Lit Protocol provides distributed key management for encryption, signing, and compute. It is a blockchain-agnostic middleware network that enables the reading and writing of data between blockchains, state machines, and off-chain platforms with conditional decryption and programmatic signing. Lit is composed of a decentralized network of nodes that collectively generate keys, reach consensus, and execute network actions. It uses applied cryptography techniques such as distributed key generation, threshold secret sharing, and proactive secret sharing to ensure security. Lit also offers programmable and distributed MPC wallets for DeFi automation and access control solutions for secure data storage on the open web.
