personal will.

Implants. Hmmm i think you watch a lot of movies and tgat would be? "In Time"?
Scanning their arms to buy coffee for their time.

But this would be great and also scary.
Maybe that is why we are still on the paper money world because of things that might happen if all are just in one chip.
Can be easily robbed with just a scan and other hacking devices that could detect your chip.
This needs a lot of security first before going to the next level.

There are already scientists and enthusiasts using implant technologies to control electronic devices, or even to manage smart homes. So I think it's just a matter of time before something is designed for Bitcoin.

This is really dangerous. A bad person could even kill you after he/she saw the bitcoin implant on your body so that he/she can steal your bitcoin.

This is so appropriate for a Sci-Fi novel, or better, a version in which they exchange BTC for everything and is the only currency usable worldwide, The practicality? I think a hardware wallet would do exactly the same effect although less sparkling.

Yeah. Implants may not be prevented from becoming a reality soon. Perhaps, it won't be used in conjunction with Bitcoin since it is decentralized and governments would want a currency where they could have control over it.

But one thing for sure is that sooner or later, governments would make use of the blockchain technology for their own needs eventually leading the way towards the design of digital fiat currencies to be used with implants on every citizen. That way, there would be complete control of every transaction made on the country, adding transparency and reducing criminal activity such as money laundering.

Nevertheless, while implants may not be the most viable method for governments to keep track of your financial information, there could exist other ways to do so in a safe and secure form for anyone to use in the future. Just my opinion. :)
