I have been using crypto since 2017, made plenty of dumb trades which caused me to lose out a lot. Currently my portfolio is about 80% BTC and while the new USA admin seems they may do more damage than good to the crypto space I’m still positive about Bitcoin.
This sub seems like a meme or anti-btc sub mostly. Anybody here who isn’t that way?
Sorry but you can’t compare the physical ressources of PoW and PoS, mining isn’t buying a shit tons of ASICs and getting bitcoins.
How it’s recovery model is more flexible ? How does mining can’t adapt to issues ?
51% on Bitcoin has been highly improbable from decades now, miners will see it comming fast enough to adapt. Forks and 51% attacks are two very different concept. You had it with ETH PoW and you’ll probably get new fork even after PoS chains.
Again I never said that PoS was less secure, I said it was more neutral and resilient. Bitcoin needs to be neutral and resilient as a network. PoS is a different consensus mechanism that have different tradeoff.
I mean in general, Bitcoin aside, PoS is more resilient than PoW. The only major resilience issue I know of in PoS is when validators came offline for Ethereum and couldn’t reach finality. But I don’t think that’s a fair comparison to PoW because PoW doesn’t have finality in the first place. Also, because PoS has finality, it’s resistant to long-range attacks, even if someone did a 51% attack (which has never happened for a PoS chain), they wouldn’t be able to rewrite finalized blocks.
Do you understand what it would need to change multiple blocks on 51% attack. Getting 51% of hashrate is a thing, maintaining long enough is another. Also if 51% attacks happen in a PoW consensus it can recover from it, not without any damage but it can recover. On PoS systems, once it happend it’s done.
PoW has probabilistic finality. The deeper a block is buried under subsequent blocks, the less likely it is to be reversed. Deterministic finality is not a universal upgrade — it trades off with flexibility and recovery mechanisms.
Main risks regarding PoS resilience are in my opinion :
Centralized staking: Yes, it’s a concern, but so is centralized mining. We’ve seen real-world 51% attacks on PoW chains due to mining centralization.
Weak subjectivity: True, it’s a real factor, but not a showstopper. Clients just need to use a recent finalized checkpoint.
Slashing risk: It exists in theory, but we haven’t seen it hit honest validators in practice, even on smaller PoS chains.
What chains are you referring too ? Cuz except some SHA-256 mining coins like BCH I can’t remember hearing about that.
Here’s a list of a number of them: https://99bitcoins.com/wiki/51-percent-attack/
I should note that I’m lumping in security as part of resilience, since being able to recover from problems includes being able to recover from attacks and limiting damage from attacks. If something is not as secure it’s not as resilient, either.
