Grin is supposed to be private. If there were addresses, then everyone in the world would know how you’re getting and spending money. If there are no addresses, then Grin must be passed from one hand to another with a point of live contact.
No privacy means no Grin. There are thousands of non-private coins you can use. As Neo-Geo says, file transfer is the most ‘convenient’ this could get.
1、Grin 官方钱包的Slate 文件发送方式可用。Round Trip 还是需要的，也就是收方需要接收并做签名处理后发还给付款者，这个完全异步，效率较低，且安全性是个问题。
2、用 Keybase 做传输。缺点是 Keybase 用户群比较小。
3、用 Grinbox 或 Grinrelay 方案，好处是提供端到端加密，缺点是大部分交易所和矿池都不支持。
我不觉得 Grin 有必要提供原生的离线首付款功能支持，因此只在 Gotts 项目中开发带地址功能的 Non-Interactive Transaction。
Your response completely ignores addresses used just to build transactions, like tor onion addresses. It also ignores many cryptographic solutions, like stealth addresses.
Dude, use google translate or another translator and put your comments in English. Would be more respectful to people that do not understand your native language
So far I personnally only understand your smileys, such as
True, but all those ‘solutions’ are un-Grin and already exist, as you yourself mention. It’s just a pet peeve of mine, people asking for Grin to change in what is quintessentially Grin. (And if the person doesn’t wish to communicate in the international language, how much nuance do they deserve?)
