Crypto staking is the process of holding cryptocurrency in a wallet and participating in the operation of a blockchain network. By participating in staking, you can help to validate new transactions and create new blocks, and in return you may receive rewards in the form of new cryptocurrency. Staking is similar to mining, which involves using computer resources to help validate new transactions and create new blocks, but it is generally less resource-intensive and requires less technical knowledge. Some popular cryptocurrencies that support staking include Cosmos, Tezos, and EOS.
