Method and system for desynchronization recovery for permissioned blockchains using bloom filters

A method for recovery of missing or extra data using a bloom filter, comprising:

• generating, by of a processing server, a bloom filter of a plurality of data messages stored in a data database, wherein the bloom filter is generated using a predetermined number of hash rounds and has a size of at least double a count of the plurality of data messages, wherein each data message includes a structured data set related to a blockchain data including at least a data value;
• generating, by of the processing server, a recover message, wherein the recover message includes at least the count of the plurality of data messages, the predetermined number of hash rounds, the size, and the generated bloom filter;
• electronically transmitting, by a transmitting device of the processing server, the generated recover message to at least one node;
• receiving, by a receiving device of the processing server, a response message from the at least one node, wherein the response message includes at least a second bloom filter, an indicated number of hash rounds, an indicated filter size, and a number of expected data messages;
• identifying, by a data identification module of the processing server, at least one data message of the plurality of data messages not included in the second bloom filter based on the included data value and the indicated number of hash rounds, indicated filter size, number of expected data messages, and second bloom filter;
• and
• executing, by of the processing server, a query on the data database to delete the at least one identified data message.

• a transmitting device of the processing server configured to electronically transmit the generated recover message to at least one node;
• a receiving device of the processing server configured to receive a response message from the at least one node, wherein the response message includes at least one additional data message;
• and
• of the processing server configured to execute a query on the data database to insert the at least one additional data message.
