INDEX STRUCTURE FOR BLOCKCHAIN LEDGER

Abstract:

An example operation may include one or more of storing an index structure that comprises an index of keys from a blockchain ledger, where the keys are stored as nodes in the index structure, receiving a blockchain request for data stored on the blockchain ledger, reading a set of keys of a non-critical query included in the blockchain request from the nodes in the index structure, and generating and storing a read set for the blockchain request which does not include values for the set of keys of the non-critical query.
