METHOD AND SYSTEM FOR DESYNCHRONIZATION RECOVERY FOR PERMISSIONED BLOCKCHAINS USING BLOOM FILTERS

Abstract:

A method for recovery of missing or extra data using a bloom filter includes: storing a plurality of transaction messages, each including a transaction value; generating a bloom filter of the transaction messages, the bloom filter being generated using a number of hash rounds and with a size at least double the number of transaction messages; generating a recover message including the number of transaction messages, the number of hash rounds, the size, and the generated bloom filter; transmitting the recover message to a consensus node; receiving a response message from the consensus node, the response message including at least one additional transaction message; and inserting the at least one additional transaction message into the plurality of transaction messages.
