PoW（Proof of Work，工作量证明）是区块链领域最早且最具代表性的共识机制之一，其基本思想是通过竞争完成一个有难度的任务来决定区块记账权。任务的设计原则为：计算答案极其困难（需要大量算力和时间），但一旦得知答案，验证其正确性却非常简单且迅速。网络可根据整体算力动态调整难度，确保出块时间相对稳定。最早由中本聪于2008年在比特币白皮书中提出，并在2009年比特币主网上线时正式采用，以消耗大量算力竞争出块为主要特征。PoW机制以其去中心化程度高、安全性强、不易被攻击等优势，被比特币、莱特币、以太坊经典（ETHW）、门罗币（XMR）、狗狗币（DOGE）等众多主流加密货币广泛采用，是区块链发展史上最基础、最成熟、经过最多实战检验的共识机制。
