Abstract

Ethereum はThe Merge アップデート以降、Proof of Stake に移行したことで消費電力がより小さく、また、より安全になったと喧伝されている。しかし、仮にそうだとして、その状態は持続できるのだろうか。この論文では、Ethereum のネイティブ通貨であるEther (ETH)の価格が他のスマートコントラクト基盤との競争の影響を受けうることに注目し、Proof of Stake の設計がもたらすとされる安全性と持続可能性について疑問を投げかける。, Since the Merge update upon which Ethereum transitioned to Proof of Stake, it has been touted that it resulted in lower power consumption and increased security. However, even if that is the case, can this state be sustained? In this paper, we focus on the potential impact of competition with other smart contract platforms on the price of Ethereum’s native currency, Ether (ETH), thereby raising questions about the safety and sustainability purportedly brought about by the design of Proof of Stake.
