Method and system for proving integrity of distributed ledger based on a plurality of intelligent committee

A system for proving integrity of a distributed ledger on the basis of a plurality of intelligent committees, the system comprising:

• a first intelligent committee for electronic notarization including a first plurality of node devices performing a neural consensus proof-based block generation process according to a preset condition;
• and
• a second intelligent committee identifying a discrepancy between a plurality of ledger information clustered from the first plurality of node devices, verifying forgery of the plurality of ledger information on the basis of a result of identifying the discrepancy, and replying with ledger information, whose integrity is verified, to the first intelligent committee,
• wherein the first intelligent committee generates a block for updating ledger information of the first intelligent committee by using the ledger information whose integrity is proven,
• the second intelligent committee is an audit network based on blockchain,
• the second intelligent committee proves an integrity of a distributed ledger by using a second consensus algorithm that operates independently from the first intelligent committee,
• the first intelligent committee verifies forgery of a different plurality of ledger information of the second intelligent committee and replies with a different ledger information, whose integrity is verified, to the second intelligent committee, and
• the second intelligent committee generates a block for updating ledger information of the second intelligent committee by using the different ledger information whose integrity is verified.
