Instead of spending electricity to compete, a proof-of-stake network asks participants to put capital at risk. A validator locks up a required amount of the coin as collateral, and the protocol then selects validators to propose and confirm blocks, often weighted by how much they have staked. Honest work earns a steady reward; provably dishonest behaviour can be punished by slashing, which destroys part of the stake. Ethereum moved to this model in 2022, cutting its energy use dramatically.
The security logic mirrors proof of work but swaps the scarce resource. Under proof of work an attacker needs overwhelming computing power; under proof of stake they would need to control a huge fraction of the staked coin and would risk having it slashed. In both cases the network makes attacks self-defeatingly expensive.
Proof of stake enables lower energy use and lets ordinary holders earn a yield by staking, sometimes through an exchange or pool. Those rewards are real but variable, lock-ups and slashing are genuine risks, and advertised rates are estimates, not promises. Crypto House explains staking as mechanics and never as guaranteed income. Because it lowers the hardware barrier, proof of stake also lets far more ordinary participants help secure a network, at least indirectly through pools.
Mining vs Staking, Explained
Key takeaways
- Proof of stake secures a network with locked-up capital and penalties rather than electricity and hardware.
- Validators are chosen to add blocks and can be slashed, losing part of their stake, for dishonest behaviour.
- It slashes energy use and lets holders earn a variable yield, but lock-ups and slashing are real risks.
Proof of Stake — preguntas frecuentes
What is slashing?
Slashing is a penalty in proof-of-stake networks where a validator that breaks the rules, such as by trying to confirm conflicting blocks, has part of its staked coin destroyed. It is the deterrent that keeps validators honest.
Do I have to run a validator to stake?
No. Many exchanges and pools let you stake in a few clicks by delegating to their validators. That convenience adds counterparty risk, since you are trusting a third party with the process.
