I always believe that POS is much better than POW. Energy saving, safer...
But "Fake Satoshi" Dr Craig seems to believe that POW is better than POS when he said: POW is fair & for everybody who work hard while POS is for people who are wealthy (they have much money for staking).

What do you think?

Of course POS is much better than POW. Forget the Fake Satoshi guy, friend.
POW is a waste of energy of our world. POS is not
In POW consensus, the owners of the coin and hash power may be different.

I think that POS is better. POW have many risks such as equipment failure, electricity fees, etc.

No one can really answer you this because so far both ways have flaws and aint really a perfect solution.With pow network depends from minners that most of the times aint loyal and will point their gear towards more profitable coin.On the other hand pos leads to centralisation where most of masternodes/coins belong to only few individuals...

POW is a previous version but POS is on demand. POS is a mining technology that is replacing the POW technology. Proof of stake has some advantages over proof of work. POS will save the people from having spamming messages from the hackers and so it is on demand now.

No doubt, POS is better than POW. POW is a previous version but now POS is on demand. Proof of stake is a mining technology that is replacing the POW technology. Proof of stake has some advantages over proof of work. POS will save the people from having spamming messages from the hackers and so it is on demand now.

Pos is the truly decentralized system but it looks like asic miners were destroying anything. POS will become a useless system in the future. POS is the future. Remember this bitcoin gold has been getting 51% attack the blockchain has been exploited and the scammer steals the bitcoin gold. POW waste a lot of energy.

But what he said is true, to maximize profit when staking, you must have more coins to get higher mining reward.
PoW have huge electricity cost too. I think PoS would not exist if PoW was the best method for mining.
Either it PoW or PoS, they have the advantages and disadvantages each others.

As mentioned above POW is energy hungry and POS on the other hand have improved a lot over time and now can replace POW with same level of security.
As of decentralization, at current time, POS can be more decentralized than POW as mining are mostly done by industry grade miners.

actually i see for the cost will be the same only, but because the power efficiency used POS is better. But POS also does not guarantee if transaction speed can be better than POW. between POS and POW has advantages and disadvantages of each.

POS in crypto-currency mining is much better and will gradually be introduced into all crypto-currencies. This type of mining is much more economical and environmentally friendly.

As far as i now POS is better than POW. Because POS is less risky and their technology also good than POS. That’s why peoples are more connect with POW.

Environmental wise, PoW will cause the use of huge electricity into nothing more than confirming transaction while PoS will seems to save up the electricity because it doesn't need to power up bunch of mining tools, If im to choose, I'd choose PoS, it's better to have an environmental friendly cryptocurrency than the ones that making global warming even worst

Power of stake is always better. In Pow, there is a wastage of energy and the rate of failure is more. Besides, Pow has many risks with it.

I'm not sure which is better. But I prefer POS rather than POW. I do not have the ability to participate in POW so I want to try POS.

- POW is asking a service user to prove that they have made a donation (usually the cost of doing the math) to prevent network attacks such as spam and theft. Dedicated Dedicated Service (DDoS).
In relation to Bitcoin, POW means evidence of bitcoin digger's contribution to virtual money exploitation.
- PoS is another way to validate transactions and gain distribution consensus.
PoS is still an algorithm and has a general purpose with PoW, but the implementation process is quite different. PoS is emerging the first time on the bitcointalk forum back in 2011, the first digital currency. Using this method is Peercoin in 2012, along with ShadowCash, NXT, BlackCoin, NuShares / NuBits, Qora and Nav Coin.
* POS surpasses POW at several points:
- Energy saving.
- A more secure network because of the cost to pay to attack becomes more expensive: if a hacker wants to buy 51% of the total coin, the market responds by raising the price quickly.

I think both POW and POW have their own advantages.
However, I am more optimistic about POS, because the POS mechanism does not consume a lot of resources.

What? POW is fair for everybody? Not at all you have to also buy expensive mining equipment and pay a lot for electricity so it is not also only for wealthy people?
And what about current Bitmain 42% dominance? It is not a problem?

POS is good on its own part while POW is also cool with it own use, but POS is more of zoning the reward to some people and leaving major user aside while POW also require alot of equipment to make it work with financial aspect which also same like POS, so the only difference between them is time and energy require for POW while POS only require your money to stake and get your reward ,so with this reason POS is better to POW.

I agree with you because in both have shortcomings and advantages.
how we judge it.
sometimes humans can only judge without knowing the struggle of it

i hate to agree with the scammer Craig Wrigt but i feel the same way about POW and POS. POW is so much fairer and more secure when it comes to processing transactions and distributing the supply.
with a POS system one person only has to be rich to do nothing and get paid a lot of money and attacking that system can be much easier by someone who gets in early and has a lot of stake.
with POW you still have to do a lot of work and even if you get in early (like having a lot of bitcoin now) you still have to buy ASICs spend money and use electricity to attack the network and fail. and that is much harder than POS.

I think POS is better the POW, but he's correct in saying that POS is for the wealthy. The more you have staked the bigger % of the POS you will be taking. In saying that, if you're wealthy you can build big mining farms and take a bigger % of the POW  as well.

I would not say you do not have a point which you do. However, discarding the opinion of the satoshi guy is not also right since what he said is not far from the truth. The only thing though is that, with the POW thing, even the richer dudes also still stand a better chance than those who do not have much since it would take a lot to set up a mining rig anyway and that would give the miner the chance to keep having more while energy goes for it.

POS is more like a version of investing and holding while getting from it based on the percentage of your stake and I really see nothing bad with that.

I like to invest in the coins which are having POS feature as it will enable me to earn extra while I will be holding those coins for better prices. People are holding bitcoin for $20k but it has no mechanism of getting interest for the amount of coins being hoarded. I love POS and now I look for setting up masternodes. I guess in future we will get something new which will more profitable then mining and POS systems.

Better than all - POI)) Seriously, it seems to me that POW will be a thing of the past. We are all here for green technologies and reducing the consumption of resources of the planet? Yes, there may be those who in POW will deny it for a long time, but here tendencies have long left for big players who control the market.

I encourage more POS because:

- PoW can't be used on small and weak devices such as smartphones. These devices not only lack the space to store hundreds of gigabytes of blockchain data but they also do not have enough computing power to dig effectively. Phone battery will run out very fast but not really accomplish anything.
- PoW is very slow. With Bitcoin, every 10 minutes a block, and only transactions in that block are processed. Everything else must wait for the next block. The consequences are long waiting times or expensive transaction fees (higher transaction costs are processed faster).
- PoW is consuming a huge amount of electricity. Only one single block has consumed more electricity than the demand of some countries for a whole year. This will only get worse. The dependence of pre-coding on electricity is unsustainable in most stable environments. This dependency also means that higher electricity bills or government-imposed limits on types of electricity can "kill" an entirely digital currency.

I chose POS because it is more efficient, low power consumption, and good for holders, in some cases POWs / Miners sell their coins and make prices go down or dump

You cannot really deny the fact that what he has said is simply the truth because that is what POS would always do as it ends up giving chance to the holders of the token to get more in the long run without having to work for it. But, POW has proven security measurements whereas POS is claiming about secured when more people are staking but not yet proven in real time against 51% attack kind of threats.

Moreover, it is understandable however that those who are mining today have some bucks to dish out, so if you can actually get to invest in something you believe in and hold while getting something huge from it gradually, is not a bad thing. It still balls down to the same thing.

The two are good but it depends on individual. for those who can get cheap electricity and are able to set up a mining rig, POW is better for them but for those who don't have such generosity of energy and funds for a mining rig, I think POS is better as they will keep getting dividends on their staked coins without having to do anything else.

POW will always be better because there is actual proof of work which can be done by anyone interested enough to do so.  Proof of work is essential to decentralization.  POS is the epitome of centralization.  No matter what the premine, POS will always create a situation where users have to go to one exchange or another to PURCHASE COINS.  This basic difference between POS and POW is undeniable.

All the 'save the planet' arguments are TOTALLY irrelevant because it dismisses the idea of doing POW efficiently and with little or ZERO impact to the planet.  This is VERY possible and the benefits of POW should not be thrown out because of short-sighted concerns that can easily be corrected.  

POS creates a situation where early adopters benefit disproportionately.  at least with POW people can join later and still benefit as efficiencies typically scale with the mining time.  POS is simply this:  Trust me, buy me, profit.  It is completely assanine.

The only future for POS models is with Masternodes as part of an POW model.  

I'm sure POS will live on and also be successful but going forward, I don't see many new POS model implementations being successful.

Yes, Satoshi himself stated the disadvantages of both which is pretty obvious. The idea of decentralization comes with POW coming into play and for the main fact and like you said, POS just simply give room totally for centralization and as far as I am concerned, that sucks. We could as well just stick with bank monopolies in that case.

Nevertheless, the same way they both have their advantages, they also have their disadvantages, so one way or the other, I actually go with your saying that it is actually difficult to answer. Bother are better for a coin developer but for an investor point of view, I must say POS is highly preferable one. Yes, why not we make some free coins while we are holding up. I guess earning interest here sounds like our basic right for our contribution. Investors of POS must have thoughts about that.

Of course I think that POS is more interesting for ordinary people.  Although if I chose, I would choose not POS and not POW. In my opinion, there are more profitable and interesting algorithms for people.

I initially thought that pow is the real thing and pos is just like holding and earning interest but as i learned more i realised that pos is not interest, this model is also actively participating in network solutions like pow and that too without the use of equipment and electricity, so pos system is not interest based it is also active system and you are getting the reward to work for the network it is not interest simply.

POS is good choice.
POW is very risk.

I think proof of stake is much better than proof of work but some project are now making use of the two to leverage on more technologies

I think the two have advantages and disadvantages and this is the reason some new projects are combining the two

I prefer POS over POW. As day by day mining is becoming less profitable with an increase in the difficulty of mining. In a recent case, there is news of Reducing ETH mining block reward to 2 ETH from 3 ETH. See if someone is wealthy he can have his mining farms and can mine. same goes for POS more staking more profit.

Proof-of-stake has some limitations that make it more centralized than proof-of-work, but proof-of-work does result in a blockchain that is more resistant to tampering. I personally think that blockchain that implement a hybrid system are likely to be more successful, such as 50/50 POW/POS as these will have the benefits of both worlds whilst cutting down on the energy burden keeping the network running. Win/win.

We should understand that every consensus algorithm has its pros and cons. Ideal algorithm haven't been invented yet.
P.s
I prefer pos, despite all.

I don't trust both of them but I can't avoid it at all so I use POW here. I suppose it is more reliabel and stable one which doesn't bring so much losses for example.

This topic seems to reappear here with a surprising regularity, but I'm still curious why you would believe or trust someone whom you yourself call a "Fake Satoshi"? With that said, I can't gather how you can honestly consider POW more fair and available to everybody while POS being only for people who are wealthy. Care to explain? Have you checked the prices for bitcoin miners recently? If anything, it is POW which is for those who are extremely wealthy and highly specialized in this field, which is very demanding in terms of technical expertise.

On the other hand, POS is exactly for everyone in the context you mean it as you don't need to have a hefty startup capital to join the club of coin miners. Apart from that, it doesn't require profound knowledge of the gory details associated with the technical aspects of mining.

What am I missing?

For me, proof of stake is better than proof of work. Need less electricity, faster, fairer and needn't for high performance hardware.

PoW is far too energy intensive to be a long term solution. The central argument against PoS as an alternative has been that it is less decentralised than PoW. The idea being that the only thing preventing someone from control over 50% of the nodes and completely controlling the currency is money. But if you look at mining the same argument can be made that it is possible to lease over 50% of the hashing power or buy up enough of the available ASIC mining rigs and also gain control if you throw enough money at it. If a PoS system is implemented that makes it very easy for everyone who holds the currency to take part in the process and would require you to own over 50% of the currency before you could exert effective control over the network then it would be much more impervious to anyone successfully doing that since the price of miners and hashing power tend to be more inelastic to supply and demand than the price of coins. Gaining control over half the mining power may be possible but if you tried to control over half the Ethereum or Bitcoin you would end up driving up the price so that all the fiat in existance would probably not be enough money to buy control.    

PoW consumes lots of energy and this is killing the ecosystem and the environment and I think that those that are using PoS are much much better, high efficiency and more usable.
For those that use PoW it is good because you are converting "energy" into the money and those who make the most profit are those who may steal the power energy from the gov.

I prefer the work of Proof of Stake because it saves electricity more than Proof of Work, but either POS or POW has no effect on whales because they can become rich with both proofs, with POW they can buy a lot of mining tools while with POS they can buy lots of coins, it's the same.

I think at this point in time, POW is also only available to rich people. After all, to mining cryptocurrency with POW you need to buy very expensive equipment. But, with POS mining does not need to buy and maintain equipment.

Proof of of stake is better than proof of work.  The proof of stake use less energy and less energy is good for the envinroment!  Proof of stake will ensure that a lots of people become a node and many masternode will emerge and thus decentralisation of cryptocurrency is achieved!

masternodes are the exact definition of centralization! it is basically a "bank" that is processing transactions and in some of the master node coins you can't even run one without spending and risking a huge amount of money.

as for PoS, it has the worst way of distributing coins. basically anyone with money receives new coins. and it means there will be a lot of rich guys who are receiving a lot of free money which they don't hesitate to dump. that is why POS coins are declining.
in POW at least the miner does some actual work and gets paid for that work and then if they sell they are selling to cover their  costs and pay their bills and also take profit not just receiving free money to dump.

POS still better than POW. POS require less energy and material. everyone can become a node with minimum set up. while POW require dedicated high end mining machine and heavy electricity to work. cost over production is way lesser for POS compare POW.

POW implies the costs of purchasing mining equipment, which means speculation in the market of video cards and coins tied to them. On the other hand, POS can be good only when investing directly in 1 coin, which means its direct growth in capitalization. I believe that POS is the best economic solution.

That's debatable.

Maybe POW is a good reward for those people who are working hard but its really costing a lot of energy where activitsts are against to it. They are using this mechanism to say that crypto's aren't good for the world. POS is really rewarding for those that believed to that coin and managed to have plenty of it.

IMO, we need balance and both of them are good.

In my opinion so far, nothing better than POW has been invented. All the same, POS is money from the money and nothing more, but time will show in which direction technologies will go.

I don't think this is not a real argument. If we focused on what this argument is about conceptually and tried to create a currency that wouldn't have that "flaw" (I don't think it is really a flaw), then we would have to impose some external rules (like POW does), but they would still be susceptible to breaking by someone with enough resources, money, or power. To put it differently, we can't escape this vicious circle of "backdoors". And here we come to the conclusion that it may be impossible to create an algorithmic currency as opposed to currencies based on physical limitations like scarcity of gold or some other physical phenomena which are beyond the reach of human influence and control (like gravity or time).

Besides that, it seems natural that if someone holds more than 50% of all coins he can force his will on the remaining minority of users (in terms of coins held). Then again, if we wanted to create a currency resistant to this kind of influence or attack vector, it may not be possible to "create" it in the sense cryptocurrencies are created. We would have to employ some external factor which would be completely out of our control. Gold is a close enough approximation to that but it is too "rigid" for a currency to be used in the modern economy.

POS is better here, it is more preferable for its features and speed of increasing popularity which plays not the leats role in the case of current cryptomarket.
