ZK Industry News: September 4th to 10th, 2025

✨ ZK-Newsflash! ✨

We're bringing you industry highlights each week so you can stay aligned with the latest developments in ZK.

Here's what happened from September 4th-10th, 2025.

StarkWare has set a record proving the entire Bitcoin block header chain in just 6.5 hours for only $13.5

They have proven 16 years of blockchain history worth $2 trillion. The verification process takes only a few milliseconds, even on small devices, thanks to STARK technology.

Upbit plans to launch Ethereum L2 using OP Stack

Upbit, a leading South Korean crypto exchange, is preparing to deploy an Ethereum Layer 2 network using the OP Stack framework, based on Optimism's open-source technology. This aims to lower transaction costs, boost processing speeds for users, while maintaining compatibility with the Ethereum mainnet.

ZisK in-browser verification is live on Ethproofs

This project allows direct verification of STARK proofs in web browsers and Node.js environments, accelerating Ethereum’s transition to open-source snarkification.

Irreducible is pivoting from custom hardware to high-performance software, and has released its new proof system, Binius64

The announcement includes lessons from three years in hardware, and emphasizes that its mission remains to accelerate the verifiable Internet.

On the other hand, Binius64 is a CPU-optimized proof system with several improvements over Binius V0.

Ronin is integrating with Optimism’s OP Stack, transitioning from a sidechain to a full Ethereum L2

This will bring faster transactions, stronger security via Ethereum, and more funds to the Ronin Treasury.

Bonus track: We shared an X article titled 'zkVMs, Circuits, and the Optimization Game' written by our co-founder and CTO, Mauro Toscano

In this new post, he explores the engineering trade-offs between ZK circuits and zkVMs, discussing how to approach the design and building of these systems.
