Proof of Work (POW)vs Proof of Stake (POS)

[hugeblack]

I agree that users don't really see that downside of POW, however, it's still there, and, in the long run, is a pretty big deal In my opinion.

Are you just making small baseless posts like this to increase the activity to up your rank?

Today you have made a total of 21 posts, and most of the posts are very small and baseless.

account may try to get one of those Active Badges, although I think that such reasons will lead to more - karma or even banning the account from posting.

Everybody's choice, really But from what I got on this thread, is that POW - safety and stability (in exchange for computing power), POS - more for speed and possibilities (for less energy), but more centralized and thus, - not preferable to some.

If you refer to confirmation time or transaction per seconds when saying "speed", then PoW or PoS doesn't really matter. What matters are block time (how often new block should be created) and maximum size of the block.

In the world of blockchain, consensus mechanism are the backbone of decentralize network, ensuring security, scalability, and efficiency. These two of the most prominent mechanism, the Proof of Stake and Proof of work has spark serious arguments on the community
Now, I need your thoughts because I believe that the Proof of work lead on high security, this is because it requires immense computational power reducing the risk of 51% attack.

You’ve probably heard a lot about 51% attacks, and honestly, it’s pretty clear that BTC is not likely to fall victim to one. A single person just can’t own 50% of the hash rate needed to mine and process transactions all on their own. Even quantum computers are not a threat here, thanks to the spread of nodes across different regions.

These nodes are controlled by various entities, and while individual nodes join larger ones to pool their computational power, it’s still incredibly unlikely that any single node or group could ever control 51% of the hash power. So, practically speaking, pulling off such an attack is pretty much out of the question.

After all the arguments and debates, I think that both PoW and PoS will both be playing in the world of the blockchain technology and cryptocurrency for years to come. What is good in here is that we have choices and we are not limited to only one. As we know both do have pros and cons and it all depends on what side you think can be serving a platform well into the future. Overall, this can be between two things: security and efficiency though they themselves are also debatable, in the first place. PoW is more secure and PoS is more efficient though this notion can be changing right now.

Now to get to your question - Proof of Stake allow a bunch of nasty attacks on the validators who select transactions, which usually can be bribed to include transactions into the next block, but they can also go one step further and subvert the transaction's address completely and replace it with another that sends the proceeds to them.

None of this is possible in Proof of Work without access to the private key.
