As Base, the Ethereum L2 blockchain developed by Coinbase, continues its meteoric growth, bots, Sybil attacks, and airdrop hunters are swarming the network. Human Passport, formerly Gitcoin Passport, has launched a new suite of Sybil resistance tools built specifically for the Base ecosystem to safeguard its rapidly expanding user base.
Base, which recently surpassed over 50 million transactions in a single week, is now one of the fastest-growing Ethereum L2s, fueled by a surge in DeFi protocols, social applications, and Base-native airdrop programs. But with that success has come an influx of malicious actors.
“Communities die when rewards go to bots,” warned Kyle Weiss, Co-Founder of Human Passport. “With Human Passport on Base, we’re making sure that never happens.”
Privacy-First Identity Without KYC
The new Human Passport tools use machine learning-driven Sybil detection models that analyze wallet behavior across Base and other EVM chains. The system generates a cross-chain, onchain verifiable score — users can mint this “Stamp” directly on Base — offering projects an open and transparent way to verify humanity without invasive Know Your Customer (KYC) checks or black-box algorithms.
This approach is especially timely in the wake of the recent Coinbase breach, which highlighted the risks of centralized identity storage. Human Passport’s model offers an alternative: privacy-first identity verification that can scale alongside Base’s ecosystem.
Real-World Adoption, Real-World Savings
Human Passport’s system is already being tested in the wild. Projects like LayerEdge and Story Protocol have used it to screen hundreds of thousands of wallets, preserving the integrity of community airdrops and saving millions of dollars from Sybil abuse.
The move follows Human Passport’s acquisition by human.tech six months ago. Now operating as a public-benefit tech company, human.tech is focused on building privacy-preserving identity infrastructure designed to protect individual autonomy and digital dignity.
“Sybil resistance isn’t just about stopping bots,” said Shady El Damaty, CEO of human.tech, “it’s about defending what it means to be human in a world where that definition is under siege.”
The Bigger Battle for Digital Identity
As blockchain-based identity becomes a hotbed for innovation — and controversy — Human Passport’s model offers a third path between state surveillance systems and opaque corporate identity frameworks. With over 2 million users, $450 million in protected funds, and 35 million secure credentials issued, Human Passport is helping set a new standard for decentralized digital identity.
With Base’s growth showing no signs of slowing, the race is on to ensure the ecosystem remains human-first.
