Is there a **reliable** implementation of Labrador in rust? This is the only one I found. Is it good? cc Albert Garreta | Hiring | Nethermind github.com/NethermindEth/…

Join us for the Lagrange Science Fair this Thursday, July 31st in anticipation of SBC 2025 (Science of Blockchain Conference)! Hear from top researchers from Yale University, Stanford University, Cornell University, UC Berkeley, and Penn on new innovations in blockchain & AI: lu.ma/wpoxatcc

Speaker Spotlight: Alireza Shirzad Alireza (Ali) Shirzad is a Lagrange research intern & PhD student at @penn advised by Pratyush Mishra He is currently designing proof systems and SNARKs—and will share new work on SNARK optimizations




Very cool to see the @aptos keyless ZK proof re-implemented with Garuda (instead of Groth16) by Alireza (Ali) Shirzad, Pratyush Mishra and Michel Dellepere! 😎 Next: can we get an equifficient PCS without a trusted setup? 🥹


And that's a wrap on another spectacular SBC 🎬 We were honored to participate (yet again!) in cutting-edge research at the intersection of cryptography, decentralized systems, and real-world impact. Coming soon to our Youtube: 〰️ Dynamic zk-SNARKs - Weijie Wang PhD, Yale University 〰️




Back to actual research… We present a family of space-efficient sumcheck algorithms, and show that they are optimal! 🍹 Joint work with Anubhav, Ale, Elisabetta Fedele, Pratyush Mishra, Tushar Mopuri and Andrew Z 📚: ia.cr/2025/1473 🧑🏻💻: github.com/compsec-epfl/s…
