附录２ 比特币改进协议
比特币改进协议（Bitcoin improvement proposals 简称BIP）是为比特币社区提供规范，完善比特币及其运行进程和外部环境特性的设计指导文件。 依据 BIP0001协议即比特币改进协议的目的与指南，比特币改进协议有以下三种类型：
标准协议（Standard BIP）
描述任何影响大多或全部比特币应用的变化，比如网络协议、交易有效性规则的变化，或者任何影响使用比特币交互操作性的变化或补充。
信息补充协议（Informational BIP）
描述比特币的设计事项而不是为其提供新特性，或者为比特币社区提供一般性的指南或信息。信息补充型协议 不一定需要比特币社区达成共识或推荐，因此用户和开发人员可以选择忽略或者接受信息补充型协议的建议。
开发指导协议（Process BIP）
描述比特币进程，或者提议更改进程或事项。Process BIP与Standard BIP 相似，但是也可以应用于除比特币协议以外的领域。在普遍达成共识的情况下，它可以向比特币以外的代码库提出改进建议。与Informational BIP不同，Process BIP 是强制性的，用户必须遵守。例如针对决策进程的过程、指南、改变，在比特币开发过程中使用的工具、环境的改变。任何meta-BIP也应被认为是Process BIP。
比特币改进协议在 GitHub 中更新版本。
表B-1为比特币改进协议一览表（更新至2014年底） 。需要有关目前 BIP 内容的最新信息，请参考官方版本。
