此方到彼方——双方对等交易steemCreated with Sketch.

in #cn6 years ago

双方对等交易是应用区块链技术而创生的数字币(如比特币等)技术特质的精髓。

此点对彼点(PtoP),就是将信息由此到彼或由彼处到此处的交互。我这里发送信息到你处,你处发送信息到我这里。

“汇兑”是汇款人委托银行将其款项兑现支付给收款人的结算方式。以前,汇兑分为电汇和信汇两种。在这两种汇兑结算方式中,信汇花费的费用较低,但速度相对较慢;而电汇具有速度快的优点,但汇款人要负担较高的电报电传费用,因而通常只在紧急情况下或者金额较大时才用。另外,为了确保电报的真实性,汇出款项的银行在电报上加注汇兑双方约定的密码;而信汇则不须加密码,签字即可。

传统的汇兑方式是:
汇款:此汇款方<=>银行<=>彼收款方

或者,
汇兑方式是:
汇款:此方<=>银行<=>彼方

比特币技术的诞生,银行是个“多余项”。比特币采用 PtoP 方式,即“彼此汇兑”方式:
汇款:此方<=>彼方

所以,PtoP 含义就是双方对等的彼此汇兑。

PtoP,彼此对等,不是所谓的“皮二皮”(P2P)!
