In the cross-chain field, heavy solutions like L0 and Wormhole must rely on relayers and oracles. Across V4, armed with a ZK+intent system implemented by Succinct, is the ideal solution for shattering additional trust assumptions. The key lies in the ZK capabilities provided by Succinct, which generates ZK proofs after listening to on-chain states, and can be verified by smart contracts on any target chain without additional deployment or trust intermediaries. In terms of universality, there's no need to write separate logic for different chains; a single deployment can be universal. In cross-chain verification and settlement, trust assumptions and challenge time windows are no longer necessary. Efficient, universal, and minimizing trust, Succinct has become the heart of this system. It provides a way for the target chain to truly "understand what happened on the source chain". In current mainstream solutions, you must trust that these relayers/oracles will not act maliciously or make mistakes. Although many large cross-chain protocols have their own "methods", such as having key roles operated by well-known institutions or setting multiple key roles to balance each other, this problem is largely similar to the Blockchain Trilemma, a trade-off between "efficiency" and "trust". @SuccinctLabs @AcrossProtocol
