The address is derived from the public key by a series of three steps: applying the SHA256 hash function to the public key applying the RIPEMD 160 hash function to that finally adding a value called a checksum for error correction purposesso that if you accidentally mistype a single character when. Because the hash is seemingly random, it is prohibitively difficult to try to produce a specific hash by changing the data which is being hashed. This is largely due to the proof of work functionSHA256) being reasonably simple and not requiring much RAM. SHA1 Hackage 26 січ.
