description The invention discloses a block chain-based data storage and search system and a method thereof. The system comprises an application programming interface module, which is used for responding to a call of an application layer to a block chain common chain intelligent contract; a user, role, authority management module, which is used to verify the user, role and authority of access block chain according to the algorithm, and verify the validity of each user's authority; a database module, which is used for updating the contents of the database and the block chain incrementally at a fixed time;a memory database module, which will put the database data in memory and directly call the intelligent contract and is used to update the contents of database and block chain incrementally at regularintervals. The invention combines the centralized database technology and the decentralized block chain technology, takes the block chain data as anchor point, and improves the operation efficiency ofthe block chain on the bas
