I've seen that it's possible to interact with the Bitcoin blockchain using mesh network antennas, satellites and even radio waves. This is great, because it further decentralizes Bitcoin as we know it. But I'm wondering if it's possible to send/receive Bitcoin over Bluetooth? Considering that most devices of today are powered by Bluetooth, it's much easier for anyone to interact with Bitcoin this way than using satellites, and other means mentioned previously.

Do you think something like this is possible these days? If so, how can I do this with my mobile device? Any recommendations or suggestions will be highly appreciated. Thanks in advance :)

Is it possible to bridge the bluetooth protocol and the TCP/IP on which the Internet travels? I really can't answer this question.

It seems possible why not. As long as it can connect two devices, I think the transaction can be done. I have read 1 article and 1 video talking about a transaction over Bluetooth. Just visit these two links below:

- https://www.coindesk.com/bitcoin-box-can-process-payments-web-connection
- https://www.reddit.com/r/Bitcoin/comments/2jgg5i/pay_using_bluetooth_ble_instead_of_qr_code_with/

Bit old fashioned and compromisable.. Its possible to breach Bluetooth connections

When we make a transaction through Bluetooth the data gets transferred between the two devices, but there needs a connectivity that synchronize the data that's been received. For this active connection is a must, maybe this is possible but when we look for real time usage surely it'll lead to complications.

It would be possible if both of the parties are genuine to each other. The transfer through Bluetooth would be similar to sharing private keys between two users.
If the sending party is to do a fraud, they can claim that bitcoin before the receiver and transfer away as the real sync occurs only on internet.

You are not the first one to think about the possibilities of using Bitcoin over Bluetooth.

Offline Transactions and Bluetooth! (https://bitcointalk.org/index.php?topic=278237.0). It was an old thread, way back 2013. But it looks like the project had died down. To quote:

Sending Bitcoin over Bluetooth? Really??  How will the transactions be confirmed when it is sent over Bluetooth? Come on, the transaction of bitcoin can not do away with the use of the internet. Transactions are done worldwide and should be the need for a medium that connects the entire world. Bitcoin exist because of the existence of the internet. Bluetooth can't be used as a medium the connects the entire blockchain network.

Airbitz wallet is one of the well-known have Bluetooth features to send and receive Bitcoin but it is only for Apple devices.
Look at this old article from here https://edge.app/blog/bitcoin-nfc-tap-to-pay/

It was implemented in 2014 and the Airbitz wallet is rebranding to Edge wallet which is one of the recommended wallets from bitcoin.org.

However, the only problem of using Bluetooth your device might become at risk to any viruses and your wallet might potentially vulnerable this is a well-known issue on using Bluetooth.

Read this well-known Bluetooth virus before that may affect your crypto wallet: https://bitcointalk.org/index.php?topic=2172056.0

It may be a bit old-fashioned, but the point of sending the transaction via Bluetooth has to be to send it to a device that can transmit it to the Bitocoin mempool.

An implementation via Bluetooth with a project like Locha, would be interesting.

Just in case, Locha Mesh is a Venezuelan project that seeks to create a network to transmit Bitcoin transactions via wireless to be transmitted to the Bitcoin mempool later.

The twitter of the project: https://twitter.com/locha_io?lang=en

So bottomline, it is possible as it has already been done by several platforms. But they have some certain restrictions. We are already in the digital age so such transaction like this is very possible but we need to be alert on possible drawbacks like the viruses that come with it.

Now I’m thinking about this one and will try to make research about it. Though I heard that some of the new project already have this one but I have no idea about it. Internet is badly needed if you are transacting in cryptoworld and having an option like bluetooth to send crypto is a good one, but maybe it didn’t work well since very few project offer a system like this.

A Bluetooth device using radio waves to send signals to the receiver and that makes it complicated i think i send a lot of topics about this with Sending bitcoin through radio waves.

I think this is possible and you could send on the internet and find a similar topic or project.

Anything is possible nowadays.In fact, there are no barriers to creating software with which you can transfer bitcoins.Simply if you take into account the fact that for the transfer of bitcoins you need in any case an Internet connection, then most likely there is no need for such a service.

for now it cannot do transactions via bluetooth, maybe in the future can do a transaction like that, but for bluetooth it seems outdated, even for now Bluetooth has begun to be abandoned, people prefer SHAREit because it has a high transfer speed.

This is the first time I am hearing about it and wondering the possibility of it.
Sending Bitcoin through Bluetooth is more like sending Bitcoin without Internet or offline.
With few research done, only a few have tried this with Airbitz. It is not popularly lately which shows that it is not fully possible. Would really love to know how it is done though.

Sure but the problem with sending bitcoins over bluetooth connection is that the network can easily be tempered with and bring about loss of funds. I have witnessed several situations where hackers used bluetooth connections in stealing people's data. I believe the use of QR Codes is enough and secured, let's stick with that folks.

It's not save if connection using bluetooth , Bluetooth and radio frequencies are very different.
and also the distance of the Bluetooth connection can not be far from the distance of one user to another user.

How come you can send you bitcoin using bluetooth? there are not space using internet access where for sending bitcoin we need internet with good speed, maybe when sending bitcoin available using Bluethooth how about safety and need to back up with google authicator or not, will give chance for hacker easy to get many bitcoin if later bluetooth can send bitcoin or altcoin?

Yes it is although it sounds like old fashioned but who knows this thing could be our last resort if the internet goes down like there's natural calamity happened and there is no electricity that could run internet and satellites had also been down. Yeah? Just take some risk for virus tho. 😅

The virus will develop in such a way because there are many security holes in the Bluetooth protocol and can activate and send all available balances without us knowing, just by developing tricks of certain applications, all of them will be accessible and include seed and 2fa. If there are developers who can make it happen, the volume of usage will be far from expectations.

One implementation I'm thinking for such idea, if you have heard of HTCs phone running a full node, then transfers using bluetooth, consider having a wallet application for mobile phones, could relay transaction details to a full node, whether be it an actual computer with bluetooth card, or a phone running a full node, could make it easier to transfer Bitcoins even when you're offline. Like hotspots for you to conduct transactions, though security might be a concern from different weakpoints in the device, and the encryption of transfer of data.

you can also send bitcoin using smoke... it is just zeros and ones after all and a short smoke indicates zero whereas a longer one indicates one.
the "smoke", Bluetooth, satellite, radio waves, even SMS, ... and using the internet are just methods of communicating the same data between peers. obviously they all have their limitations and features. for example most of  the alternative ways have shorter range and sometimes rely on another centralized service and so far internet remains the only viable option because it is global and fast while you an transfer any big size of data such as the entire blockchain without any problems.

Bluetooth can't cover a large area, so I think it will be difficult. and I also don't think it will be possible because they have differences in the network, so far I have been comfortable with the blokchain network instead of having to use a local mobile network because it is not good enough in my opinion.

Bluetooth and infra-red covers a short distance and slow it would very possible to send bitcoin between two devices however the two transfer protocols are old fashioned and obsolete, technology has improved has gone beyond using those means  by having a better alternative and faster means of transferring bitcoin.

If you really want it complete decentralized then I think you should ask about how to transfer Bitcoin in a local wifi network of a device.?

If that is possible then the adoption of bitcoin will be a huge hit as shop owners can easily use it.

sending or receiving bitcoin via bluetooth or radio waves I think this will be a solution for people when experiencing difficulties when the government is centrally revoking internet resources, but for now if we see everyone still using the internet to trade bitcoin because it uses the internet network surely will be easier than via Bluetooth, satellite and radio waves.

I think that the transfer of Bitcoins via Bluetooth is not very convenient and may not even be completely safe. It is much better to use a QR code scanner. It is very convenient and much safer. And in general, the transfer of cryptocurrency is better carried out through a good stable Internet connection in order to avoid any failure.

It maybe possible but not reliable enough only small interference between two devices can make the transaction failed and if Im not mistaken bluetooth connection can only reached short distances like 10-15 meters so theres no important advantage of using this connection in any bitcoin transaction I think. 

You still will need internet connection to send this transaction on blockchain. But if you want to just use device id instead of wallet address you can just use NFC/QR/BT/etc

According to the post below, its possible to use this near-field communication which is almost like bluetooth.

I wouldn't use this to send BTC unless there is no other way though. Internet can easily be accessed today because every corners today has signs of free wi-fi.




True. You are making transaction through mobile device so why not instead QR code, that's easy.

No, this might be possible but there are more risks than usual. Bluetooth can be used without internet, but the thing is, there are more other users who can see/receive/send or simply interact with the transaction as long as they are in a certain range of it.

I think it will be better if it can be done via WiFi instead of Bluetooth because Bluetooth is like a pretty shitty network and very week in that sense and ofcourse I would love if that is going to happen but I would prefer wifi over Bluetooth network.

It is indeed possible but there is alot of restriction when it comes to this. Bluetooth communication range is limited depending on the class you have, you can reach a max 100m/328ft as per google said on class 1 bluetooth devices which means you can't send bitcoin from very far way not even maybe another province from you. Plus bluetooths security,  the tech behind bluetooth is we can say a bit old even if its getting updated it just basicaly not a fit to be use as a medium in bitcoin transactions.

That would be the main restriction if we will try to imagine having transactions using Bluetooth. It's range is limited and due to this reason, it will be impossible to make transactions to one another from different location or overseas.

it will never happen, Bluetooth will not be able to help you use the blockchain and connect to the entire market. We need to have internet network for blockchain to work. Also the internet helps to link the whole world together, and bluetooth can't do it. This is a good idea but I am sure it will never come true

Anything is possible as long as there is some sort of means for data to propagate. However, I don't think that bluetooth is necessarily a very safe channel or an appropriate one for that matter for transaction data to be sent.

You need to actively be paired with a bluetooth device in order to transfer data, as opposed to something like NFC which is open ended.

The closest thing to bluetooth is the NFC tech that we've seen. We've also seen efforts to make bitcoin accessible through SMS networks and stuff like that. But honestly, with the internet's progression, it isn't really cause for worry.

Im not that computer geek but I think this is possible but close to being not possible. When we can store btc through offline method then we could possibly transfer btc in an offline method with the help of bluetooth. Im not sure about this but surely computer engineers and sciences have something to say about this. This will be a continuous progress of btc then.

If technology develops in the future, I think this might be feasible and used. But I'm worried about the security of blockchain as well as bitcoin because the shared bluetooth can be stolen and hackers easily attack. And for the developing world, the internet is the most important thing for us, and I think that blockchain as well as bitcoin just need the development of the internet is enough, everyone will have access to it

It might be good, honestly, but do we think bluetooth technology is really effucient these days? Because allot of issues concerning bluetooth connecrion are there, to transfer information, you need to pair it first which I find the difficulty in sending money. People might turn out to go back to traditional fiats if that happens so, I better consider retaining the ways we have right now and focus on making the transaction speed even faster.

Good ideas when sending bitcoin using bletooth and keep upgrade their system of bitcoin become most valuable at the future where many people become easy for sending and receiving bitcoin in their wallet, without have internet they can make transaction with bitcoin very easy and want to accepted bitcoin with many countries at the future.

Bitcoin is encrypted with the use of hashing and a lot of algorithms to make sure all of the information and address of the transaction is secured.  Most of the time we are using websites or application to make sure the operation will be secured and no intereaction and to make it safe, If Bluetooth transaction using bitcoin will be created it is more convenient to send to the people near you. Still, it is hard to communicate with the other party because of the limited range of Bluetooth but if they improve this signal is better. This kind of actions very prone to hackers because they can use the internet and jamming the connection to get or receive the money and identify the transaction.

As far as I know, only IOTA has used Bluetooth technology.
Maybe you have to do R&D before actually being developed using Bluetooth. Because so far the development of IOTA has also experienced a significant decline.
So it's better to keep using the existing system because bitcoin has also been running for a long time and still tops the top position of all existing coins.

I agree it will be more hard to transfer money if we will used bluetooth. In fact Bluetooth is not that useful nowadays. Because it needs to pair first and sometimes its not easy to find the other device. 

Honeslty, sending bitcoin using bluetooth can be used because i heard legder NANO X wallet are been able to have a bluetooth support, which you can now send and pair with your phone, so you could send cryptocurrency.
It's true that this kind connectivity are prone to hackers because they can easily connect with you, but you can still see which address that you have send your crypto.

Please can you further explain to me how this can be made possible. This is not helping me understand why you think it might be possible to send bitcoin over Bluetooth. Further explanations might help people like me appreciate what you are trying to put across.

Is this for real? I've been using cryptocurrency all these years but I dont have any idea regarding to this topic about sending money through bluetooth. I think that idea is cool because sending through bluetooth is very easy and yes you are right it is really prone to hackers and bad people coz they can stole your coins but the good thing here you can see which user does the address belongs to  and in that way you can easily find who stole your coins.

Interesting. This could've become a big hit if many people would've noticed it back then. Of course, Bluetooth is not safe by design. But it could be used as a last resort for P2P transactions when the Internet connection is down or even on emergency situations. Maybe someday, another dev team will revive this project to make bluetooth-based Bitcoin transactions more practical for everyday people. For this to become the norm of P2P Bitcoin payments, the Bluetooth protocol needs to implement some kind of encryption for security. With a new version/specification of the Bluetooth protocol, we might see this become a reality sometime in the future.

Until then, only NFC and QR-code payments will be way to go in crypto land. They're still convenient for everyday use, but not as versatile as Bluetooth is. With a satellite infrastructure and even radio waves for Bitcoin transfers, this may be all we need to send frictionless payments in a P2P manner. :)



Awesome. Never thought this would be possible with the Airbitz wallet. It's disappointing to see the Bluetooth feature available only for Apple devices as most people use Android today. Still though, Bluetooth is not encrypted by design which leaves it open against external attacks. Without necessary precautions, you could end up losing all your crypto balance in a "blink of an eye". With other alternatives like NFC and QR-codes, bluetooth transfers might not be necessary after all. ;)

Yeah I agree with some comments.
It's a bit old and slow.
There is a better kind of connection now between two smartphones and this is being done by most application now.
Let us use Xender as an example.
You will be using the WIFI connection to send the file.
The other phone will be opening its WIFI hotspot in his device and the other one will connect.
The good thing is the security because you can input a password thru WPA2 PSK. It is more faster.

This might be an old issue but it completely sounds new to me. I was assuming that for a transaction on the network to be completed, it has to be broadcasted there, which means there has to be an online connection reached.

But I guess the downside of this is that when doing a P2P transaction using a bluetooth connection, not only is it not safe it will have to be like face-to-face. It also keeps the anonymity away from such transactions.

I don't think it is great, some mobile devices have a slow Bluetooth connection which is hard to transfer files. I think NFC is way better than Bluetooth to use nowadays when there is no wifi connection. Sending or paying bitcoin using NFC I think is already existing.

I don't use Bluetooth for long now. I try NFC sometimes but not regularly. I prefer some mobile apps in file transfer. But if thru wallet to wallet sending of bitcoin then NFC is a good option, or let's stick to QR code scanning. If there will be something that will develop a no Internet needed transferring from one device to another like an offline wallet. It will be a great development.

It's not actually powered by bluetooth but it's just most phones today has still the bluetooth function.

But that doesn't mean that it's going to be reliable when someone finally creates a way to transfer bitcoin through it.

But thinking of the technology offered by the ledget nano x, they are connecting the hardware itself to the cellphone so you don't need to have a wired connectivity to your phone, but if you are transacting and sending actual bitcoins or cryptocurrency, your medium there is internet or WIFI. Just to make it clear, you aren't sending bitcoins over bluetooth, you are just connecting the ledger to your mobile device which turns out to have a very different concept. Still, Wireless transactions over internet is what making it possible to send cryptocurrency and broadcast the transaction to the network.

it would be better if we could use everything from our Handphones, it really makes it easy for us to trade

I recently just heard about this that you can actually send bitcoin through Bluetooth connection, but i think you can only send a bitcoin via bluetooth in only a limited distance because every bluetooth device can only make an exchange data for only a short distances using short wavelength UHF radio waves.

Possible I think, and it may be a little thing for those honorable persons to develop it. The thing is that bluetooth doesn't have a wide range span of accessibility thus, it would be good for around of people that bluetooth can reach. However, transactions usually happened across the globe so, may be developing bluetooth features isn't as much as necessary, imo for now.

It is not possible to bridge Bluetooth protocols especially ip addressing in bluetooth connection because it doesn't have IP addressing when transaction will be made on bluetooth, so it is very imposible to get and do transaction over it. So the bitcoin is very hard to made a transaction due to imposible ip addressing of it. TCP and IP are only applicable for internet connections in laptop and personal computers because that will be the one who will network in order to get the ip and tcp protocol of each events. If it will be happen a transaction through Bluetooth it takes some years and time to configure it by the developers and programmers as well.

Actually sending bitcoin or any altcoin through bluetooth is possible because it is a peer to peer connection. And if this will possibly happen in the future it will much more easier than sending through internet. If this will happen it is a good idea most especially if you dont have an internet connection to send bitcoins or any altcoins.

It seems to me that transferring any data using Bluetooth is very dangerous, because there will be risks to lose your money.  Of course, it would be nice to use Bluetooth to transfer cryptocurrencies when paying for these goods in the store, because in reality not all Internet services are available.  In addition, my country has such retail outlets where there is still very weak communication between mobile operators, since the room is located in basements or in other places that are difficult to access for the signal.  In this case, bluetooth would provide very good opportunities for paying for goods using cryptocurrency.

Not good way for sending bitcoin using bluetooth because only can make transaction with close mobile phone device, how ever bitcoin is digital currency payment transaction where could send for other country with have far way each other, if keep using bluetooth as way for sending make bitcoin become down as legal currency payment transaction.

I agree just using radio waves to send bitcoin, in my opinion is very risky since we are sending bitcoin something could easily go wrong in the process and potentially you could easily lose your bitcoin while sending it because comparing it to internet there could easily interfere in the process. But this kind of project is already possible or already done and I already see this topic on the internet for a long time you could check this link:

https://www.coindesk.com/bitcoin-box-can-process-payments-web-connection

Indeed, such a topic is no longer new and indeed it is gaining momentum in terms of negotiability, as there are users who would like to have the Bluetooth function for transferring cryptocurrency.  Already today there is a new version of the hardware wallet for storing the cryptocurrency Ledger Nano X  which has the highest level of security and at the same time provides bluetooth functions.  I think that the developers of such a product really took care of security and users would not have to worry about the safety of their keys and cryptocurrency funds.
I also liked the information that you provided on this link.  The Bitcoin boxing device will really be useful for paying with cryptocurrency without an Internet connection, when the infrastructure for using Bitcoin as a means of payment will expand well.  In any case, I hope so, since such leading companies of the world as Apple pay enough attention to products from the cryptocurrency market.

It won't work. With satellite, you connect to the blockchain and not just the other device. You need contact with the blockchain t transmits the broadcast. Bluetooth will only allow you to connect to devices within its limited range. Likewise, wifi won't work either since you need a connection to the blockchain.

thats a cool idea if its possible but why not  ? before we only use infared then upgraded to bluetooth and now wifi but wifi mainly uses an internet  . whats good with infared and bluetooth is that they both offline  and being offline is the one that we want for cryptos so that we can use it anywhere but it will only good for sending and recieving   , we still need internet to access trading sites and other services online  .  for now i dont hear any of this that already worked , its only a concept although  .

Do you never give money to your friends? It could be convenient when the person is near you. If you need $10 you can ask your friend to give you $10 and you give him the equivalent in Bitcoin. "Hey dude, give me $10 if you can, I give you 0.001BTC in exchange, turn on your BT connection".

Not everyone has an internet connection on the phone. Internet here, internet there, we're always connected to the internet in a way or another, always living near a connected device. At home, at work, at the train station, at Mc Donald, everywhere, even in the toilets. Sometimes it's boring.  

No need to use Bitcoin only to send money via the internet to someone living far away from you. Bluetooth is energy-saving also, it even uses less than Zwave, Zigbee protocol. Yes, the distance between Wifi and Bluetooth isn't the same but we don't care, you don't talk to a friend at 100 meters from you "Hey dude! How are U? Do you hear me? I send you the 10$ from last week!"

I haven't heard this could be possible and sending transactions using Bluetooth is somewhat done at local network, without the presence of blockchain. The reality is that if we're sending bitcoin all over the world or at any location, that could be done successfully through an internet connection so it could be transact using blockchain technology.
Bluetooth is somehow a perspective and impossible for this time as bitcoin required to pass through different nodes.

IMO, this will be just the alternative for the technology we already have right now which is the wireless fidelity, because transacting ovee bluetooth is like tracing back to traditional and old way of communication and trasfer. With wifi, we are capable of transacting at greater speed  and with more secured security features. In addition, if we are paying like a small amount of transaction and we need topair and locate one another, I think it isn't that much convenient.

But sending bitcoin through a bluetooth is much uncertain and unsafe because maybe your data will lose when the connections suddenly interrupted. There are barriers that can serves us a hinders that can slow the process of transferring data. Maybe the advantage of using bluetooth is that it doesn't require the users an internet but like what i've said it is slower. But if it uses internet, the transfer will be good and useful for the bitcoin since it talks about money.

It may be possible and convenient for local purchases, but it is safe? we know that there are malware or phishing attacks everywhere and we didn't know that we attach to another device or technology using bluetooth and that device is possible for this viruses. so using bluetooth is improve and safer enough to deliver our btc transaction to another? maybe not, because this idea is too old and no one has yet discovered it.

Although the statement of sending bitcoin via Bluetooth has been a long time but I have just heard it now, is it safe because using a Bluetooth connection is limited and besides if the connection is lost, is the transaction successful or failed?
because what i know about transferring something using bluetooth there must be a problem with the connection being lost whether it does not endanger both parties, it looks like I have to study it or find out the truth, because that way will help when the internet connection is not good or not supportive.

I think its possible but i do still have the doubts when we do talk about security.I read up something about interference https://www.goldtouch.com/stop-bluetooth-interference-messing-devices/ .Its just normal for us to think that this add up wont be necessary yet internet is everywhere but seeing bitcoin transfer can be done by just having bluetooth then that would be great.

Mesh networks work through IR and even Bluetooth, so yeah, as long as you can transmit data wirelessly (which is basically all the methods you mentioned), there's always going to be a way to send data, hence, send Bitcoin. As long as just one of those peers within the mesh is connected to the Bitcoin network, or able to send a tx to someone to broadcast it, it's all good.

Strange as it may seem, some places may be able to connect to satellite easier than to a cable or phone line (how we conventionally connect to internet I mean).

It gets the job done in scenarios where regular internet isn't readily available, but it's definitely not safer than transacting regularly.

In the end, it all comes down to security tradeoffs when you want to get something done alternatively. Lightning Network is the same. You don't enjoy the top notch security of the main network, but you get the convenience of being able to send Bitcoin instantly and near free. As long as the amounts concerned are low, the security tradeoffs don't come even close to the convenience Lightning provides you.

Nowadays it's impossible to randomly connect to a smartphone without having to manually approve the incoming connection request. I remember back when I had a Samsung D500 I randomly connected to people's phones just for fun.  :D I'm glad things are different on that front now.

So the bottom line, we can send crypto through Bluetooth. It is so cool and sounds amazing :o. However, I'm getting a little bit skeptical with regards to speed of data transfer. I mean, most of us already quit using Bluetooth because faster data sharing apps like ShareIt and etc. are already invented.

If sending bitcoin through Bluetooth takes a half hour or longer than that then I'm pass. I still stick it our usual way ;D.

I think its doable. By simply sending a code to the other device maybe they can make some programming enhancements and innovations. But certain precautions should also be noted to it as it can be prone to some scams as well. We must be careful also in using bluetooth device in public areas. There must be additional security measures to protect us from scammers.

Building a technology that could support this is not a farfetched idea. So far we have made projects and programs otherwise thought to be impossible in the early times. I guess transferring bitcoin through bluetooth poses greater benefits than greater threats. But this still need more research, hoping there is a development team that could review this and conduct an in-depth study regarding bluetooth transfer to see if this will be a viable option.

but are we really need bluetooth connection for bitcoin transaction?
i think bluetooth is old technology, we can use internet connection or maybe NFC.

We still don't know if that may be possible, but it would be great. Bluetooth does not need internet to pass files, because even when I need to pass a file and we have no internet connection, we always do it through Bluetooth. So it would be a breakthrough and a great opportunity to transfer bitcoin without the need for internet. I hope this technology is given.

It's okay and it is surely possible actually considering you can transfer any sort of files there. I've read that Airblitz has this feature of sending Bitcoin over Bluetooth.
It's quite unique, but I am kinda thinking of things like its security, especially if pair-keys are kinda hackable so that it will get sent to the hacker instead of the real receiver.

If we send bitcoin over Bluetooth without net connection then it is
not possible to mine it. so without confirmation it is not possible to
send.

but it is possible if miner has a built in bluetooth option with a vast
coverage and it is useable within a short area like in a
supershop/departmental store.

after the transfer, you will also need to go online to confirm the transaction
it's also possible that the sender will cancel the transaction or remove the coin before you confirm it
in my opinion, even it is possible it will be complicated and not safe

I think sending bitcoin using a Bluetooth is the same as sending bitcoin using QR codes because you can only make transactions in a small distances, but sending bitcoin over bluetooth is very prone to hackers because they can easily connect with your transaction, so it is still better to make transactions in crypto by QR codes because no one can actually join to your transaction.

That's really an amazing idea to just send bitcoin using Bluetooth or any kind of antenna system or even using satellites. I mean in that case we don't even need the internet to do that, it will be more easier and so secure and safe. I don't know if that's gonna be feasible or not, but if there's any connexion between Bluetooth networks and blockchain then it can happen.

You really described a very good sense, where you can make cryptocurrency transactions using qr code.  But the fact is that this idea can be implemented, for example, with fixed payments, which can be carried out, for example, in public transport, where using a mobile device and a scanner you can pay for a ticket using cryptocurrency.  But with regard to the use of bluetooth, the situation is really complicated, Although it can be implemented for payments, for example, in a cafe.

Considering that Bluetooth is not a safe protocol for sending sensitive information, we're left with QR codes and NFC tags as transfer mediums for Bitcoin transactions. While NFC is a good option for programming Bitcoin transfers, it works in a very close proximity. On the other hand, QR codes work nearly the same way as NFC tags but they cannot be programmed or modified to our heart's content. Bluetooth could've been a great alternative for sending Bitcoin locally at relatively long distances. An encrypted Bluetooth protocol specification would be ideal for sending Bitcoin off-chain to another device quickly and easily. This would work wonders for basic devices that don't have NFC capabilities or even the ability to scan QR codes (like featurephones).

At least, the idea is there. Maybe sometime in the future someone would become interested in reviving this for the benefit of Bitcoin? It's good to have various ways of sending/receiving Bitcoin for true censorship resistance. We now have satellites, mesh networks for offline transactions, and even ham radio waves for sending/receiving Bitcoin. I think this is more than enough for interacting with Bitcoin in a decentralized manner. Just my thoughts ;D

Bluetooth pairing is somewhat old tech when it comes to security standards IMO. It's easy to intercept and easy to hijack. There were quite a few bluetooth-capable wallet that was introduced in the past IIRC, although these projects didn't last given the susceptibility of the incorporated tech to hacks and hijacks. Even with today's bluetooth 5.0, security still isn't a main focus and they really tweaked more on energy utilization and data transfers.

I'd be quite surprised to see whether a Bluetooth-enabled crypto wallet would be recommended by developers. It might be feasible and practical on instant transfers though again, the security is quite scary.

Agree, in my opinion it is already possible since there are already a lot of articles about this but I don't this is recommended since we are using radio waves in Bluetooth if it is a complete version that doesn't have errors I think it is going to work fine. But maybe we could encounter an error because Bluetooth signal can interfere not easily but compare to the internet or other connection for me it is more exposed and maybe you could lose your bitcoin with this.

On point. For me as long as it is not yet fully created or recommended we should just stay away in this kind of project since it is still in the process of development.

You correct . Bluetooth has more disadvantages than radio waves when sending bitcoin.
I rather admire transactions that use radio waves as explained here.
https://twitter.com/nvk/status/1095340008293130242?s=19

Bluetooth as a transaction medium could be useful to grow cryptocurrency adoption because many parts of the world do not have internet access. Cryptocurrencies pretty much require an internet connection in order to use them, so I am thinking that bluetooth can be used as a mesh network for relaying transactions.

Why not, anyway? We already have bluetooth speakers (audio stream relay), bluetooth printers (parallel port relay), webcams which relay video streams, GPS devices (location data) and keyboards. The point I'm trying to make is that all of these devices are sending different types of data to the hardware which does vastly different things. So it makes sense that we use bluetooth wallets or some other yet-to-exist cryptocurrency hardware to relay transactions.

There are off-the-grid mesh messaging apps already around that use bluetooth for this but work best in population-dense areas. A bitcoin relay would need to be more long ranged than this.

All someone would have to do is create a device driver that interacts with a hardware wallet. So bluetooth transactions would in theory go well with hardware wallets.

So all somebody in a rural area with limited internet connectivity would need to use cryptocurrency is a hardware wallet and a smartphone (for the use of bluetooth only), the transaction would be relayed across other phones until it reaches an endpoint that has internet connectivity to transmit the transaction normally. It has the potential of replacing credit cards with the additional advantage that a stolen hardware wallet is useless without the private key.

Granted, all of this requires the Lightning Network be finished first before we can send bitcoins in this fashion.

Maybe it is already possible these days but still it is not recommended due to the safety that is not yet assured when using such kind of medium for transactions. I don't have any idea yet on how you can do it with mobile phones but I will surely start studying how to use it so that I can get convenience someday. We all know how important the internet is for transactions but if ever the system for bluetooth transactions will be fixed, it would be a great help for offline transactions.

I don't think this is possible as of now for bitcoin as it really needs the internet, but maybe another coin could do this and rely on bluetooth so we will just have to wait for the scientists to discover it. It would be efficient as long as it can not be compromised.

So it's not possible to do this with bitcoin yet? I still hope that this technology will be developed and transactions will occur instantly.

Bluetooth is used to send/receive files.Do you think that parts of bitcoin can be transformed into a file?
This is a pretty weird idea,if you ask me.How can sending via bluetooth make the bitcoin transactions faster and more convenient?The receiving user will have to wait for confirmations.
This is complicated stuff,I'm not an expert,but I don't see any benefit in such innovation.

In the new age we are into right now is all about having fast things, fast cars, fast bikes, fast, computers, fast internet connection, and so many more to mention. I guess it is possible that way but using Bluetooth is too old fashioned, also the distance of pairing two devices is very limited compare if you're going to use Wi-Fi.

However, the risk by using Bluetooth or Wi-Fi, especially when it's public, is very high, it could always be penetrated by hackers, anytime.

It is not actually possible.
As we all know, Bluetooth is not safe if it will be used in this technology, there is a lot of people that can be detected in a certain area if this will apply to blockchain. Also, there is only a certain range of 10 meters or 33 feet depends on its Class. It won't even reach overseas, that's why it is impossible.

Bluetooth is too limited in range. I've been looking at LoRa, and that looks as if it might be the way forward.

You have a point. This is why bluetooth devices only work when they are close by. Which means bluetooth won't work with my relay idea.

I'm not sure if any computer or phone ships with a LoRa chip in them. Perhaps ad-hoc W-Fi or at least a wireless LAN without routers could be a solution that developers can work on immediately? (If they were to start today.)

security when doing transactions using bluetooth is something that is very doubtful because the security of Bluetooth is vulnerable
it can even be very easy to do snifing on bluetooth so that your funds will not be safe
but doing bitcoin transactions I think is very possible

To be honest, I did not like this idea because it is too risky to send Bitcoin or cryptocurrencies in general over bluetooth also the viruses are widespread in this technology. The security is one of the important factors that attract the users of crypto , without it your wallet would not be safe anymore.
Plus, it is important to turn the  idea into reality but without creativity there is no usefull technology to community especially in Blockchain domain.

Why would you choose Bluetooth if you can transfer it using the hotspot network of your phone?
Wi-Fi technology is always there even streets in your hood already have public Wi-Fi. It's better to send your Bitcoins through it than using Bluetooth, we all know that BT has a very slow speed transfer.

IMO, BT is also not safe, you must pair to the other device and both of you have access already on his/her files especially bitcoin so this will not guarantee your security of the transaction. Also, there are many keyloggers that might affect your device to hijack or access your BTC.

If bitcoin transactions were transmitted through public WiFis, where there are known hackers and other dark figures eavesdropping on it, then the whole thing had better be encrypted with TLS.

The Wi-Fi hotspots themselves should be fast enough to handle all those transactions since they aren't being sent over the internet on that connection, so the speed of the network device itself would be the limit. Which would be very high for most modern network hardware.

Probably there is some risk while we're talking about the virus and stuffs but here you're transferring bitcoin and not data, so I don't think that there's a risk while we're talking about transferring bitcoin using Bluetooth and I think it's a really good thing because here, we're not using the internet to do it, we're only using signals which it's really amazing for people to buy stuff online while they don't have internet at any place.

Some months ago i read about broadcast transactions with radio transmissions, so, if this is possible, maybe it could be addapted to broadcast the transactions via Bluetooth...

I will leave the source here: https://blockonomi.com/bitcoin-transactions-radio/

It might be possible but it has a lot of disadvantages too. Using Bluetooth so send money is not a good idea for me because there can be a situation in which your money can be lost. What if someone connected to you already knowing that you are thinking you are sending that money on a certain person you want to but it didn't happen. I think QR codes are still the best for sending money and also addresses. I can also say that maybe we can send money through our mobile number if we have wallet mobile application and that wallet is connected to your number. Sending money using Bluetooth is not safe for us, that's what I think.

This would work more for "off-chain" (offline) transactions, instead of securing and maintaining the Bitcoin blockchain with it. Individuals could simply send unsigned transactions via Bluetooth to sign them later on their mobile devices for security. There are many ways to prevent the loss or theft of crypto funds, even if the user is relying on an unencrypted protocol like Bluetooth. While developers haven't came up with something like this, they could implement it in the future if there's enough demand from people in the mainstream world. There might be other important things to focus right now, than sending/receiving transaction using Bluetooth technology.

As long as QR codes and NFC tags exist, anyone can send offline transactions without the need for Bluetooth. The latter is something optional than necessary for the adoption of Bitcoin within the mainstream world. If something like this becomes a reality in the future, then expect Bluetooth transactions to become viral in crypto land. Above all else, the Bluetooth protocol may need to be redesigned in order to encrypt transfers from one device to another. This will pave the way towards mainstream Bitcoin transactions using Bluetooth technology if the need arises.

Nonetheless, Bitcoin has performed flawlessly (sort of) with various implementations for sending/receiving transactions in an "off-chain" manner. With satellites, mesh network antennas, and even Ham Radio waves, you get everything you need to perform transactions "off-grid" in any undesired situation (like natural disasters). Bluetooth is just "the tip of the iceberg", in my own opinion :)

It's not impossible sending Bitcoin over Bluetooth,
But remember, Bluetooth is the most insecure medium For data transfer.
If we want to send Bitcoin via Bluetooth it will be at high risk, there is a high chance of hacking and network interruption.
I think using QR code is ok, it is secured and easy to use.

It is possible but somewhat risky, because remembering the basic principles of a transaction in BTC you need a blockchain to get a transaction to operate at a certain time. On the other hand, bluetooth is a protocol that is generally used for multimedia functions, it could be possible if the transaction was made via bluetooth but it would be more vulnerable to being stolen, since the use of the blockchain would be ruled out, it would be useful when connection is not available , but I don't know if the risk is worth it, and merging both really wouldn't know how to respond.

I think it's impossible to transfer bitcoin to Bluetooth because because we can use Bluetooth even no Internet. And it's been so risky because once you open your Bluetooth and connect to reciever it's been more Bluetooth open so it's not safe. Much better to online wallet than Bluetooth.

Changing ways of transacting over the bitcoin network do really is essential for the development of the market because of finding alternatives to our native option of transacting over the internet. But imagine, the network that connects the whole world is only the internet because it is directly connected to the transatlantic cables that is shared over the seabed of the world. If we are to rely our transaction over bluetooth, it simply means one thing, which is to make a transaction over a short distance and still needs internet in order to broadcast the transaction. The only way I see bluetooth to be beneficial is what ledger nano S does, which is to connect the drive to mobile phones which makes it easier.

I do not think so he has asked about the comparison, definitely internet is the best mean of making transactions. I would say that looking at all the technological advancements and the increase in there number we will achieve a time when we will be able to send Bitcoin from anywhere to the whole world without electricity and internet. If taking in consideration that time, it is possible to send Bitcoin over Bluetooth.

There's no harm in sending money over bluetooth. However, its time consuming and even might need a most advanced technology which can convert Bluetooth into sending cryptocurrencies on a local network. And yes there are rooms which are located at basements with insufficient internet connectivity.

But, there will be a day where we all might be able to send cryptocurrencies using bluetooth from anywhere and any corner of the world. And people will be able to send and receive money without any network errors. We still need a good network connection to handle and deal with cryptocurrencies. There are places where we don't even get an access to internet connection so in that case bluetooth could help us for cryptocurrency transactions.

It’s not a matter of good and bad. It’s a matter of the situation. If you are in a situation where you are not having good connection for your transactions then you need to shift over on bluetooth transaction and if you are having a sufficient connection then go for it. You have a limited access when you perform transaction over bluetooth.

But, if you need to do a transaction globally then you need to have a proper Internet connectivity. Sending bitcoins over Bluetooth might restrict you on the distance between the transaction as you need to be connected over the Bluetooth in order to transact your currencies.

There would be some platforms which might be developed soon which can enable Bluetooth transactions and it would really make an boost in the transactions amongst the peoples who live nearby and want to transact with the cryptocurrencies. It might also be accepted in local businesses as receiving bitcoins would get much easier for local store operators.

Bitcoin using Bluetooth? In short, we can use to connect in a small area without any use of internet? Maybe, it is something that is hard to explain. And I think it would not happen easily. Because we need internet so that all people may access to other. Since, bitcoin is decentralized. It needs to be connected with internet so that the btc will be added to the people and recognise by people.
A big dream for me to have that, but it remains a dream until it proven.

Sending bitcoin via is not possible since as we know there are lots of machines connected via internet, bluetooth can only handles only limited connections of devices , while bitcoin needs an entire network because of connections of lots of miners doing the work, bluetooth
can connect in a short distance, also data that going to send is different and should be connected via internet while bluetooth is isolated, its not going to work

I've just read the article and seems sending Bitcoin through Bluetooth is possible however, in order to perform this kind of transaction there will be a help of a certain device which is "Bitcoin Box". Bitcoin box is developed by Jan Vornberger which a user can perform an offline transaction through the use of Bluetooth and NFC. But though the use of Bluetooth without help of any device, I guess it is not possible for now.

To be honest, I just heard this, of course it all has to have a strong measuring point in terms of trying to transact via Bluetooth, because this will be a risk for everyone and of course they will lose their bitcoin, with no security that is strong enough in that case, if that is done it might be very good going forward, so that more and more people are interested in Bitcoin ..


With so much technology being added or created will expand the technology that bitcoin has in the future, and everyone will certainly not underestimate bitcoin in the future.

As per my knowledge, it is not possible to send BTC via Bluetooth. Your transaction needed to be confirmed, but if there is no internet the transaction will not be confirmed by the blockchain network.

And if it is possible by using Bluetooth, then you will stuck on another problem that is the distance limit of Bluetooth.  using it one cannot send BTC in a long enough distance,

I'm not really an expert in technologies but I think it is possible so long as both devices are connected and both devices recognizes bitcoin however, bluetooth isn't being use often nowadays because sharing or transferring files from one device to another using bluetooth takes time depending on the size of the item you are transferring and not all devices are compatible like for example apple devices to android devices. On the other note, there are a lot of apps now that allow transfers in a faster manner than bluetooth and if we are to use the same technology for bitcoin, it be good since it’s fast but I think it is not secure if we do it that way, I still prefer the current technology used in making p2p transaction because it is secure.

According to my stupid experience, the bluetooth network is a wireless or wireless data communication technology that is useful as an exchange of data between several electronic devices, such as headsets, mobile fc, printers, routers, cameras and in fact, bluetooth cannot be used as a medium that connects the entire blockchain network , while bitcoin exists because of the internet,
Even though I have read several articles but I still find it difficult to understand how to send bitcoins via bluetooth.
please shering when there is a friend who knows how

I think this is very difficult to realize. actually I have read several articles like this a few months back where there said something similar like this.
but I think it is a bit difficult, the first reason is its limited range. As far as I know, the most distant Bluetooth range is only 100 meters and this is very inconvenient if you want to make long transactions.
the other reason might be troublesome for the bluetooth device itself because I think it's too heavy to send via this device
