What is Restaking?
Restaking is a mechanism in decentralized finance (DeFi) that allows users to extend the utility of their assets by securing multiple networks and services simultaneously. By building on Ethereum's crypto-economic security model, restaking protocols enable users to delegate their assets—such as ETH, Liquid Staking Tokens (LSTs), stablecoins, BTC derivatives, or other assets—to support validation across various layers of decentralized infrastructure.
Participants and Processes
Restakers:
Individuals or entities holding digital assets who delegate them to restaking protocols. Restakers earn additional rewards by contributing to the security of multiple networks and services.
Restaking Protocols:
Platforms like EigenLayer or Symbiotic facilitate restaking by connecting restakers to Validation Services and node operators, ensuring a seamless and efficient process.
Node Operators:
These entities maintain the technical infrastructure, running validator nodes that secure Validation Services and ensuring the stability of the network.
Restaking Curators:
Specialized entities that optimize restaking strategies, selecting and managing which Validation Services are supported based on security, profitability, and market conditions.
How does Restaking Work?
Restaking operates as a layered system that integrates crypto-economic security and additional yield generation:
Staking and Restaking:
Users stake assets, such as ETH or LSTs, on a native blockchain or a liquid staking protocol. These assets are then restaked through a restaking protocol like InceptionLRT to secure additional services.
Delegation to Validation Services:
Restaked assets are allocated to Validation Services that require extra security layers. Examples include data availability services, oracle networks, and Layer 2 protocols.
Dual-Layer Rewards:
Restakers earn native staking rewards (e.g., Ethereum’s Proof-of-Stake) and additional rewards generated through the restaking process, such as Validation Services fees or DeFi yield.
Yield and Security Optimization:
Curators and protocols craft strategies to maximize returns while ensuring robust security for supported services.
Why Does Restaking Matter?
Cryptoeconomic security is the backbone of decentralized networks, ensuring trust and stability through assets that act as economic collateral against malicious behavior. Restaking extends this concept by enabling assets to secure not just one network but multiple layers and services.
Key Advantages:
Strengthening Emerging Protocols:
New protocols often face challenges in establishing economic security. Restaking provides them with access to a pool of assets already secured by Ethereum or other networks, reducing the cost of launching and maintaining decentralized applications.
2. Enhanced Network Resilience:
Delegating cryptoeconomic security diversifies the risk of attacks across multiple layers, thereby strengthening the overall ecosystem. This layered security model allows protocols to allocate resources more efficiently while preserving their integrity.
3. Capital Efficiency and Flexibility:
Restaking enables users to optimize their assets, earning rewards from multiple networks without locking additional funds. This improves liquidity and maximizes the earning potential of the assets.
