Centralized systems are prone to data manipulation, recording all data on-chain creates cost and scalability issues, and securely integrating off-chain data (such as AI results) with the chain is also a challenge. To address the above issues, Repai's improvements are as follows
On-chain recording of key reputation metrics
Final reputation scores, ratings, milestone events, etc. are transparently recorded in a BEP-20 smart contract, which can be viewed and tracked by anyone.
Issuance of verifiable reputation certificates (VCs)
Like Orange Protocol, VCs can be issued with the rationale behind the reputation calculation, allowing users to prove and utilize their reputation off-chain without incurring gas fees.
On-chain-off-chain integration
Off-chain AI results are reflected on-chain through a multisig or DAO-controlled oracle, with consideration for gradually leveraging decentralized oracle networks.
Efficiency and scalability
Manage data size and cost by storing detailed data in distributed storage such as IPFS and recording only hash values on-chain, or consider utilizing L2 solutions.
Ensure system reliability and integrity by preventing oracle manipulation, applying smart contract security patterns (Checks-Effects-Interactions) and access controls, and overflow checks.
