Ethereum's transaction parallelization plan aims to significantly alleviate network congestion but may not fully resolve it. By processing up to 65% of transactions in parallel using optimistic concurrency control and sharding, Ethereum can boost throughput and reduce latency. Layer-2 solutions like rollups further offload transactions, easing main chain pressure. Proposals like Block-Level Warming and EIP-7928 optimize storage access and enable parallel execution, potentially lowering gas fees and increasing efficiency. However, challenges remain, such as transaction conflicts and the complexity of ensuring security during parallel processing. While these advancements could dramatically improve scalability, peak demand during high-traffic events may still cause delays. A complete solution would likely require ongoing innovations beyond parallelization, such as enhanced sharding or off-chain scaling.
