Ethereum has successfully completed the Fusaka upgrade with the BPO-2 fork, significantly enhancing Layer 2 scalability and reducing fees. This upgrade, finalized on December 11, 2024, optimizes data handling for rollups by increasing the target and maximum number of data blobs per block, thereby alleviating congestion and lowering costs for Layer 2 solutions. The Fusaka upgrade proceeded in two phases, with BPO-1 laying the groundwork on December 9, 2024, followed by BPO-2, which enacted the parameter increases. This strategic enhancement is expected to lower transaction fees for users on networks like Arbitrum and Optimism, making decentralized applications more affordable and accessible. The upgrade underscores Ethereum's commitment to scalability and its role as a foundational layer in the web3 ecosystem.
