Proof of Stake (PoS) is a consensus mechanism used by blockchain networks to validate transactions and add new blocks, based on the amount of cryptocurrency participants hold and are willing to “stake.” Instead of using computational power, PoS relies on economic incentives to secure the network.

Proof of Stake secures a blockchain by selecting validators based on the amount of assets they stake.
In a PoS system, participants called validators lock up a portion of their cryptocurrency as collateral to gain the right to validate transactions. The network selects validators to create new blocks, often based on the size of their stake and sometimes additional factors like randomness or staking duration. If a validator acts dishonestly, they can lose part of their staked assets, which discourages malicious behavior. Compared to Proof of Work, PoS is generally more energy-efficient and scalable, but it may raise concerns about centralization if large holders gain more influence over the network.
Short example:
Suppose you stake 10 Ethereum in a PoS network.
The network may select you as a validator to confirm transactions and add a new block.
If you validate correctly, you earn rewards, but if you act dishonestly, you risk losing part of your stake.
