99.59% of blob fee bumps kept the same blob
· 6 min read
Blob transactions have an expensive way to say "same data, higher fee." The transaction hash changes, so the network pulls the whole thing again, including blob content it may already have.
EIP-8094 proposes splitting those pieces apart. I checked the premise against 14 complete days of mainnet mempool observations. Out of 3,427 consecutive same-sender, same-nonce blob fee increases, 3,413 kept the exact same versioned-hash array. That is 99.59%.
