Consensus transaction scheduler

Abstract

An example operation may include one or more of connecting, by a scheduler node, to a blockchain network comprised of member nodes, receiving, by the scheduler node, a plurality of transactions that include deadlines from the member nodes, comparing, by the scheduler node, the deadlines of the plurality of the transactions against an average time to append to a ledger (ATAL) pre-calculated for the scheduler node, dropping, by the scheduler node, the transactions of the plurality of the transactions, if a sum of the ATAL and a current time is larger than the deadlines of the plurality of the transactions, calculating, by the scheduler node, a priority usage balance (PUB) for the member nodes based on the transactions of the plurality of transactions remaining after the transactions of the plurality of the transactions have been dropped, scheduling, by the scheduler node, a transaction with an earliest deadline from the plurality of the remaining transactions to be validated first for an execution, and arranging, by the scheduler node, a validation order for the plurality of the remaining transactions based on the PUBs.
