According to Cointelegraph, the teams behind Ethereum re-staking protocol EigenLayer and cross-chain messaging protocol LayerZero have introduced a new system aimed at enhancing the security of cross-chain communication. In a blog post on Oct. 2, LayerZero Labs announced their partnership with Eigen Labs and unveiled a framework for 'CryptoEconomic Decentralized Verifier Networks' (DVNs).
The newly introduced system combines technical verification with financial incentives to ensure secure cross-chain messaging. It addresses several issues related to cross-chain security, such as the lack of economic incentives to ensure trust, limited participation in security, and inflexibility in security models. DVNs leverage cryptoeconomic security, where verifiers stake assets that can be taken away or 'slashed' if they act dishonestly or make mistakes.
The system operates through four primary mechanisms to ensure cross-chain communication security. Verifiers lock up or stake assets like ETH or other tokens such as the protocol’s native assets EIGEN or ZRO as collateral. Messages are then sent and verified across blockchains. If a discrepancy is found, tokenholders can vote on whether to veto the staked assets. Finally, if malicious behavior is confirmed, the staked assets are taken away or slashed.
The benefits of the system include increased security for cross-chain messaging, financial incentives for honest behavior, inclusion of any network to contribute by staking assets, and flexibility with various verification methods. The framework is open source, allowing other teams to launch their own DVNs using their preferred assets to stake, enabling application-specific DVNs with customizable security parameters.
Eigen Labs explained that previously, the security of verifying omnichannel messages was solely based on the network’s verification mechanisms. However, with Eigenlayer’s re-staking primitive, anyone can stake their assets to provide an extra layer of security. Interoperability protocol LayerZero serves as a marketplace for DVN verifiers, with 35 entities currently participating, including zk-proof-based teams like Polyhedra, multi-bridge attestations from Hashi, and oracles like Google Cloud.
LayerZero Labs concluded that as this framework is adopted, the future of blockchain communication will be defined by trust, transparency, and accountability, bringing us closer to a world where every message across blockchains is secured by cryptoeconomics. EigenLayer currently has $10.8 billion in total value locked; however, according to DeFiLlama, that figure has fallen by almost 50% over the past four months.
