Grain (GRA) - P2P Crypto Currency


About Grain (GRA)

Grain is a P2P crypto currency like Bitcoin or Litecoin. It uses PoW/PoS (Proof of Work and Proof of Stake) to mine the coins. It is designed to be the unit of cyber-coin. Grain coin has a total of 50 billion unit to be released, through a fair p2p mining process. It is fast, secure and have sufficient coins for circulation so it can be used in real daily shopping.

Grain is from the family of PPCoin/Novacoin with latest available algorithms that fixed various problems in the PoW/PoS coins. As compared to the PoW only coins, the proof of stake coins are more resilient to 51% attack. Also it is a long term energy-efficient crypto-currency since not all coins are obtained by mining.

Each grain block provides random 1024 - 2048 grains initially. It also provides rare superblocks. The coin uses hash-based algorithm to determine superblocks based on the number of 9s in the previous block hash. It works as follows:

- the hash contains six 9s or less: regular block
- the hash contains seven or eight 9s: 8 times the regular block (about 5% chances)
- the hash contains nine or more 9s: 64 times the regular block (about 1% chances)

Latest version is 1.4: use Downloads menu to download the latest client and source.

* please note, you must upgrade to version 1.5, it is a hard fork.
