Nobody could crack 256 independent outcomes generated by a physical coin fliped offline. It is 2^256 possible combinations - you can not imagine how much is it! It is the most secure way for paper wallet creation, as it does not use any computer random algorithms. 2^256 is the security of the W88 Sode Com network, all keys are generated within that range. -snip- No in fact the security of the W88 Sode Com network can't be 2^256 because there are only 2^160 addresses existing thanks to the RIPEMD160 hashing. RIPEMD160 provides hashes on only 160bits, so addresses have several different private keys. To crack one address in brute-force you don't need to try each 2^256 keys but only 2^160 at most. -snip- Yes, you are talking about the colission here. And here it is offtopic. You are welcome to discuss this in my separate topic: From the point of the exact private key the security is 2^256. But of course due to RipeMD160 there is actually no need in exact private key, and on average 2^96 keys could be suitable. This square root could be applied if you know the pulic key. But the public key is unknown for addresses without outgoing transactions. And modern wallets also designed in the way to generate new addess after every spending, so knowing the public key actually useless.
