What is the Definition of Proof Stake?

Proof of Stake represents a consensus mechanism within blockchain networks where participants are selected to validate transactions and create new blocks based on the amount of cryptocurrency they hold and commit as collateral. This "stake" serves as a financial security deposit, incentivizing honest behavior among validators. Should a validator act maliciously or fail to perform their duties, a portion of their staked assets may be penalized. This method aims to offer a more energy-efficient alternative to proof-of-work.

What is the Context of Proof Stake?

The transition of major blockchain networks to proof of stake has significantly impacted discussions around network scalability, decentralization, and environmental sustainability. News reports frequently compare the security and economic models of proof-of-stake systems against older proof-of-work protocols. Ongoing developments focus on enhancing validator decentralization and addressing potential centralization risks associated with large staking pools, alongside regulatory considerations for staked assets.
