As far as I know you can change your keys for your bitshares account. Can you please provide some good link on The Large Bitcoin Collider experiment? I don't think it's possible to randomly get a key with BTC, probably some fear-mongering.
Are you saying I am fear-mongering? I hope not because the fear is valid. Official website of LBC:
https://lbc.cryptoguru.org/aboutNot you, but crypto space has seen all kinds of most sophisticated FUD for years. Large Bitcoin Collider need provide some proofs of finding random users (not their own) wallets. If it's real this will be big news.
In that case, I apologize for misunderstanding you. I believe someone who has good knowledge of blockchain, cryptography should analyze this project. They already have provided details on their website but it's just too technical for me to understand.
A non-technical summary of this project is as follows:
The "Large Bitcoin Collider" (LBC - a homage to LHC) is a distributed effort to find at least one collision of private Bitcoin keys by creating addresses to private keys in a continuous 2160 range. These are checked against the list of known BTC addresses with funds on them. In the rare event of a collision, the funds on the address in question would become accessible to the collision finder.
Last night I downloaded their client and successfully deployed it using a Linux virtual machine. The project itself seems definitely legitimate however just like you I wonder the validity for their claim but I don't see anyway they can prove this. But this does not mean they are a scam.
Instead of creating more and more cryptocurrencies on an almost daily basis, developers need to focus on security of addresses. If I make a significant investment in a cryptocurrency and leave it for say, 20 years, I don't want to think of the possibility of someone randomly going through private keys of addresses to come across my address which contains my hard earned money.
In another forum where I had this same discussion, I got a response saying that this wouldn't be possible and that it is "like this by design". This just isn't an acceptable answer. Tell that to the guys who wanted to go the moon.
