METHODS AND SYSTEMS FOR BLOCKCHAIN-IMPLEMENTED EVENT-LOCK ENCRYPTION

This abstract first appeared for US patent application 20250132903 titled 'METHODS AND SYSTEMS FOR BLOCKCHAIN-IMPLEMENTED EVENT-LOCK ENCRYPTION

Original Abstract Submitted

a computer-implemented method includes encrypting a plaintext message to a cryptographic public key in accordance with an identity-based encryption scheme using at least a congress public key to generate an encrypted message, wherein the congress public key is associated with members of a congress, respective members of the congress having access to private key shares usable in a threshold decryption scheme in which at least a threshold of private key shares are sufficient to derive a decryption key through the combination of partial contributions to the decryption key on behalf of the congress, generating, using at least a cryptographic private key corresponding to the cryptographic public key, a digital signature over a first set of instructions to perform cryptographic operations upon an occurrence of an event; and broadcasting one or more transactions to a proof-of-work blockchain network, the one or more transactions comprising the encrypted message, the cryptographic public key.
