what's Kwil?

Kwil is a decentralized database platform designed for Web3 applications, enabling the deployment of permissionless relational databases as standalone Byzantine Fault Tolerant networks. Built on PostgreSQL for enterprise-grade reliability and Tendermint for consensus, it supports SQL smart contracts that allow developers to execute complex business logic, integrate oracles, and extend functionality with modular components. Key features include scalable data storage for dApps, asymmetric signature schemes for secure access control, and chain-agnostic interoperability. Kwil powers data-intensive protocols by providing a familiar SQL interface while ensuring decentralization, making it suitable for use cases like identity networks (e.g., idOS), DePIN, and RWAs.
