AI overview

Updated

Pi Squared Inc. is a Champaign, Illinois verifiable-computing company founded in 2023 by Grigore Rosu, the University of Illinois computer science professor behind the K framework and Runtime Verification. It builds zero-knowledge proof infrastructure that verifies the correct execution of any program in any programming language or virtual machine, using a 'Proof of Proof' approach and a universal ZK circuit derived from formal semantics rather than a language-specific rewrite. Its blockchain architecture, the Universal Settlement Layer, lets computations be expressed in any high-level or VM language without compilers or translators. The team now ships Fast, a parallel-settlement payment system aimed at machine-speed agent-to-agent transactions.

What sets it apart

A language- and VM-agnostic proof system: instead of compiling programs into a proprietary ZK instruction set, it generates zero-knowledge proofs of the mathematical proofs implied by a language's formal semantics, so correctness guarantees extend to any language or virtual machine from one minimal universal circuit.

Universal Settlement Layer (USL)

Blockchain infrastructure

A modular blockchain settlement architecture backed by Pi Squared's universal ZK circuit, letting computations be expressed and verified in any high-level or virtual machine language without compilers or translators.

  • Proof of Proof: zero-knowledge proofs that verify mathematical proofs of program execution
  • Universal ZK circuit driven by a language's formal semantics rather than a fixed instruction set
  • Language and virtual machine agnostic verification, with no compiler or translator step
  • Modular architecture with deterministic validation and minimal trust assumptions
