Bitcoin Forum

Hello guys, I was thinking about this topic, I know is impossible to know if someone has loaded my private keys on his wallet. But I think that is relevant information for the network, that would give more trust, and I know what are you thinking. Someone can copy the private key and not load it until he wants to steal the BTC, but at least would be nice to know if my online wallets or my exchanges accounts have a compromised addys.

I think this is necessary because the brute force attacks are getting better with time and lots of btc have been vulned this way. So, I was thinking this would be possible to do it like a transaction, once a private key get loaded on a wallet that information could go on the next block to be public for all.

And here is where the discussion starts, is possible with the right software upgrade, but do you think is really relevant information to be on the network?

It's been a long time since "The Large Bitcoin Collider" (https://lbc.cryptoguru.org/trophies) has found a private key corresponding to an address with a significant amount of BTC. Including such information in blocks would be inefficient and would exceed the size of transactions included in the block. How would you determine if someone used your private key on an offline computer? Transaction could be prepared on a watch-only wallet and then signed on that computer. There is no need to worry about address collision. Scalability issue is more important right now.

if it's included in the block, it takes up byte space and requires fee
not only that but I think it will reduce privacy and create a bloated blockchain with useless info
and even if this is implemented, to circumvent it "thief" can use watch-only address and sign tx offline

don't be confused by the name of the project and the things they say they have found. reality is this project has NEVER found any real private key that was created by a wallet with sufficient RNG. what they say they find is solutions to a puzzle that was placed there a long time ago.
in other words they are finding private keys that were supposed to be found.

It's highly unlikely for any attacker to wait and give you the chance to move your funds on your own.

In other words you want to destroy the basics of Bitcoin and exchange it for some fake feeling of security?

How exactly do you think you can force Bitcoin wallets to do this, especially considering the fact that a paper wallet or any offline wallet is enough to store the private keys?

I think that you really want impossible, and as others say when your private keys are compromised in 99% game is over for you. In some cases hacker will maybe wait before your account is wiped out, but only if he/she know that you receive regular payments on your address and not move them from that address for long time.

I see you are in the first place concerned about security of your online accounts, but such accounts can be very safe if you use unique strong password, 2FA and e-mail which is also have strong password and it is used only for that service. However all this will not help if your online crypto service is hacked, so do not store coins online ;)

Ok guys, after read all your point of view i realized how bad was the idea, at end look like it's irrelevant information who only gives 'some fake feeling of security'.

I want to thanks to pooya87, LoyceV, Lucius and ETFbitcoin for your answers, and you are right guys. This is just a bad idea and not a security solution.

There is no registering of private keys or addresses on the blockchain. That is just not how bitcoin works.
