Ethos
Ethos is an on-chain reputation protocol on Base where users vouch with staked ETH, leave reviews, or slash bad actors to build a portable credibility score.

What is Ethos?
Ethos is a credibility platform on Base that turns peer-to-peer reviews, ETH vouching, and slashing into a portable on-chain reputation score. Users review or vouch with staked Ethereum for people they trust and can vote to slash bad actors, with every action recorded by Ethos smart contracts. The Ethos Credibility Score combines those signals with wallet age, attestations, and Sybil signals, and can be integrated into Twitter and other apps via a Chrome extension and developer APIs.
