Crypto staking is a process where you lock up your cryptocurrency to support a blockchain network’s operation and security. This is done on blockchains that use a Proof-of-Stake (PoS) consensus mechanism. Stakers are rewarded for their contributions, which helps secure the network and validate transactions. This method has become popular for earning passive income from crypto holdings and is seen as more environmentally friendly compared to Proof-of-Work (PoW) mining.
