谈谈Blockstream的Bitcoin人造卫星网络
官网
https://blockstream.com/2017/08/15/announcing-blockstream-satellite.html
几天前，Blockstream宣布了他们要用人造卫星来广播bitcoin区块链数据，Blockstream卫星网络是由三颗地球同步卫星组成，现在已经可以在地球三分之二的土地上使用，这项服务将可以让大部分没有互连网的人也可以免费下载bitcoin区块链数据，包括非洲、欧洲、南美洲和北美洲
现在问题来了，如果你在沙漠，没有互连网，有什么用呢？
比如你是个卖羊的，你在沙漠没有银行户口，只有bitcoin钱包，现在有人转了１个bitcoin给你，你可以用个＄５０的satellite dish来接收人造卫星的bitcoin区块链数据，同步你的钱包，就能查到那个人是否已经把bitcoin给了你，你就可以把羊给他
又或者你住在非洲一些互连网只有１０MB一天的地方，由于用互连网来下载bitcoin区块链数据需要几百个MB，这时候你就能用＄５０的satellite dish来接收人造卫星的bitcoin区块链数据，如果需要交易时才连接互连网，交易只需要几个KB
可惜的是这项project有些blockstream投资者不买帐，因为根本赚不到钱，已经在twitter上谩骂了
因为我是住在城市目前没用到，不过我想这一个项目应该对数字货币是好事吧
科技改变未来
以后卖羊就很方便多了 呵呵
科技改变世界
