LayerZero's V2 Upgrade: A Paradigm Shift in Blockchain Interoperability

Today, LayerZero, the protocol linking various blockchains, announced a major upgrade. The LayerZero V2 upgrade marks a substantial leap toward realizing a censorship-resistant, permissionless, and immutable blockchain communication protocol tailored for the dynamic Web3 landscape.

Elevating Interoperability Standards

LayerZero positions itself as a permissionless, censorship-resistant, and immutable omnichain interoperability protocol. Drawing parallels to the standard-setting role of TCP/IP in internet development, LayerZero aims to establish a unified approach to application development across diverse blockchain networks.
Since its establishment in 2021, LayerZero has facilitated the seamless transfer of over 85 million messages across more than 45 blockchains, cementing its position as a market leader in the blockchain arena.
Critical dApps in the crypto landscape, including JOE, CAKE, MIM, agEUR, BTC.b, PRIME, CANTO, and MAV, leverage the Omnichain Fungible Token (OFT) Standard. This standard allows fungible tokens to move across multiple blockchains without the need for asset wrapping, middlechains, or liquidity pools.

Key dApp Integrations

Several influential dApps, such as Radiant, Tapioca, Stargate, and Angle, have been built directly on LayerZero’s messaging protocol. This underscores LayerZero’s pivotal role in supporting crucial applications in the crypto space.

Modular Security: V2 introduces a self-custody feature for dApp developers. Application owners gain complete control over their "Security Stack" by selecting and combining diverse Decentralized Verifier Networks (DVNs).
Throughput: To ensure optimal speed, V2 adopts "lazy nonce-order enforcement," allowing the maximum throughput of the destination chain.
Liveness: V2 separates execution from verification, introducing the "Executor" as a permissionless role. This enables any participant to submit verified transactions directly to blockchains.
Unified Semantics: V2 enables developers to build applications that function uniformly across every blockchain connected through LayerZero.

Additional V2 Features

Easier Configuration: V2 empowers application owners to configure a custom Security Stack with required and optional DVNs. This addresses concerns raised in the V1 version.
Adapters: The V2 rollout includes adapters for third-party bridges, native bridges, and oracles, operating as DVNs within LayerZero. Adapters for Axelar and CCIP are introduced.
Horizontal Composability: V2 allows the stacking of transactions independently, achieving horizontal composability without freezing dApps, even if individual transactions fail within a bundle.

Insights into LayerZero Labs and Future Token Distribution

LayerZero Labs, the entity behind LayerZero, recently raised $120 million in a Series B funding round, valuing the company at $3 billion.

Co-founder and CEO Bryan Pellegrino, with a background in professional poker, entrepreneurship, and AI research, emphasized the importance of developers trusting themselves while building on LayerZero. The team plans to distribute tokens in the first half of 2024.
"If you're building on LayerZero, it's because you don’t want to trust others; it’s because you trust yourself."

"V2 is just an upgrade, making security easier to configure, increasing throughput, and minimizing liveness concerns through permissionless infrastructure roles," added Brian.
