楼主，1 楼和 11 楼说的孔夫子，多爪鱼，都是二手图书交易市场啊。可以搜一下 v 站的老帖子，很多关于图书交易的讨论。

共识其实是统一，而损耗率这种，需要的应该是竞争，而不是统一。统一了还有啥活力？这跟交易有效性的统一共识完全不是一个作用。

这个很难想象。现实世界中，央行通过存款准备金率，商业银行通过不同的利率去适应调整，还有个竞争的过程。
比特币系统也能做到吗？比较怀疑。

还是需要请懂这块的来解说解说啊。 @BingoXuan

再写清晰一点吧：
现实经济世界中，央行是作为一个自适应的调节者存在的。根据现实经济的情况调节经济。

那么比特币系统也肯定需要调节以适应现实的经济，靠什么调节呢？即使是这样一个简单的贬值速度，如果不能根据现实调节，也会造成很严重后果。

想法出发点很好。但可以分析一下：

如果贬值是为了祛除比特币的通缩属性，那也要看这个贬值的幅度。比如像现在比特币作为避险，黑市，投机的用途，是因为人们预期它会上涨。而这个预期是动态变化的，那么要想抵消这种预期，比特币的贬值应该也是动态自适应的。问题是，比特币的贬值是比特币系统里的一个规则，怎么把真实世界里的调控参数输入到这个分布式系统里呢？

假设比特币的价值在于真正的交换价值，也就是类似于法定货币，那么怎样把央行的调控模式转换为去中心化系统的自适应呢？

你说的这个贬值速度，固定写在比特币系统里肯定是不行的，但有没有可能让它自适应，同时能反应真实经济世界的变化？就像央行一样。

分别用公司的网络(北京移动)，还有自己的 4G(北京移动，北京联通)热点测了一下。
测试方法：tcping -t github.com 443，浏览器并没有打开 github.com ，只是单纯的 tcping...

规律如下：

公司网络(北京移动) ，4G 热点(北京移动)：
跟楼主一样，每次超时，时间是非常准确的 3 分钟。比北京的“大姨妈式进京证”还要准确。
超时后，会出现短暂的 ping 通，时间不等，最短只 ping 通一次，最长几十秒。


4G 热点(北京联通)：
非常有规律的超时，且每次超时只维持 1，2 次 No response，其余时间都是 ping 通。每段 ping 通的时长，大概是 10s 或者 5s 。没有过多测试。这部分的具体数据如下：

```
C:\Users\**>tcping -t github.com 443

** Pinging continuously. Press control-c to stop **

@zhongrs232 No 。今天恰好套了一个被子，有感而发。

@ETiV 厉害啊，下次试试。
