The importance of On-chain reputation

On-chain reputation is presented as a needed layer for crypto, where users must judge the trustworthiness of counterparties without third parties like credit bureaus. The article says reputation systems would need to be a common cross-chain standard, citing a16z's call to map off-chain experiences on-chain and the Base team's comparison of reputation to a FICO or Google PageRank score. It highlights Gitcoin Passport, which aggregates identity stamps into a Default Humanity Score with a minimum of 20, and Ethos Network, which uses staking, vouching and slashing to produce a Credibility Score. The article also says challenges remain, including keeping systems decentralized and preventing reputation from being gamed or purchased.
