For instance, some cryptocurrencies use the concept of "coin age", the product of the number of tokens with the amount of time that a single user has held them, rather than merely the number of tokens, to define a validator's stake.

Proof-of-stake is a method of securing a cryptocurrency network and achieving distributed consensus through requesting users to show ownership of a certain amount of currency. It is different from proof-of-work systems that run difficult hashing algorithms to validate electronic transactions. The scheme is largely dependent on the coin, and ...
Ouroboros is a family of proof-of-stake consensus protocols used in the Cardano and Polkadot blockchains. It can run both permissionless and permissioned blockchains. [1] Ouroboros was published as "the first provable secure PoS consensus protocol".
In blockchains that use a PoS system — as opposed to proof-of-work (PoW) — nodes in the network engage in validating blocks, rather than mining them. A deterministic algorithm selects block ...
