Proof-of-Stake

Definition ∞ Proof-of-Stake is a consensus mechanism used by some blockchain networks to validate transactions and create new blocks. In this system, validators are chosen to create new blocks based on the number of coins they hold and are willing to “stake” as collateral. This method is generally considered more energy-efficient than Proof-of-Work.
Context ∞ Proof-of-Stake is a frequent topic in discussions about blockchain scalability and energy consumption, particularly following major network upgrades. Current debates often center on the security implications of different staking models and the potential for wealth concentration among large stakers. The transition of prominent blockchains to Proof-of-Stake protocols is a significant development in the industry.
