每个用户都是一个网络节点的现状，并非大规模阶段的预期形态。那就像每个 Usenet 用户都跑自己的 NNTP 服务器。这个设计支持让用户就只做用户。跑一个节点的负担越重，节点就会越少。那少数节点会是大型服务器集群。其余的是只做交易、不挖矿的客户端节点。
The current system where every user is a network node is not the intended configuration for large scale. That would be like every Usenet user runs their own NNTP server. The design supports letting users just be users. The more burden it is to run a node, the fewer nodes there will be. Those few nodes will be big server farms. The rest will be client nodes that only do transactions and don't generate.

Besides, 10 minutes is too long to verify that payment is good. It needs to be as fast as swiping a credit card is today.
看那个零食机主题，我在里面概述了支付处理服务商如何在大约 10 秒或更短时间内把支付验证得足够好，实际上相当好（欺诈率远低于信用卡）。如果你不信，或者没看懂，抱歉，我没时间说服你。
See the snack machine thread, I outline how a payment processor could verify payments well enough, actually really well (much lower fraud rate than credit cards), in something like 10 seconds or less. If you don't believe me or don't get it, I don't have time to try to convince you, sorry.
