Staking is an essential feature of proof of stake (PoS) protocols. Large PoS protocols including Polygon, Solana, and Polkadot allow users to stake their native tokens and earn rewards. 

Blockchain node operators must pledge their tokens, also known as staking, to a network in order to be selected as a block validator. As a reward for correctly adding valid blocks to the blockchain, node operators receive newly minted tokens as rewards, known as staking rewards. 

Node operators who perform invalid functions (eg. adding a corrupted block to the blockchain) could lose a portion of their pledged tokens, a function known as slashing. Our staking validators are highly effective, and we guarantee to reimburse any losses (slashes) due to our validation process.

There are various iterations of proof of stake protocols and a host of features that accompany them. For a deep dive into PoS, we invite you to explore Cryptopedia.
