Blockchains are isolated. Ethereum can’t talk to Arbitrum. Base can’t talk to Optimism. Each chain is its own world — its own state, its own rules, its own tokens.
If you have 100 USDC on Ethereum and want to use it on Arbitrum, there’s no built-in way to move it. The two chains don’t know each other exists.
LayerZero is the leading omnichain interoperability protocol, connecting 70+ blockchains with 130M+ cross-chain messages delivered. Backed by $263M from a16z and Sequoia at a $3B valuation, it has attracted 35,000+ developers and 50,000+ deployments. We conducted a full market + technical deep dive. Here’s what we found.
LayerZero V2 (launched 2024) was a major overhaul. The old Oracle+Relayer model — widely criticized for centralization — was replaced with Decentralized Verifier Networks (DVNs). The core Endpoint contracts are now immutable: no admin keys, no upgrades, no governance attacks.
LayerZero 是领先的全链互操作协议，连接 70+ 条区块链，已传递超过 1.3 亿条跨链消息。获得 a16z 和红杉资本 2.63 亿美元投资，估值 30 亿美元，吸引了 35,000+ 开发者和 50,000+ 部署。我们进行了完整的市场和技术调研，以下是核心发现。
LayerZero V2（2024 年上线）是一次重大升级。被广泛批评为中心化的 Oracle+Relayer 模型被替换为去中心化验证者网络（DVN）。核心 Endpoint 合约现在是不可变的：没有管理员密钥，没有升级，没有治理攻击。
核心创新：每个应用选择自己的安全配置。你可以选择哪些 DVN 来验证消息 — Google Cloud DVN、Polyhedra ZK DVN，或者运行自己的。这与竞品的协议级统一安全模型有本质区别。
| 协议 | 链数 | 安全模型 | 优势 |
|---|---|---|---|
| LayerZero | 70+ | 应用可配置 DVN | 灵活性 + 覆盖范围 |
| Wormhole | 30+ | Guardian 多签 (13/19) | Solana 生态 |
| Chainlink CCIP | ~20 | Chainlink 预言机网络 | 机构信任 |
| Axelar | 50+ | dPoS 验证者 | Cosmos 生态 |
| Hyperlane | 35+ | 无许可 ISM | 可定制性 |
LayerZero 的护城河是最大的链覆盖范围、应用可配置安全性和不可变核心协议的组合。一旦协议在 LayerZero 上部署 OFT，切换成本很高。
