Abstract
A blockchain data index method, a blockchain data storage method and a device are provided. This method first persists a block into a block file, persists an index data layer into an index database, then obtains a matching transaction location according to a query condition, and finally obtains a complete transaction from the block file. In the present application, through expanding the process of the blockchain data storage processing, the blockchain index data is stored in an independent index database and transaction atomicity of multi-database is guaranteed, and a data index mechanism, in which business information is customized in a transaction note field, and then a transaction is associated with the business information through the customized transaction note index field and finally the complete transaction is acquired based on key transaction information, is established.
