.Jim Miller found an insecure Fiat-Shamir transformation in Incognito Chain’s aggregate bulletproofs that could have allowed attackers to forge range proofs, mint arbitrarily large tokens, and drain millions of dollars in user funds without detection. blog.trailofbits.com/2023/08/02/a-m…
Kobi Gurkan Fede’s intern 🥊 oskarth Here’s Nova’s folding performance for sha256 reproduced by others: hackmd.io/u3qM9s_YR1emHZ…. Summary: folding is as fast as starky and 100x faster than plonky2. This is one benchmark (we need more!) and Nova needs parallel proving (a la ParaNova). HN will make folding even faster!
if you enjoyed this NTT 101 (honestly, great read), you should definitely check out Yuval Domb NTT 201 book github.com/ingonyama-zk/p…
Using Nova over secp/secq, proving time for 300 aggregated secp256k1 sigs is clocking at 8.44s on my mac. I ported it to wasm, you can try it from your browser - tested on desktop chrome. Writeup: hackmd.io/mArMuUx5TC2LEc… App: …browser-ecdsa-web-dmpierre.vercel.app Repo: github.com/dmpierre/nova-…
Paul Gafni @tracecrypto1 RISC Zero I'm a bit confused with respect to "You need to send them a witness that's potentially tens of gigabytes". In the picture, the prover's input is 50MB (which I'm assuming is the witness size?). How did we go from 50MB (current scheme) to "tens of GB" (under folding schemes)? 1/2
