[size=12pt]Why Peercoin?[/size]
[size=12pt]Peercoin is based on Bitcoin’s revolutionary technology. Like Bitcoin, Peercoin has an anonymous developer or team of developers going by the pseudonym of “Sunny King”. Peercoin was developed in 2012 in response to growing concerns being raised on the Bitcoin forums about its sustainability and long-term health. One of these concerns is how Bitcoin’s distributed network will be maintained. Bitcoin uses what’s called “Proof of Work”. Peercoin introduced the concept of “Proof of Stake” as a long-term replacement for Proof of Work.
The main advantages of Proof of Stake are its extraordinary resistance to centralization…the so-called 51% attack that you may have heard about. In addition, Proof of Stake greatly reduces the energy demands of the distributed network.
Here’s how it works: Each node in the network has but one task – verify transactions. Anyone with a Peercoin wallet can participate. Participants are rewarded based on the number of Peercoins they hold. This is called “minting” and produces a 1% annual return, which is the reward for their Proof of Stake. So little computing power is required to maintain Peercoin’s network that even hardware with minimal capability such as a Raspberry Pi can participate.
There is no longer any reason to pool together computing resources and form alliances, so the threat of a 51% attack essentially vanishes. To gain control of the Peercoin network, an entity would need to acquire 51% of mintable coins. Attempting to purchase the amount of coins necessary to carry out an attack would drive the price up to astronomical levels, making it counter-productive for an attacker because they would be forced to risk their entire investment.
Peercoin uses a hybrid or blend of Bitcoin’s PoW and the PoS systems. Peercoin launched as PoW but has been gradually transitioning to PoS. It will become entirely PoS after a number of years. Why the combined approach? The reason is PoS doesn’t have a fair way of introducing coins into the community user base. It’s critical to prime the system with an initial distribution to get it going. One option is to generate all the coins immediately and sell them to the earliest adopters, but this isn’t very fair. Despite its shortcomings, PoW is very good at jump-starting the system in a fair way.
It is important to state that Peercoin is not intended to be a replacement for Bitcoin or Litecoin. Each currency is good at some things and not-so-good at others. Peercoin was designed to be a store of value. A rough analogy is that Peercoin is a savings account while Bitcoin and Litecoin are more like checking or spending accounts.
Peercoin has a fixed fee of 0.01 PPC per transaction. This amounts to several cents at current exchange rates. It is important to note that the fee is immediately destroyed, which offsets new coin generation due to minting. In this way, Peercoin is neither inflationary or deflationary. It also makes the currency very stable by design and potentially a long-term store of value. Another advantage of the fee is to limit frivolous, micro-sized transactions that can result in an enormous blockchain.[/size]

[size=12pt]Peershares are an inexpensive and decentralized ledger to be used by businesses for tracking share ownership and distributing dividends in an automated fashion. Shares can be transferred and held just like other cryptocurrency units, such as Peercoins or Bitcoins.
Using Peershares, individuals, businesses, or organizations of any size could raise funding through an initial offering without depending on a third party such as a stock exchange. While trading shares through exchanges will be useful to provide liquidity, Peershares can be traded on any number of exchanges just as Peercoins can.
Each business using Peershares will have their own blockchain that is independent of all others. Blockchains can be secured cheaply and easily using Peercoin’s Proof of Stake, once the initial (issuer-controlled) shares has been generated using Proof of Work.
Issuers can distribute dividends as Peercoins, which can then be held by the investors, or if they would prefer, can then take those dividends and convert them to another cryptocurrency or fiat through their preferred exchange.
A share issuer is not vulnerable to the failure of single stock exchange such as BTC Trading or Litecoin Global.
Most importantly, Peershares are accessible by anyone. The template is open-source, and free to download.[/size]
