Delegation

How delegation works in PoS

In a typical proof-of-stake network:

• A user holds tokens but doesn't want to run a validator themselves (which requires technical knowledge, server uptime, and minimum stake amounts).
• They delegate their tokens to a validator who already operates infrastructure.
• The validator includes the delegated tokens in its effective stake when proposing or attesting to blocks.
• Rewards are split: the validator takes a commission (typically 5-10%); the rest accrues to the delegator.
• The delegator retains custody — tokens never leave their control. Delegation is a signing relationship, not a transfer.

If the validator misbehaves and gets slashed, delegators typically suffer proportional losses on the delegated tokens. So validator selection matters even though tokens stay in the user's custody.

Major delegation networks

Most large PoS networks support delegation:

• Cosmos chains — delegated PoS is the default model. Validators publish commission rates; delegators choose where to delegate.
• Solana — non-custodial delegation through stake accounts.
• Cardano — pool-based delegation where users delegate to stake pools.
• Polkadot — nominators back validators.
• Avalanche — delegators can delegate to a validator; minimum delegation is 25 AVAX.

Ethereum doesn't support direct delegation in the protocol — running an Ethereum validator requires 32 ETH and operating a node. Most ETH staking happens through liquid staking protocols (Lido, Rocket Pool) that abstract delegation through token-issuing intermediaries.

DAO governance delegation

A separate use of delegation: DAO governance.

In token-based governance, holders can delegate their voting power to other addresses without transferring the tokens. The delegate can then vote on behalf of the underlying tokens.

This addresses a real problem in DAO governance: most token holders don't want to monitor proposals, read documentation, and vote on every issue. They'd rather defer to someone with relevant expertise. Delegation lets them stay engaged in governance through an intermediary.

Major DAOs (Uniswap, Aave, Optimism) have ecosystems of delegates — community members who publish their voting positions and receive delegated voting power based on the trust they earn. Some delegates have voting power exceeding billions of dollars worth of tokens.

How to choose a delegate

Common considerations for both staking and governance:

• Track record — uptime for validators; participation history for governance delegates.
• Commission / fees — staking validators charge commissions; governance delegates typically don't but may have implicit alignments.
• Decentralization — over-delegation to a single validator or delegate concentrates risk and influence. Most networks publicly track stake distribution and encourage spreading delegations.
• Alignment — for governance, find delegates whose values and policy positions match yours. Most major delegates publish position papers.

The Lido concentration debate

Lido, Ethereum's largest liquid staking protocol, controls roughly a quarter of all staked ETH (the percentage has fluctuated as the staking landscape evolves). This has triggered ongoing debate about whether Lido is too concentrated:

• Concern — if any single entity controls 33%+ of stake, they could potentially censor transactions or influence consensus. Lido approaching this threshold has been called a structural risk.
• Counter — Lido's stake is operated by 30+ independent node operators, not by Lido as a single entity. The DAO governance distributes operator selection.

The debate continues. Several alternative liquid-staking and restaking protocols have emerged partly in response, with Ethereum's broader ecosystem nudging delegators toward smaller protocols when possible.

Practical patterns

How most delegators actually behave:

• Set and forget — pick a validator, delegate, ignore for months or years. The most common pattern; works fine for the average case but doesn't catch validator misbehavior quickly.
• Multi-validator — split stake across several validators to limit single-point failures.
• Active monitoring — track validator performance; redelegate if performance degrades. Most useful for large delegators.

The combination of liquid staking and DAO delegation has expanded what "delegation" means well beyond its original PoS-only meaning. The general pattern — keep custody, route economic effect through an intermediary — is now used across most layers of the crypto stack.
