Good news: Simple Proof has promised me an initial $20k of funding to work on OpenTimestamps.
So far I've partially fixed the scaling issue. I rewrote Riccardo Cassata's Foxglove timestamp request aggregator in modern Rust (the previous version didn't even compile anymore).
https://github.com/opentimestamps/foxglove
Foxglove is now running live on both my Alice and Bob calendars.
This means that I can now scale timestamp _creation_ by throwing servers at the problem. So if someone tries to DoS attack the OpenTimestamps calendars, given enough money to run extra servers, you'll (probably) at least be able to create new time-stamps.
Timestamp _verification_ still has a significant scaling problem that needs to be fixed, and this will be a significantly harder challenge to implement. But I'm making progress at least.
