Native staking: rewards, duties and losses
A validator helps Ethereum agree on its history. Staked ETH backs that work: useful participation can earn rewards, while missed or conflicting duties can cost ETH.
An Ethereum-first beginner lesson. All simulator inputs are fictional; no wallet, live rates or real funds. Other proof-of-stake chains have different rules.
01 · what the ETH is doing
Stake backs a validator’s duties
A validator runs software that checks blocks, votes on the chain and sometimes proposes a block. Solo staking requires at least 32 ETH to activate a validator, plus maintained hardware and connectivity. The 32 ETH in this example is an entry-sized position, not a claim that all validators have that exact balance.
The upside is participation rewards and direct control of your validator and withdrawal keys. The work and expense are yours too. Native staking does not issue the transferable pool claim explored in the liquid staking lesson.

02 · work through both outcomes
More ETH does not guarantee more dollars
Start with normal operation and settle the period. Then lower the ETH price: rewards can increase your ETH balance while the position loses dollar value. Compare stress and loss in the same panel to see the costs that can outweigh rewards.
Illustrative model · no live rates
Rewards and losses on the same balance sheet
Choose a scenario, then step through it. Each scenario resets the timeline. All rates, losses, prices and waiting steps here are fictional.
Model inputs: 32 ETH, 4% gross annual rate for 90 days, 100% uptime, $90 external operating cost. Offline penalty = 32 × 1% × 90/365 × offline fraction. Slashing loss 0% of principal. These are teaching formulas, not Ethereum’s penalty schedule.
Step 1 · In wallet
Start with 32 ETH. Nothing is staked yet.
Wallet: 32.0000 ETH
Committed or awaiting withdrawal: 0.0000 ETH
Waiting steps are schematic, not a countdown. This model freezes balances during exit; real rewards, penalties and settlement amounts can differ during the waiting process.
| Component | ETH |
|---|---|
| Starting ETH | 32.0000 |
| Earned reward | 0.0000 |
| Ordinary offline penalty | -0.0000 |
| Slashing loss | -0.0000 |
| ETH claim before external costs | 32.0000 |
| Operating cost, ETH equivalent at selected price | -0.0000 |
| Net ETH equivalent | 32.0000 |
Outcome after external operating cost · illustrative outcome, not yet received
+0.0000 ETH equivalent versus holding
Net value $64,000 · change from starting dollars $0 · difference from holding the original ETH at the same final price $0.
The $0 cost is paid externally; it is not deducted from the validator’s ETH claim. ETH-equivalent cost changes with the selected price.
Rewards come from consensus participation and, for proposers, execution-related income. Actual returns vary with network conditions, validator performance and block opportunities. The model’s simple annual rate compresses those sources; it is neither a quote nor a guarantee.
03 · distinguish the failure modes
Offline is different from slashable
Missing duties can mean missed rewards and ordinary penalties. Slashing is a separate response to specific conflicting validator actions, such as double proposals or conflicting attestations; it removes stake and forces exit. Accidentally running duplicate validator keys can create slashable behaviour. Ordinary downtime alone is not the same event.
A prolonged failure of the network to finalise can also trigger inactivity penalties. Correlated slashing can make loss more severe. The simulator’s single percentage loss illustrates principal risk; it does not reproduce Ethereum’s full penalty formulas or predict a maximum loss.

An exit request is not cash in your wallet
Exiting and receiving a withdrawal are separate stages. Native validator withdrawals are processed by the protocol; the lab’s receive button advances the illustration, not an on-chain claim transaction. Network queues and withdrawal processing affect when ETH becomes available. The lab uses a few manual states so that distinction stays visible; each click is not an Ethereum epoch or a promised number of days.
This model leaves out taxes, hardware purchase, transaction fees, compounding rules, validator balance types and changing rewards while exiting. Key compromise, client faults and operator mistakes also matter. Staking earns compensation for participation and exposure to these responsibilities, not a fixed deposit return.
