A blockchain funded by data contributors is an interesting idea. If fees for adding data were continually adjusted to keep data size to an economically viable size. I.e. there would be a continual auction of adding data, with the fees spread out among verifiably maintained repositories (say fastest generation of hash across all data from previous hash, every minute.) And each repository could compete by price to service data requests. The point being: long term distributed incentive to maintain and serve data. (Scaling to vast amounts of data vs. sharding - allowing individual repositories to hold partial data - balanced to ensure distributed backups, but not more than necessary to keep each archive size manageable for many providers.) —— Best done without creating any new coin type. I.e. avoid creating any non-aligned hype incentives. Maybe this has already been done?
