Briefing
Ethereum’s current execution model, relying on sequential transaction processing, creates significant bottlenecks that strain the blockchain’s ability to handle a growing number of decentralized applications and users. This paper proposes a novel solution enabling maximally parallelizable executions within Ethereum through three self-sufficient approaches ∞ strategically predetermining transaction state accesses and incorporating gas-based incentivization mechanisms to enforce a maximally parallelizable network. This foundational breakthrough fundamentally redefines EVM processing, unlocking substantial scalability for future decentralized applications and mitigating existing throughput limitations.

Context
The prevailing theoretical limitation in blockchain architecture, particularly within the Ethereum Virtual Machine (EVM), has been its inherent reliance on sequential transaction processing. This established model, where operations are executed one after another, directly creates significant bottlenecks to scalability, preventing efficient handling of increasing transaction volumes. Existing scalability solutions for Ethereum often inherit these EVM limitations, restricting the extent to which they can truly enhance throughput.

Analysis
The paper introduces a novel conceptual framework to achieve maximal parallelism in Ethereum’s transaction execution. The core mechanism involves two primary components ∞ first, a method to strategically and efficiently predetermine the state accesses of individual transactions. This pre-analysis allows the system to identify independent transactions that can execute concurrently without conflicts, moving beyond the traditional sequential processing. Second, the framework integrates gas-based incentivization mechanisms.
These incentives are designed to align the behavior of network participants, encouraging actions that contribute to a maximally parallelizable network and dynamically enforcing an efficient execution environment. This approach fundamentally differs from previous scalability efforts by addressing the sequential bottleneck directly at the EVM execution layer, rather than solely relying on off-chain solutions or sharding.

Outlook
This research opens significant new avenues for re-architecting blockchain execution environments, moving beyond traditional sequential processing models. Future work will likely focus on the formalization and optimization of state access predetermination algorithms, alongside the refinement of the proposed gas-based incentive structures. In the next three to five years, the practical applications of this theory could unlock dramatically higher transaction throughput for Ethereum and other EVM-compatible chains, thereby enabling the development and widespread adoption of more complex and resource-intensive decentralized applications. This work also sets a precedent for designing next-generation virtual machines with inherent parallel processing capabilities for distributed ledgers.

Verdict
This research offers a foundational shift in blockchain execution models, critically advancing the theoretical understanding of EVM scalability and paving the way for truly parallel decentralized computation.
