论文摘要
分布式共识机制是快速发展的区块链网络的骨干。区块链平台根据当前共识的工作证明机制消耗大量电力。在这里，我们指出了一种名为“股份证明”的高级共识机制，可以消除当前基于POW的区块链的广泛能源消耗。我们全面阐明了POW和POS基于POS的比特币和以太坊区块链平台的当前和预计的能源消耗和碳足迹。
The distributed consensus mechanism is the backbone of the rapidly developing blockchain network. Blockchain platforms consume vast amounts of electricity based on the current consensus mechanism of Proof of Work. Here, we point out an advanced consensus mechanism named Proof of Stake that can eliminate the extensive energy consumption of the current PoW-based blockchain. We comprehensively elucidate the current and projected energy consumption and carbon footprint of the PoW and PoS based Bitcoin and Ethereum blockchain platforms.
