FIELD: data processing.
SUBSTANCE: invention relates to a method, a computer-readable medium and a transaction request processing device. Method comprises obtaining transaction data of a target transaction, in which a plurality of transaction nodes participate, determination of transaction holding according to data holding, which is generated on the basis of transaction data and which is signed by all transaction nodes involved in the target transaction, wherein the transaction data cannot be obtained back through the data dedication, the plurality of transaction nodes comprises a first transaction node and one or more second transaction nodes, generating a transaction request containing a transaction exclusion and not containing transaction data, wherein the transaction holding enables to perform consensus verification without transaction data, and broadcasting a transaction request to consensus nodes, causing each of the consensus nodes to maintain a transaction exclusion from the transaction request to the blockchain after the transaction has undergone consensual verification, wherein a plurality of transaction nodes and consensus nodes are blockchain nodes from a blockchain network.
EFFECT: technical result consists in improvement of safety of transaction request verification.
