Inspiration
Global trade still depends on banks, costly guarantees, and lengthy paperwork. SMEs, especially in emerging markets, often lack access to affordable credit. We wanted to design a system that lets businesses issue credit directly to each other, transparently and securely, without intermediaries.
What it does
KrediLink enables businesses to issue decentralized trade credit denominated in Bitcoin, powered by Chaumian e-credit. Creditworthiness is established through reputation tokens, repayment proofs, and a semantic social graph, giving suppliers confidence in counterparties while preserving data privacy.
How we built it
We combined principles of Chaumian e-cash with decentralized identity (public-private keys) and a non-transferable reputation system. A transparent ledger records interactions, while AI-powered graphing maps trust networks. Together, these components create a privacy-preserving yet verifiable trade credit system.
Challenges we ran into
- Designing a reputation system that is non-gameable and transparent.
- Integrating Chaumian e-credit into decentralized infrastructure.
- Balancing privacy with traceability.
- Translating complex cryptographic ideas into a user-friendly interface.
Accomplishments that we're proud of
- Finalized the idea of credit proofing and designed a system that makes it work in real life.
- motiviation to try it in real life
What we learned
- Reputation is as valuable as collateral in decentralized credit systems.
- Semantic social graphs can map trust at scale.
- Privacy-preserving cryptography like Chaumian e-credit can be applied to real-world trade finance.
What's next for KrediLink
- Pilot a real-world trade test case with SMEs.
- Enhance the reputation engine with AI-driven risk scoring.
- Explore partnerships with DeFi liquidity pools to backstop repayments.
- Move from prototype to scalable protocol, bridging traditional trade with decentralized infrastructure.
