I read in this Github pull that Bitcoin relies on weaker cryptographic guarantees than SHA256. What are the weaker cryptographic guarantees being referred to? Could it be that RipeMD is 160 bits? ...
I'm trying to understand better how bitcoin works and I'm stuck. I've read a blog showing how to construct the WIF from the 256-bit secret integer and up to that point, I think I follow. However I'm ...
We are trying to build a much simpler version of Trezor. We do have an finished PCB design from a previous project and would like to know whether this design can be modified, without changing the ...
I'd like to use Bouncy Castle to generate the keypair for use with all *coin variants. Is this the correct implementation to get the correct ECC curve that the *coin variants use? ...
Bitcoin is unique that is uses secp256k1 to secure it's transactions; and any cryptographic attack against this algorithm is probably going to be percieved as an attack against the bitcoin network. ...
