Proof of Stake
CryptoGlossary term
Definition
A consensus mechanism where validators are chosen to create new blocks and confirm transactions based on the amount of cryptocurrency they have staked as collateral. It is considered a more energy-efficient alternative to Proof of Work because it does not require massive computational power. Ethereum adopted Proof of Stake in 2022, dramatically reducing its energy consumption.
Related terms
- StakingThe process of locking up cryptocurrency in a blockchain network to help validate transactions and secure the network, in exchange for earning rewards. Staking is a core mechanism of Proof of Stake blockchains and serves as an alternative to the energy-intensive mining process. The more tokens you stake, the greater your chances of being selected to validate transactions and earn rewards.
- Proof of WorkA consensus mechanism that requires miners to solve computationally intensive mathematical puzzles to validate transactions and add new blocks to the blockchain. It was the first consensus method used in blockchain technology and remains the mechanism behind Bitcoin. While highly secure, Proof of Work is criticized for its significant energy consumption and environmental impact.
- EthereumA decentralized blockchain platform that enables developers to build and deploy smart contracts and decentralized applications (dApps). Unlike Bitcoin, which primarily serves as a digital currency, Ethereum provides a programmable platform powered by its native cryptocurrency, Ether (ETH). It transitioned from Proof of Work to Proof of Stake in 2022 to improve energy efficiency and scalability.
- BlockchainA distributed digital ledger that records transactions across a network of computers in a way that makes the data nearly impossible to alter retroactively. Each block contains a set of transactions and is cryptographically linked to the previous block, forming a chain. This technology provides transparency, security, and decentralization without requiring a central authority.
