RISC Zero, a ZK infrastructure company that raised $40 million, has officially launched zkVM 1.0 today—the production-ready version of its general-purpose zkVM. The zkVM赛道 now has players ready for production use, yet while many may frequently hear the term "zkEVM," few understand what exactly a "zkVM" is, despite the one-letter difference. This article introduces the advantages of the instruction set adopted by most zkVMs; for more information on zkVMs, refer to this article.
zkVMs are more general-purpose than zkEVMs, unlocking the ability to write programs in general programming languages and code beyond Solidity libraries. They have now become a hot sector. Leading projects in this space—RISC Zero, Succinct, Lita, and Jolt (backed by a16z)—all build on the RISC-V instruction set. What advantages does it offer? Why will the future of zkVM be based on the RISC-V architecture? And why is @rv_inc building tools to enable formal verification at the RISC-V level?
The RISC-V instruction set offers the following key advantages:
Open and Extensible Architecture:
RISC-V is an open-standard instruction set architecture (ISA), free for any kind of use, highly adaptable, and customizable. This allows zkVM developers to specifically tailor the architecture for proof generation, optimizing performance and efficiency. Why has Linux captured the largest share of server systems? The word "free" truly matters!
Modularity and Flexibility:
The modular nature of RISC-V enables zkVM developers to implement only the functionalities they need, avoiding unnecessary complexity and overhead. The benefits of modularity have been emphasized enough in this cycle, so we won't elaborate further.
Standardization and Ecosystem Support:
RISC-V boasts a rapidly growing ecosystem with broad toolchain support—including compilers and debuggers. For instance, @rv_inc is developing formal verification tools targeting the RISC-V ISA. A fast-evolving ecosystem means vast room for innovation and sometimes synergistic, two-for-one effects.
Efficient Proof Generation and Verification:
The simplicity of RISC-V’s design contributes to more efficient execution of the complex algorithms involved in zero-knowledge proofs. By leveraging the RISC-V instruction set architecture, "zkVM" can achieve better performance in speed and resource utilization—critical for proof aggregation.
Security and Formal Verification:
RISC-V’s clear and well-defined architecture makes it easier to apply formal verification techniques, which are crucial for ensuring the security and correctness of zkVMs. Using RISC-V, developers can leverage formal verification tools and methods to build more secure zkVMs.
Cross-Platform Compatibility:
RISC-V’s compatibility across various hardware platforms—including x86, x64, and ARM (commonly found in Windows, Mac, and various embedded devices)—means zkVMs can be deployed across a wide range of environments. This flexibility is key to widespread adoption of proof aggregation solutions, enabling seamless integration into different systems.
Language Universality:
RISC-V does not natively include concepts like wallet addresses or other blockchain structures. The instruction set primarily consists of operators that move data between memory locations and perform mathematical operations on data. Moreover, compared to the EVM, the underlying RISC-V emulator allows programmers to write zkVM programs in languages such as Rust, C/C++, and Go. This means zkVM developers can leverage existing libraries built within those language ecosystems—for example, Rust libraries developed for Solana.
As the concept of "general-purpose computing" grows increasingly popular, what sparks will zkVM bring to the intense VM competition (MoveVM, SVM, EVM, zkEVM...)? Can it achieve significant adoption and establish a solid foothold? The first player, RISC Zero, has already made a dazzling debut. The rest is up to time to decide.
