Saving Data to the DWeb
summary
Environmental Data & Governance Initiative archives vulnerable government data by storing files as 256 KB chunks hashed into a Merkle DAG so each folder gets a single content address. IPFS is used for static archival copies and Dat for mutable feeds, files served by their hash or read key and nodes automatically rehost chunks so popular files gain redundancy. A Deer Park air quality dataset is preserved both on the Internet Archive and on IPFS to reduce single‑point failure risk.
