In the dynamic landscape of blockchain technology, the pursuit of scalability remains a paramount challenge. Recent developments in parallelizing the Ethereum Virtual Machine (EVM) have sparked significant interest among developers as they explore solutions to enhance transaction throughput. However, the implementation of parallel EVMs is a complex endeavor, involving multiple strategies and addressing various technical challenges.

Parallel EVMs Landscape: A Brief Overview

The necessity of parallel EVM stems from its ability to revolutionize the efficiency of traditional EVMs, which process transactions sequentially. By enabling multiple operations to be executed simultaneously, parallel EVMs significantly improve the throughput and performance of the network.

Implementation methods of parallel EVMs include scheduling-based concurrent processing, multi-threaded EVM instances, system-level sharding, and face challenges such as unreliable timestamps, blockchain determinism, and technical challenges such as verifier income orientation.

Monad Labs, with its Layer 1 project Monad, aims to enhance scalability and transaction speed through unique technical features, including processing up to 10,000 transactions per second, a one-second block time, parallel execution capabilities, and the MonadBFT consensus mechanism.

Sei V2, a crucial upgrade of the Sei network, aspires to be the first fully parallelized EVM. It offers backward compatibility with EVM smart contracts, optimistic parallelization, and introduces the new SeiDB data structure for increased transaction processing speed and network scalability.

Neon EVM, operating on Solana, seeks to provide an efficient, secure, and decentralized environment for Ethereum dApps. It enables developers to deploy and run dApps seamlessly, leveraging Solana’s high throughput and low cost.

Lumio, a Layer 2 solution by Pontem Network, addresses Ethereum’s scalability challenges by supporting both EVM and Move VM. It aims to bridge the gap between Web3 and Web2 experiences.

Eclipse, an Ethereum Layer 2 solution, utilizes SVM to accelerate transaction processing. With a modular rollup architecture, it integrates Ethereum settlement, SVM smart contracts, Celestia data availability, and RISC Zero fraud proof.

Various blockchain platforms, including Solana, demonstrate different implementations and advantages of parallel technology. Solana uses Sealevel technology for parallel smart contract processing, showcasing the diverse approaches to achieving scalability.

Key Challenges in Adopting Parallel EVMs

The adoption of parallelism in EVMs presents challenges such as resolving data races and read-write conflicts, ensuring technology compatibility with existing standards, adapting to new ecosystem interaction patterns, and managing increased system complexity. Security and resource allocation become crucial factors that require careful consideration.

Understanding the Basics of Parallel EVM

The Ethereum Virtual Machine (EVM) serves as the core computing engine of the Ethereum blockchain, executing smart contracts by processing bytecode. Transactions, integral to the EVM, play a pivotal role in functionality, causing messages to be called or contracts to be created.

The necessity of parallel EVMs arises from its ability to significantly improve blockchain network performance. Traditional sequential transaction processing consumes considerable energy, placing a burden on validators. Parallel EVMs revolutionizes consensus by allowing multiple operations to be executed simultaneously, leading to enhanced network throughput and scalability.

Parallel EVMs Necessity: Revolutionizing Blockchain Efficiency

• Sequential EVM processing consumes excess energy and strains network validators, hindering widespread blockchain adoption.
• Parallel EVM allows simultaneous execution, boosting network throughput, solving congestion issues, and enhancing overall performance.

Impact on Blockchain Technology:

• Energy-Efficient Transaction Processing: Offloading validator workload fosters a sustainable blockchain ecosystem.
• Lower Transaction Fees: Improved scalability and increased throughput make blockchain platforms economically attractive.
• Smoother dApp Operations: Processing transactions simultaneously ensures smooth operations during network peaks.

Implementation Methods of Parallel EVMs

• Sload and sstore operations in the EVM architecture serve as entry points for conflict-free parallel/concurrent execution.
• Three common forms of parallel/concurrent EVM implementation include multiple threads of one EVM instance, multiple threads for multiple instances on one node, and multi-threading across multiple nodes (system-level sharding).

Distinguishing Features in Blockchain vs. Database Systems:

• Challenges: Unreliable timestamps, ensuring transaction consistency, and aligning validator goals with system-level consensus.
• Requirements: System-level consensus, faster execution for higher returns, and advanced scheduling algorithms considering block constraints.

Shaping the Future of Blockchain Parallel EVM’s transformative impact on blockchain technology highlights its potential to address scalability challenges. While implementing parallelism poses technical and ecosystem challenges, the benefits, including improved throughput and lower latency, position it as a key driver for the next generation of blockchain networks.

Implementation Methods of Parallel EVM

In the current EVM architecture, sophisticated read and write operations like sload and sstore present opportunities for implementing parallel/concurrent EVM. Different forms of parallel/concurrent EVM include multiple threads of one EVM instance, multiple threads for multiple EVM instances on one node, and multi-threading of multiple EVM instances on multiple nodes (system-level sharding).

Technical challenges include data race issues, read and write conflicts, and ensuring compatibility with existing EVM standards and smart contract code. Ecosystem adaptability and increased system complexity are additional considerations for developers, users, and service providers.

Future Outlook

Parallel EVMs holds immense potential in improving blockchain scalability and efficiency, marking a significant shift in technology. Successful implementation requires overcoming technical challenges, ensuring compatibility with existing ecosystems, and fostering broad adoption.

Developers play a crucial role in designing smart contracts and data structures that support parallel processing. The compatibility of parallel EVMs with the Ethereum ecosystem ensures a smooth transition, allowing existing dApps to integrate seamlessly.

As a key step in addressing fundamental limitations of blockchain scalability, parallel EVMs are poised to shape the future of Web3 infrastructure. While challenges exist, the potential benefits, including higher throughput and lower latency, position parallel EVMs as a cornerstone for the next generation of blockchain networks.
