Parallel EVM: A New Path to Break Through Blockchain Performance Bottlenecks

The performance of the blockchain network has become a bottleneck for further development in the industry. With the continuous increase in on-chain transaction volume, the industry urgently needs new performance enhancement solutions to meet the requirements of "high performance and low fees." Against this backdrop, parallel blockchains have emerged.

The parallel EVM narrative marks the formation of a competitive landscape in the field of parallel Blockchain, where two strong contenders are vying for dominance. Ethereum's competitors, such as Solana, Aptos, and Sui, all come with parallel processing capabilities, creating a non-EVM parallel camp. In the face of these challenges, the Ethereum ecosystem is also empowering the EVM, resulting in the formation of a parallel EVM camp. Currently, the parallel EVM narrative is in the early stages of development, with broad market prospects.

The parallel EVM projects are mainly divided into monolithic blockchains and modular blockchains. Monolithic blockchains are further divided into L1 and L2. L1 is a new public chain with built-in parallel execution capabilities, while L2 provides scaling capabilities for cross-ecosystem cooperation by integrating the capabilities of other L1 chains.

To understand the technical principles of the parallel EVM, it needs to be broken down into two parts: the virtual machine and parallel execution. The blockchain virtual machine is a type of process virtual machine used for distributed contract execution. Parallel execution leverages the advantages of multi-core processors to execute multiple transactions simultaneously while ensuring that the final state is consistent with that of serial execution.

The parallel execution mechanism is mainly divided into three categories: message passing, shared memory, and strict state access lists. Shared memory is further divided into memory lock models and optimistic parallelization. Regardless of the mechanism, they all increase technical complexity and require practitioners to pay close attention to potential security issues.

Currently, mainstream parallel EVM projects include:

• Sei: Claimed to be the first parallel EVM Blockchain, will adopt optimistic parallelization mechanism in v2 version.
• Monad: Highly favored by capital, introducing superscalar pipelines and optimistic parallel mechanisms
• Canto: Highly decentralized L1 project, will upgrade to parallel EVM
• Fuel: Modular "Ethereum rollup operating system"
• Neon: The first parallel EVM project in the Solana ecosystem
• Eclipse: The fastest Layer 2 protocol compatible with EVM in the Solana ecosystem
• Lumio: An optimistic rollup Layer 2 protocol built in conjunction with Aptos and Ethereum.

These projects provide parallel execution ideas in different ways, sharing technical commonalities while also having their unique achievements. In the future, more L1 and L2 projects will join the parallel EVM competition, further promoting the prosperity of the industry ecosystem.

For Web3 entrepreneurs and investors, the infrastructure optimization brought by parallel EVM will create new business model innovations and investment opportunities. Currently, parallel EVM is in the early stages of development, with multiple projects still in the stage where their value has not been fully realized, making them worthy of ongoing attention.
