∂₀ Sepolia Historical Archive

What it does

We decoded 286 million raw Ethereum events from Sepolia's early blocks (genesis through ~3M) into clean, query-ready Parquet files. The focus is on ERC-20/ERC-721 transfers and approvals — the kind of data you'd need for ML training, compliance analysis, or building indexers. Getting historical decoded event data usually means running your own archive node or paying per-RPC-call. We had the infrastructure from another project, so we packaged the output as a flat file.

  I spent 3 years reverse-engineering a 40 yo stock market sim from 1986▲721

  Hello my name is Ben Ward for the past 3 years I have been remastering the financial game Wall Street Raider created by Michael Jenkins originally on DOS in 1986. It has been a rough journey but I finally see the light at the end of the tunnel. I just recently redid the website and thought maybe the full story of how this project came to be would interest you all. Thank you for reading.
