Ethereum Fusaka Upgrade: BPO Testing, Client Optimization, and Mainnet Blob Expansion Plan

[Coin World] According to a summary of the 159th Ethereum Consensus Layer Core Developer Conference (ACDC), this meeting mainly discussed: the launch of Fusaka Devnet 2 (testing BPO, gradually adjusting the number of blobs to 20), a performance report from a laboratory on client performance under high Blob conditions (Lighthouse and Prysm clients support 72 blobs/block, Nimbus only reaches 10 blobs, bandwidth and verification load are uneven, requiring optimization to support household stakers), freezing of Fusaka CL specifications (merging four key PRs, Devnet 3 to launch within two weeks, execution layer specifications to be finalized at the next ACD meeting), BPO strategy and timeline (aggressive testing of 20-48 blobs on Testnet, conservative incremental increase on Mainnet from 9→18→24, BPO1 preset in Fusaka client, BPO2 pending Mainnet data evaluation, dropping coordination costs), Glamsterdam fork proposal (EIP-7782: shortening slot time from 12 seconds to 6 seconds; PR 3510: laying the foundation for flexible slot time), etc.
