METHOD AND DEVICE FOR CONSENSUS VERIFICATION Russian patent published in 2020 - IPC G06F21/62 

FIELD: physics.

SUBSTANCE: invention relates to the field of operation with blockchain. Control unit is responsible for verifying whether the request for a transaction is valid or not. If the transaction request is valid, the regulatory unit generates a digest based on the confidentiality data in the transaction data and sends digest and confidentiality data included in said transactions to each consensus node for consensus verification. Each consensus node stores digest and confidentiality data in a blockchain after consensus verification is completed successfully. In this regard, consensus node does not receive confidentiality data and therefore does not store privacy data in blockchain. As a result, confidentiality data are not disclosed.

EFFECT: ensuring confidentiality of a blockchain node, which participates in a transaction, during consensus verification.
