PoW or PoS? What's best?

[CryptoRama]

PoW is best short-term because it has been shown to work. However it is energy-intensive and not really sustainable indefinitely, so PoS - either pure PoS or else some hybrid or modified system - is the way to go in the long-term.

I think PoW is ok, but the problem is machines are so expensive and you don't get anything from them and also power consumption is very high with bitcoin mining machines than others... Can't they develop better bitcoin machines? Or is bitcoin mined so much now, you can't get anywhere if you don't invest big? Because I think mining bitcoin now is a lot of work...

There are currencyes that uses both PoW and POS, but I think currency should use only one. By my opinion both are great, you don't get anything without work, much better than XRP.

There is no absolute system. PoW has its advantages and disadvantages, just as PoS has. The unfortunate thing is that both cannot be combined in the same project, at least for now so that we can get the advantages synchronized.

Ethereum 2.0 tries to combine the two - there is an interesting article on this that tackles these issues. Let me know if you want a link to it

Casper POS is not removing PoW system but it makes or gives the possibility to the stake holders to get the benefit from the blockchain. That's why the core developer of ethereum has called that as a hybrid system.

This depends on coin price and also how much will cost to get the coin via PoS and how much is the price of coin and if total price is higher than cost to produce is ok, but for some coins is better to have PoS, less cost to produce and if price is ok, a good profit.

In my opinion is this, I know both of these ways are used in order to support the blockchain or to create a coin but I think PoS is much better rather than the PoW since PoW needs a lot of investment and when the coins you're mining are dropping its price you're paying more in your equipment and electricity rather on what you're mining and it consumes a lot of electricity which can be used to do other good things isn't?

While the PoS uses stakes in order to earn through masternode if i'm not mistaken this kind of method is much better rather than the PoW. All of these is just according to my experience and understanding about the PoW and PoS.

I would say both of traditional POW and POS systems have failed.
Though some of the most successful coins like Bitcoin, Ethereum and Monero are purely POW (upto this date), POW are a burden to already limited energy sources in the world. POS on the other hand is a complete failure though some coins have succeeded implementing a different modification of it.

What's your thoughts on Secure Proof of Stake?

[hicies]

Seems like Proof of work is the best to make use of. I don’t really understand this proof of stake you’re talking about, maybe you should just make this in a way it’s easy to understand or just explain further. But in my opinion, I still believe that PoW is the best cause it has proven to be secure.

In my opinion, POW is better than POW because it will reduce power consumption and contribute to protect environment, and it avoids the situation of centralization of big mining coin companies

I believe you meant PoS is better than PoW?

It's right, but POS less decentralized compared to the POS system. The global warming must force us move to the conservative system that called POS.
But it can be manipulated consider how much the power depends on how much your stake holders.

Did you check the Secure proof of stake?
