SHA512256d Algorithm

SHA512256d is a hashing algorithm that takes a SHA512 hash and truncates it to SHA256. Although SHA256 is already secure enough, SHA512256d was chosen to ensure a secure and battle-tested blockchain compatible with ASIC machines. This choice levels the playing field, fostering a truly decentralized, massively scalable, cost-efficient blockchain where no ASIC capable of mining RXD currently exists.
