Abstract
Proof onions for transactions for smart contracts are stored. Details of the transactions are stored on blockchains separate from the proof onions. The proof onions are evidence structures for the steps taken to create any transaction for the smart contract. The proof onions include a plurality of signatures or other cryptographic proofs. A proof request that is associated with at least a first transaction of the transactions is received. A first proof onion of the proof onions that corresponds to the first transaction is retrieved. A plurality of public keys associated with the first proof onion is obtained. The plurality of public keys is used to validate the first proof onion. In response to the validation of the first proof onion, the proof request is responded to with at least an indication of the validity of the first transaction.
