#2026年比特币行情展望 $BTC $ETH $BNB Ethereum's Blob Pressure Optimization Scheme (BPO2) upgrade has just been officially launched on the mainnet. According to on-chain data, the target capacity of Blob has now increased to 14 per block, with a maximum of 21—this is a significant improvement.

BPO, as a lightweight upgrade mechanism introduced after the Fusaka upgrade, is somewhat special. It allows for rapid iteration of core parameters related to Blob without the need for large-scale consensus restructuring across the entire network. What does this mean? It means the Ethereum team can more agilely optimize and adjust on-chain data costs.

From a market perspective, the expansion of Blob capacity directly impacts Layer 2 transaction costs. More Blob space = lower transaction fees = improved user experience. This is very helpful for the long-term development of L2 ecosystems like Arbitrum and Optimism. Technically, progress is stable, and the ecosystem gradually benefits.
