了解区块链重组

[英]Understanding Blockchain Reorg

原文 2022-06-25 04:37:49 9 1 blockchain/ ethereum/ bitcoin/ proof-of-work

I cannot find any good explanation about these 2 statements about reorg:我找不到关于这两个关于重组的陈述的任何好的解释：

1.Reorgs can increase the number of nodes within a blockchain over time, causing a poorer user experience. 1.Reorgs 会随着时间的推移增加区块链中的节点数量，从而导致更差的用户体验。
Why reorg increases the number of nodes?为什么 reorg 会增加节点的数量？

2.When reorging becomes more common, attackers only need to beat a portion of honest miners (due to the “longest chain rule”) rather than all of them. 2.当重组变得更加普遍时，攻击者只需要击败一部分诚实的矿工（由于“最长链规则”）而不是全部。
Why is this so?为什么会这样？

1.Reorgs can increase the number of nodes within a blockchain over time, causing a poorer user experience. 1.Reorgs 会随着时间的推移增加区块链中的节点数量，从而导致更差的用户体验。

It doesn't.它没有。 The statement doesn't make sense.声明没有意义。 Likely the source you are citing is incorrect.您引用的来源可能不正确。

2.When reorging becomes more common, attackers only need to beat a portion of honest miners (due to the “longest chain rule”) rather than all of them. 2.当重组变得更加普遍时，攻击者只需要击败一部分诚实的矿工（由于“最长链规则”）而不是全部。

Ethereum doesn't have the longest chain rule, but the heaviest chain rule , so this statement needs to be rewritten for Ethereum.以太坊没有最长的链式规则，而是最重的链式规则，所以这个语句需要为以太坊重写。 Thus, this rule is probably about Bitcoin and other proof-of-work chains that rely on longest chain rule.因此，这条规则可能是关于比特币和其他依赖最长链规则的工作量证明链。 However, without context, it is not good to have security related discussion.但是，如果没有上下文，就不好进行安全相关的讨论。
