Polyhedra Network is Building a ZK-Powered Cross-Chain Bridge on Polygon

Polyhedra Network, a Web3 infrastructure builder, is developing a cross-chain bridge powered by zero knowledge technology to deliver on its mission of building a value layer of the Internet.

In April, Polyhedra Network’s launched zkBridge Mainnet Alpha offering support for NFT transfer and message passing across more than 10 Layer 1 and Layer 2 blockchains, including Polygon, Ethereum, Binance Smart Chain, and Cosmos. In collaboration with Polygon Labs, Polyhedra will enable fully trustless and efficient interoperability based on zero-knowledge proofs between Polygon and other Layer-1 and Layer-2 networks, and the security is guaranteed by proving Ethereum full consensus in ZK.

ZkBridge is a trustless, efficient, secure and universal cross-chain interoperability protocol secured by zkSNARKs. This framework provides proofs that validate consensus on any given blockchain, helping synchronize consensus results with other blockchains and making data available across multiple platforms.

Polyhedra Network and implemented deVirgo, a novel distributed proof system to accelerate the proof generation, and recursive proofs to reduce the proof size and on-chain proof verification cost of zkBridge. Recently, the team succeeded in proving the Ethereum consensus involving over 20,000 validators signing a single block in 10 seconds, achieving proof generation speed that was 100 times faster than other systems running on identical hardware.

The Polygon 2.0 blueprint unveiled this summer is a vision for an infinitely scalable and interoperable multi-chain Polygon ecosystem. The collaboration with Polyhedra builds on that mission to create a Web3 space that feels and runs like a single blockchain space.

Together, we can build an equitable future for all through the mass adoption of Web3!
