At the heart of the autonomous identity revolution
Major Milestone for Digital Trust: KERI Suite Specifications Achieve Ratification. Check it Here!
Key Event Receipt Infrastructure (KERI) is the first truly fully decentralized identity system.
Truly Decentralized Identity
KERI is the first truly decentralized identity system. KERI identifiers are truly portable, as there is no ledger lock-in, there is no central authority, and no compromise on privacy or security. It uses self-certifying identifiers and cryptographic key events to enable secure, portable, and verifiable identities across the internet. Think of it as the foundation for a trust-first digital world.
KERI is inherently supportive of GDPR (global data protection rights) compliance. KERI provides non-intertwined identifier trust bases which means that a given identifier’s data may be erased and truly forgotten.

Self-Certifying Identifiers
KERI has a decentralized secure root-of-trust based on cryptographic self-certifying identifiers, so trust doesn’t depend on any central authority. It uses hash chained data structures called Key Event Logs that enable ambient cryptographic verifiability. In other words, any log may be verified anywhere at anytime by anybody. It has separable control over shared data which gives each person or entity real control over their own identifiers and shared data.
The KERI Suite
The KERI Suite aims to make KERI easier to adopt and implement. It is a growing set of open-source tools and protocols that makes secure, decentralized digital identity possible. It allows individuals, organizations, and devices to prove who they are, control their own identifiers, and verify data authenticity across the internet, all while preserving privacy and autonomy.
The KERI Suite offers a resilient foundation for trust in critical sectors like finance, healthcare, IoT, and public services. The KERI Suite focuses on reducing complexity, so that anyone can deploy decentralized identity solutions with minimal effort and technical knowledge, across platforms and use cases.
By supporting the KERI Suite, you help create a more secure and privacy-first internet, that is open, scalable, and built for the future.
The KERI Foundation drives this development: We fund, maintain, and steward the open-source ecosystem that makes decentralized identity real and usable.
Funded development, guided by Dr. Samuel M. Smith, the creator of KERI.
Our site is dedicated to the promotion, development, and support of the Key Event Receipt Infrastructure (KERI) protocol.
Co-founded by Sam Smith, the inventor of KERI, our foundation aims to create the infrastructure for the trust-spanning layer of the Internet, using the most open-source software license.
The foundation provides the financial resources to overcome any barriers.
