In the current era of multi-chain parallelism, financial protocols often need to handle complex processes such as cross-chain collateral, clearing, and incentive distribution. However, ensuring the credibility of this cross-chain data has always been a challenge. Many projects rely on centralized or self-built oracles, which not only incur high costs but also bring trust risks.
Lagrange's SQL co-processor offers a brand new path. Developers only need to write a single SQL query to call the required data from different chains. The co-processor performs the computation off-chain and generates a zero-knowledge proof. On-chain contracts only need to verify this proof to confirm the authenticity of the results. This means that cross-chain financial operations can rely entirely on cryptographic guarantees instead of intermediaries.
Taking Frax/Fraxtal as an example, they use Lagrange's co-processor to transparently calculate the cross-chain incentive distribution of veFXS, allowing users to avoid concerns about human intervention. This model enables cross-chain financial protocols to achieve true openness and transparency, setting a new standard for the entire DeFi industry.
