Pi Squared Docs
Welcome to the Pi Squared Docs. This is your starting point to explore FastSet, the new settlement protocol built for the scale of AI, digital assets, and decentralized applications.
What is Pi Squared?
Pi Squared (Pi²) is building FastSet, a next-generation verifiable settlement protocol designed to power high-frequency, high-scale applications without the overhead of blockchains.
FastSet combines cryptographic trust with real-time performance, allowing millions of claims to be processed in parallel, without requiring global ordering or consensus.
From decentralized payments and verifiable computation to AI-native value flows, FastSet offers a fast, flexible, and verifiable foundation for modern decentralized systems.
Our Mission
At Pi Squared, our mission is to unlock a new era of verifiable, speed, and decentralized infrastructure, without the bottlenecks of traditional blockchains.
FastSet enables this by rethinking settlement from the ground up:
In traditional blockchains, every transaction must be added to a single global ledger in a fixed order, which means all validators must agree on the same sequence before anything is considered final. This is slow and inherently sequential.
FastSet breaks this bottleneck by eliminating total order. Instead of trying to globally coordinate every claim, FastSet assumes most claims are weakly independent—that is, they don’t conflict and can be processed in any order.
Because of this, validators don’t need to communicate with each other or reach consensus. Each one processes incoming claims locally and concurrently, settling them as soon as they’ve been validated. This architecture enables massive parallelism, allowing FastSet to scale naturally with application demand.
Why the name "Pi Squared"?
Pi Squared means Proof of Proof, which stands for zero-knowledge proof of mathematical proof. It is one of our earliest, signature, and unique technologies.
Our Technologies
We pursue our missions by delivering three technologies.
Together, these technologies enable high-throughput, provable, and programmable infrastructure that works across chains, ecosystems, and execution environments.
