Message class

Bitcoin Signed Messages

The Bitcoin Signed Message "standard" takes a novel approach in relying on our ability to recover a Public Key from an ECDSA signature. Once we have the public key recovered we can then generate a corresponding bitcoin wallet Address and verify that an address corresponds to a signature.

Private Key (is used to generate) ---> Signature (is used to recover) ---> Public Key (is used to create) ---> Address
