\*\*Intro ::\*\*EigenLayer introduced the idea of **restaking** — reusing staked ETH to secure other services. I wanted to explore this idea by building a simplified **restaking module** that allows validators to opt into extra services and earn rewards.

**Sections:**

1.  **What is Restaking?**
    
    *   Normal staking secures Ethereum.
        
    *   Restaking → reuse same stake to secure other protocols.
        
2.  **My Implementation**
    
    *   **Operator Registry** – tracks which validators joined.
        
    *   **Delegation Model** – stakers delegate to operators.
        
    *   **Slashing** – operators misbehaving lose restaked ETH.
        
3.  **Architecture**
    
    *   Users stake ETH → Register with RestakingContract → Operator opts into modules → Rewards distributed.
        
4.  **Code Snippet (RestakingModule.sol):**
    

    function slash(address operator, uint256 penalty) external onlyModule {
        stakedBalances[operator] -= penalty;
        emit Slashed(operator, penalty);
    }
    

1.  **Lessons Learned**
    
    *   Restaking boosts security but introduces correlated slashing risk.
        
    *   Operators need strong monitoring.
        

\*\*Closing:\*\*My prototype shows how restaking can **extend Ethereum’s security** to other apps. It’s early, but this model could unlock a huge ecosystem of shared security.
