I setup a fundraiser on Geyser for tx fees for the OpenTimestamps calendars. One of them recently ran out entirely, and the other is close to running out. They cost about 100,000sats/week, $40/week, to run at the moment for a transaction every ~28 hours, so I'm hoping the community can chip in.
I do have funding for the server costs. Just need funds for the tx fees.

Imagine going to all this trouble to make a random beacon service, and relying entirely on a single private key rather than using Bitcoin block hashes.
...and yes, they got their terminology wrong: this isn't a timestamp, it's a random beacon. They're proving that something was recorded _after_ a point in time. Not before.
I got my testnet seed working again BTW.
I accidentally shut it down a few months ago when I shut down a server without realizing that the testnet seed was running on it... It's now running on the same server as my mainnet seed, and that server is only used for seeds.
