The @HouseofZK Weekly Newsletter From fresh reports on ZK privacy and proof verification to ePrint highlights, the recent @eth_proofs call, and our upcoming in-person workshop in San Francisco, this update covers a wide spectrum of ZK activity from the past week. We’ve compiled everything you need to stay current in one place 👇

House of ZK Radio & Broadcasts This week, we released three new feature conversations: 1. Eric Vreeland (CSO at Polyhedra) - We sat down with @vreeland, Chief Strategy Officer at @PolyhedraZK, to explore the architecture of performant proof systems, developer onboarding with ProofCloud, and the move from bridging to verifiable AI. Spotify: YouTube: 2. The Succinct Special with Uma Roy - In this broadcast, @pumatheuma (CEO of @SuccinctLabs) joined us to reveal the latest announcements from the Succinct ecosystem and discuss all things zkVMs. 3. Bitcoin Economy Interview with Michael Terpin - We released a new recording from the Bitcoin Economy Conference in Las Vegas, where we sat down with the Crypto Godfather himself, @michaelterpin - founder of @BitAngels, Transform Ventures, and now advisor to @GOATRollup. Topics include Bitcoin’s four-season cycle model, the rise of programmable Bitcoin, a vision for a freedom-first financial system, and much more.

Ethproofs Report: Call #3 Recap - The third @eth_proofs call delivered key insights into @ethereum's deepening integration of zkVM infrastructure, GPU prover acceleration, and the roadmap toward scaling the Layer 1 to 1 gigagas per second. Full recording: Highlights: 🔹zkVM Tracker: @drakefjustin shared tracker updates, including GPU prover tracking, @ProjectZKM’s zkMIPS → Ziren rebrand, @0xLita’s open-sourced Valida, and @ziskvm's integration with Ethproofs. 🔹Valida (by @PlatonicMorgan, @lita_xyz): v0.1.0 released with multi-segment proving and GPU prover development via Nim-to-CUDA. Not yet integrated with Ethproofs. 🔹Pico (by @succinct_li, @brevis_zk): STARK-based zkVM now 2× faster on CPU and up to 20× on GPU vs competitors. Open-sourcing planned post multi-GPU support. 🔹@ethereumfndn: Introduced a new zkEVM client team targeting validator-side ZK clients post-Pectra. Hardware constraints, licensing, and zkVM security standards outlined. 🔹Benchmarking (@ignaciohagopian): Introduced zkVM test frameworks for opcode stress, gas cost linearity, and public proof throughput data. 🔹Security (@codytouchgrass): Focused on underconstrained circuit detection via tools like Pyus (by @VeridiseInc) and circuit analysis for Plonky3. 🔹Website Updates (@eth_proofs): New GitHub issue template, onboarding board, “Coming Soon” tab, and proof speed sorting. 🔹Gigagas Scaling (by @drakefjustin): - Latency: Same-slot proving, ahead-of-time trace generation, and fast APIs - Security: Multi-zkVM diversity, slow-fast prover pairing, K-of-N verification - Liveness: $0.0001/megagas target, proof generation via residential GPU setups - Roadmap: EIP-4844 → EIP-7594 → EIP-7685 → EIP-7697 → EIP-7730 → EIP-7938 The Ethproofs Call #4 is scheduled for August 2025.
