This is essentially how bitcoin's proof of work algorithm works. They maintain the difficulty by adding 0s as computers get faster.

Yep. So much compute and energy thrown away because proof of stake wasn't figured out sooner.

Bitcoin still refuses to move to proof of stake. It's obscene https://digiconomist.net/bitcoin-energy-consumption

Earlier quoted context omitted.

You need some proof of work to prime the pump for proof of stake. Otherwise, you have no security because there's nothing at stake. Now that we have plenty of proof of work completed, we don't really need any more. You can bootstrap your new coin by burning Bitcoins as a provable value sink to get it started on the path to POS.

You could stake fiat in a bank account I guess?

That's pretty much Tether. You could probably bootstrap a POS coin by staking Tether. There would be a lot of details in getting it to eventually grow independent of Tether. I don't claim to know how that could happen. Especially since Tether is not a highly-regarded/trusted token in the community.

Ah this brings back fond memories of the EngineYard challenge that consumed HackerNews in 2009[1][2][3][4].

From what I recall it was a bunch of YC founders writing janky cuda code vs djb who proceeded to smoke us all.

Got a 404 but the title was a nice throwback, $2k in cloud credits too!

Did Ethereum end up moving to PoS? How did that work out?

Might as well ask, as tangentially (even so slightly) related: DAE know of a way to get/generate "vanity" (arbitrary or close) Bitcoin addresses?

Same way as vanity onion domains: brute force. Anything else would be a security flaw. If you're asking how to actually get one yourself, just search for "bitcoin vanity address" on github. There are plenty of projects to choose from.
