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.

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

Yes ... And it's spawned even more innovation. Right now the L2s are building momentum!

Huh, very nice! I'll see if the price of gas changed, thanks!

They should really be using renewables by now /s

You should also check out current L1s. Most stablecoin transactions aren’t happening on an Eth L2 - see “Total Transaction Size by Blockchain, Last 30 Days”

PoS is a superior mechanism design than PoW from the fact that miners acting in bad faith in PoS have their stake burned so they can't keep on acting bad. While to mess with PoW miners only need to guarantee temporarily excess hash power - look up "Bitcoin Cash: 51% Attack" for examples.

Like everything in tech, the devil is in the details, algorithm details in this case, so far it seems to be working out just fine.

PoS at best makes a different tradeoff, it's certainly not strictly superior.

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.

lol what this nonsense. tether's regarded as the safest bc their biz model is providing entities usdt for usd without offering interest on the cash.

now why would any entities want to deposit usd into a private bank and receive usdt without any yield on their cash? you think you understand tether so well maybe think about it for a few minutes
