Staked tokens play an essential role in the DeFi space. They are made possible by the proof-of-stake consensus mechanism, which is used by blockchains like Celo. Staking encourages users to lock their tokens, earn rewards, and participate in governance. When you stake a token, you lock it to support the process of confirming transactions on that blockchain. Investing in crypto without trading has become increasingly popular thanks to staking, and it's a good option for long-term investors who don't care about short-term fluctuations.
