Can someone explain to me what DPOS is?

As the title says, can someone explain to me what Dynamic POS is?

Thanks

ROFL... You started a discussion about PoS, which has a lot of posts and now I'm not sure if your goal is really to receive explanations about how DPoS is working.

LOL!
true, I want to know what the difference is between them.

There is POS, POS 2.0, DPOS and DPOS 2.0.

Why so many?
What is the difference?

Which is better?

Here is detailed article about DPOS.

Nice one!

Thanks bro

DPOS seems to refer to completely two different things.

Firstly, there is BitShares' DPOS system which stands for "delegated proof of stake". This is the most common meaning of "DPOS" and is the one that most people probably think of and are referring to:

http://wiki.bitshares.org/index.php/DPOS_or_Delegated_Proof_of_Stake

Then there is also something called "dynamic POS" which OP mentioned. Dynamic proof of stake (also called DPOS) seems to be a variant of proof of stake used by the lesser known altcoins Positron and Isotope. I'm not sure how it differs from traditional POS but it looks like it involves stake rewards which change over time depending on which blocks are mined:

Interesting.

How many kinds of POS are there?

I just saw a coin in the altcoins mentioning vPOS...

Try researching bitcointalk or make some searches on Google. Sometimes you can't explain something with simple post and there are detailed documents about how different PoS is working.

Peercoin uses minting (which uses coin age), NXT uses transparent forging (where the next forger is known in advance), BitShares uses delegated proof of stake (DPoS) where 101 delegates are elected to process transactions, Reddcoin uses proof of stake velocity (POSV), and NEM uses proof of importance (POI) where factors other than just the size of your balance alone are also taken into account when determining staking probability.

There are probably others that I have missed but I think these are the major ones.

Also forgot to mention that they were pretty much developed in that order too, with Peercoin being the first PoS coin and NEM being the newest (well technically, PoI more of an off-shoot of PoS rather than pure PoS and had already been in development for months when it was launched but you get the idea).

The basic idea behind PoS is actually quite simple. Each coin is like a minature mining machine that solves blocks just like the way a real miner does. The more coins you have, the more blocks you can generate and the more coins you can get. Most of the above are simply variations of this basic theme.

OK, I think I am starting to get it now.

One more question.
I see Pure POS on many coins yet, they have 1-4000 blocks POW.
How can it be pure POS if it has POW in the beginning?

That sounds similar to the system that Blackcoin uses.

If I remember correctly, those initial blocks are mined via proof of work in the same way Bitcoin is mined today. However, after a while, the coin disables PoW mining entirely and switches over to proof of stake. Hence there are two separate phases: a pure PoW phase and a pure PoS phase.

The PoW phase is there to distribute the coin. The problem of how to distribute a PoS coin is a tough one. Another option is to distribute them via an IPO where all of the coins that will ever exist are pre-generated all at once and sold in a massive auction. This method is popular but also somewhat controversial. Indeed this is the system that NXT, Qora, and a few other notable PoS coins have used.

So NXT and Qora have no annual interest and they have no POS block rewards?

The block rewards come from transaction fees in the network. Transactions are put into blocks which contain fees. Whoever forges that block gets the fees. The total number of coins in the entire network remains constant.

Which means no inflation...
