Lumoz RaaS to Support RISC-V zkEVM: Empowering Layer2 Performance and Scalability Breakthrough

Summary: Lumoz RaaS has launched a RISC-V-based zkEVM support solution, which helps developers quickly deploy zero-knowledge proof applications with pre-built development modules and a compatible toolchain. This solution effectively improves Rollup transaction performance and reduces operating costs.

Background

Ethereum founder Vitalik Buterin recently proposed replacing the existing Ethereum Virtual Machine (EVM) with the RISC-V instruction set architecture. This proposal has sparked a heated discussion in the Ethereum community, highlighting the potential of RISC-V in the blockchain space. Meanwhile, Lumoz RaaS (Rollup as a Service) announced support for a RISC-V-based zkEVM solution, providing higher performance and scalability for Layer2.

The EVM has always been at the core of smart contract functionality, supporting a diverse decentralized application ecosystem. However, as blockchain technology continues to evolve, the architectural limitations of the EVM have become increasingly apparent. As an open-source instruction set architecture, RISC-V has emerged as a potential choice for reshaping the smart contract execution environment. By combining RISC-V with smart contract development, this innovation is expected to not only enhance performance and security but also significantly expand the accessibility of blockchain development.

Why Choose RISC-V?

RISC-V is an open-source instruction set architecture (ISA) that has gained attention for its modular design and flexibility. Compared to traditional proprietary architectures such as x86 and ARM, RISC-V offers the following core advantages:

· Open Source and Free Licensing: No patent restrictions, significantly reducing development and deployment costs.

· Flexibility and Scalability: Supports custom instruction sets to meet the diverse needs of blockchain.

· Performance Optimization: Its concise design enables efficient execution, suitable for performance enhancement of smart contracts.

Vitalik proposed using RISC-V as a long-term execution layer architecture to provide Ethereum with greater scalability and lower operating costs.

Limitations of the EVM

Before understanding why RISC-V is chosen, it is necessary to clarify the shortcomings of the EVM:

· Complexity: EVM's bytecode design is complex, relying on stack operations, which affects execution efficiency.

· Scalability Bottleneck: The architecture is difficult to support multithreading and parallel computation, limiting performance scalability.

· Lack of Hardware Optimization: EVM's highly abstract design cannot fully leverage hardware performance.

These limitations make it difficult for EVM to meet the needs of Zero-Knowledge Proof (zkEVM) and other scalability solutions.

Background and Challenges of zkEVM

zkEVM (Zero-Knowledge Ethereum Virtual Machine) is a virtual machine based on Zero-Knowledge Proof (zk-SNARKs or zk-STARKs) technology, allowing users to verify computation results without revealing specific data. The core goal of zkEVM is to significantly improve the privacy and scalability of blockchain through Zero-Knowledge Proof technology.

Technical Challenges of zkEVM

1. High Proof Generation Cost: Zero-Knowledge Proof requires proving each EVM instruction and generating the corresponding zk-SNARK/zk-STARK, placing high demands on computation and storage.

2. Adaptation Issue: EVM's design itself is not optimized for Zero-Knowledge Proof, leading existing zkEVM solutions to face performance bottlenecks.

3. Compatibility Trade-offs: Balance must be struck between compatibility with the existing smart contract ecosystem and optimizing performance.

Combination of RISC-V and zkEVM

RISC-V provides an ideal hardware abstraction layer that can better adapt to zkEVM's requirements. The following are several technical highlights of the combination of RISC-V and zkEVM:

1. More Efficient Proof Generation

RISC-V's concise instruction set makes Zero-Knowledge Proof generation more efficient. Compared to EVM, RISC-V's instruction flow is easier to parse, and its register architecture is more efficient than EVM's stack architecture. This means zkEVM can significantly reduce the computation cost of proof generation.

2. Customizable Instruction Set

RISC-V's modular design allows for a customized instruction set for zkEVM. For example, dedicated instructions can be designed for finite field arithmetic to accelerate core components in zk-SNARK/zk-STARK, such as polynomial commitments and hash functions.

3. Hardware Acceleration Potential

The open-source nature of RISC-V allows hardware manufacturers to provide dedicated hardware acceleration support for zkEVM, including:

· Application-Specific Integrated Circuit (ASIC): An ASIC chip optimized for zero-knowledge proofs can directly implement the RISC-V zkEVM instruction set.

· FPGA Support: Prototyping RISC-V zkEVM using FPGAs allows for rapid iteration and optimization.

Designing and Implementing the RISC-V EVM Architecture

The design and implementation of RISC-V zkEVM should focus on the following key aspects:

1. Building the core components of the RISC-V EVM.

2. Implementing a RISC-V assembler compatible with blockchain.

3. Optimizing for performance and security constraints.

4. Conducting low-level benchmarking and overall performance analysis.

5. Integrating the customized RISC-V EVM into the Lumoz RaaS environment.

6. Implementing blockchain-specific logic within the RISC-V framework.

7. Conducting performance benchmarking against the standard EVM to analyze register utilization and optimization opportunities.
