摘要： Disclosed in the disclosure are a reconciliation method, apparatus and system based on a blockchain, relating to the technical field of blockchains. A specific embodiment of the method includes: acquiring a batch hash value corresponding to a reconciliation batch transaction record fed onto the blockchain by an institution to be reconciled and a batch hash value corresponding to a reconciliation batch transaction record fed onto the blockchain by a transaction reconciliation platform respectively; performing first comparison on the batch hash values; notifying the institution and the transaction reconciliation platform to feed shard hash values corresponding to the reconciliation batch transaction record under the condition that a result of the first comparison shows inconsistence; acquiring an inconsistent shard by performing second comparison on the shard hash values; notifying the institution and the transaction reconciliation platform to feed record hash values onto the blockchain; acquiring an inconsistent transaction record by performing third comparison on the record hash values; and notifying the institution and the transaction reconciliation platform of the inconsistent transaction record. According to the embodiment, a storage space of a blockchain can be saved; reconciliation efficiency is greatly improved, and a reconciliation result cannot be tampered with; and the problem of data privacy on a chain is solved.
