METHOD AND SYSTEM FOR USING DIGITAL SIGNATURES TO SIGN BLOCKCHAIN TRANSACTIONS

摘要

the present invention relates to a method of using digital signatures to sign blockchain transactions that includes: generating a pair of domain keys comprising a private domain key and a public domain key, where the public domain key is signed after its generation; receive a plurality of public keys from members, in which each member public key is received from an associated member of a blockchain network and is a public key in a key pair comprising a member public key and a private key from member corresponding to the associate member; sign each member public key using the private domain key; receiving a transaction block from a specific member of the blockchain network, in which the transaction block includes a plurality of blockchain transaction values and a hash function signed using the member private key corresponding to the specific member; sign the block of transactions received using the private domain key; and transmit the signed transaction block.
