Blocknative is open to collaborating with anyone working on this RFP to illuminate core infrastructure issues including potential censorship. We have a comprehensive historical dataset of mempool data on Ethereum which we consider a public good. In aggregate, the database consists of >5 billion unique, detailed transaction events (over 14.6 TB of compressed data) growing by more than 150 million events each month.
If you are working on this RFP and interested in the dataset, feel free to reach out to us in this thread or on our discord in the #general channel.
