Crypto staking is the process of locking up crypto holdings in order to obtain rewards or earn interest. Cryptocurrencies are built with blockchain technology, in which crypto transactions are verified, and the resulting data is stored on the blockchain. Staking is another way to describe validating those transactions on a blockchain.
Depending on the types of cryptocurrency you’re working with and its supporting technologies, these validation processes are called “proof-of-stake” or “proof-of-work.” Each of these processes help crypto networks achieve consensus, or confirmation that all of the transaction data adds up to what it should.
But achieving that consensus requires participants. That’s what staking is—investors who actively hold onto, or lock up their crypto holdings in their crypto wallet are participating in these networks’ consensus-taking processes. Stakers are, in essence, approving and verifying transactions on the blockchain.
For doing so, the networks reward those investors. The specific rewards will depend on the network.
It may be helpful to think of crypto staking as similar to depositing cash in a savings account. The depositor earns interest on their money while it’s in the bank, as a reward from the bank, who uses the money for other purposes (lending, etc.). Staking coins is, then, similar to earning interest.
