not if anyone can bring up a node

Again, Federated Byzantine Agreement, like Fediverse: anyone can bring up a node (in this case a network validator)

It's up to clients/wallets to pick a selection of validators that are not in collusion with each other.

The real loss in FBA design is trustlessness. That is really what PoW provides.

A bad-faith PoW actor still has to pony up ~50% hashrate. A bad-faith validator just needs to spin up a few validatorss and convince people to configure their wallets to pick more of the bad-actor validator nodes instead of honest nodes.

IMO, it's a small price to pay for the benefit of being (a) super high max. tx/s, and (b) "green", low-carbon-impact crypto

AFAICT the process of registering new nodes could be decentralized or centrally-managed; neither way is specific to the FBA design.

FBA but it seems relatively centralized

Only as much as the Fediverse is. Not all of us run big nodes or even little monero.town

IMO it would not be any different from today. In theory every wallet can be a node. How many people actually run nodes vs just have wallets? The same people that run nodes today, would run FBA validators.

And the network would support 3 orders of magnitude more tx/s, and consume no more electricity than Fedi services.

it's been years now but I remember looking at re-org data and just shuddering

fair

Au contraire. The proteome was solved by LLM transformers trained on genetic strings

Perhaps you are unaware that AI has solved the Proteome. This was expected to be a 100 year project.

Naturally , people die before age 45 and a hell of a lot of women and children do not survive the agony of childbirth

“You cannot regulate the design of a hammer so that it can drive nails but not kill anyone, but you can criminalize the killing of a human by a hammer,” Gawdat said.

God I hate managers who think they're so deep 🙄

I think the majority of the Monero community shares this concern. If there was a better solution for the purposes of securing a decentralized ledger, we'd move on it quickly. Problem is, in all these years, as a community we haven't seen a better system.

PoS tends to continually centralize power. End of story. There is no situation where PoS does not ultimately fully centralize.

Ostensibly super fast mechanisms like Nano are subject to insane re-orgs, which they mitigate by checkpointing the chain, which means the re-orgs that should have happened, don't happen, ... it's a frickin' trainwreck and would be exposed as such under real-world high scale loads.

IMO the next-best solution to PoW is Federated Byzantine Agreement (FBA) aka "validator nodes" like Stellar. These are crazy high throughput, super efficient, and slightly more centralized -- that wallets have to choose a set of validator nodes, and hope that those nodes are not colluding.

Think of FBA Federation as being like the Fediverse: there are semi-centralized hubs. But anyone can spin up a hub and people can migrate easily. It's not 100% decentralized where every node is identical. But you get orders of magnitude more throughput and less electricity use.

It's too early. I read this as "Release the Epstein tapes"
