BLOCKCHAIN TRANSACTION GENERATION METHOD AND BLOCKCHAIN BLOCK VALIDITY VERIFICATION METHOD Russian patent published in 2023 - IPC H04L9/00 H04L9/32 

FIELD: blockchain.

SUBSTANCE: invention relates to methods, system and apparatus for generating a blockchain transaction and verifying the validity of a blockchain block. The method generates a transaction by the first node of the blockchain, adds a cryptographic signature to the transaction using the private key of the first node, thereby creating a signed transaction, broadcasts the signed transaction to a plurality of other nodes in the blockchain, while the other nodes verify the cryptographic signature of the signed transaction using the public key of the first node, wherein said other nodes check with the trusted entity whether the public key of the first node is valid, and the trusted entity is a blockchain node, if the public key is not valid, said other nodes reject the transaction generated by the first node.

EFFECT: increase in the reliability of verification of the generated block and the blockchain transaction.
