I really think that all of this DeFi stuff is playing with fire. If these tools scale large enough, it's easy to imagine breaking the right link in the system at the right time to cause catastrophic failures. Remember that all complex

Just out of curiosity, don’t you think that in strictly versioned software, ie software that everyone has to be running the same version at runtime for it to work, you could enforce such versioning primitives? I think there’s a world where

Rust is great. While working with Secure Enclave’s isn’t the same as a microcontroller per se (many SE’s work in tandem with powerful chipsets), at MobileCoin we’ve found a lot of benefits from using Rust. Rust appears to provide the abilit

This is a thing I think people constantly underestimate... Intel's cores are not necessarily dramatically more broken than everyone else's chips, they just pay for more auditing and public research.

I went to FORM:ARCOSANTI some years back. It’s a festival at the site curated by Hundred Waters. I will never forget the surreal experience of seeing skrillex do a back to back set with fourtet (those genres still don’t add up). The amphith

Build reproducibility doesn't solve the problem of "how do I know the computer I don't control is actually running the program I think it is?" The only solutions are related to fully homomorphic encryption, which is a wa

There’s no way to do a FHE style system with branching unless all branches are indistinguishable from one another. All branches must execute in the same amount of time, otherwise statistical analysis will leak information. Forget Turing com

I’m not convinced you can do ORAM without a Secure Enclave. If you’re already using an enclave, you don’t need FHE.

It’s more complicated than “do you believe in SE”. There’s a difference between using a SE for storing durable secrets (a bad idea in most implementations I’ve seen) and using a SE for provably destroying a piece of information. The former

FHE style systems are possible if you use a hardware-based encryption approach like a Secure Enclave, but then you have a trust narrative that includes a Secure Enclave. For most use cases this is unacceptable. Note: I work on a system desi

FHE gets brought up all the time. There are great discussions down thread about why this isn’t practical for most use cases. The killer thing is the performance penalty for doing FHE on any dataset of meaningful size. This is because if you

You can get a lot of the benefit of a linear scan using a technique like oblivious RAM but I’m not convinced it’s possible to build such a system without using a Secure Enclave. There are some papers that purport to implement this but once

Would you say that this circuit was fully homomorphic if, for all inputs, the processor appeared to be doing the same work? That is to say? If X = 1 or X = 2 the processor did not appear to “do nothing” but, instead, performed an operation

The whole internet has felt like one big eternal September to me lately. I really do wonder where people go to get their philosophical itches scratched these days.

The media lab has done a ton of research on this. I seem to remember people being able to notice visual latency at 30ms and audio latency at 80-120ms (this is because light is faster than sound).

The problem with hub and spoke is that the hubs hold the social graph and then become the target for censorship. I don't think there are any techniques employed by Matrix to mitigate that threat at this time (please correct me if I&#x2

I understand the goal. I don't understand how a peer P2P system is going to route large groups at scale. I don't think phones are powerful enough to deal with the kinds of routing you need for large scale comms services. In genera

I don't understand what you mean... Even in bitcoin you're still trusting some group with a K of N majority agreeing on some software.
