Definition
Pure Proof of Stake is a consensus concept in which a blockchain selects participants to propose and validate blocks using a random process that is weighted by the amount of coins they hold. Unlike systems that rely on specialized hardware or fixed validator sets, it aims to involve the entire set of eligible token holders in securing the network. The “pure” aspect emphasizes broad, stake-based participation rather than limiting validation to a small, pre-approved group.
In this model, the probability that an account is chosen to help create or confirm the next block is proportional to its stake, but the actual selection is randomized to prevent predictability. This structure is designed to align the security of the blockchain with the economic interests of its participants, since those with more at stake have a stronger incentive to maintain honest behavior. Pure Proof of Stake is typically used to support efficient, low-energy block production while maintaining decentralization among coin holders.
In Simple Terms
Pure Proof of Stake is a way for a blockchain to decide who gets to add the next block by randomly picking from all coin holders, giving better odds to those who hold more coins. It does not depend on powerful mining machines, but instead on how many coins an account has locked or owned. This approach treats coin ownership as the main signal of who helps run and secure the network.
Because selection is random but weighted by stake, no single participant can easily control the process without owning a very large share of the total coins. The concept focuses on using economic ownership rather than computing power to support the chain’s security and block creation. It is meant to keep the system efficient while still allowing many different holders to participate over time.
