The blockchain landscape is constantly evolving to overcome limitations and unlock new possibilities. One of the latest innovations to address scalability within the Ethereum ecosystem is Parallelized Ethereum Virtual Machines (PEVMs).

Read on to learn about parallelized EVMs and the potential impact of parallelization on Ethereum’s scalability.

What Are Parallelized EVMs? 

To understand parallelized EVMs, let’s first grasp the Ethereum Virtual Machine (EVM).

The EVM allows for the execution of smart contracts on the Ethereum Network. It provides the infrastructure vital to all transactions happening on the blockchain. The growing adoption of Ether and other Ethereum-based tokens strains the EVM, leading to calls for its scaling.

One intervention that’s gaining traction is parallelized EVMs.

Parallelized Ethereum Virtual Machines (PEVMs) enhance blockchain scalability and efficiency by allowing multiple transactions to be executed simultaneously rather than sequentially.

Imagine them as supercharged versions of their predecessor capable of handling multiple transactions together. This approach is crucial in tackling the blockchain trilemma as it significantly reduces latency, boosting transaction throughput.

Some of the front runners in the PEVM adoption are the Sei network, Neon, and Monad. The Sei Network went live in August 2023, attracting roughly 29,000 active users. Neon is also active and working on integrating Ethereum decentralized applications (dApps) into the Solana ecosystem. Meanwhile, Monard is yet to launch despite being production-ready.

How Do Parallelized EVMs Work? 

PEVMs leverage the power of parallel processing to achieve timely and scalable transactions.

Unlike the typical EVMs that handle transactions back-to-back, PEVMs split transactions into smaller, independent tasks that can be tackled simultaneously. This means setting up different points for the concurrent handling of multiple trades.

There are many approaches to parallel processing, but two popular ones stand out:

  • Sharding: Imagine dividing the Ethereum blockchain into smaller, self-contained shards, each with its own EVM. Transactions are then distributed across these shards, allowing for independent and simultaneous processing.
  • Rollups: These batch transactions off the main Ethereum chain, processing them on a separate layer, and then re-submitting them to the mainnet for verification. This significantly reduces the burden on the main Ethereum network, leading to faster and cheaper transactions.

The Potential Impact of Parallelized EVMs on Ethereum

PEVMs can significantly reduce transaction times and fees by removing network bottlenecks, making Ethereum more user-friendly and accessible to developers and users alike.

With PEVMs paving the way for faster and cheaper transactions, Ethereum can potentially handle a much larger volume of activity. This opens the door to widespread adoption of dApps and DeFi, bringing the power of blockchain to a broader audience.

The increased processing power of PEVMs could unleash a wave of more complex and resource-intensive dApps, pushing the boundaries of what’s possible on Ethereum. Applications that might have previously been impractical on the blockchain could become feasible. 

Additionally, making improvements on Ethereum’s mainnet could significantly impact other Ethereum layers. L2 scaling solutions could gain more attention, leading to further development and adoption among users. 

PEVMs, however, also present a possible downside. The technical complexity required to implement parallelized EVMs might lead to centralization if only a few big players can implement it. They could also present backward compatibility and transition challenges to existing smart contracts. 

Benefits and Drawbacks of Parallelized EVMs 

PEVMs could hold so much promise for crypto enthusiasts. But like any technology, it could have its drawbacks too. 


  • Reduced transaction latency: Devolving transaction handling to many units hastens their confirmation. Users will no longer have to endure lengthy completion times due to network clogging.
  • Lower transaction fees: PEVMs streamline transactions, eliminating the need to pay more for prioritized exchanges, which makes transaction fees more affordable. 
  • Enhanced Interoperability: PEVM projects such as Neon are working on bringing Ethereum dApps to Solana. Such initiatives will make it easy for users to interact with their peers on different networks without migrating to their platforms.


  • Increased complexity: Implementing and maintaining robust PEVMs can be technically demanding. As such, developers and users may face a steep learning curve.
  • Potential security risks: Parallel processing introduces new synchronization and coordination challenges, increasing the likelihood of bugs and errors with improper implementation

Final Word

Parallelized EVMs are the latest attempt at achieving Ethereum scalability. By introducing parallel processing capabilities, PEVMs open the doors to various applications, from real-time financial transactions to seamless cross-chain exchanges. However, these novel projects require meticulous development and rigorous security edits to ensure stability.
