Parallel transaction validation and block generation in a blockchain

Abstract:

An example operation may include one or more of identifying pending blockchain transactions in a transaction queue, determining states of the pending blockchain transactions, determining whether the pending blockchain transactions in the transaction queue are valid based on the determined states, retrieving a list of potential blockchain transaction conflicts associated with the pending blockchain transactions, and determining whether any conflicts exist for one or more of the pending blockchain transactions based on the list of blockchain transaction conflicts.
