Traditional multi-sign bridges are 'trust me'; ZK light clients are 'don't trust me, trust the math.' Succinct has laid out two paths in this area: 🧐
Telepathy: A protocol for cross-chain messaging using Ethereum light clients securely. Developers can send messages from Ethereum to other chains without trusting centralized intermediaries or permissioned multi-signs.
Light client implementation: As early as 2023, Gnosis announced that the OmniBridge mainnet launch introduced Succinct's Ethereum ZK light client as a security upgrade, providing 'ZK consensus proof' level guarantees for over $40M TVL and >$1.5B stablecoin flow.
The core of this road's project is to bring over the 'consensus of another chain' for low-cost verification. The approach is to efficiently generate the 'block header/consensus proof' off-chain through SP1, and then put the 'verified summary/state' on-chain for the bridge/message layer to consume. a16z also repeatedly emphasizes: a bridge based on light clients can avoid an entire category of attack vectors because it turns 'trust multi-sign' into 'verify consensus.'
Why combine with Prover Network? Because the 'daily' of light clients is actually to continuously and rhythmically produce proofs (new blocks, window periods, challenge periods...). Handing over these types of 'regular orders' to a decentralized proof network, rather than a single-point data center, can be more stable in terms of cost, activity, and fault tolerance.
In fact, cross-chain is an industry of 'bringing over someone else's truth.' With ZK light clients, you don't have to gamble on trust; you just need to align with mathematics.
