1. A system, comprising:
a distributed ledger stored on physical peer-to-peer network nodes having a smart contract related to a problem statement, the smart contract enabling a zero-knowledge proof concerning the problem statement,
wherein the zero-knowledge proof is based on a validation function which takes a putative solution and returns a score that represents the quality of the putative solution,
wherein the smart contract defines a function which is configured to be called on smart contract creation by a Requestor, wherein the function is configured to record a timestamp after which no further solutions will be accepted by smart contract and before which Requestor cannot withdraw a bounty.
