Mining is the method used to generate DigitalCoins. Miners use the processing power of their GPUs (Graphical Processing Units) or CPUs (Central Processing Units) to secure and process DigitalCoin transactions. Finding a solution to a block rewards the miner who found it so that they have an incentive to process more transactions.
All you need to mine for DigitalCoin is a computer and an Internet connection. AMD GPU's are the most efficient way to generate DigitalCoin currently.
A pool is a collective of miners working together to solve blocks and sharing the rewards. This has the effect of lowering the randomness in mining.
To connect to a pool, use any Scrypt algorithm compatible mining software and point it at a DigitalCoin pool.
