【Abstract】Consensus protocols are a fundamental part of any blockchain; although several protocols have been in operation for several years, they still have drawbacks. For instance, some may be susceptible to a 51% attack, also known as a majority attack, which may suppose a high risk to the trustworthiness of the blockchains. Although this attack is theoretically possible, executing it in practice is often regarded as arduous because of the premise that, with sufficiently active members, it is not 'straightforward' to have much computing power. Since it represents a possible vulnerability, the community has made efforts to solve this and other blockchain problems, which has resulted in the birth of alternative consensus protocols, e.g., the proof of accuracy protocol. This paper presents a detailed proposal of a proof-of-accuracy protocol. It aims to democratize the miners' participation within a blockchain, control the miners' computing power, and mitigate the majority attacks.

【摘要】共识协议是任何区块链的基本组成部分；尽管一些协议已经运行了几年，但它们仍然有缺点。例如，有些协议可能容易受到51%的攻击，也被称为多数人攻击，这可能会对区块链的可信度造成很大风险。虽然这种攻击在理论上是可能的，但在实践中执行它通常被认为是艰巨的，因为前提是，在有足够活跃的成员的情况下，不可能 "直接 "拥有很多计算能力。由于它代表了一个可能的漏洞，社区为解决这个问题和其他区块链问题做出了努力，这导致了其他共识协议的诞生，例如，准确性证明协议。本文提出了一个详细的准确性证明协议的建议。它的目的是使区块链内的矿工参与民主化，控制矿工的计算能力，并减轻多数攻击。
