Proof-of-stake : ウィキペディア英語版 | Proof-of-stake Proof-of-stake is a method by which a cryptocurrency blockchain network aims to achieve distributed consensus. While the proof-of-work method asks users to repeatedly run hashing algorithms to validate electronic transactions,〔(Proof-of-Work vs Proof-of-Stake ), 31-8-2014〕 proof-of-stake asks users to prove ownership of a certain amount of currency (their "stake" in the currency). Peercoin〔 was the first cryptocurrency to launch using Proof-of-Stake. Other prominent implementations are found in BitShares, Nxt, BlackCoin, NuShares/NuBits and Qora. ==Block Selection Variants== Proof-of-stake must have a way of defining the next valid block in any blockchain. Selection by account balance would result in (undesirable) centralization, as the single richest member would have a permanent advantage. Instead, several different methods of selection have been devised.
