I was thinking about Wayback Machine the other day and how safe net could help with this.
As files are made up of immutable data chunks, presumably they could live on long after files associated with them have been deleted. For public files, this made me think - can we store the full history of a file, date stamped and automatically archived?
This would mean that we could have version control built automatically into every file. If you set a date filter, it could mean that the entire network could be referred to in the state maintained at the time - that would be incredibly powerful for historians, never mind being convenient for end users to retrieve old file versions. Obviously incremental file backups would be an easy win too.
Ofc, privacy and security would need to be considered, but public data could automatically behave in this way. Private data could too, if desired.
