Abstract
Encrypted multi-stage smart contracts are disclosed. A smart contract that is to be performed by a contract executor in a plurality of successive stages is generated. For each respective stage of at least some stages, a package of data is encrypted with at least one key to generate an encrypted package that corresponds to the respective stage, and an envelope that corresponds to the respective stage is generated. The envelope includes a condition precedent confirmable by an oracle, and an encrypted package-decryption key that is encrypted with a key of the contract executor. The encrypted package-decryption key, when decrypted, is configured to facilitate the decryption of the encrypted package that corresponds to the respective stage. For at least some of the stages, the encrypted package comprises an envelope and an encrypted package that corresponds to a next successive stage.
