Bitcoin Forum

May be some find the idea crazy but if it will be soon a revolution in computing like quantum computing and in neuroscience in 30 years could be very near.
The NSA supersystem in Utah has reserved for everybody on the Earth 100GB and this without quantum computing.
You need a mind scanner and enough space to upload it and live forever ... if the government doesn't delete you.  ??? ??? ???
So it will be needed a new blockchain based on Bitcoin(or an enhanced Namecoin with life/ namespace).
For ex Bob pays to reserve a space in the blockchain as life/bob for 50 years then 50 years his mind program will run 50 years after his death.
But his mind remains forever in the blockchain and can be reactivated any time if somebody renews life/bob and reactivates him.
 ;D ;D ;D
https://en.wikipedia.org/wiki/Mind_uploading
The idea is already in the wikipedia. My additional idea is only to upload it in a decentralized blockchain.
What do you mean ? To crazy idea ? Or a chance to live longer ?

What incentive do people have to host this blockchain?

Every 10 minutes would be created a block where the minds can be uploaded. Miners receive coins when they find a block.
The registration/renewal fees for life/ entries + the generated coins will be the incentive.
By the mind upload a certain amount of coins will be destroyed and this will secure the market demand for the mined coins.
By renewal of life/ entries only renewal fee will apply which will go to the miners.
The value for the lifecoins will be traded freely. Ask and demand will decide about the price.
The communication-protocol between the nodes will ensure that each uploaded-mine will have exactly one thread running inside of the network.
 ;D ;D ;D

are you high? static storage of brains, is like freezing it. you will exist forever, but you will have not thoughts and will therefor not live either.

you need a computer to calculate on the chemical reactions within the brain, not just a still picture of it.

this is crazy.

Correct. The brain has a short term memory, which will run on a dynamic memory and will be updated to the blockchain from time to time. (transferred to the long term memory)
Any other technical problems ?
 ;D ;D ;D

Will it be possible to be uploaded on the blockchain and do silly posts in bitcointalk?

Are you already in?

Yeah, maybe he's posting from the blockchaon and is just giving us a hint? Maybe the program existed really long time, we just haven't noticed? :o

What happens when the blockchain is forked?

Two of you maybe? Something like reverse scitsophrenia?

Multiple personality disorder? :D

It is not so much difference between genial and crazy.

This is a legitimate question because virtual life will differ from real life.
The scan of the cerebral cortex will be the main part of the uploaded mind. The brain centers for seeing and hearing will not be implemented but there will be standard modules to attach a webcam.
So disabled persons which have motor disabilities or disabilities in their audio-visual input will not be in disadvantage like in real life.
The activation of uploaded persons will need to make a complex check by start to see if they are in the main chain otherwise it will be not possible to avoid duplication.
However it could happen that hackers will crack some older mind backups to run them on their own network and they will work like kind of clones.
https://upload.wikimedia.org/wikipedia/en/9/93/Sixth_day.jpg

More like multiple body...

You would need multiple brains then.

Forked brains would lack the security and guaranty of the main chain. Virtual minds will have also some needs, to communicate for example, to hear and see the world.
Hacked and forked minds would be kept secretly(without communication with the outside world) in a kind of slavery just for exploiting them.
Their blockchain would be a slavery chain.
 :( :( :(

Slavery is evil even in the virtual life.

Ok, where I can download the client ?

http://dot-bit.org/forum/viewtopic.php?f=2&t=998&sid=366fffb241a208ff015654c85de512e1
Lifecoins will be built on the top of Namecoin so you need the Namecoin client and some coins also.
You could reserve already the namespace entry, the location for your virtual life with the Namecoin client 
(ex. life/bob)
for an unbelievable low price of 0.02 NMC.
When the technology will be ready(the mindscanner must be developed first) in 20-30 years then the Namecoin prices will be extremely high so it is better if you buy now a couple of thousand because the mind upload will cost about
100 NMC for the beginning and 10 NMC every year for standard hosting(but in 4 years the prices will be halved).
In the standard hosting the virtual mind capacities will be similar with the real one and for every new information stored something old must be deleted.

So far so good!
I only worry whether mindscanner will keep my brain intact while doing its work

you can check books on telepathy for this and you can do many things with this

They are recent breakthroughs in non-invasive brain imaging:
https://en.wikipedia.org/wiki/History_of_neuroimaging
Existing techniques like RMN scan are not altering the state of existing neural connections:
https://en.wikipedia.org/wiki/Magnetic_resonance_imaging
https://upload.wikimedia.org/wikipedia/commons/f/f1/BrainMRI3planes.gif
Slowly all parts of the puzzle could come together:
- brain-scanner
- quantum computer
- updated Namecoin technology to host and run uploaded minds

I just want to let everyone know, I don't really exist. My friend uploaded my mind to a blockchain, and I'm stuck here until someone works this out.

We will make a Turing test on you to be sure. You must be from an old beta version.
https://upload.wikimedia.org/wikipedia/commons/e/e4/Turing_Test_version_3.png
Uploaded minds in the final version will be indistinguishable from that of a human beings.

If my downloaded brain is indistinguishable from my old human brain, then how would a test be able to tell the difference? And I have access to the internet in here, so it's not like I'm frozen in time. But I don't really understand how this works.

Only which are uploaded with the reliable original brainscanner.
Those brainscanned with the older beta or with the cheep Chinese copy don't have all human brain capabilities.
Make a new upload and overwrite yourself then you will be indistinguishable from the original.  ;D ;D ;D
You can even choose premium features with 50% more virtual mind storage space and 50% higher speed and you will be like a hyperactive genius.

May be brainscan(basic technology requirement to the virtual life in a blockchain) is more closer than you think.
In the near future every American will have an implanted geolocator in his brain and his brain will be scanned periodically on suspected activities.
The current vice-president is admitting that this is already discussed.

Professor Stephen Hawking supports also this idea:

also by 2045 (assuming moore's law holds true) we will have enough computing power to simulate all the human minds on the planet..
of course moore's law probably won't hold true, but maybe quantum computers will still make this a possibility..

if you uploaded your mind into a computer, would you be a copy?
____________

Maybe we are just simulated now :

Nick Bostrom, Simulation Argument -- http://www.simulation-argument.com/simulation.html

states either 1 of the following is true

1. Mankind Destroys itself before we create simulations of reality
2. Mankind won't create simulations of reality (i think we will, MMORPGs and the way computer gaming etc is advancing is all heading torwards realism/immersive-ness[how u spell?])
3. We are almost certainly in a simulation (1 in a billion that we are not)

Not only may we be in a simulation (Matrix?), we would probably be simulated ourselves..


Maybe we are in a block chain now
The bigbang was the Genesis Block...
Maybe our minds are like CPUs, processing the blocks by collapsing wave functions through observation
______

Huntercoin / Chronokings could be the birth of decentralized Blockchain universes :D


________

Also note, when the blockchain is forked (someone's comment) you will roll back to the correct chain and experience deja vu..

My mind and yours will corrupt the blockchain of the future

Not sure I'd want my brain stored on a publicly accessible blockchain for 14 year old hackers to play around with in some weird simulated reality.

This is a really good question. Famous philosophers since longer time addressed this question.
Stanislaw Lem's fictive heroes are philosophizing about this question in some of his novels.
Would be the backup of your mind be yourself or just another identity ?
Could you make a copy of yourself to make all the work for you ?
https://en.wikipedia.org/wiki/Cyberiad  (https://en.wikipedia.org/wiki/Cyberiad)
Another book about this question would be:
https://en.wikipedia.org/wiki/The_Mind%27s_I (https://en.wikipedia.org/wiki/The_Mind%27s_I)
https://upload.wikimedia.org/wikipedia/en/d/d0/The_Mind%27s_I.jpg

This could be also a valid point of view.

Uploading a scan of your mind is not living forever, it is simply making an immortal copy of yourself :L

This is a philosophical topic. I would say it depends on the point of view and the implementation.
Your mind is in continuous change. You may think you are the same as you was 1 year ago but every atom of you was changed by your metabolism and your ideas, your brain content also changed.
So why are you the same person ? You may think that you are the same person because this change was continuous over the time and your mind and your body has been changed step by step.
It could be done the same with your uploaded brain. Your mind will be scanned and uploaded but not activated until your dead.
If you are feeling that your time is closer you put yourself in a machine which scans your brain and when specific brain regions are deactivated in the natural death process this function will be taken by your uploaded mind region and connected with your remaining active brain. So you will feel a continuous step by step continuation of your existence.
If others would see the same it is a different question.
You could even preserve your body by Cryonics with cryopreservation technique:
https://en.wikipedia.org/wiki/Cryonics (https://en.wikipedia.org/wiki/Cryonics)
https://upload.wikimedia.org/wikipedia/commons/9/93/Cryopreservation.jpg
Later when the technique is advanced then your mind could be reimplanted to your resurrected body.
The cryopreservation may be can preserve your body but not your neural connections and your mind so it could be helpful if your have a backup of your mind in an uncensored future Namecoin blockchain.(storing your mind on a central server could be cheaper but could be also altered)
Of course living in a blockchain could be more expensive than only to staying there and waiting to be reimplanted in your future cured body.
After a virtual living the reimplanting in your former body or another biological body could be done also step by step so that you have the feeling that your life was continuous and not interrupted by a coma.

Gotta admit it does look pretty cool :)

We are not the only one who are putting this questions.
The Immortality Institute is also working on a similar topic.

Why are you trying to connect bitcoins to the science of immortality and life exstension when there really is no correlation between the two. Besides who would maintain the network while everyone is living in the cloud.

If you want to sound "serious" or "scientific" or whatever stop posting wikipedia links ffs...

Luckily for you, Dank is on it.

As you saw in other thread Google has a D-Wave quantum computer and there is a 1 billion pound brain project also. The time when this futuristic vision will become reality is coming closer.
But would you trust Google to host by them your mind ? They would search and index all of his content.
Your mind will be secure only in the blockchain where your mind will be encrypted and will run decentralized.


In 2020 the world computation capacity will achieve that of a human brain and in 2040 of all human brains.

But what about creating an own virtual country  for virtual minds ?
Namecoinia ?
or Lifecoinistan ?
Or United Blockchain States of Virtual Lifes ?
Which one would you choose ?

It can be a federation of 3 states:
- the state of the premium uploaded minds
- the state of the standard minds
- the state of the beta minds
Own rules will be also needed.

The Ten Virtual Commandments could be:
- I am the Namecoin chain who is hosting your mind.
- You should have no other blockchain before me.
- You should not make a forked image of the blockchain.
- Newer use the blockchain in vane.
- Remember the miners and give them fee.
- You shall not delete data from other virtual minds running thread.
- You shall not feed your blockchain neighbor with false data.
- You shall not steal memory or hash power from other virtual minds.
- You shall not desire your blockchain neighbors memory.
- You shall not desire your  blockchain neighbors hash power.

It will be constructed a Lifecoin (which will run on Namecoin) payment system and virtual minds will use it to receive coins for their work or to pay to increase the hosting time(and their life) in the blockchain or to increase their memory or hash power. Lifecoins would be double virtual. They would be virtual even for the virtual minds.

LOL.. i like how you think Virtual-master

Problem thought, if our minds are stored in the block chain, they are going to be static? how can they change except once every 10 minutes... 1 Chronon = 10minutes.. maybe if we can reduce chronons (blocks) down to 0.00000000000000001 seconds ..
although.. as time is just a perception the virtual minds may experience time in the same way that we experience it (even if 10 minute block times).. so to us 10 years may have past but only 0.0000000000001 seconds have  past in the VirtualMindBlockChain....
so if we want them to interact with the real world the computer will have to be very fast... (it could remotely control a robot bio body?)

or do you just mean to store our virtual minds (so static is ok?)?

have you heard of Roses Law?
http://boingboing.net/2012/10/08/steve-jurvetson-on-roses-l.html

I don't make promises I am not able to keep whistle must invade neighbours mind and mine his virtual data
I will become Gravemind

Sure. All what is in the blockchain is static, but would be very resource intensive to update it every 10 min so it will be only an incremental upload every week for standard virtual minds. (for premiums every day)
But every 10 minutes the hash of the incremental change will be updated and the incremental changes will be backup-ed on more servers until it will be uploaded in the blockchain.
The servers must have a 99.99% running up-time guaranty so once a year could happen that results of 10 min thinking of a virtual mind get lost.
That would be not tragical, it is just as would you sleep 10 minutes. The world has gone forward but you was not aware of it.
Another limitation will be that only 1% of your virtual minds content can change/month(12%/year). This would be not only to use less resources but also to protect them and would be a little bit higher then the average changing rate of a healthy biological brain's content.
For increased security the minds will run on one of many Virtual Minds Application Server's secured environment. The Server will be chosen randomly for every mind.
The World Future Intelligence Agency will make pressure on companies to implant Random Generator weakening measures in their products. This way they hope that in short time when they will be ready with a supercomputer, they could predict which mind when and where will run.
So the blockchain alone will be not enough to secure the virtual minds against manipulations. A very engaged developer team will supervise that all is running well.
A genial programmer of a Virtual Minds Application Server will show a bug how some parts of virtual minds could transferred to other mind but another programmer FutureSnailbrain2 will fix it quickly before any harm happens. He will receive as reward from the Namecoin2 Foundation that his mind will be uploaded for free and hosted forever in the Namecoin2 blockchain as life/FutureSnailbrain2 namespace entry.
 :) :) :)

There will be a SilkBrain, who will trade code snippets which will enhance Virtual Minds speed. This snippets could be even implanted in a biological brain with nano harpoons which will be traded illegally. SilkBrain developed with some others his programms and implanted them in his brain to test them. Others followed him. He became half genious-half crazy.
http://www.wired.com/wiredscience/2010/04/silk-brain-computer-interface/
Many people will become crazy by using this technology. Others will become more intelligent and will worship SilkBrain.
So The World Future Intelligence Agency will chase SilkBrain, the evil mind.

No. But I will think about it. Thanks. You know a lot of things what I don't know.

Look at this man.
He also wants to live forever.
http://www.wired.com/wiredscience/2013/10/paulallenqa/
A couple of billionaires and the project can be financed.

hey thats interesting actually but consider this philosophical thingy:

if time passes and your mind is not switched on, then you are not the same person.

you will look 100% identical and HE will feel like YOU for sure. Other will think it is you.

Man is tied to the time-continuum.

As long as their is a gravemind we will all be fine
