Blob-Parameter-Only (BPO) forks

Blob-Parameter-Only (BPO) forks are proposed as a framework for safely and continuously scaling Ethereum blobs, authored by Sam McIngvale, Mark Tyneway and Proto. BPO forks are simple Ethereum forks that change only the blob target and blob limit, aiming to scale in smaller, more regular increments and share the operational burden of hard forks across L1 and L2 teams. The authors propose three conditions for a BPO fork: solo staker minimum bandwidth requirements are agreed upon, the blob increase is provably shown not to increase solo staker reorgs, and blobs are sustainably congested. They cite growing consensus around 50Mbps download and upload for solo stakers not using MEV-boost, and suggest a blob increase is safe if the trailing 30-day p999 block size plus the new blob data fits within that bandwidth.
