Would be neat to have a single page, client-side website that did the following:

1. Drop a file
2. Connect and sign with Ethereum address
3. Add a "Signed by <address> at <time>" + hash to the top of the each page.

Not venture scale, more signaling that that a crypto signature is the final authority.

Files should be stored on Lighthouse for tamper proof nature

There’s a project called ethsign or something that does this. Have used to sign agreements 

Does this assume that there is an identity that can be associated with the ethereum address? without an identity, it wouldn’t mean much

ens is a good start but needs wider adoption
