Ethereum’s L2 Scalability Under Scrutiny: New Research Suggests Solanas’ Parallel Execution Could Revolutionize Rollups

A new study reveals a critical bottleneck plaguing Ethereum’s Layer 2 (L2) scalability: nearly all current rollups rely on a single-threaded EVM architecture. This design forces all transactions to compete linearly in one global queue, hindering true parallel execution and impacting performance even for applications with high traffic. 🤯 Research highlights that this limitation severely restricts throughput, causing fees to spike during peak demand due to all transactions competing for the same fee market.
