In this edition, we are proud to share the highlights from September, which witnessed major developments including the release of our latest benchmark report, research articles, and key partnership activities.

In this work, we begin to publish a general and fair zkVM benchmark framework based on previous work by a16z, providing a comparison on proving time and energy cost between ZKM (zkMIPS) and other zkVM projects, like RISC Zero (R0) and SP1.

What constitutes a proof of transaction?

To accomplish cross-chain asset transfer, most of the solutions currently available are based on a bridge, a separate, intermediate entity, which is typically trusted with holding these assets during some period of the transaction. This trust assumption is undesirable since it provides a large opportunity for attack. In this post I will explain that, assuming the existence of a zkRollup, one can implement cross-chain asset transfer without the need for additional trust assumptions (such as a bridge).

Bitcoin’s transition from a speculative asset to a globally dominant financial system is approaching an inflection point. Developments

This article provides a broad overview of our ongoing initiatives, showcasing the breadth of our work and offering a glimpse into the future.

STARK (Scalable Transparent Argument of Knowledge) is a kind of proof system introduced in 2018 by Eli Ben-Sasson and his colleagues, offering better scalability and transparency than traditional SNARK systems. STARK operates by transforming complex computations into arithmetic circuits, which are then represented as polynomial evaluation problems. To conceal intermediate results during computation, polynomial commitments are employed while allowing the verifier to sample and check these results. By applying low-degree extensions, intricate computations are reduced to verifying low-degree polynomials, before the efficient interactive proof protocol, FRI, is used to check if a polynomial has a low degree. This technology has broad applications in enabling privacy preservation and verifiable computations.

zkGM and welcome to the June edition of the ZKM Newsletter ☀️.

Following the recent release of the updated zkMIPS paper by ZKM Research, we hope to address the key questions that followed from our community. Here, we present a broad Q&A with insights into the paper’s updates and their significance.

ZKM is pleased to announce the release of its exclusive Proving Service, providing developers with access to high-performance servers that are equipped to efficiently handle the intensive computational requirements for generating zero-knowledge proofs. The service is optimized specifically for zkMIPS, ZKM's specialist zkVM software for facilitating integration of ZKP capabilities into various applications.

Here, we announce the publication of the latest paper from ZKM Research: ‘zkMIPS: A High-Level Specification’. This substantial update of the previous version corrects the discrepancies between the original documentation and the present state of the zkMIPS codebase, providing a more accurate foundation of information to aid the ZKM developer community with their contributions.

​​We were delighted to announce a successful $5M Pre-A funding round in November 2023, led by OKX Ventures, with support from Polygon Ventures, Crypto.com, Amber Group, Leland Ventures, Waterdrip Capital, DFG, JSquare, Contribution Capital, and Metis Foundation 🔥

Network effects, as defined by Andrew Chen(a16z) in the book, The Cold Start Problem, describes what happens when products get more valuable as more people use them. As a founder of a hardcore infrastructure project building a general-purpose zkVM to unify liquidity across blockchains, how to achieve network effects for a lower-layer infra project is what I think about all day and night.

Historically, the greatest technological and corporate endeavors have been driven by a purpose that extends beyond the immediate objective of profit maximization. The companies run by Elon Musk are a great example. Consider SpaceX's ultimate mission to make humanity a multi-planetary species, or the objectives of Tesla,

ZKM is building the Quantum Network using Entangled Rollups to enable Universal Settlement.

Hello Q2! Our team is beyond excited to begin the new quarter, and we grow stronger everyday. We grew slowly after our initial launch in July 2023, but during Q1 of 2024 our community exploded to nearly 50,000 members. With this newsletter we hope to communicate our gratitude and appreciation to our community and partners who have been such an important part of the journey.

TL;DR: zkMIPS proves the correct execution of a MIPS program in five steps: it (1) divides the program in segments, (2) divides the instructions of each segment in four module tables, (3) proves instructions from each module table independently, (4) proves instructions from each segment is contained in one of its tables, and (5) recursively proves that the sequence of segment match the program execution. Step 3 is written as a STARK, step 4 is a logUp proof written as a STARK, and step 5 as a PLONK proof. All proof steps are implemented with the Plonky2 library. Optionally, one can generate a final Groth16 proof to verify the program execution on-chain.

We recently introduced a new trust-minimized multi-chain Interoperability infrastructure called Entangled Rollup.‍In this work, we implement an interoperability protocol by judiciously entangling the underlying primitives under standard security assumptions of zkRollups, leveraging our state-of-the-art recursive zkVM (zkMIPS). ‍The Entangled Rollup protocol is trustless, and a step forward to addressing liquidity fragmentation, in addition to simplifying the user and developer experience as major adoption barriers of the multi-chain world. ‍

It’s safe to say that February 2024 was the month that truly put ZKM on the map! After months of intense preparation and ardent building in relative stealth, we revealed several mouth-watering new developments in the build-up to our genesis launch of the House of ZK, which lit-up EthDenver!

We are thrilled to announce the launch of our zero-knowledge virtual machine (zkVM) Alpha Testnet.

We’re extremely pleased to be able to introduce ‘Delphi: sharing assessments of cryptographic assumptions’, an advanced research initiative developed by Jeroen van de Graaf and Arjen K. Lenstra.

January was a month of intense preparation — not only are we on the verge of our long-awaited testnet launch, but Eth Denver is also on the horizon and our ‘House of ZK’ hacker house is lining up to be something very special.

We’re ecstatic to move into the New Year with everything that’s coming in 2024. ZKM ended 2023 with tremendous gratitude and appreciation for our community — we couldn’t have had such a successful year without you!

The Science of Blockchain Conference (SBC 2023) is held annually at Stanford University. The local ZKM team attended, and of the attending team Chief Research Advisor Jeroen van der Graaf shares his experience and gives his insight of the events and the seminars with commentary:

August marked another month of building our universal-purpose zkVM. Let’s look back at all the happenings here at ZKM. Hack to the Future Livestream

In our article discussing the road to Hybrid Rollup technology, we talked about the evolution of Ethereum’s scaling struggle. Within that discussion, we saw how an elegant and practical solution finally emerged: a layered blockchain design, with Layer 1 as the main chain dealing with only consensus and data availability, and Layer 2 as a Rollup to provide offloaded computation validation for all blockchain users, thus creating a scalable blockchain solution.

Using zkMIPS, a client can outsource a program written using the MIPS instruction set, have it executed, and in addition to getting the result, receive an easily verifiable proof that this result is correct. The software component that creates this proof is called a zkVM.

Now that we have described the broader questions of ZK proofs security, let’s continue with Question 2. In the analysis of a two-party

Understanding the security properties of ZK proofs is a monumental challenge. Since we are building a universal-purpose zkVM (called zkMIPS, because it combines zero-knowledge proofs with the MIPS instruction set), it’s vital that we consider security within every line of code that we develop.
