Flare announced on Tuesday, August 27th, that the Polyhedra community has approved a proposal to integrate Flare with Polyhedra’s zkBridge DVN.
In a press release shared with Cryptowisser, the team said the integration will empower Flare developers to create secure and efficient cross-chain applications using LayerZero while benefiting from the cryptographic guarantees of ZK proofs.
Flare explained that zkBridge is a trustless, efficient, secure cross-chain interoperability protocol and one of LayerZero’s Decentralized Verifier Networks (DVNs). zkBridge supports more than 30 layer-1 and layer-2 networks and has verified over 20 million cross-chain transactions.
It utilizes zkSNARKs to enable a prover to efficiently convince the receiver chain that a certain state transition happened on the sender chain. zkBridge also offers strong liveness guarantees and robust bridging safety.
While commenting on this integration, Hugo Philion, Flare Co-founder, said, “Polyhedra’s zkBridge adds an additional security layer to LayerZero’s interoperability protocol and will be welcomed by Flare developers and users alike. Its integration is a sign of the growing support for Flare from cross-chain protocols and demonstrates the value of ZK technology in making it easier for value to flow freely between networks.”
Eric Vreeland, Chief Strategy Officer of Polyhedra, added that,
“We are excited that the Polyhedra community has voted to support the integration of Flare with zkBridge. The level of activity on Flare has been ramping up and reliable bridging protocols are the key to accelerating this while maintaining decentralization. We look forward to seeing how Flare developers utilize zkBridge to create dapps that draw data from a rich variety of multi-chain protocols.”
zkBridge leverages zkSNARKs to securely relay and verify block headers and consensus across different chains. It leverages a 2-layer recursive proof system to achieve fast proof generation and low on-chain proof verification cost to support cross-chain applications.
Polyhedra's zkLightClient technology reduces onchain verification costs and latency by efficiently batching multiple transaction verifications into a single proof.
Decentralized applications can obtain data from other networks using zkBridge, allowing them to create powerful cross-chain financial applications for DeFi, including trading, perps, prediction markets, and much more.
Integrating Polyhedra’s zkBridge adds a layer of security on top of the LayerZero messaging protocol while making it easier for data and assets to flow freely to Flare.
Flare is the blockchain for data: an EVM smart contract platform specifically designed to support data intensive use cases, including Machine Learning/AI, RWA tokenization, gaming, and social.
By giving developers trustless access to the broadest range of data and data proofs at scale and for minimal cost, Flare expands the utility of blockchain and supports the development of new and improved use cases.
Meanwhile, Polyhedra Network designs and develops scalable and efficient zero-knowledge proof protocols for large-scale ZKP systems with distributed computing networks. Its products include zkBridge, zkLightClient, and Expander, the world's fastest ZK prover. Polyhedra applies zero-knowledge technology to web2 and traditional financial (TradFi) sectors to improve security, privacy, and efficiency.
