KILT is a blockchain protocol that provides a platform for self-sovereign data and interoperability. It enables a fully decentralized claim-based trust market, empowering users to control and leverage their data across different platforms. KILT is built on Parity Substrate and uses the Proof of Stake (PoS) consensus algorithm. It also uses a novel approach to identity verification called the KILT Trust Graph, which is a decentralized network of trust anchored in the blockchain.
