You commit a chunk of the network's coin as collateral, and in return you (or a validator you delegate to) help confirm new transactions. For doing that work honestly, you receive a steady flow of rewards. If you try to cheat or your validator misbehaves, part of your stake can be taken away. This is called slashing. ## Related terms - [Proof of Stake](https://fudfomo.co/glossary/proof-of-stake): A way to secure a blockchain using locked-up coins instead of computing power.
