Eigenlayer propose a solution to the fractured trust on ETH's layer 2/ sidechains. Problem: In order to utilized the full trust of L1, L2s and sidechains need to deploy/prove (rollup) their apps on the EVM(Ethereum Virtual Machine). But that's not generally possible, such as data availability layers, oracles, new VMs, bridges and trusted execution environments. To build trust around those parts introduces new problems like: it's hard to build new decentralized trust networks; even it's built, the trust level will not be the same as L1/ETH/BTC; the new trust network will split away the value on the L1.
The idea of EigenLayer is to introduce a new layer between ETH and those problem modules. EigenLayer makes each one of these modules into a containers. ETH owner can stake their eth on one of these container to provide security and trust to it. In return, the container will payback in fees to those stakers. Basic structure as below:
Eth owner -- ETH main-net -----(restake to one of the container)---- EigenLayer ---(fees back to staker)--- Container(Modules needs trust/secruity)
View this from another aspect, it's like a open investment market for stakers to put their stakes on. I think this is very important, besides oracles, data availability is also a huge problem to a blockchain system without the involvement of another blockchain. And I have a lot of doubts for the storage solution like Arweave or Filecoin.
Although there are solutions like using zk proof of another chain's state to built trust towards that chain without any 3rd party involvement. But you still have to rely on the chain's own security/trust. To get everything done under the security of one chain is necessary for scaling up. (Targeting the problems EigenLayer propose to solve.) This also fits how I vision the decentralized future that only 1~3 main chains will dominant over 99% of the networks and traffics.
Honestly this sounds like a proof of stake and more modules version of co-mining to me, share some security resources of the main chain to the sidechain. It just makes sense.
Eigenlayer提出了解决ETH L2/侧链上分散的信任/安全问题的解决方案。现有的问题：为了充分利用L1的信任/安全性，L2和侧链需要在以太坊虚拟机(EVM)上部署/证明（rollup）其应用程序。但是这通常是不可能的，例如数据可用性（测试数据是不是真的安全地存放在L2上）、oracle、新的VM、桥 和 新的受信任的执行环境。在这些部分建立信任会引入新问题（最简单就是要发一条新链，不一定要新token），例如：很难建立新的去中心化信任网络；即使建立了，信任级别也远远赶不上L1/ETH/BTC；新的去中心信任网络将使L1上的价值/信任分裂。EigenLayer是在ETH和这些问题/模块之间引入一个新层。EigenLayer将每一个问题的模块都变成一个容器。ETH所有者可以在这些容器之一上押注他们的ETH，以为其提供安全性和信任度。作为回报，容器将向这些押注者支付费用。基本结构如下：
ETH所有者——ETH主网——（重新押注到一个容器）——EigenLayer——（回报费用到押注者）——容器（就是需要信任/安全性的模块）
从另一方面看，这就像一个开放的投资市场，供押注者对喜欢有潜力的模块进行押注，以获得回报。我认为这非常重要，除了预言机之外，数据可用性对于一个没有利用到其他区块链的 区块链系统 是一个巨大的问题。毕竟对于像Arweave或Filecoin这样的存储解决方案，我有很多疑虑。
虽然有其他解决方案，例如使用另一个链的zk证明状态来建立对该链的信任，而不需要任何第三方参与。但是仍然需要依赖该链的自身安全性/信任度。想要有效扩容，大部分的活都需要在一条链所形成的系统下解决。（其实就是EigenLayer提出要解决的那些问题）。这也符合我对去中心化未来的看法，即只有1~3条主链会占据99%的网络和流量。
老实说，这对我来说听起来像是一个 Proof of stake 和更模块化版的co-mining，共享主链的安全资源到侧链。相当符合主链扩容的直觉思路。
