Coinbase CEO Says On-Chain Reputation Will Replace Traditional Credit Scores

Coinbase Chief Executive Officer Brian Armstrong said "on-chain reputation," based on blockchain transaction and repayment records, could replace traditional credit scores.

BeInCrypto reported on August 31 that Armstrong recently wrote on X, formerly Twitter, that "on-chain reputation will soon replace traditional credit scores." He cited FICO scores, widely used in U.S. lending decisions, as a leading example of the existing system.

Armstrong made the comment in response to Jesse Pollak, creator of Coinbase's Ethereum layer-2 network Base. Pollak had mentioned the growth of on-chain credit markets that provide loans with no collateral or only limited collateral.

On-chain credit assessment uses publicly available blockchain data, including a wallet's transaction history, repayment record and length of use, to judge creditworthiness. Unlike traditional credit-rating firms, which manage such information centrally, multiple lenders can review the same public data.

Credifi, an on-chain lending service, offers unsecured loans of up to $3,000 to wallets with scores above 1,800 on Ethos, an Ethereum-based reputation service.

Still, the model has limitations. A wallet address alone cannot fully verify a user's identity. Because users can abandon an existing wallet and create a new one, it remains unproven whether on-chain records alone can accurately assess repayment capacity and default risk.
