Succinct Labs and Polygon Labs Develop Novel Zero-Knowledge Proof to Boost Network Security.
Summary:
Succinct Labs and Polygon Labs have co-developed a novel zero-knowledge (ZK) proof called a "pessimistic proof". Built on a ZK virtual machine, SP1, designed by Succinct Labs, the pessimistic proof ensures the security of the AggLayer network. Cross-chain security is also enhanced through these pessimistic proofs. The integration of SP1 with Rust and Plonky3 further aids ZK development and simplifies it for developers. Polygon Labs’ co-founder has begun to undertake a new ZK role, and open-source technology plays a key part in enhancing these developments.
A novel zero-knowledge (ZK) proof, known as a "pessimistic proof", has been jointly developed by Succinct Labs and Polygon Labs. The proof, based on SP1, a ZK virtual machine (zkVM) designed by Succinct Labs, acts as a security measure in the AggLayer network by preventing any individual chain from threatening others' deposits.
The functionalities of SP1's Pessimistic proofs were elaborated by a representative from Polygon during a discussion with Cointelegraph. He explained that the proof ensures cross-chain security through a truth verification mechanism, either by a ZK-proof or a consensus mechanism. He further highlighted that it inhibits any chain from experiencing an over-withdrawal of tokens, thanks to chain-level accounting. Even when non-ZK chains are supported by the AggLayer in the future, the design will continue to function as it does now.
As Polygon Labs co-founder Sandeep Nailwal gets ready to undertake a new ZK role, the cogs are already in motion for SP1’s integration with Rust and Plonky3. Plonky3 enables developers to create new proof systems and zkVMs while SP1, an open-source zkVM, simplifies ZK development. SP1 also facilitates the verification of the Standard Rust (or any LLVM-compiled language) execution, freeing developers from coding custom ZK circuits and considerably reducing ZK development times.
The future prospects involving SP1 and Plonky3 were further revealed by the Polygon representative. SP1 serves as a testament to the collective value of open-source technology. Succinct Labs exploited Plonky3's open-source trait to speed up SP1 development. Plonky3, created by Polygon Labs researchers, invites anyone to contribute to its ongoing innovation.
The implications of the AggLayer and ZK tech were further probed in a recent interview by Cointelegraph with Polygon co-founder Brendan Farmer. He described the AggLayer not just as “a decentralized protocol operated by staked nodes” but delved into the underlying principles of the “Aggregated Blockchains Thesis”. Farmer emphasized the critical role that financial privacy playing, a task eased by ZK tech, in the upcoming decades.
