Super sad that they didn't choose Monero.

That was my first thought as well. Why didn't they pick Monero? I don't see how any other coin could be better.

No near-instant confirmation, maybe. At first glance not a big problem for users, but can run you into a lot of problems

Multiple reasons why MOB over monero but I will state only the most practical one, using the stellar consensus a tx takes 3-5sec. With monero that's more like 1-2mins if Im not mistaken which is a big no-no for the usecase of instant mobile private payments. Fees are also super low w/ mob (0.01)

TLDR: UX

Signal is still centrally controlled and compiled by a single entity and distributed only in an unsigned insecure form or in a signed/verified manner only if you give up your privacy to install with Google Play or the Apple store. Those that only run open source software like myself have no secure way to run Signal short of compiling every release by hand which is impractical. Moxie has stated he will not support any…

Even if an SGX attack does take place, tx's aren't recognized as the system is secured with Cryptonote's ring signatures (1st reply in FAQ https://github.com/mobilecoinfoundation/mobilecoin ) here too about 11mins in - https://www.youtube.com/watch?v=e9afDQ_M5CU

The problem is: Signal already relies on SGX for lots of other features (Signal PINs & Secure Value Recovery, contact discovery etc. etc.) and these depend on SGX working as advertized.

There are 250 million units of mobilecoin, and majority of them are owned by the founders. Only 37.5 million have been distributed. With current price ($65), they're worth $14B already. This makes the project a scam and impossible for it to work as a reliable money that holds value. Bitcoin had no pre-mine and has been fairly distributed from the start.

Even UK-only release in Signal means more people with cryptocurrency wallets than all other cryptocurrencies combined.

It's roughly similar to Brave's userbase, though Brave is opt-in. Figures from 2020 put both in the low tens of millions.

Earlier quoted context omitted.

Were there things that you didn't like about Stellar? Or did you modify it to fit a different use case? (thanks for answering questions!)

We wanted more guarantees around safety. Stellar isn't written in Rust and Rust has some very nice safety properties that we felt were valuable enough for a full-on rewrite. We also wanted to be able to hand-tune the performance of the system, and the only way we could really get to that level of control was to do it ourselves. Finally, we wanted to perform consensus on encrypted values so that the nodes wouldn't be…

Is it true that it only works on Intel now?

For those wondering about volatility... > MobileCoin also remains even more volatile than older cryptocurrencies, with constant price swings that will significantly change the balances in a user's Signal wallet over the course of days or even hours—hardly the sort of issue that Venmo users have to deal with. (Since March 27, MobileCoin's value has shot up nearly 600 percent, possibly due to rumors of the impending Si…

The project is brand-new, what do you expect? In any case, the end-game is to use MOB for the transaction and instantly convert to fiat, so volatility would not be of concern to the end-user

Hi! I'm the CEO of MobileCoin. If anyone has any questions please feel free to ask here. We've been working on this project for four years and it has been a labor of love. There's a lot of new technology here. We exist in a highly regulated space so it's possible some questions will require reaching out to lawyers to make sure we answer them in a way that's compliant so please don't feel offended if a response takes…

Can late MobileCoin adopters buy the same amount of coin for the same price as early adopters or is it a multi-level marketing pyramid scheme like the rest of the crypto“currency” greed and spam inducing cesspool? https://www.cynicusrex.com/file/cryptocultscience.html

MobileCoin is already liquid on multiple exchanges so the coins would just be purchased at whatever the market price is. It also doesn't make sense for late adopters to get the same price because there's a lot more risk associated with being an early adopter than a late adopter. This works both ways — if something bad happens to MobileCoin that tanks the price late adopters would be able to buy at a cheaper price because the new information gets priced in.

Why does a decentralized communication system need a defi based payment system that has the requirement of a CEO to run it?

Nope: https://signal.org/android/apk/

You may be missing the subtle point - the APK provided is the same one from Google Play, which includes the Google SDK encumbered libraries (links? hooks? features?). If you run a libre device without the Google Play store (non-Google android build) then the software cannot function. The code for the client is open source, but the act of compiling it against the required Play store libraries encumbers the final binary. F-Droid requires that all code compile without the Google SDKs in order to be hosted (IIRC).

1. MobileCoin premines 250m coins

2. Moxie gets paid for being on their advisory board

3. Moxie directs his non-profit to integrate MobileCoin in secret

4. MobileCoin offers 1/5 of their premine for sale.

5. Signal announcement spikes price to $60

How accurate is this?
