The difference between POW and POS mode

[xzh16888]

The difference between POW and POS mode:

   POW：
       We are familiar with the working mechanism of bitcoin is POW, namely Proof of work, proof of work mechanism.
Proof of work mechanism (POW) is not difficult to understand, in many cases we are using POW. We just didn't understand it.
Without considering the verification condition. (whether central or non verification center.), We can think of anything with a probability of events accumulated are proof of work,  Therefore, POW requires a certain amount of evidence, The proof can be recorded directly can also be based on probabilistic representation, in which the event of small probability cumulative work, The results show that the workload is equivalent to,

POS:

       POS is the "Proof of stake,"  Direct proof that you hold share.In addition to mixed PPC,  The real POS money is no mining process, It is in the block stated ownership certificate, after the shares that can be transferred, not mine. In the real world that is common stock equity, is the most simple. The stock is that used to record the equity, also represents the voting rights and the right to return, In a pure POS system, such as NXT, no mining process,

1 question. if there no mining prcess . who is going to combine the transaction into block?
That's always confusing me about the pure POS concept.

 There is POS and POW like PPC, POS like Communitycoin, and POS forging like NXT. If you hold 1 Million nxt and don't turn on your computer 24/7 you wont get the transaction fees. In POS like Communitycoin, you can just turn your computer on 1x a day and get the reward.  

I prefer the POS like communitycoin.

POS is the future = Coin2 is the future

[over1977v]

POS is more energy effecient, but not the most secure against attack with someone holding a lot of coins.
The future is in POW I think

[jianxinss]

Proof-of-stake is a method of securing a cryptocurrency network through requesting users to show ownership of a certain amount of currency. It is different from proof-of-work systems that run hashing algorithms to validate electronic transactions. It is most commonly used as a supplement to proof-of-work in Peercoin[1] and a few other electronic currencies.

simple！！！！
I say：What's this !!!
POW n POS

[newstone]

POS is the future = Coin2 is the future

and fac,comm,itc......

What is the purpose of this vote?

[zhangcaisbsbn55]

POS is the future = Coin2 is the future

Coin2是未来?

?Probably a dumb question, but is PoS less secure (as in more prone to being successfully attacked) than PoW? How is PoS providing security in the network?
