Flare is preparing to extend its data verification infrastructure beyond its own ecosystem through a new Decentralized Verifier Network (DVN) for LayerZero, introducing a proof-of-stake-based option for securing cross-chain messages.
Announced Nov. 12 in Dubai, the integration will bring Flare’s network-backed verification system into LayerZero’s messaging infrastructure. The DVN will draw on 100 independent data providers, which reach consensus on information from source blockchains before a verification result can be submitted to the destination chain.
Under the proposed model, a message is confirmed when data providers representing a majority of the network’s stake weight agree on the result. The providers sign a Merkle root containing the accepted results, which is relayed to Flare’s Relay contract on the destination chain. The DVN then checks the message proof against that root before casting its verification vote in LayerZero.
“Interoperability is only as strong as the infrastructure securing the information that moves across chains. With the Flare DVN, we’re bringing the security of an entire network of data providers into LayerZero’s verification ecosystem. This is an important milestone for Flare because it marks our evolution from using interoperability infrastructure to actively contributing to its security. For the first time, the data infrastructure securing Flare and FAssets can also help secure value beyond our own ecosystem,” said Hugo Philion, co-founder and CEO of Flare.
The design differs from verification systems that rely on a single operator. Flare said its DVN uses multiple independent data providers to establish consensus, while proof delivery remains permissionless, allowing anyone to relay the verification result to the destination chain. Flare also operates multiple independent operators to support network liveness and redundancy.
The new verifier will join LayerZero’s existing DVN ecosystem as an additional option rather than a replacement for other providers. Under LayerZero’s model, asset issuers select which DVNs must verify messages and how many must agree before a transfer is completed. Issuers using the OFT Standard include Tether, PayPal, Paxos, Ondo and Anchorage Digital.
Flare’s implementation builds on three components of its existing data infrastructure: the Flare Data Connector (FDC), Relay and a dedicated verifier contract. FDC enables network-level consensus on external blockchain data, while Relay makes FDC-attested information verifiable across supported Ethereum Virtual Machine chains through roots jointly signed by Flare’s data providers.
The verifier contract checks each packet against FDC-attested source-chain data before validating the source chain, LayerZero endpoint and minimum confirmation requirements for a verification vote. The DVN’s smart contracts were audited by OpenZeppelin in a report dated September 2026. Flare said the audit reported no critical, high or medium severity findings.
The planned integration is part of Flare’s effort to extend its data infrastructure into applications beyond its own network. The company’s existing stack supports external data verification and its FAssets system, while the LayerZero deployment would apply the same infrastructure to cross-chain message verification.
Flare is targeting a December 2026 launch, subject to final coordination. The company said it plans to release technical documentation, developer resources and further details about the DVN’s verification architecture ahead of ecosystem adoption.
