比特币在现实支付中的应用是大势所趋,但我这儿点疑问,望大神解惑。
首先就是支付确认时间问题,比如现在吃饭买单,现金付完直接走人,而用比特币呢,是不是还得在支付后坐那儿等上几分钟,等至少得有一个确认什么的吧,那样才算支付成功。这样不就很不方便么?
不等确认又怕出现什么双花的问题。
再有,比特币的应用越来越广泛,整个Blockchain的大小也会极速增加,只增不减,会不会到了一定时间大得让人接受不了,比如50年后,整个Blockchain的大小会是多少呢?

小额应该问题不大,双花应该是在不同地点,同一时间用同一钱包花btc,这难度有点大。大额等确认。
Blockchain的大小极速增加,10年后说不定硬盘都几千T了,怕什么。

现实生活中用手机支付比特币非常方便。 将来绝大多数商家会接收零确认。 几秒钟就完成支付。  而且手机比特币钱包只用几M字节就行了, 占不了多少内存空间。  想信将来会有更多、更好用的比特币手机应用钱包。
