LITEX is a complete Layer 2 framework for consumer-level blockchain applications. The entire framework is divided into two parts: on-chain contract and off-chain protocol. The on-chain contract is a rule publicity platform that aims to fix the state and logic in the consensus layer, and provides various templates such as payment channel contract and business verification contract, etc. The offchain protocol is a rule execution platform that aims to process the data organization, transmission and verification of data off the chain and provide data credibility, data protocol and authentication protocol. LITEX provides developers with a verifiable, low-threshold, user-friendly, free-to-develop solution from end users’ perspective.
