Ethereum News Update: Transforming Blockchain Privacy: Zama and Kakarot Unite to Achieve Over 10,000 Private TPS

Paris, France – Zama, a company focused on cryptographic solutions and Fully Homomorphic Encryption (FHE) for blockchain, has announced the acquisition of KKRT Labs, a research group specializing in zero-knowledge (ZK) technology. This acquisition, revealed on November 5, 2025, is intended to boost both scalability and privacy on public blockchains. By merging Zama’s FHE capabilities with KKRT’s ZK rollup innovations, the companies aim to achieve over 10,000 confidential transactions per second (TPS) on networks such as

and , as reported by .

KKRT Labs, also called "Kakarot," is recognized for its expertise in advanced proving systems and modular rollup frameworks. Supported by Ethereum co-founder Vitalik Buterin, StarkWare, and Lambda Class, KKRT has built scalable ZK engines for Ethereum-compatible platforms. Zama’s CEO, Rand Hindi, stated that this acquisition "deepens our technical expertise in ZK rollups and accelerates our progress in high-performance privacy," setting the combined company up to lead in private on-chain financial applications like stablecoin transfers and DeFi, according to a

.

Following the merger, KKRT’s core team will remain in place, and its development plans will be integrated with Zama’s overall strategy. Both organizations are committed to open-source development and building privacy-centric infrastructure. Vitalik Buterin commended Kakarot’s impact on Ethereum’s cryptographic progress, including work on ZK-EVMs and privacy-focused client-side proofs, as highlighted by Blockchain Magazine. Eli Ben Sasson, co-founder of

and CEO of StarkWare, emphasized Kakarot’s talent for turning experimental ideas into scalable products, describing the acquisition as "crucial support" for Zama’s vision, according to The Block.

Zama’s main protocol introduces a privacy layer to current blockchains, using FHE to allow secure data computation without exposing the underlying information. After raising $150 million and reaching a $1.2 billion valuation, Zama plans to grow its research division and incorporate KKRT’s modular technologies into its platform. Clément Walter, KKRT Labs’ co-founder, said the collaboration will "bring high-speed, low-latency confidential finance on-chain," helping to overcome a major obstacle to blockchain adoption, as noted by Blockchain Magazine.

This acquisition highlights the increasing need for privacy-enhancing solutions in decentralized finance. By joining forces, Zama and KKRT Labs are preparing to address the challenges of scalability and privacy, with the potential to significantly influence the future of public blockchain networks.
