ENABLING CONSENSUS IN DISTRIBUTED TRANSACTION PROCESSING SYSTEMS

Abstract:

A distributed transaction processing system, comprising a peer node associated with a blockchain network. The peer node may be adapted to record join-time parameters for a plurality of blockchain nodes, compare a first join-time parameter for a first node of the plurality of blockchain nodes to a remainder of the join-time parameters for a remainder of the plurality of blockchain nodes, calculate, based on the comparison, a transaction signature probability (TSP) for one or more nodes within the plurality of blockchain nodes, select according to the calculated TSPs, a signature node from among the one or more nodes having calculated TSPs to sign a transaction block, and calculate, by the selected signature node, a digital signature for the transaction block.
