Highly recommended! Direct quote from my thesis: "Discussions during my stay at a16z crypto were a significant inspiration for the research vision in this dissertation."
We've had 25 research interns over the past four summers @a16crypto, many of whom are now among the most visible researchers in the space. If you'd like to be a part of the summer '26 cohort, apply here:

1/ Jolt just got a 6× speedup. We now prove over 1,000,000 RISC-V cycles/sec on a 32-core CPU and over 500,000 cycles/sec on a MacBook, with proofs of about 50 KB. Here’s what’s new 🧵

Today at SBC @jneu_net will talk about our Accountable Liveness paper ( https://t.co/bZmEETdpU5). Attributing blame when a blockchain suffers liveness violations is harder than for safety violations. In this paper we pin down when it's possible. Joint work also with
eprint.iacr.org
Safety and liveness are the two classical security properties of consensus protocols. Recent works have strengthened safety with accountability: should any safety violation occur, a sizable fraction...

🚨 Interesting update to our model of LVR with fees! Our updated paper with @ciamac @Tim_Roughgarden now also captures gas fees. Most importantly, we prove that lower gas fees **help LPs** by reducing LP losses. 1/2
