This is the real bank note or you can use it cash in the old China society. Various of handwriting to indicate the value and multiple stamps from the officials to grant authority to this note.
When I saw this antique in the muzeum it reminds me so much of how our currency have developed. From bank note like this to the fiat currency, then credit cards and here we are in the burst of cryptocurrency.
It is also interesting to see how we moved our trust in the money system. First the people deposit gold or silver into the unincorperated bank and they issue a bank note to act as a bond. And that is a product of trust between the private banks and investor with the value backed by gold inside the vault.
Now we are in the trustless system of cryptocurrency where there is no bank in between the users hence, we don't have to trust anyone. Absolutely an amazing feeling looking at the old bank note that serve no more purpose than just a antique in a muzeum while realizing I have some Bitcoin in my phone which I can spend everywhere.
In the next 100 years, will the blockchain technology and cryptocurrency like Bitcoin survive? Not sure, but I'm certain that they wouldn't be able to stick a Bitcoin on the muzeum wall in 2200.
这是古代的银票，是我在参观青州博物馆时看到的。在上面可以看到手写的各种数字和几个盖章表明着这张银票的权威性和价值。当然现在它们不再是银票，随着时代转变已经变成了博物馆上的文物。
古时候人们都是用金银交易，然后钱庄就出现了。人们只需要把金银存放进去代表了权威的钱庄，钱庄发出张债劵，这就算是中国古社会最早最初的现金雏形。从银票开始，人们经历了现金，信用卡，再到现在的虚拟货币。
这过程中可以很有趣的看到货币系统中的信任转换 。银票可以被使用是因为当时人们信任钱庄真的可以保存对应的金银。然后到现代银行也是一样的道理，我们相信存放进去的钱真的是在里面的，需要的时候银行会如数全给回我们，在太平稳定的国家的确如此。
最后就是无需信任的区块链技术上的虚拟货币登场了，我们正在潮流的前端。
看着这张曾经让许多人趋之若鹜的银票，我想起手机里的虚拟货币，心里不禁感概万千，不知一百年后的比特币会是什么下场。但就算它已经成为历史，我想在 2200 年博物馆的墙上也没办法贴上比特币，毕竟不存在啊，呵呵。
