Abstract
An example operation may include one or more of receiving a data block for storage on a blockchain from an orderer node, the data block comprising a full-step hash of a storage request and a reduced-step hash of the storage request, performing an approximate hash verification on the data block based on the reduced-step hash of the storage request included in the data block, and in response to a success of the approximate hash verification, committing the data block among a hash-linked chain of data blocks stored within a distributed ledger of a blockchain.
