Restaking and the Security Economy: How EigenLayer Changed Everything

Here's a thought experiment. Ethereum has spent years accumulating billions of dollars in staked ETH, with validators putting up collateral to secure the network. That security is expensive to build. It took years. And once a validator's ETH is staked to secure Ethereum, it just sits there, doing one job. What if it could do two? That's the question EigenLayer answered. And the answer is reshaping how crypto networks get built. But to understand why it matters, we need to start with how Ethereum security actually works. Welcome to Day 58 of 60-Days in Web3 series. If you want to follow along as I keep learning, building, and occasionally changing my mind about Web3, you can find the rest of this series on X, on Medium, on Future, and you can join the Web3ForHumans Telegram community to discuss these topics in plain language. How Ethereum security works When you stake ETH on Ethereum, you're putting up collateral and running a validator node. Your job is to honestly process and confirm
