because at first you made mention of something quote "you should find any relation between similar addresses and their public/ private keys with their sha256 hashes"... with that said, what kind of relationship are you talking about? besides that, I thought hashes are one way and cannot be calculated the other way unlike the EC curve that is based solely on the SECP256K1 implementations, one point linking to another point on the curve... I might be wrong though. Can you expatiate how we can successfully find the relation between addresses and their hashes...
Anything is always possible and I always keep a good faith...
Don't go after hashes and addresses, that is for tech giants not for puzzle solvers, anyone trying to find relations between addresses and hashes is lifting more than he could/ should, because after breaking 2 hash functions which is equal to breaking a 256 bit key, you will have to deal with the public key, you could however solve 66 up to 124 in a few month using kangaroo but breaking 2 hash functions is not something easy.
A group effort is needed to partially break ECC and solve the keys 130, 135 etc, it doesn't matter if someone uses our ideas to solve the puzzles and keep the coins, what matters is us throwing as big as we can find at ECC's window to see when it cracks.
And when we start seeing cracks on the glass, we could think of more protection before billions of dollars and millions of lives are ruined.😉
