What is staking?

Beginner · Mining and Staking · about 5 min read

Staking means locking up crypto to help a network run, and being rewarded for it. It is the main alternative to mining.

How it works

• On a proof-of-stake network such as Ethereum, validators check transactions and add new blocks. To become a validator, you put up coins as a deposit, called a stake.
• Honest work earns rewards. A validator that goes offline misses rewards and loses small amounts. One that provably cheats, for example by signing two conflicting blocks, is slashed: part of its stake is taken and it is removed.
• Ethereum needs at least 32 ETH to run your own validator. Ethereum moved from mining to staking in September 2022, and withdrawals of staked ETH began in April 2023.

Ways to stake

• On your own: you run the software and keep your own keys. On Ethereum this needs 32 ETH.
• Through a pool: you can stake smaller amounts and may get a token back that stands for your stake. This adds the risk of the pool’s smart contract failing.
• Through an exchange: easiest, but the exchange holds your coins. Ethereum’s own guide calls this the option that needs the most trust.

Keep in mind

• Rewards are not guaranteed, and the coin’s price can fall by more than you earn.
• Joining or leaving can involve a waiting line that lasts anywhere from hours to weeks.
• Rules for businesses that hold crypto for other people are covered in Is crypto legal in Trinidad and Tobago?
• General information, not financial advice.

What you earn and what it costs

Staking rewards come from the network, for honest work that keeps blocks being produced and checked. They are paid in the same coin you stake, so the value of what you earn rises or falls with the coin's price. A simple example with made-up numbers: you stake 10 coins worth $100 each ($1,000) and earn 4 percent, or 0.4 coins. If the price then falls 10 percent to $90, your 10.4 coins are worth $936, which is a loss of 6.4 percent even though the reward arrived. Rewards do not protect you from price risk.

What you trust in each method

Ethereum's staking guide lays out the risks of each way of taking part:

• Home staking. Your coins are at risk of penalties if your computer goes offline and of slashing if you break the rules. Creating a receipt token adds smart contract risk. You trust yourself and your setup.
• Pools and liquid staking. The guide names counterparty risk, meaning the pool's operators, and execution risk, meaning the pool's smart contracts. The receipt token's value depends on the pool. You trust a group and its code.
• Exchanges. The exchange holds your coins, so you rely on its custody practices. The guide also notes that large amounts of stake in one place create a single point of failure for the network. You trust a company.

Why the 32 coin figure is not the whole story

The guide says running your own validator on Ethereum takes at least 32 ETH, and that since the Pectra upgrade one validator can hold up to 2,048 ETH. Other proof-of-stake networks set their own minimums, reward rates and waiting times, so read the network's own guidance before locking up anything.

Offers that sound too good

The FTC lists guaranteed profits, big or fast returns and "zero risk" as warning signs of a scam. A staking page that advertises a fixed high yield should prompt a simple question: where does the return come from? Network rewards are limited. A return far above them usually means someone is lending your coins or taking another risk with them. In Trinidad and Tobago, a business that holds crypto for other people falls under the 2025 law, which temporarily prohibits virtual asset business until 31 December 2026 unless the business is approved by the TTSEC, so ask for proof of approval.

Common mistakes

• Counting the percentage reward while ignoring a fall in the coin's price.
• Locking up coins you may need soon, then facing a waiting line to get them out.
• Treating a receipt token as if it were the same as the original coin.
• Staking through a site found in an advert or a direct message.
• Assuming staking through an exchange is the same as holding the coin yourself.

Try it yourself

1. Read the staking page on ethereum.org and write one line each on home, pool and exchange staking: who holds the coins, and what could go wrong.
2. Repeat the worked example with different numbers: a 5 percent reward and a 20 percent price fall. Is the result a gain or a loss?
3. Pick one staking offer you have seen online and write two questions you would need answered before trusting it.
