Signal adds a payments feature with a privacy-focused cryptocurrency

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 a while to come back.

The best set of docs for how the whole thing fits together is our book "The Mechanics of MobileCoin"[0].

We'll be around here and on our forums [1] to answer questions. Please also check out our foundation website[2]. The github[3] is also a lot of fun, especially the section on Fog[4].

Thanks for answering questions, it's nice to see that MobileCoin shares so many similarities with Monero with changes that seems to make decent tradeoffs for usability. I have a few questions:

What is the identity and distribution behind the current mobilecoin nodes? What are the requirements for running a node? Since there is no node rewards how will nodes funded in the long term (10+ years)?

Does mobilecoin employ something similar to Dandelion++? What prevents nodes or those running fog from performing timing based attacks? Is mobilecoin suseptable to any other attacks (e.g. Poisoned output, subaddress association)?

How will the mobilecoin foundation and continued development be funded in the long term (10+ years)?

If SGX is found to be vulnerable/no longer fit for purpose is there a mitigation plan?
