The End of Overcollateral: How AI-Powered Credit Scoring Is Unlocking DeFi's Capital Efficiency Problem
Imagine walking into a bank and being told: to borrow $100, you first need to hand over $150 in cash — and keep it locked up the entire time. You would walk out. Yet this is precisely how decentralized finance has operated since its inception. DeFi's overcollateralization model has protected protocols from default, but it has also locked out billions of dollars in potential borrowers and trapped trillions in idle capital. That calculus is now shifting. AI-powered credit scoring, fed by the richest behavioral dataset in financial history — the public blockchain — is beginning to make under-collateralized DeFi lending a practical reality rather than a futurist promise.
