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.

Claim (Index 5):
A system for using digital signatures for signing blockchain transactions, comprising:\n a transmitting device of a processing server; a generation module of the processing server configured to generate a domain key pair comprising a domain private key and a domain public key, wherein the domain public key is signed after generation; a receiving device of the processing server configured to receive a plurality of member public keys, wherein each member public key is a public key in a key pair comprising the member public key and a member private key corresponding to an associated member; and a signing module of the processing server configured to sign each member public key of the plurality of member public keys using the domain private key, wherein the receiving device of the processing server is further configured to receive a transaction block from a specific member of the blockchain network, wherein the transaction block includes a hash signed using the member private key corresponding to the specific member, the transmitting device of the processing server is further configured to electronically transmit each signed member public key to one or more members of the blockchain network, the receiving device of the processing server is further configured to receive a new transaction block and a signed second hash value from the specific member of the blockchain network, the signing module of the processing server is further configured to sign the received new transaction block using the domain private key, and the transmitting device of the processing server is further configured to electronically transmit the signed new transaction block for validation by a member of the blockchain network.
