安全视角洞悉EigenLayer生态
摘要
1. EigenLayer的核心技术再质押Restaking允许去中心化服务（AVS）重用以太坊的质押资金池并增强信任机制。当ETH验证者的取款凭证被重定向至 EigenLayer 合约后，AVS 可以设定奖惩机制吸引低成本的验证参与，提高验证者的资金利用率并增强整体网络安全。
2. EigenLayer在“共识贩卖市场”中引入了新的微观和宏观安全挑战。市场的主体：ETH验证者（Operator），需求去中心化PoS信任的服务项目（AVS），以及EigenLayer平台本身，构成了生态系统中的互动结构。其中每个部分都可能面临安全威胁，影响整个生态系统的稳定性。恶意Operator可能在Restaking机制下以较低的成本对多个服务进行攻击；恶意AVS可能会利用表面宣传和看似可信的回报率吸引不明真相的Operator加入其服务体系，使其遭受slashing和不可逆的损失；快速发展的生态向EigenLayer协议的安全性提出了更高的要求。
3. 专业的审计和可靠的动态保护措施是保证平台和用户安全的基石。EigenLayer生态除了创新外还需要能够应对新挑战的强大安全框架。BlockSec在区块链安全领域持续build，为项目方提供专业的代码审计以及上线后的动态安全保护，支持这一生态系统的持续成长。
引言
基于以太坊的协议EigenLayer创新性地提出再质押功能，允许参与者能够在保持原有质押和收益的同时，进一步利用其质押的ETH来支持其他协议，从而最大化资本的潜在价值。
从2024年初的10亿美元增长至现在的153亿美元，EigenLayer的TVL在整个DeFi生态里仅次于Lido。爆发式的增长不仅展示了市场的强烈兴趣，也验证了其技术的实用性和影响力。随着这种增长，基于EigenLayer生态的项目如Puffer Finance和Renzo等也迅速获得了资本和用户的青睐。以EigenLayer为核心的再质押赛道无疑是今年DeFi生态中最受瞩目的叙事之一。
作为一家专注于区块链安全的公司，我们将从宏观到微观的安全角度分析与探讨EigenLayer的运行机制在创新DeFi生态的同时，带来了什么新的安全挑战和考验。
顶层设计与宏观安全
Restaking本质是一种通过重用以太坊Proof of Stake (PoS)质押资金池提供的信任来进一步解决特定问题的基础手段。EigenLayer作为Restaking技术的奠基者，向一个新兴的市场提供双向自由的以太坊资金池信任的贩卖，即提供了一个共识的贩卖市场。EigenLayer宣称现在的以太坊生态正在遭受信任分裂的宏观安全问题，而EigenLayer可以很好的解决这个问题。接下来我们就从EigenLayer的设计和动机出发，了解什么是信任分裂，以及EigenLayer是如何解决信任分裂的。
1. 共识贩卖市场的服务对象是谁？双向自由涉及的双方是谁？
EigenLayer贩卖的是以太坊Ethereum的质押资金池提供的信任，所以共识的卖方就是以太坊的验证节点Validator。而买方，即主动验证服务，Actively Validated Services（AVSs）。简单来说，可以理解为一个个任意需要构建分布式信任网络的服务，AVS作为买方，他们的需求是购买分布式信任。
2. 这个新兴的细分市场为什么需要存在？解决了什么问题？
以太坊仅仅提供合约层面的创新性质。而开发者有着更“深层次”的创新需求，例如试图修改程序的运行环境（在以太坊就是Ethereum Virtual Machine EVM），或者更进一步的希望修改共识协议。

EigenLayer的创始人将这些开发者对底层创新的渴望视为一个未被满足的市场需求，视为一个创新受限的问题并试图通过提供重用以太坊信任的自由贩卖市场来解决这个创新受限问题，满足开发者的创新需求，降低创新成本。

Re-pledge, the core technology, allows decentralized services to reuse the pledged fund pool of Ethereum and enhance the trust mechanism. When the withdrawal voucher of the verifier is redirected to the contract, a reward and punishment mechanism can be set up to attract low-cost verifiers to participate in improving the utilization rate of funds and enhance the overall network security. In the consensus selling market, new micro and macro security challenges have been introduced, and the main body of the market, the service items that the verifier needs to decentralize and trust and the platform itself constitute the interaction in the ecosystem. Each part of the structure may face security threats, affecting the stability of the whole ecosystem. Malicious may attack multiple services at a lower cost under the mechanism. Malicious may use superficial propaganda and seemingly credible return rate to attract unknown facts to join its service system, causing them to suffer and irreversible losses. The rapidly developing ecology puts higher demands on the security of the protocol. Professional auditing and reliable dynamic protection measures are the cornerstones to ensure the safety of the platform and users. In addition to innovation, we need a strong security framework that can cope with new challenges. In the field of blockchain security, we will continue to provide professional code auditing and dynamic security protection support for the project. Introduction The protocol based on Ethereum innovatively puts forward the re-pledge function, allowing participants to further use their pledges to support other agreements while maintaining the original pledges and benefits, so as to maximize the potential value of capital from $ billion at the beginning of the year to $ billion now. The explosive growth of the US dollar in the whole ecology not only shows the strong interest of the market, but also verifies the practicability and influence of its technology. With this growth, eco-based projects such as Hehe have quickly gained the favor of capital and users. The re-pledge track with the core is undoubtedly one of the most eye-catching narratives in this year's ecology. As a company focusing on blockchain security, we will analyze and discuss the operating mechanism from the macro-to-micro security perspective, while innovating the ecology. What are the new security challenges and tests? The essence of top-level design and macro-security is a basic means to further solve specific problems by reusing the trust provided by the fund pool pledged by Ethereum. As the founder of technology, it provides a two-way freedom to an emerging market. The selling market claims that the current Ethereum ecology is suffering from the macro-security problem of trust split, which can be well solved. Next, we will set up from. Considering the motivation, we can understand what trust split is and how to solve it. Who is the service target of the selling market? Who are the two parties involved in two-way freedom? Who sells the trust provided by the pledged fund pool of Ethereum, so the seller of consensus is the verification node of Ethereum, and the buyer is the active verification service. Simply speaking, it can be understood as one service that needs to build a distributed trust network at will. As a buyer, their demand is to buy distributed trust, a new market segment. What needs exist and what problems have been solved? Ethereum only provides innovative nature at the contract level, while developers have deeper innovative needs, such as trying to modify the running environment of the program. In Ethereum, the founders of the consensus agreement regard these developers' desire for bottom-level innovation as an unmet market demand and try to solve this problem by providing a free selling market that reuses Ethereum's trust. The topic meets the innovation needs of developers, reduces the cost of innovation, and also deals with the macro-security problems caused by limited innovation in Ethereum.
