From Validators to LSDs: The Evolution of Ethereum Staking

Ethereum’s shift to Proof-of-Stake (PoS) marked a fundamental change in how the network operates — and how users participate. Over time, staking has evolved from a technical task reserved for node operators to a core building block of DeFi, thanks to the rise of liquid staking protocols. This article outlines the key stages of that evolution.

1. Native staking: 32 ETH and solo validators

At its core, Ethereum’s PoS requires validators to lock 32 ETH and run dedicated software to propose and attest to blocks. This model is decentralized and secure but comes with high capital and technical requirements, making it inaccessible for most retail users.

2. Staking pools: lowering the entry barrier

To solve the accessibility issue, staking pools emerged. They allow users to stake less than 32 ETH by pooling funds and sharing rewards. Centralized exchanges (CEXs) like Coinbase and Binance were early movers, but their models introduced custodial risk and reduced user control.

3. Liquid staking: unlocking liquidity

Liquid staking protocols like Lido and Rocket Pool solved two problems: accessibility and illiquidity. By issuing tokenized representations of staked ETH (e.g. stETH, rETH), users could:

• Stake any amount,
• Retain exposure to ETH yield,
• Use LSDs in DeFi protocols (as collateral, in LPs, etc.).

This model significantly increased staking participation and integrated staked ETH into the broader DeFi ecosystem.

4. LSDs in DeFi: new use cases, new risks

The adoption of LSDs created a new subcategory — LSDfi. Protocols like Lybra, Pendle, and Curve began building on top of stETH and rETH, enabling users to:

• Earn additional yield on top of staking rewards,
• Trade interest rate derivatives,
• Leverage staked assets in multiple layers.

While powerful, this stacking of risk introduces potential vulnerabilities like depeg scenarios, liquidity crunches, and systemic loops.

5. What’s next: restaking and shared security

The next evolution is restaking, with protocols like EigenLayer allowing users to reuse their staked ETH (or LSDs) to secure additional networks or services. This could expand the utility of staked assets but also adds complexity and risk to Ethereum’s trust model.

Conclusion

Ethereum staking has gone from technical infrastructure to financial primitive. LSDs have redefined how users interact with ETH and opened up a new layer of composability in DeFi. The challenge now is balancing utility, decentralization, and systemic risk as the ecosystem continues to grow.
