Self is an open-source identity protocol that uses zero-knowledge proofs to enable Sybil resistance and selective disclosure from passports, national IDs, Aadhaar cards, and KYC attestations. Self's Twitter Score is 41 out of 1000 as of August 2026, ranking #22,743 (top 5%) among 483,944 tracked accounts.
Self was co-founded by Marek Olszewski, Rene Reinsberg, Eric Nakagawa, Florent Tavernier, and Rémi Colin, all of whom were members of the Celo core team. Self Labs was started by this group in early 2024, and Self Protocol launched on February 25, 2025, following Self Labs' acquisition of OpenPassport, with which it was formerly affiliated. The protocol is also affiliated with Google Cloud, Spire, and Aave, and was previously affiliated with Privacy and Scaling Explorations.
Self announced a $9 million seed round on November 13, 2025, led by Greenfield Capital alongside Startup Capital Ventures x SBI Fund, Spearhead VC, Verda Ventures, and Fireweed Ventures. The protocol reported serving more than 8 million users worldwide as of July 23, 2025, and has since described its user base as exceeding 15 million. Self completed a three-week security audit by zkSecurity covering cryptographic dependencies, protocol circuits, smart contracts, and proof delegation through trusted execution environments. The protocol's own documentation acknowledges that its registration-and-disclosure design can be susceptible to timing attacks, with delayed first-disclosure proofs as the primary mitigation.
Self has published 2,203 posts on the platform and has been mentioned by 96 accounts a total of 371 times, reflecting active engagement within the identity and zero-knowledge proof space.
