TL;DR
The paper introduces Valida ISA, a specification optimized for zero-knowledge virtual machines, aiming to facilitate efficient proof generation and execution in zkVM environments.
Contribution
It provides a clear, formal specification of Valida ISA, supporting implementation and formalization efforts for zkVMs and compiler toolchains.
Findings
Defines unambiguous semantics for Valida programs
Supports formalization and implementation of zkVMs
Aids in developing efficient zk-proof systems
Abstract
The Valida instruction set architecture is designed for implementation in zkVMs to optimize for fast, efficient execution proving. This specification intends to guide implementors of zkVMs and compiler toolchains for Valida. It provides an unambiguous definition of the semantics of Valida programs and may be used as a starting point for formalization efforts.
