Uninight was awesome and the venue was beautiful! Really enjoyed presenting this impromptu roadmap session and talking about AUCIL which is joint work with @SarishtW, @kartik1507, @0xFanZhang, @soispoke, @barnabemonnot and @luca_zanolini Quick thread!
Vintage car lights lit up our UniNight - the Sidecars Roast🔥 Challenge 1: Think outside of the 🗺️ what if we have perfect crypto and trsutless TEEs today, what part of this version of the Ethereum Roadmap towards decentralization can be streamlined or completely rewritten?…
After two years of R&D, five testnets & integration plans with >20 chains, we’re excited to announce the Espresso Network is now live on mainnet! This launch is a major milestone, both for our team and along the path to making Ethereum composable again. Read on to learn more ☕️
How should a blockchain keep a secret? 🔑 I recently spoke about this @ the Dagstuhl Seminar on Next-Generation Secure Distributed Computing organized by @cczurich, @aniketpkate, @julian_loss & @kartik1507 (Why? On-chain randomness, encrypt-to-a-smart-contract & more.)

What is verifiable information dispersal?
Decentralized thoughts on **Verifiable Information Dispersal** With @kartik1507, Ling, and Gilad 🔥 decentralizedthoughts.github.io/2024-08-08-vid/
My advice to the new wave of crypto researchers: Think rigorously. While we don't need to follow the hierarchical research model of academia, the primitives need to be rigorous and the protocol that uses them must also be rigorously verified. Don't take the easy way out.
Something that's not widely understood about slashing in restaking, is that it can be impossible to identify every malicious party in a BFT failure. @sreeramkannan, @kartik1507, @GaryWang523 and others wrote this paper in 2020 on exactly this challenge arxiv.org/abs/2010.06785
This blog post (decentralizedthoughts.github.io/2024-05-23-sai…) explains the core ideas behind Sailfish, a latency-efficient DAG-based protocol. We also present our view on DAG-based vs leader-based protocols. Paper: eprint.iacr.org/2024/472.pdf With lead author @nibeshrestha2 and Rohan and @aniketpkate
