"Restaking" has recently appeared frequently in various protocols, with Symbiotic, Eigenlayer, Karak, etc., starting to compete for this big cake. "Follow for updates"
🧠 Simple explanation:
Use the assets you have already staked to protect other protocols and earn extra rewards.
It's like: you mortgaged your house to the bank for a loan, and you can also transfer the "loan contract" elsewhere to earn interest—sounds unreliable? Restaking aims to solve this problem with smart contracts in the crypto world.
🧪 Why is it hot now?
Eigenlayer: Allows you to "re-stake" ETH that is already staked on Ethereum to protect other networks, such as data availability layers, oracles, etc.
Symbiotic: Supports restaking of multiple assets and multiple uses, not limited to ETH.
📉 The risks are very real:
The validator penalty mechanism is vague;
Scam projects abusing restaking liquidity;
Higher security requirements ("one violation, multiple penalties").
Restaking is an important overlay of the Web3 security layer, but it is by no means just mindlessly grabbing airdrops or earning passively; what can truly develop long-term are protocols with clear mechanism design, rigorous security models, and the ability to accommodate real demand.
