WEIGHTED VERIFICATION OF ENTITY DATA BLOCKS ON A BLOCKCHAIN

Abstract:

Technologies are shown for validating data on a blockchain by a cluster of verification nodes, where nodes vote to verify a new data block with a corresponding class of service. The entity data block is submitted to the cluster for voting, where each node has an associated class of service. Votes received are weighted based on a relationship between the entity data block class of service and the verification node class of service to obtain a weighted vote. A verification score is calculated based on the weighted votes and checked against a verification threshold. If the verification score exceeds the verification threshold, the entity data block is verified on the blockchain. Also, a cluster can use weighted voting to accept a new node where votes are weighted based on a relationship between the new node's class of service and a voting node's class of service.
