**争议** 比特币挖矿算法没有考虑一种与80字节的块头相关的攻击方法,包括多种初始64字节块块, followed by相同16字节块块,多个候选根值结束相同4字节,以及涉及平方根数的计算。这违反了安全假设(1)外部随机数输入,进入专门的随机数生成器区域时,不应改变评估难度,(2)每个挖矿函数执行都应该独立。注意:许多人认为这种方法是有益的矿池优化,而不是漏洞。

漏洞描述信息
The Bitcoin Proof-of-Work algorithm does not consider a certain attack methodology related to 80-byte block headers with a variety of initial 64-byte chunks followed by the same 16-byte chunk, multiple candidate root values ending with the same 4 bytes, and calculations involving sqrt numbers. This violates the security assumptions of (1) the choice of input, outside of the dedicated nonce area, fed into the Proof-of-Work function should not change its difficulty to evaluate and (2) every Proof-of-Work function execution should be independent. NOTE: a number of persons feel that this methodology is a benign mining optimization, not a vulnerability
