Pendulum Protocol (hereafter referred to as PEND) is a secure and scalable Layer 2 decentralized database protocol that provides mainstream blockchains with infinitely verifiable decentralized data oracles and computation oracles, connecting on-chain smart contracts with off-chain internet data while offering infinite verifiable computational capabilities. Developers and DApp companies using Pendulum Protocol consume data through public smart contract data points rather than relying on centralized oracles detached from the blockchain. This ensures security while leveraging existing internet data, bridging the gap between Web 2.0 and Web3.0 use cases and enabling more real-world business applications.
