If you can find a way to do ZK-proofs that work in the time constraints that we have (1-3 seconds end to end transaction completion and finality), then we'll switch to them. Right now this is the only way we could get the performance w

Stellar is essentially a liquid democracy system similar to DNS. The core proof at the heart of David Mazieres paper is that in a densely interwoven graph, any set of nodes in a quorum slice reaching consensus is graph consensus. Regardin

Moxie != Signal. Moxie, as an individual, is a paid technical advisor to MobileCoin but the reality is that we could never pay Moxie what his time is worth. I am thankful that he has chosen to help make this project a reality.

Stellar actually does nothing to prevent double-spends as it is the consensus layer and not the ledger. The ledger prevents double spends in mobilecoin by using a proof called a "key image" which is part of CryptoNote ( https:&#x2

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 o

MobileCoin has not yet paid Signal anything for integrating MobileCoin. We intend to donate a great deal of money to Signal over the coming years. We believe in Signal's mission and we think that the world is a better place with Signal

I don't think Signal has any plans to scan your driver's license. What they've built is a non-custodial wallet (IE, they can't help you if you lose your keys, and they have no ability to authorize or deny a payment on yo

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

Cool thought. I haven't figured out how to intelligently have a content-based news feed AND a serialized canonical feed of messages without making an algorithmic news feed. Turns out writing news feed is a pain in the butt.

Man, just coming back to this thread. Thank you for saying this. To add a slight bit more color, I didn’t think of myself as fat and depressed in that moment, more that I had been feeling gorged on the emotions of life and had metaphoricall

Chick asked me to sit in a chair a couple feet away from his piano. He stared at me with the a look that seemed to say "whatever you've got, I'll work with it." If I had to imagine how I looked back at him in that moment

Chick Corea was a god. I learned Spain on the bass in the hopes that one day I could play my meager rendition for him. In a concert at SFJazz he picked people out of the audience to paint their portraits with his piano. How lucky was I to b

For change to exist as a possibility in this reality we must have privacy. Freedom of thought, of expression, of association are all predicated on privacy as the space to construct epiphanies into narrative. Absent privacy, change in our wo

To be clear, I wasn't asserting that Eth was less valuable as a result of the DAO reorg (quite the contrary actually). I was merely pointing out that a reorg occurred. Thank you for the education on the bitcoin reorg, I didn't act

This is canon and dates to the original DAO. A quick google on DAO crisis should give you a bunch of reading material. Compare that to the time Binance lost $500M in BTC and contemplated doing a chain revert because it would be way cheaper

Edit 3: See my nested child comment. My understanding (from a 2010 conversation with a friend who was deep in btc) was that there was a time where bitcoin scripting could cause transactions to appear onchain that would look valid to a novic

Who would ever use dropbox if you can use FTP on Linux? It's obvious that Signal is going to release stories. It will just be in a privacy protecting manner when they're ready.
