Blocknative Data Archive

Blocknative logs all mempool transactions from nodes in multiple geographical regions for the Ethereum mainnet blockchain. This includes information on when transactions entered, exited, replaced, finalized, or were rejected. Currently there are two datasets:

  • Mempool Archive which contains the history of Ethereum mempool transactions since November 2019.

  • Blob Archive which allows you to enter a blob hash to receive the full blob data or the blob summary of any blob that has entered the Ethereum mempool.

The Data Archive is available for public benefit to enable researchers and community good projects. It may be freely used for non-commercial purposes. If you want to use this data for commercial use, contact us at Terms and Conditions - License CC BY-NC-SA 4.0
