As I say, this is a foundational issue that every blockchain project should address. Before I asked my initial question, I searched the documentation to see if it had been addressed. Such answers might be a second layer story, or some form of transaction aggregation on the base layer blockchain. I could not find anything that obviously looked like that.

At this point I think it's perfectly fair to start with the assumption that a new Crypto is a scam and it needs to do the legwork to show that it isn't. To claim that a blockchain (the most ludicrously inefficient data-structure ever devised) can scale to a billion users is an outrageous claim. The technical means they found overcome this problem should be front and center in their documentation.

I am going to do an AMA over at r/signal on Tuesday at 10am; please save questions for over there as I have to get back to work. I'll say this: the punchline here, as I'm sure you're aware, is that there are limitations to layer 1 scaling. We haven't discovered those limits at MobileCoin, but they surely exist.

The question becomes: what is tx throughput at N billion users? What are the scaling strategies that will get us there? It is zk-rollups (or zk-zk rollups)? Is it sharding? Is it moving to custom hardware circuits? I suspect it will be some combination of all of the above.

We don't know what the answer is yet and we will devote tremendous resources to figuring it out. I don't want to give the impression that MobileCoin as it is written today will scale to Alipay levels of tx throughput, but I do believe there is a path to get there that requires a ton of work.

Does that answer your question?

It answers it, in the sense that it acknowledges that the question remains to be answered.
