The rewards could be huge if payments via messaging apps takes off in the west. It's really too bad WhatsApp sold to Facebook of all places.

We could have a privacy-oriented chat platform with a cryptocurrency "small cash" type of transaction system built on top. Combined with some informal craigslist style mini-stores, which flourished in China via Wechat.

I'm sure FB/WhatsApp could do it via normal payment channels, probably involving Visa/Mastercard. But the privacy story is awful for such a critical piece of software. Assuming they could pull it off. Maybe Kik could take up the privacy flag?

WSJ made a nice video of how Chinese people live "cashless" via WeChat in Shenzen: https://www.youtube.com/watch?v=75AXINUL47g

Don't know enough about crypto, but whats the benefit of a payment system for messenger apps to run on crypto at all? If you're transacting through a centralized messaging platform doesnt that defeat the purpose of a decentralized currency or ledger?

It would open up ways to get money into and out of your chat app with less friction.

Also saves you from the "How do I know you won't run off with the money?" and "What happens if Kik goes out of business?" questions. The value of a blockchain is that your digital tokens exist independently of the sponsoring organization, so the sponsoring organization cannot just alter or shutdown their database to make your funds go poof.

Granted, if Kik went bust tomorrow those tokens would most likely have no value, since their use is tied to Kik's messenger app. But in theory you would still own the tokens and could transfer them to anyone who would accept them.

That's only true in the case where the underlying cyptocurrency is actually accepted outside the platform. In theory, if your app is transacting money, it keeps the equivalent cash in an insured bank account which is exactly how PayPal and similar work. If it's not widely accepted, it's basically the same as in-game tokens/currency. Speaking of in-game tokens, people have used them for the same purpose of cryptocurrency e.g. capital flight and money laundering.

"Maybe Kik could take up the privacy flag?"

I feel like most services that aim to replace another one ... just want that information for their own purposes, not the customer's benefit.

If you think the WhatsApp situation is sad, start thinking about Skype and Paypal.

Theoretically this could be possible now with existing cryotos by making small wallets for micro transactions. The chat app would just need to link your blockchain address to make it easily copy and paste-able

there is no way Whatsapp would be allowed to use a privacy oriented crypto. All payment are under surveillance, except cash.

true, but their primary user base is teens that barely have a credit card.

FBMessenger already has best in class payments built in, without crypto.
