Abstract
Systems and methods described relate to executing, by a third computing entity different from a first computing entity and a second computing entity, a smart contract generated by the first computing entity and the second computing entity. A verification key is determined based on a power of a secret, the power of the secret being based on first and second sets of elliptic curve points. The smart contract comprising a first input from the first computing entity and a second input from the second computing entity are received. The smart contract is executed by computation of a function on an input to produce an output. A proof of correct execution of the smart contract is produced. A blockchain transaction is generated using an output of the smart contract. The generated blockchain transaction using the verification key and the proof of correct execution is validated by a fourth computing entity.
