比特币改进提议(BIP)科普,你知道有哪些BIP落地了吗?

王司徒 发布在 技术指南 5 5860

最近有一项新的比特币改进提议(BIP)因其具有非常大的争议性而被社区广泛关注,它就是BIP 148 (隔离见证部署强制激活),其涉及到一种新的软分叉方式——UASF(用户激活软分叉)。根据这一提案的描述显示,如果现有的隔离见证部署在2017年8月1日之前无法激活,那么该BIP将在2017年8月1日至2017年11月15日午夜之间的一个时间点激活。但如果现有的隔离见证部署激活,那这个BIP将停止被激活。

对此,社区内就有人将其解读为:CORE已经放弃95%算力投票共识,将在8月1号无条件强制激活隔离验证

这里就有一个误区,会有人把草案阶段的提案理解成CORE的共识,也就是Final(落地)阶段。

为了避免让大家产生不必要的误会,这里王司徒有必要科普一下BIP从提出到落地需要经历的步骤,以及当前究竟有哪些BIP。

Bitcoin Improvement Proposal

 

1.BIP提交及审核过程是怎样的?

 

想要提交BIP,首先应该把自己的想法或文件发布到邮件列表。在经过讨论之后,发起者需要通过电子邮件联系Luke Dashjr <luke_bipeditor@dashjr.org>。经过Luke Dashjr的编辑和通过之后,BIP就会在 https://github.com/bitcoin/bips 发布了。

根据规则,任何人都是可以提交BIP的,注意,在https://github.com/bitcoin/bips 页面上发布一个BIP,并不代表它已被正式接受,当其状态变为激活(Active)时才算正式被接受。而想要让一个BIP正式激活,这需要经过开发者社区的协商同意。

而当前BIP的状态一共可分为9种,它们分别是Proposed (提出)、Draft(草案)、Active(激活)、Final(落地)、Replaced(被替代)、Withdrawn(撤掉)、Deferred(推迟)、BIP number allocated (BIP编号被分配)、Rejected(拒绝)。

巴比特论坛版主玛雅则根据他自己的理解将这个过程分为了7步

第1步:想法,任何一个人都可以通过任何途径渠道,如论坛,推特等等,提出自己改进初步想法,来争取更多人支持认同。
第2步:提案,可以汇总社区讨论的建议,以较规范的格式,详细地描述方案,形成一个BIP提案文件提交。
第3步:正式提案,对较重要或者认可的人较多的BIP提案分配序号。以便方便大家讨论区分这个提案,有序号的提案算是正式提案。
第4步:落实代码,一些开发者会依据BIP正式提案的构思,落实成具体的代码。并且在测试网络上进行严格的测试。以确保代码尽量没有Bug。
第5步:激活设定,代码没有问题后,根据《BIP9升级规范》,设定激活门槛,分配激活标记位,缓冲时间等。
第6步:发布版本,若足够多的人签名同意,那么会吸纳此BIP代码在最新版本中发布包含这个BIP代码的版本,但是处于未激活状态。
第7步:激活,等待达到BIP9设的激活门槛后,方案正式激活生效。实测是否方案成功。若出现问题可能回到上一版本。

而当前极具争议的BIP 148,目前只是处在草案阶段(Draft),并且根据多位开发者的反应,这一草案能够激活的可能性非常低。

有意思的是,在所有的BIP当中,唯一一个处于Rejected(拒绝)状态的BIP,就是Gavin Andresen提出的BIP109。

讲到这里,读者对BIP也应该有所了解了,关于BIP我们应该要理性对待,只有在进入Active(激活)状态时,我们才认为它是被Core接受的。(本文纯科普,不代表个人立场)

    那为何没有一个正式的BIP可以改变比特币2100个上限?能够正式拿到BIP就已经代表CORE想这么干。请问为和EC(涌现共识)无法有正式BIP?EC现在怎么说都超过40%算力支持,为何无法拿到正式BIP?

      很简单,因为BIP首先要经过Luke Dashjr这道关,他不同意就过不了
