祝贺EigenLayer团队正式推出EigenCloud！从多方面来看，这堪称是链上与链下计算范式完美融合的圣杯。本文将具体研究其核心要义，让我们一探究竟。
区块链的核心能力在于验证并确保计算正确性，但该能力仅适用于链上信息。一旦涉及链下数据，信任模型即告失效，必须依赖预言机将极其有限的信息上链。这种模式虽能支撑稳定币、DeFi、NFT等部分应用，但在需要对接现实世界的复杂场景中就会捉襟见肘——这些场景往往需要调用标准库、发起API请求等典型的"Web2"开发操作。
EigenCloud允许开发者将丰富的应用逻辑迁移至可验证的链下容器，仅在链上保留最基础的共识强制逻辑，而将前端等无需验证的基础设施留在现有公有云中。代币逻辑始终驻留链上，应用逻辑则主要转移至链下（同时保持可验证性）。
可信API调用 -- 针对孤岛化Web2数据的API请求现在能直接触发链上代币逻辑。用户可证明其私有登录信息中的任何Web2数据特征，从而打破Web2数据孤岛，实现用户向区块链的无缝迁移。
自主AI代理 -- 依托区块链原生产权特性与EigenCloud的可编程能力，完全链上AI代理不再需要人类授权即可行动：它们可持有资产、缔结合约、承担债务甚至创建DAO。
企业合规保障 -- 将熟悉的云工具与区块链级审计追踪相结合，为企业提供可验证合规与结算的低摩擦路径。
EigenVerify确保计算过程正确性验证，EigenCompute则将整个EigenLayer生态封装为开发者友好型工具包。
容器化部署至EigenCompute：开发者创建容纳应用逻辑的容器，用于扩展任意区块链的代币逻辑。该容器随后部署至EigenCompute，该平台能简化合适质押者与运营节点的匹配流程。
EigenLayer保障计算安全：计算任务由EigenLayer运营节点集执行，并通过质押者专门为此应用分配的部分安全资本获得保障。附有签名证书的运算结果将传递至目标区块链。链上合约可选择立即调用这些具备独特经济安全性的结果，或等待挑战期结束后获取更高安全性（类似optimistic rollups）。
EigenDA实现数据可用性：计算数据记录至数据可用性层（DA），任何观察节点均可通过EigenDA独立验证计算过程。
EigenVerify挑战验证：若发起挑战，原始计算将通过EigenVerify服务进行验证——该服务专为验证目的重新执行计算。若初始节点组被判定为不良节点，其质押资产将被罚没（slash）并分配给应用方。
代币分叉保障EigenDA与EigenVerify：若保障EigenDA或EigenVerify的大部分EIGEN质押者行为不良导致流程污染，EIGEN代币将触发分叉。此举将罚没不良质押者与运营节点的质押资产，确保系统完整性而无需单纯依赖多数委员会的可信度。任何人通过销毁特定比例的原生EIGEN代币均可发起分叉，并获得更大量分叉后EIGEN代币作为奖励，由此确保存在充足的分叉触发激励。
应用/链分叉增强安全性：基于EigenCloud构建的应用、服务或链可选择预先承诺并与EIGEN代币同步分叉。这确保在正确分叉链上，应用与服务结果始终保持完整状态。
需要特别强调的是，这并非全新概念。诸多项目曾为其应用尝试过不同版本的类似方案，但均未获普及，究其根本是用户仍需对应用开发者保持绝对信任。EigenCloud是首个以服务形式提供该功能的尝试，目前已有超120亿美元质押资本为协议提供安全保障。
当下比任何时候都更需要可验证计算：它将推动全球资产上链，并向用户、监管机构及合作伙伴提供不可篡改的保证。再次祝贺EigenLayer团队发布此项成果，期待主网上线！
