ZK Industry News: November 27th to December 3rd, 2025
✨ ZK-Newsflash! ✨
We're bringing you industry highlights each week so you can stay aligned with the latest developments in ZK and Ethereum.
Here's what happened from November 27th to December 3rd, 2025.
LambdaClass is launching ethlambda, a minimalist lean Ethereum consensus client
Just like with Ethrex, a Rust-based execution client, Federico Carrone highlights the importance of minimalism and code readability in software engineering. This new project underscores Lambda’s commitment to open-source development and Ethereum’s long-term vision.

Last year I announced that we started @ethrex_client, a minimalist and fast Rust execution client. It is now running in production as one of the smallest and most efficient clients in the network. We delivered in the… https://t.co/njZzjxyIDQ pic.twitter.com/aASEwaJl5j
Aligned published an article on the evolution of zkVMs and real-time proving for Ethereum
The article covers key milestones, recent advancements in zkVM performance, and Ethereum's roadmap towards achieving real-time proving with zero-knowledge proofs. Key breakthroughs have significantly reduced proof costs and improved scalability, bringing Ethereum closer to its long-term goals.

Federico Carrone and Roberto Catalan explore how Ethereum addresses the missing institutional layer of the internet
The article discusses how the internet transformed communication but lacked institutions to manage digital ownership. Ethereum addresses this gap by embedding property rights and contracts in software, enabling decentralized, verifiable systems for ownership and transactions.
Together with @rj_aligned, we’re developing a series of articles that articulate our mental framework on several topics. We frequently need to explain how we view the technologies we’re building at @class_lambda and @alignedlayer, so we’re creating material to reference.

Fusaka has been activated on Ethereum Mainnet
This upgrade introduces 13 EIPs that enhance blob scaling, performance, and user experience. Key upgrades include PeerDAS, enabling 8x data throughput for rollups, UX improvements through the R1 curve and pre-confirmations, and preparation for L1 scaling with a gas limit increase.
The Fusaka upgrade is today.
