多数并非必需:一种针对自私挖矿的反制策略

Majority is not Needed: A Counterstrategy to Selfish Mining

Jonathan Gal, Maytal B Szabo, Ori Rottenstreich

AI总结:

本文针对自私挖矿提出一种无需多数算力的反制策略:大矿池可利用自私矿池攫取全部利润并实施双花,从而威慑各类偏离策略。

摘要:

在过去几年中,若干论文研究了自私挖矿攻击,其中大多数假定每个不属于自私挖矿矿池的矿工都会继续诚实挖矿。然而在现实中,保持诚实并不总是受到激励,尤其是在另一个矿池正在采用自私挖矿或其他偏离策略时。在本工作中,我们探讨这样一种情形:一个足够大的矿池利用另一个自私矿池,获取100%的利润并实施双花攻击。我们表明,这种反制策略能够有效对抗任何偏离策略,而且即便只是存在这种可能性,也会阻止其他矿池实施偏离策略。

英文摘要:

In the last few years several papers investigated selfish mine attacks, most of which assumed that every miner that is not part of the selfish mine pool will continue to mine honestly. However, in reality, remaining honest is not always incentivized, particularly when another pool is employing selfish mining or other deviant strategies. In this work we explore the scenario in which a large enough pool capitalises on another selfish pool to gain 100\% of the profit and commit double spending attacks. We show that this counterstrategy can effectively counter any deviant strategy, and that even the possibility of it discourages other pools from implementing deviant strategies.
