KILT Protocol is a Polkadot parachain providing decentralized identity (DID) and verifiable credentials infrastructure, enabling individuals and organizations to issue, hold, and verify digital credentials without trusting a central authority with raw personal data.
The Problem KILT Solves
Traditional digital identity systems have critical flaws:
- Centralized databases: Facebook, Google, and governments hold your identity data and profit from it
- Privacy violations: Businesses requiring KYC must collect and store sensitive documents
- Siloed credentials: A degree verified on LinkedIn can’t be reused without re-verification elsewhere
KILT enables a paradigm where credentials are issued once, controlled by the user, and verifiable by anyone — without the issuer needing to be online, and without exposing raw documents.
Core Concepts
| Concept | Role |
|---|---|
| Decentralized Identifier (DID) | Self-sovereign identity anchored on KILT blockchain |
| Claim | Statement about an identity (e.g., “over 18”, “KYC passed”) |
| Credential | Signed, verifiable version of a Claim issued by an Attester |
| Attester | Entity that issues and signs Credentials (e.g., KYC provider, university) |
| Verifier | Entity checking a Credential (e.g., DeFi protocol, employer) |
Business Adoption
KILT is used in:
- SocialKYC: A privacy-preserving KYC service where credentials are issued to user-controlled wallets
- DIDsign: Tool for signing documents with blockchain-verified decentralized identity
- Enterprise KYC tools: Banks and compliance firms building on KILT infrastructure
KILT’s most notable enterprise partner is BOTlabs, the core development company, with additional B2B partnerships across European compliance and fintech.
