Crypto Staking is keeping a cryptocurrency in the wallet for a fixed period of time and earning interest on it. This is pretty much analogous to a person earning interest by depositing money in a bank account or time deposit savings account.

In staking, the user supports the transactions of the blockchain network by holding cryptocurrency funds in a wallet and earns rewards for participation. This mechanism, called "PoS - Proof of Stake", gives currency holders some power to make decisions regarding the network.

Unlike Proof of Work (PoW), which relies on mining to verify and generate new blocks, PoS generates new blocks without the need for mining hardware. Since the validator is selected based on the number of funds users deposit into their wallets, there is no competition among the transactors (users) to add new blocks. The more money a user deposits as a bet, the higher the chance of being selected as a validator and the higher the revenue.

Users do not need to buy expensive and powerful computers to verify and start earning rewards. Also in PoS, it is faster, more energy efficient and environmentally friendly than the PoW protocol.
