PPCoin does not change anything here. Participants choose a transaction and solve a math problem linking it to the last recorded transaction. We have ppcoined a ppcoined way since the bitcoin of a barter system. To keep Bitcoin secure, the network hash rate must always be much higher than the hash rate that any adversary can put together. Welcome to Reddit, the front page of bitcoin internet.
Revert to standard pricing. That shouldn't have been a video. This is exacerbated by the long term security implications in a pure proof-of-work design. This seems to beat the "proof of work" concept where the stake may be positioned elsewhere. Decentralization is a very vague concept in my mind.
In a neat twist, the bitcoin of solving a puzzle ppcoined confirms the validity of recent transactions made with bitcoins. Cryptocurrencies exist only ppcoined computers. Its basically the same as bitcoin but with deflation instead of a fee because the miner always gets interest. An unusual emergency bitcoin adjustment algorithm causes significant periods of hyperinflation. If there was ever a hard fork to change the fee it would destroy PPC.
The benefit of this cost is that PoS supports the network just as PoW does but with different economic incentives. I will try and make the case for this further on but really I am confident enough in the different design that I believe the currency will make its own case due to a marginal increase in security per transaction cost.
This should sell itself not be sold by people who don't know what they are talking about. In any case the cost of PoS is incredibly tiny in terms of resource usage even though its an attempt to create the same level of financial cost for an attacker without that resource usage because they will have to buy and hold the currency losing money to attack it.
To be accurate PPC does not have a fixed transaction fee in the sense that the fee amount is part of the protocol. It is default client behavior but the size of the fee that is acceptable can be changed by the miners and the amount of fees paid is default client behavior as well. The code for prioritizing transactions is the same as the code for bitcoin.
What is part of the protocol of PPC is that the fees are burned. The purpose of having the fee is to prevent spamming of transactions and not to encourage the miner to make a block since the miner is already encouraged to make a block due to the different inflation model. The motivation to include the transaction is only for 2 reasons: P If the fees get too high they can always be lowered without any protocol change and if the network gets too spammy then fees can be raised.
Its basically the same as bitcoin but with deflation instead of a fee because the miner always gets interest. So it keeps going the way it does now forever instead of changing to be a fee only currency like bitcoin will. Whether that is better or worse is subjective but OP is incredibly false to call bitcoins model unsustainable. I do believe that PoS will result in a currency that has a lower resource cost for its level of security and that this will result in a marginal decrease in the transaction costs of PPC vs bitcoin for a given level of security but PPC is nowhere near that point in its development yet.
For PPC to be secure it still needs a large network of hashing power like bitcoin has and its market cap needs to grow from its tiny just under 4 million dollar amount to something that has some real economic The reason I believe that PPC will be secure at a lower cost is because to attack it you will have to buy it instead of buying mining equipment like you would to attack another crypto-currency and once you are done attacking it you lose!
With an attack using mining equipment the attacker still has mining equipment after the attack but with this they are left with a currency which has been pumped to high prices by the attacker buying up stake meaning the people seeing the attack can actually profit from it as well and dumped to nothing if successful meaning they lose at the original holders gain.
And if it is successfully defended then the main cost of doing that is to simply hold the currency and mint with it not much of a cost at all especially once it becomes more widely distributed as a currency then it could be as a network of high powered mining machines.
There is obviously a lot of unknowns in this model so I am not about to take my speculation and grantee it to anyone but I do support it and believe that a proof of stake currency will prove its value simply by its continued existence. PPC has a faster adjustment to the difficulty meaning an attacker would be losing money by doing this very quickly and while they are attempting to do a PoW attack their blockchain would be littered with PoS blocks from the holders of the currency or it wouldn't be accepted by the network meaning transactions would still be getting through and they would not just have to have more hashing power but also more stake but they can't get more stake by dumping hashing power on the network because the block reward drops: Here are a couple of proper criticisms you can use though: Both of these are set to be removed once the currency is on its feet but they have not been removed yet.
The second is that in order for PoS blocks to be created they must be signed which means the private key must be used putting it at risk when people do PoS. There is a proposed change to the protocol which will remove that risk but it also has not been added yet. PPCoin is still a baby.

Lee says that will make Litecoin less dependent on the activity of a small number of dedicated miners with expensive equipment, allowing a larger pool of miners to compete. That has the effect of decoupling mining and the confirmation of transactions from the cost of electricity and computer power, which King says would be a problem for Bitcoin if it were to become very widely used.
Some Bitcoin devotees worry that alternative currencies could hinder efforts to make the leading cryptocurrency mainstream, but Selgin says that competition could simply increase the odds that any one cryptocurrency succeeds.
