How Are BlockSign transactions verified on the Bitcoin blockchain?
A BlockSign Transaction is a transaction on the bitcoin blockchain representing legally binding signatures on any document, contract, or agreement.
It can be any bitcoin transaction with at least one Pay-To-PubKey-Hash Input and at least one BlockSign Output.
Bitcoin Address) in the Pay-To-PubKey-Hash Input identifies the signer (or signers) while the hash digest embedded in the BlockSign Output identifies the document being signed.
Similarly a single transaction can contain multiple BlockSign Outputs, which simply means the signer(s) signed multiple documents.
BlockSign Outputs are embedded in the blockchain with the OP_RETURN opcode which means bitcoin clients not aware of BlockSign Outputs will simply ignore them.
