Stephen Diehl hates cryptocurrency, and that's fine, but does he have an alternate payments proposal?

If not, it's poor form to say that people shouldn't be able use something that works for them.

That’s true for a lot of crypto but not for something like monero which has an anonymous blockchain.

It's anonymous with some caveats. The transaction graph is still there, it's just that there are decoy inputs/outputs which provides plausible deniability. However, over repeated transactions the plausible deniability weakens. ie. having an output to a darknet market in one of your transaction is easily explainable by bad luck, but it's present in several transactions it becomes suspicious enough that the police can…

This isn't the case, monero employs stealth addresses so there is no way to tell who the recipient is just just by observing the blockchain.

Can you talk about scaling issues. What are your projections for the size of the MobileCoin blockchain, assuming it is successful and people want to do >1000 transactions/second.

We've tested MobileCoin at ~100 transactions per second right now using low core count boxes. We suspect we can scale to 10,000/second on the existing tech stack by throwing bigger boxes at it AND doing some performance tuning. SCP has been shown to hit very large tx/s numbers so it's just a matter of tweaking it until we get those numbers out. 100 tx/s is more than adequate for quite some time for our use case.

I was thinking more along the lines of storage requirements. How much space would be consumed on a full node by a network running at constant 1000 tx/sec?

Shit. Just as I convinced all my family and friends to move out from whatsapp and I uninstalled the stupid green app. What do we get to do now?

If you are looking for e2e encryption, it all depends on which features you need (like voice messages) and how good usability and UX needs to be for your family and friends to adopt the new tool. Some candidates are * GNU Jami: https://jami.net/ * Matrix with Element: https://element.io/

Jami has it's own tradeoff as you'll be revealing your IP in a DHT.

I remember that Skype, before it was bought and ruined by Microsoft, had P2P chat history sync that worked the following way: once two of your devices were online at the same time, they synchronized chat history among the two running instances flawlessly. It was super reliable and predictable. I am sure that Signal could implement the same peer-to-peer sync scheme with full end-to-end encryption without any secrecy c…

This is actually working very bad in most practical situations. The way to go is Telegrams way, where you store all data on the server and happily sync ut easily between devices. Just do it on your own server using xmpp. E2ee helps mostly against server owner, and you eliminate this risk by being your own server owner.

> Just do it on your own server

What if I don't have and don't want my own server?

Scooping the cream off every monetary transaction between some friends is a more appealing proposition than hoping some people will pay for your software.

Apple Pay, Google Pay, Visa, Signal - there is a lot of companies basing their business model on Office Space. Hackers had the same theme, right? And Operation Swordfish, which was trash.

Hackers is just getting better with age.

I definitely agree with the article that it felt a bit like a betrayal. I've pushed some friends and family to use it over Telegram despite significant usability issue, and now I see that instead of implementing some IMO basic features like proper message sync and easy backup when you get a new phone, they prefer to implement a... micropayment system? Based on some niche altcoin which doesn't even exist on mainstream…

Proper message sync is hardly possible with end-to-end encryption everyone so excited about (without fully understanding the implications of true secrecy). If you have e2ee and then sync messages via google drive (looking at you, Viber), you are kinda missing the point.

> Proper message sync is hardly possible with end-to-end encryption

iMessage (and soon WhatsApp) would beg to differ.

It is much more difficult, yes, but definitely not impossible.

XMPP is extremely light, you can use a moderately powered personal computer to handle traffic from several users. I don't have the numbers with me but last I'd heard, the number was in the hundreds.

ejabberd can host ~2k active connections on $2/month server.

Where can I get this $2/month server?

The nice thing about client-side/end-to-end security is that the service provider matters less.

Also, $2/month is $2 more than many people would be willing to pay for private messaging, and I can't message people on a network they're not on, no matter how much I pay.

All the dumping on signal is sad. Here we have an nonprofit app that has succesfully broken into a major consumer market, and because of their ambitions to break up another cartel, and this is bad ? Lets take a stab at understanding the authors complaints. Author states users are smart and "we make the majority of users". Going beyond the entitlement of that statement, author can feel betrayed, but for signal to succ…

>Its time to cheer, not to dump.

Very poor choice of words.
