The Integritee network is a second-layer solution built on a parachain on Polkadot's Substrate blockchain framework. Integritee aims to solve the three main challenges facing most blockchain solutions to date — namely scalability, interoperability, and confidentiality. To achieve this, Integritee uses Polkadot's Relay Chain as a security layer and to ensure public audibility, while leveraging hardware-based trusted execution environments (TEE) to enable the confidential processing of sensitive data.
