TextSecure VS Mechanics-of-MobileCoin

Moxie's reasons for disallowing Signal distribution via F-droid always rang a little flat to me ( https://github.com/signalapp/Signal-Android/issues/127 ). Lots of chatter about the supposedly superior security model of Google Play Store, and as a result fewer eyes independently building and testing the Signal code base. Everyone is entitled to their opinions, but independent and reproducible builds seem like a net positive for everyone. Always struggled to understand releasing code as open source without taking advantage of the community's willingness to build and test. Looking at it in a new light after the XZ backdoor, and Jia Tan's interactions with other FOSS folk.

Signal has documentation on how to reproduce their Play Store builds and compare them with what you've installed locally:

There's nothing on Signal blog as of yet, but Signal's git repository was tagged with v7.0.0 yesterday and we can see from the commit history since the previously tagged version (v6.74.4) that there will be a setting to hide one's phone number [1], as well as disabling the previous default behavior of advertising that one is on Signal to all their contacts already using it [2].

Signal works the same but without the user tracking from Meta/Facebook. Many people use it as well but I'm surprised that a majority sticks to WhatsApp.

Telegram and Signal solve this.

Sadly yes: Looks like an open issue 13290 for Signal, sounds like they were/are indeed still interacting through google's push notification service, wat, and per a link at that issue it was a chore for Tutanota to break away once they realised it was a problem some years ago (though at least they thought about it years ago? wtf Signal...)

Rule 1: Posts to r/signal must relate to Signal.

Source: a book-length overview of MobileCoin written by a respected member of the Monero community.

Seems like this isn't getting much circulation yet, not the easiest thing to find despite its importance. The Mechanics of MobileCoin, First Edition published April 6, 2021.

That's not the official whitepaper, this is a very outdated spec - this is the latest up-to-date whitepaper https://github.com/UkoeHB/Mechanics-of-MobileCoin/blob/master/Mechanics-of-MobileCoin-v0-0-39-preview-10-11.pdf

Blockchains can use DAGs. Check out this pdf document which you can find in this github repo. It explains some details of mobile coin.

It is based on monero, from their whitepaper edit of zero to monero it looks to be Monero + Stellar Consensus with SGX so they're trading some privacy and a lot of decentralisation for speed.

This whitepaper is not the whitepaper I wrote back in 2017. We took that down because it was ultimately not the design we implemented. The full system design can be found here: https://github.com/UkoeHB/Mechanics-of-MobileCoin/blob/maste....
