Random node selection for permissioned blockchain

Abstract:

An example operation may include one or more of retrieving a block hash of a data block stored on a blockchain, randomly determining a subset of peer organizations from a blockchain network of the blockchain to be endorsers based on a value of the block hash, transmitting a blockchain storage request from a client to the randomly determined subset of endorser peer organizations, and collecting simulated responses from the randomly determined subset of endorser peer organizations into a storage request proposal.
