🥩 Staking Staking
Lock up your coins on a blockchain for a set period, help keep the network running, and earn rewards for doing so. Used on Proof-of-Stake (PoS) coins.
🏦 The simple version — a deposit-backed worker
A blockchain needs validators to check and record every transaction. But how do you stop a bad actor from joining and writing false records? The solution: every validator must post a security deposit in coins. Do the job honestly and you earn rewards. Cheat and your deposit gets cut. This is staking. If you don't want to run a validator yourself, you can delegate your coins to an existing validator and split the rewards — no technical setup needed.
🔗 Why is staking only for PoS coins?
Different blockchains have different ways of agreeing on what's true. Bitcoin uses a computing power race called Proof-of-Work (PoW). Ethereum and other Proof-of-Stake (PoS) blockchains pick validators based on how many coins they've staked. That's why staking only exists on PoS networks.
💰 Where do the rewards come from?
| Source | How it works |
|---|---|
| 🆕 Newly minted coins | The network creates new coins and distributes them to validators who contributed |
| 🧾 Transaction fees | A share of the fees users paid for their transactions goes to validators |
📊 Reward rates vary by coin and are not fixed. Any figure like "earn X% per year" is an estimate, not a guarantee — market conditions change it constantly.
🚨 Things beginners should know
- 📉 Price risk — Even if you earn rewards, a falling coin price can leave you with less in dollar terms
- ⏳ Unbonding period — You often can't withdraw immediately; some coins have a cooldown of days or even weeks
- ✂️ Slashing — If your validator misbehaves, a portion of your staked coins can be slashed (taken away)
- 🚫 Beware absurd yields — Promises like "1% per day" or "principal guaranteed" are almost always scams
❓ FAQ
- Is staking like free interest — does money just appear?
- Not quite. You earn rewards because your coins are helping run the blockchain — it's payment for a service, not free money. The rewards are paid in coins, and if that coin's price drops, you can still end up with less in dollar terms.
- Can I take my staked coins back whenever I want?
- It depends on the coin. Many have an "unbonding" or "cooldown" period of several days to a few weeks. During that time you can't sell or move the coins.
- Can I lose money by staking?
- Yes. The coin's price can fall even while you're earning rewards. There's also slashing — if the validator breaks the rules, a portion of the staked coins can be cut. And any service promising unusually high fixed yields should be treated with serious suspicion, as it may be a scam.
