The Polyhedra community has approved a proposal to integrate Flare with Polyhedra’s ZkBridge DVN (decentralized verifier network).
This integration will empower Flare developers to create secure and efficient cross-chain applications using LayerZero while benefiting from the cryptographic guarantees of ZK (zero knowledge) proofs.
ZkBridge is a trustless, efficient and secure cross-chain interoperability protocol and one of LayerZero’s DVNs.
It supports more than 30 layer one and layer two networks and has successfully verified more than 20 million cross-chain transactions.
ZkBridge uses ZkSNARKs to enable a prover to efficiently convince the receiver chain that a certain state transition happened on the sender chain.
In addition to robust bridging safety, enabled by ZK proofs, ZkBridge offers strong liveness guarantees since only one honest member of the validator set is required for bridging.
Hugo Philion, co-founder of Flare, 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, said,
“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 utilizes ZkSNARKs to securely relay and verify block headers and consensus across different chains.
It uses a two-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, in particular, dramatically reduces on-chain verification costs and latency by allowing for the efficient batching of multiple transaction verifications into a single proof.
On-chain light clients allow for the source chain’s validator set to attest to an event that occurred on their chain to a destination chain.
DApps deployed on Flare, for…
