Because if you don't trust it you can run the server yourself and see if the behavior is correct AND over time as we move to a world where servers become better able to verify the code they're running, we can improve the trust mod

MobileCoin != Signal. I literally do not work for Signal.

Whoa... I don't work for and have never worked for Signal. Feel free to ask Moxie if I have ever worked for Signal and the answer will be an abject "no". I think it's worth meditating on the tradeoffs of your system desi

I would bet almost any amount of money this isn’t going to work. In any mesh network, the overhead of coordinating nodes dominates network traffic. This is before you even begin to think about the terms of service violations for all of thes

I found a pretty serious bug in a major service provider’s 2fa practices. The first time I reported it, they told me I was wrong. The second time I reported it, they actually tried to reproduce it and had an “omgwtf” moment. They closed it

I hate this language of “so and so isn’t a technologist”. You don’t need to understand how a compiler works or grok segfaults to see the future. It’s obvious if you’re running a big data center yourself that you’d rather pay someone else to

I was a non-engineering background PM (I dropped out of high school). I can tell you about what I didn't know early in my career that was painful for me then (and something I've internalized hard now): It's ok to say "I

Without going too far down a rabbit hole, I think protocols like RAFT are fine for systems where you explicitly trust all of the machines in the network. That being said, designing with "I trust all machines in my network" as a co

This makes sense, but I still think it’s really hard to formally verify immutable code against a mutable VM. Your code can be correct today but the VM can change tomorrow.

Just to add some thoughts here: I’ve interviewed people who were google L7+ (IC) a couple of times who weren’t very good engineers, at least on the work sample stuff. I’ve found that the highest correlation to performance in senior engineer

It’s risk management. Some products just have greater risk associated with them.

I think Alice and Carol need knowledge of 2 tx with Bob to coordinate a common ancestor; that's it. If you imagine the ledger like a deck of cards, there is probably a point where all txo's are shuffled (and we can likely make a c

Let’s assume Alice is an antagonist coordinating with Carol to unmask bob. How many self to self tx does bob need to do to hide from Alice and carol?

Privacy of zcash depends entirely on the setup. Please reread the paper.

Zksnarks is an incredible pile of research. It’s actually stunning. Out of band blinding factor transfer is interesting, also relay/mix nets are interesting. I think it’s all a super cool area that’s worth studying closely.

The trusted setup is the major problem with Zcash, but it’s much more private than MW (assuming you believe the setup). I’m not gonna spend a lot of time arguing on here, but I think it’s worth closely studying these systems as they’re fasc

When thinking about a cryptocurrency, there are a bunch of different attack surfaces (to name a few): * client (wallet) * network from client to node (network) * node * network node to node (consensus) * ledger Each one has a different atta

You need different sets of skills at different times. Peter Thiel eloquently articulated this as “before you can have a company vision, you need a company mantra”. In the beginning the work is about instantiating the product into the world.

The well-articulated tension here is that perfect privacy is ungovernable but zero privacy is undesirable.

I watched a driver-intervention near-crash today on 16th street with cruise where the car sped up and swerved into oncoming traffic across a double yellow to avoid a car backing up that was obvious to the human driver. It's only luck t

To be clear, there are different levels for managers and engineers. An L7 engineer is a seriously dope engineer (like the kind of person you'd want to found a hard technical company with; think low-level problems like DMA). An L7 manag

It’s weird to think that I would find it strange if Apple acquired a company like Shazam and left the ads on, isnt it? In a day and age when all of their competitors are turning to ads to increase revenues, Apple is making great customer ex

Perhaps strange to most of us, $1000+ is not near the full price a VIP package might bear in the current market.

It's subtly more complicated than this. There's the price people are willing to pay before something is "sold out" and exclusive, and the price people are willing to pay to get access to an experience they can't oth
