fog VS TextSecure

I had an idea that you could shard the blockchain into multiple parallel networks representing a fraction of the total supply each. This could spread tx volume among each sub-network. Combined with something like Fog for txo recovery could greatly increase the upper bound of scaling on the base layer.

This explains the issues fairly well. tl;dr most blockchains require a large CPU and/or network expensive sync which is prohibitive on mobile. As a fix/hack many web and mobile apps have a SPOF gateway which the client must trust absolutely.

“Monero isn't fast enough and doesn't support transaction recovery (it also has probabilistic linkage which MobileCoin doesn't due to our use of secure enclaves). We spent almost 18 months building MobileCoin Fog to solve the second problem (https://github.com/mobilecoinfoundation/fog). It's a non-trivial stack of code to allow users to recover strings from servers they don't control without the operators of those servers being able to learn what strings are being recovered. Don't get me wrong, we stand on the shoulders of giants, but there's a lot of new tech here.”

I personally love Dash. One thing that was a requirement for me was that privacy in the system can't be optional if you want to give system-wide guarantees about the privacy of the system. That is to say, non-privacy-protecting transactions weaken the privacy of correlated privacy-protecting transactions. Second, I don't personally think CoinJoin goes far enough, specifically there's still a transaction graph to analyze. MobileCoin does not have a transaction graph which is a distinguishing factor from other cryptocurrencies. Finally, other privacy coins have implemented encrypted ledgers (see CryptoNote), which is something MobileCoin has; to the best of my recollection CoinJoin does actually have an encrypted ledger which is a big distinguishing factor. In order for users to recover transactions from an encrypted ledger, you need an encrypted recovery service which, again to the best of my knowledge, no one had ever invented. This is where Fog comes in, which allows fast mobile recovery of user transactions even in an encrypted ledger (https://github.com/mobilecoinfoundation/fog).

Hi,

Before you label MobileCoin a scam, I would encourage you to take a look at the Github. I think you'll see that we've made a lot of very carefully considered choices on how to deliver a great payments experience without many of the compromises other cryptocurrencies have chosen. Of note, the speed of transactions, much greener energy design, privacy-protections, and mobile-first UX are differentiators. Many cryptocurrencies have some of these features, but I don't know of any other that has all of them.

Believe me, I have a lot of feelings about how absurd cryptocurrency has become in the last decade. At its core, I still believe that there is something beautiful in decentralized ledgers and I think that this is the way that the world will settle debts over the next hundred years. Signal chose MobileCoin because nothing else met their performance and privacy standards. In order to meet those goals we wrote a lot of new technology that is fundamentally different from how other cryptocurrencies are architected today (check out our oblivious RAM implementation, for example: https://github.com/mobilecoinfoundation/fog).

I love Signal and I started MobileCoin to help fund their work. For me, a world with Signal in it is a better place.

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...)

Here is one: https://github.com/signalapp/Signal-Android/tree/main/reprod...

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