Decentralized AI-Powered Credit Scoring (DAICS)

The world's first decentralized AI-driven credit system for DeFi loans, pioneered by Questdriem Echo.

The Undercollateralization Problem in DeFi

A major barrier to DeFi's growth is its reliance on overcollateralization. To take out a loan, users must typically lock up assets worth more than the loan itself (e.g., provide $150 of ETH to borrow $100 of USDC). This is capital-inefficient and locks out billions of potential users who don't have enough assets to use as collateral. This is necessary because, in the anonymous world of Web3, lenders have no way to gauge a borrower's creditworthiness.

The DAICS Solution: An On-Chain Credit Score

DAICS is a protocol built on XOLIXBlock that uses AI to generate a "credit score" for blockchain addresses. This score is based on a wallet's on-chain history, such as its transaction record, DeFi interaction patterns, governance participation, and loan repayment history. This allows DeFi protocols to offer undercollateralized loans to trustworthy borrowers for the first time.

Using our zk-ID technology, a user can prove to a lending protocol that they have a high DAICS score (e.g., over 750) without revealing their entire transaction history, preserving their financial privacy.

How It Works

  1. **Data Analysis:** The DAICS AI model analyzes a wallet's entire on-chain history across all supported chains (thanks to QOC). It looks for positive indicators (e.g., long history of repaying loans, providing liquidity, active governance voting) and negative indicators (e.g., interaction with known scam contracts, past liquidations).
  2. **Score Generation:** Based on this analysis, the AI generates a numerical credit score for the address. This score is dynamic and updates in real time as the user continues to interact with the blockchain.
  3. **Privacy-Preserving Proof:** A user can query the DAICS protocol to generate a Zero-Knowledge Proof that attests to their credit score bracket (e.g., "My score is > 750") without revealing the exact score or the data used to calculate it.
  4. **DeFi Integration:** A lending protocol can then request this proof. If the proof is valid, the protocol can offer the user a loan with more favorable, undercollateralized terms, knowing they are a reputable borrower.

Key Advantages

  • Enables Undercollateralized Lending: Unlocks a massive new market for DeFi by allowing protocols to lend based on reputation and history, not just collateral.
  • Preserves User Privacy: Users can prove their creditworthiness without exposing their entire financial history to the public.
  • Rewards Good Actors: Creates a powerful incentive for users to behave responsibly on-chain, as a good history leads to better financial opportunities.
  • Objective and Transparent: The factors contributing to the score are public, creating a more transparent and fair credit system than traditional, opaque models.
