Bitcoin Forum

Bitcoin was originally designed to allow everyone to participate in mining, but now ordinary people in Bitcoin cannot participate in mining. The computational power is concentrated in several large mines.
Both Bitcoin and Ethereum can theoretically be centralized through huge amounts of money.
Can a new blockchain technology be designed to optimize Bitcoin blockchain technology from the bottom.
First of all, this blockchain technology must be that one person can only own one node. Otherwise, if a person like Ethereum has enough funds, it means generating enough nodes. That's how to go to the center. Bitcoin also means that a person can use huge funds to generate huge computing power, and that's how to go to the center.
The blockchain technology that I will design next is truly decentralized.
First, copy the underlying code of Bitcoin
Through face recognition technology, each person can only generate one node, a private key, and a public key.
By setting an upper limit on the computing power of each miner, it is possible to mine on a mobile phone without consuming too much computing power.
If we are interested, we can design such blockchain technology to run on mobile phones together.

Blockchain networks for CBDC with a face recognition feature is going to be a new trend. I guess tomorrow, on April 1, there will be many announcements on this matter. ;D

And what makes you think that face (or iris, or fingerprint,...) recognition technology cannot be fooled?

Why would CBDCs need a blockchain anyway?

Yes of course as you say it can be done through identities. But then you have something very different than Satoshi's idea. You have a system where every single person on the network must be identified. Of course a system can be designed that puts limits based on identity (distribute mining rewards evenly, only allow one address per person), but then you have no privacy. Also this relies on the idea that no one can spoof someone's identity through whatever identity recognition system is used.


The reason Satoshi used PoW is because you can't spoof processing power. And of course he wanted to avoid the hassles and issues involved with identities.

Perhaps the Worldcoin project has verified the feasibility of matching unique nodes for face recognition, but its tokens are concentrated in the hands of developers and investors, which is unfair to ordinary people. In addition, he does not have a mining mechanism like Bitcoin, and may also be a token for making money rather than doing a good job in blockchain

Regarding face recognition, there is no privacy for the unique node. This may be another development direction of blockchain, which can prevent legal elements from using token transactions. The most important thing is that everyone can use mobile phones to mine, so that blockchain data can be distributed on everyone's mobile phones. Is it safer and more accessible for ordinary people to participate

I can find your face by just looking up your social media account, mean while can you discover the scalar that leads to these coordinates when multiplied by the secp256k1 curve Generator? :

If not I believe bitcoin is much more sound than your facial recognition scheme, do you want someone trying to cut your face off to access your funds? Is that better than protecting against data breaches really?

Face recognition on your mobile phone. You use it every day, and it won't affect your use because of your aging changes, will it

Stealing my facial images or videos cannot be obtained through face recognition, just as you cannot use photos or videos to recognize faces on your phone. A face can generate a corresponding string of codes, but this code cannot infer what a person looks like.

That is not true, for instance if your apple face id data was leaked you would never be able to use your face for security again as the same exact data could be used to break the following lock.

Not to mention that a government authority would then have the REASON to strap you down to a chair, peel your eyes open, and make you stand still while they scan your face to extract blockchain data. This is a terrifying idea.

Your idea boils down to using biometric information to generate a private key. This idea has been discussed here before:

The government has tied me to a chair and left me standing with my eyes open, unable to scan my face and extract my blockchain data. What is the difference between tying my body directly and asking me for my bank card password? If this is a security risk, then you know that your bank card password also has the same problem.

Sounds terrible. First of all, why would you want to intervene in miners' belongings? What's the problem with one individual owning more than 100 others do? Secondly, why do you find this more decentralized? To forbid someone from using multiple faces, KYC must be implemented; and even that way, you can't be sure the mechanism won't be violated. Thirdly, how will the minting work?

Yet, another well intended idea which would have opposite results.

First of all, if I don't interfere with the miners' computing power, it will become more and more concentrated in the hands of wealthy people like Bitcoin. "A person who owns 100 other people's facial codes is stealing other people's information. If it is approved by others, why not?". Each of us is a node of the blockchain, and we can also give up the power that the blockchain gives us. The operation of coinage is that everyone is mining with their mobile phones on

Is ETH really decentralized? Can you think about it carefully and see if he changed the underlying code from pow to pos after all the nodes voted for it? Will these miners agree to convert to pos? Their development team can change the underlying code themselves, and this power is concentrated in a few hands

You are now just being delusional, if the government does that very thing to you they WOULD be able to access all your blockchain secrets immediately (assuming people actually used your insane face id chain) it would be trivial as THEY NOW HAVE COMPLETE ACCESS TO YOUR ENTIRE REAL FACE AND HEAD.

As for how is this a bigger security risk than a bank? It is just as insecure as a bank, BITCOIN is way more secure than this scheme because private keys can be stored OFF OF YOUR BODY.

The government can force me to perform the facial actions required for face recognition, and similarly, it can force me to say the bank card number and password, or the private key of Bitcoin. In terms of absolute power, no encryption technology will work. Bitcoin is not stored outside of my body, it is also stored in my brain.

But this is decentralization. The absence of a central point which intervenes in the market to keep what it considers as balance. What you propose might sound as a good idea in your head (I strongly disagree), but it's by definition in favor of centralization, which contradicts with the title.

Because then a facial code market will be created, and what you're trying to prevent will inevitably happen; that is, to mitigate from an oligarchy of minters.

I dont believe you or anyone truly remembers their private key if its any good, the real security of a private key comes from the discrete log problem and opting in to remembering it is your way of attaching a biological security vulnerability to it. There is nothing in bitcoin core that forces you to memorize your private key, its 100% optional.

If you destroy the whole concept just to make it more accessible you haven't done anything good.

Sure you can do one-id-one-vote mining but in order to do that you are going to have to rely on trusted third parties, and then you no longer have decentralization. Facial recognition wouldn't work well because you'd have people stealing other people's faces and generating fake faces and whatnot.

Also at this point you wouldn't be "mining". There would be no point in PoW mining if this is your setup because the idea you've set forth is to make the minting process available to anyone so you're not using competition for resources any more. You're using a identification system, where it is decentralized and secured through IDs. So in your setup there is no mining, there's just running your ID node from your phone and you are participating in the transaction verification network.

Anyway, since the essence of your system is based on identification what you really need is to involve trusted third parties that can verify IDs. There must be a whole legal apparatus put in place in case someone steals someone else's ID on the network. At which point instead of creating a more decentralized Bitcoin you've created a centralized trust-required crypto-banking industry with universal basic income. That's a very different thing.

Mobile phone transfer face recognition, mobile phone lock screen face recognition, and identity verification face recognition in your life are all based on trusted third parties. Why can they use a trusted third party when I just want to generate unique code using face recognition instead of using a trusted third party? Does anyone in your current life steal your face to unlock your phone, or transfer money through the stolen face?
"I just want a person to have only one node, and face recognition is the most feasible method I can think of currently.". Why must a person have only one node? Because if it weren't for this, the power of the node would be concentrated in the hands of wealthy people, like Bitcoin and Ethereum today.

Although I cannot remember the number of the private key, I can remember the specific location where the private key password is stored

Which is not on your body.

Most people dont need to memorize their private key so they dont.

It is much easier to hide information.

you didn't address the issues with your idea. you just restated your idea.

Are you wrong? Do you seriously think that there are so many miners in Ethereum who will agree to switch from pow to pos? The development team can change the underlying code of Ethereum itself, and in the future, Ethereum will only develop in a direction that is beneficial to developers. Don't trust any currency except Bitcoin now.

There is nothing decentralized about Polygon or Ethereum
