BLOCKCHAIN-IMPLEMENTED DATABASE OVERLAY, VERIFICATION AND INDEXING SYSTEM

Resumen de: CN119731657A

The embodiment of the invention provides a database covering and indexing mechanism implemented by a block chain. In one embodiment, records in a database are associated with respective unconsumed outputs in one or more transactions on a blockchain by overlay. Each output includes a lock script that specifies which keys can be used to consume the output to other transactions. When a user wishes to access a given record in the database, the other (expending) transactions are generated and sent to a blockchain network. The other transactions include an unlock script that provides one or more keys required to meet the conditions of the lock script, otherwise a consensus mechanism of the blockchain will not allow expenditure of the output and access to the record will be denied. However, if a requirement is met, the output is consumed, and an access request is considered to be authorized. In this way, the consensus mechanism provides an improved authority control and user authorization scheme for a database. When the output is consumed by the other transactions, the overlay is updated to associate the record with the consumed transaction. Transaction logs can also be provided to quickly and efficiently regenerate the database when needed.
