Introduction
Web3's rapid evolution stems from its open-source and decentralized nature, fostering hypergrowth and scalability—often termed crypto composability. This modularity enables seamless integration or removal of stack components, driving unprecedented innovation. At its core lies blockchain transactions, where decentralized networks validate and vote on state transitions to achieve consensus.
While Bitcoin and others use Proof-of-Work (PoW), most blockchains now adopt Proof-of-Stake (PoS), leveraging economic incentives for security. Introduced in Peercoin’s 2012 whitepaper and refined by Tendermint BFT (2014), PoS reduces energy consumption and penalizes malicious actors via slashing.
PoS adoption has sparked ideas to maximize staking capital utility, such as enhancing liquidity for ecosystem security—ushering in liquid and restaking protocols.
Staking Design Overview
Native Staking
Staking involves depositing tokens into smart contracts to secure protocols and earn rewards. Native staking restricts capital to idle contracts, whereas advanced forms offer added utility.
Challenges:
- High hardware/ETH requirements (e.g., 32 ETH + 16GB RAM for Ethereum).
- Delegation via pools (e.g., Rocket Pool, Jito) lowers barriers but locks liquidity.
Liquid Staking
Liquid Staking Tokens (LSTs) like stETH or JitoSOL represent staked assets, enabling DeFi composability. Since 2020, LSTs have grown to $42.3B TVL**, dominated by Lido (60%) and Ethereum (85%). Solana’s LST ecosystem totals **~$4B, with Jito capturing 45%.
Restaking
Restaking extends a blockchain’s security to other chains, shared via protocols like Eigenlayer. It allows new chains (e.g., appchains) to bootstrap security using established networks like Ethereum or Solana.
Approaches:
- Native Restaking: Validators commit to restaking modules.
- Liquid Restaking: Protocols stake on users’ behalf, issuing Liquid Restaking Tokens (LRTs).
- Universal Restaking: Chain-agnostic pooling of diverse assets (e.g., SPL, ERC-20).
Early Adopters:
- Polkadot’s parachains, Avalanche subnets, and Cosmos’ Replicated Security.
- Eigenlayer (2023) introduced AVSs (Active Validation Services) for Ethereum.
Current State of Restaking
- TVL: $28.14B, led by Eigenlayer (60%) and Ethereum (80%).
- Top Protocols: Eigenlayer, Babylon, Symbiotic, and Karak (each >$1B TVL).
- Liquid Restaking: $15.62B (57% of restaking TVL), with EtherFi dominating (50%).
Solana’s Growth:
- Picasso Network’s vaults attracted 3,507 SOL ($729K).
- Total Solana restaking TVL: $371M, accelerated by Solayer and Jito.
Restaking on Solana
Solana’s high-throughput, low-cost architecture positions it for restaking expansion. Jito emerges as a key player, leveraging its MEV and staking expertise.
Jito: A Primer
Founded in 2021, Jito Labs specializes in Solana MEV infrastructure:
- Jito-Solana Client: Used by 93% of validators, distributing 2.5K SOL in MEV tips.
- JitoSOL: $3.14B TVL, 45% of Solana’s LST market.
- StakeNet: Validator scoring and质押分配.
Jito (Re)staking Protocol
Launched in July 2024, Jito’s hybrid multi-asset protocol comprises:
- Vault Program: Mints Vault Receipt Tokens (VRTs) for任何 SPL asset.
- Restaking Program: Manages Node Consensus Networks (NCNs) and operators.
Features:
- Configurable slashing conditions.
- Multi-asset support (e.g., SOL, JitoSOL).
- Modular delegation (DAO/multisig strategies).
Adoption:
- Switchboard: Enhances oracle security via Jito.
- Renzo: Launches ezSOL VRT for cross-chain rewards.
- Sonic: Integrates Jito for SVM L2 security.
Why Restake on Solana?
- Capital Efficiency: Lower fees vs. Ethereum.
- Growth Potential: SVM L2s/appchains need economic security.
- Competitive Edge: Jito’s MEV rewards and Solana’s speed.
Risks:
- Slashing: Concentrated质押 amplifies penalties.
- LRT Liquidity: Redemption delays (~4–5 days).
- Governance: Subjective faults require robust dispute resolution.
Competitive Landscape
- Solayer: $168M TVL, shared validator networks.
- Sanctum/Marinade: Potential LST-based rivals.
- Eigenlayer: Expanding to ERC-20s; could enter Solana long-term.
Use Cases for Jito (Re)staking
- Decentralized Solver Networks: MEV redistribution for DEXs.
- SVM L2s: Custom security for high-throughput chains.
- Orderflow Auctions: Fair transaction pricing.
Conclusion
Restaking mirrors AWS’s impact—outsourcing security to accelerate innovation. Solana’s ecosystem, driven by Jito’s infrastructure, is poised to lead this shift. While risks persist, Jito’s protocol offers a modular, efficient path for NCNs to harness Solana’s liquidity and speed.
