Ethereum's second BPO hard fork: Blob limit raised to 21, network scalability further upgraded

【ChainNews】Ethereum recently made a big move again—during the second BPO hard fork, the blob size limit was raised from the previous restriction to 21. This change may seem simple, but its actual impact is significant. The blob is a key component for optimizing transaction data on Ethereum, and increasing the limit means that a single block can process more data, leading to higher network throughput. For users, the most immediate benefit is lower Gas fees—transactions become cheaper, and network congestion can be alleviated considerably. This is another step in Ethereum’s ongoing efforts to improve its scalability. In today’s landscape where Layer 2 solutions are becoming increasingly mature, enhancing the mainnet’s efficiency is equally crucial. Although such technical upgrades may not be as eye-catching as price fluctuations, in the long run, they are the foundation that determines how far the ecosystem can go.
