Preservation of privacy of inputs

Abstract:

An example system may include a processor and memory, wherein the processor is configured to perform one or more of gather hashed commitments inputs from a plurality of user peers until a current time of a blockchain network equals to a hashed commitments inputs end time (t1), collect plain text inputs until the current time of the blockchain network equals to a plain text inputs collection end time (t2), wherein the t2 is greater than the t1, and execute a chaincode of the smart contract to: compare generated hashes of the plain text inputs against previously stored hashes, in response to a match, store the plain text inputs into an input array, and perform a compute function on the input array.
