Abstract
A method for using digital signatures for signing blockchain transactions includes: generating a domain key pair comprising a domain private key and a domain public key, wherein the domain public key is signed after generation; receiving a plurality of member public keys, wherein each member public key is received from an associated member of a blockchain network and is a public key in a key pair comprising the member public key and a member private key corresponding to the associated member; signing each member public key using the domain private key; receiving a transaction block from a specific member of the blockchain network, wherein the transaction block includes a plurality of blockchain transaction values and a hash signed using the member private key corresponding to the specific member; signing the received transaction block using the domain private key; and transmitting the signed transaction block.
