The privacy-focused platform, formerly called Gitcoin Passport, aims to protect networks against bots and fake accounts.
Identity verification application Human Passport, formerly known as Gitcoin Passport, has rolled out new Sybil resistance tools for Ethereum Layer 2 (L2) Base to deter fake users and bots.
Base, which boasts a total value locked (TVL) of $6.6 billion, currently boasts nearly 34 million active addresses per month, according to Token Terminal.
A Sybil attack occurs when a single entity creates multiple fake identities to manipulate a system or network. In crypto, a Sybil attack can refer to the creation of multiple bots or fake identities in an attempt to gain undue influence or control of a blockchain, and can compromise security and privacy. This kind of attack is also often used during token generation events or airdrops, as the attacker attempts to acquire a disproportionate allocation of tokens.
Human Passport works by letting users collect “stamps” — verifiable credentials that prove the user is a real, unique human, without requiring them to share sensitive personal information.
Human Passport’s new tools for Base introduce a machine learning–powered Sybil Detection Model that analyzes wallet behavior in real time, according to a press release viewed by The Defiant. Users can also mint their Stamps-based score and identity data directly on Base without requiring further personal data for know-your-customer (KYC) procedures, or compromising privacy.
Earlier this year, the Holonym Foundation (HF) purchased Human Passport from Gitcoin and made it part of the human.tech ecosystem. The ID verification software now runs on the Human Network – an actively validated service (AVS) on EigenLayer with over $1.4 billion in staked assets to secure the network, according to HF’s blog.
The update also includes a tool called Cross-chain Intelligence, which combines activity across Base, Ethereum, and other EVM-compatible chains for more accurate verification, the release notes.
The rollout is a major step in Human Passport’s mission to offer simple, privacy-first tools that help communities verify real people and prevent abuse by bots.
“Base is exploding with activity, but where there’s growth, Sybils follow,” said Kyle Weiss, co-founder of Human Passport, in a statement. “Communities die when rewards go to bots, but with Human Passport on Base, we’re making sure that never happens.”
Shady El Damaty, the CEO of human.tech by Holonym, echoed the sentiment:
“Sybil resistance isn’t just about stopping bots, it’s about defending what it means to be human in a world where that definition is under siege.”
