Fairblock is building the infrastructure that can enable pre-execution privacy and conditional decryption. Fairblock enables users to seamlessly encrypt their transactions with a set of conditions for decryption and execution. Developers can leverage this framework to empower their protocols with a fuzzy logic for decryption and execution of transactions without exposing the contents of on-chain data before or during execution. Fairblock uses advanced cryptography schemes such as identity-based encryption, witness encryption, and soon fully homomorphic encryption for verification of conditions and decryption of transactions in a decentralized way.
