Currently, the Layer2 ecosystem faces the core pain points of 'multi-chain identity fragmentation' and 'high trust costs of value flow'—user identity data (credit records, transaction history) is isolated across different Rollups, requiring repeated trust establishment for cross-chain collaboration; value flow relies on third-party intermediaries (such as guarantee institutions), which not only increases costs but also poses default risks. Caldera's breakthrough lies in constructing a 'Unified Identity Trust Network' to break down identity data barriers, creating a 'Decentralized Value Flow Engine' to reduce trust costs, allowing Layer2 to upgrade from a 'transaction layer' to a 'trusted value flow hub.'
1. Unified Identity Trust Network: From 'Identity Fragmentation' to 'Trusted Identity Reuse'
To address the issue of multi-chain identity isolation, Caldera innovates the 'On-Chain Identity Trust Graph (OCITG)': integrating user behavior data across various Rollups (loan performance, transaction compliance, staking records), generating 'Trusted Identity Scores' through federated learning encrypted computation, which are universally applicable across chains and can be authorized for user self-use. A certain user’s good borrowing record (no overdue payments) on Chain A results in an identity score of 85 points, allowing them to apply for credit on Chain B without resubmitting materials, reducing approval time from 3 days to 10 minutes, with a 60% approval rate increase; at the same time, data is encrypted and stored, allowing users to revoke authorization at any time, ensuring privacy and security.
2. Decentralized Value Flow Engine: From 'Third-Party Guarantee' to 'Intelligent Trust Voucher'
To reduce the trust cost of value flow, the engine generates 'Intelligent Trust Vouchers (ITV)' based on identity trust scores: high-scoring users (≥80 points) can use ITV instead of traditional collateral for cross-chain transfers and staking, without the need for third-party guarantees; users with lower scores have their collateral requirements reduced proportionally (e.g., a score of 60 reduces the collateral ratio from 150% to 120%). After integration with a certain cross-chain DEX, the guarantee cost for users' cross-chain transactions decreased from 2% to 0.3%, and the default rate dropped from 5% to 0.8%; ITV synchronizes changes in identity scores in real-time, and score improvements can automatically reduce collateral, providing flexibility far beyond fixed guarantee models.
3. Commercialization Implementation: The Practical Value of Trusted Flow
In the cross-border credit scenario, a certain bank directly trusts the user’s identity score from three financial Rollups on Caldera based on a unified identity trust network, improving cross-border credit approval efficiency by 90% and reducing bad debt rates by 75%; the decentralized engine saves the bank from third-party guarantee fees, reducing annual costs by 1.2 percentage points. In the supply chain collaboration scenario, suppliers with high identity scores obtain collateral-free cross-chain settlement qualifications, reducing settlement cycles from 15 days to 1 day, increasing capital turnover by 14 times, and enhancing overall supply chain efficiency by 60%.
In summary, Caldera's innovation directly addresses the core of 'trust' in commercial collaboration. By unifying identity and decentralizing flow, Layer2 truly possesses the capability to support high-trust demand scenarios, providing a trusted foundation for the integration of Web3 and the real economy.
