TLDR: Pi Squared has announced that its FastSet Protocol has achieved over 100,000 transactions per second (TPS) with sub-100 millisecond finality on conventional hardware. This breakthrough sets a new benchmark for fast, verifiable, and decentralized settlement across chains, applications, and AI agents, addressing critical scalability and trust issues in Web3 infrastructure.
Pi Squared, a leading innovator in Web3 infrastructure, has unveiled a significant advancement with its FastSet Protocol, demonstrating a remarkable performance of over 100,000 transactions per second (TPS) and sub-100 millisecond finality. This achievement, publicly showcased on August 12, 2025, positions FastSet as a new standard for efficient, verifiable, and decentralized settlement.
Unlike many high-throughput Layer 1 and Layer 2 solutions that necessitate expensive, specialized hardware, FastSet distinguishes itself by achieving this performance on conventional hardware, specifically 24-core CPUs with 256 GB of memory. This makes validator operation highly affordable, with machine costs potentially under $1,000, significantly lowering the barrier to participation and fostering broader decentralization. The company aims to further scale its mainnet performance to an ambitious 1 million TPS.
Grigore Rosu, President and CEO of Pi Squared, highlighted the initial skepticism surrounding such high performance figures, stating, “When people hear 100,000 TPS less than 100 milliseconds, first of all they don’t believe us. Then we show them all the evidence, the papers, and everything, and they say wow that is the next step.”
FastSet is designed as a next-generation verifiable settlement protocol, purpose-built for digital assets and artificial intelligence at scale. It operates as a decentralized network, not a traditional blockchain, leveraging formal semantics and the K Framework. This innovative design allows it to break the conventional total ordering constraint of blockchains, enabling theoretically unlimited transaction speeds and ensuring every transaction is independently provable without relying on trust assumptions.
This protocol directly addresses the fragmentation, latency, and trust bottlenecks prevalent in today’s Web3 infrastructure. It facilitates parallel, verifiable, and cross-chain settlement without the need for bridges or centralized coordination, allowing applications, agents, and protocols to interact seamlessly across ecosystems. Key applications include real-time financial services like high-frequency trading and settlements, gaming, and particularly, AI. Rosu noted, “We’re discussing with several AI agent companies… the AI agents communicate with each other, they have protocols on how they communicate, they pay each other. So all those need a very fast network to send micropayments.”

The announcement follows the recent launch of Pi Squared’s VSL Devnet, its Verifiable Settlement Layer’s first live environment. Having secured $12.5 million in seed funding last year, Pi Squared is currently undertaking an additional strategic funding round to accelerate its mission of resolving the scalability, fragmentation, and trust issues that current blockchain infrastructures struggle with.
