Zetacoin

Zetacoin is an open source cryptocurrency based on the Bitcoin protocol, it uses cryptography to control the creation and transfer of the digital currency. It is a SHA-256 based cryptocurrency which provides a much quicker transactions speed and a quick difficulty adjustment.
Specifications
Zetacoin is not premined and is based on the latest Bitcoin 0.8.99 source with a block target of 30 seconds (20x faster then Bitcoin).
Difficulty retargets every 4 blocks based on last 90 blocks (Quick difficulty readjustment).
The block reward is 1000 ZET, halving every 80640 blocks (about 1 month) and will not drop below 1 ZET (inflationary).
The total coin supply is 160 million ZET + small yearly inflation (about 1 Million).
160 million coins will be mined in around first year, which are already in circulation at this moment. Thereafter around 1 million per year (inflationary).
This small inflation is a better incentive to keep the network hashing than purely transaction fees (for coins with a solid maximum of coins, like Bitcoin.
General Usage
With multiple large and innovative projects running into getting this coin broadly accepted for real life transactions, the usage of Zetacoin lies in the daily done expenses.
Visiting a restaurant, a clothing store, at the supermarkt, basically the usual city-like stores and merchants. The main goal focuses on real-life (micro)transactions in combination with a Costumer/Client-friendly, quick and ease of use environment!
Transactions
Transactions with Zetacoin are more or less identical to Bitcoin transactions. When a Zetacoin user makes a purchase, the payment triggers a broadcast of the financial transaction to the Zetacoin network. The Zetacoin transaction is a digitally signed message transferring the ownership of zetacoins from one Zetacoin address to another. For the transaction to take effect it must be recorded in a public ledger or public transaction database called the block chain. Approximately every thirty seconds a bundle of transactions, called a "block", is added to the block chain. The incentive for this accounting process is known as mining, explorering a block, rewards the miner with a certain amount of zetacoins. Transactions fees are optional and generally lower than those of creditcards or any other money transfers.
Wallets
Zetacoin functions using public-key cryptography just like Bitcoin, in which a user generates a pair of cryptographic keys. A public one and one private. The public key is the Zetacoin address to send other Zetacoins to. The private key allows full access to the Zetacoin wallet. So in terms only the private key can decode information encrypted with the public key; therefore the wallet owner can distribute the public key openly without fear that anyone will be able to use it to gain access to the encrypted information, but should NEVER distribute the private key. The Zetacoin addresses are public key hashes, containing 34 numbers and letters which start with the letter Z.
