Looking forward to talking about accountable liveness at SBC at 1:30p today! TL;DR: x.com/jneu_net/statu…

Don't miss Aditi's SBC talk today at 10:30 !

I'll be speaking at the Ethereum Research Funding Forum today, on "when is a blockchain expensive to attack", covering both safety and liveness attacks. For safety attacks, we can formalise when a protocol is expensive to attack (see arxiv.org/abs/2405.09173, joint work with

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 🧵

Bitcoin tolerates drastic miner churn—as long as a majority of hash power is honest at any time. Can proof‑of‑stake achieve a similar property? New paper to appear at AFT 2025, w/ a16z crypto’s Joachim Neu & Toniann Pitassi: eprint.iacr.org/2025/1455

Come do blockchain protocol research with us a16z crypto ! 🧑‍🔬🗽🍎

Later today at AFT, Jovan Komatovic will talk about our paper "From Permissioned to Proof-of-Stake Consensus". The paper gives a generic wrapper that takes any permissioned blockchain protocol and turns it into proof-of-stake version (inheriting fundmental properties of the

1/2 As always, tons of great research seminars last summer a16z crypto, with topics ranging from consensus protocols to mechanism design to zk/TEEs/MPC to governance to MEV. And as always, we're making them publicly available. First two, by Joachim Neu and Ling Ren, just posted!

Tomorrow at CCS Joachim Neu will talk about our Accountable Liveness paper (eprint.iacr.org/2025/693). It's well-known how to attribute blame (slashing conditions) when there is a safety violation. Doing the same for liveness violations is harder, but we pin down when it's possible.

We’re excited to share our 2025 State of Crypto report. This year’s story: the maturation of the crypto industry — with growing institutional adoption, the rise of stablecoins, better infrastructure, new consumer experiences, and long-awaited regulatory clarity. Read the full

With the continuing government shutdown in the US, SNAP benefits are now paused -- which makes it more important than ever to support food aid organizations. So I've created "Fibonacci Harvest." It's cheap -- .0033 ETH per edition, roughly $12.50 -- and all revenue raised will
