Thomas et al. explained the Valida instruction set architecture in their paper, designed for zkVM implementation, aiming to optimize fast and efficient proof execution. Thomas等人在论文中讲解了Valida指令集架构,专为zkVM实现设计,旨在优化快速高效的执行证明。
Notes
Instruction Set Architecture (ISA) optimized for zkVMs to enhance ZK proof efficiency
No general-purpose registers; directly accesses RAM via stack offsets to reduce instruction count
Modular design; base version consists of specified chipset components
Harvard architecture, 32-bit little-endian, with only FP and PC as special-purpose registers
Interacts externally via read-only input and write-only output tapes, ideal for blockchain verifiable computation
Compared to RISC-V, significantly reduces SNARK proving overhead and improves performance
