Proof of Stake (PoS)
Definition
Proof of Stake is a consensus mechanism where validators are chosen to create new blocks based on the amount of cryptocurrency they have 'staked' (locked up) as collateral. It is far more energy-efficient than Proof of Work. Validators risk losing their staked tokens ('slashing') if they act maliciously. Ethereum, Cardano, and Solana use variants of PoS. Staking rewards incentivize participation and typically yield 3-15% annually.
Why Does This Matter?
Understanding Proof of Stake (PoS) is essential for anyone investing in cryptocurrencies or working with blockchain technology. This concept directly influences how projects are valued, how markets behave, and what risks and opportunities exist for investors.
