What is it anyway
Network stake-dependent interest is the mechanism in which the amount of coins minted during the proof-of-stake phase occurs. Instead of a flat 1% interest, Vericoin's interest rate can range from 0% to just under 3%. The practical range of interest is between 1.5-2.5%. Based upon the number of coins being staked (occurs when the wallet is open and unlocked), the interest rate varies. The more coins staked, the higher the interest rate. This provides incentive for keeping the client open and unlocked, further securing the network. The additional security ensures that the blockchain is not compromised and forked. In addition, it provides incentive for owners of the coin to use it as a savings vehicle as it earns interest at a more reasonable rate and more representative of a real economy. The VeriCoin development team studied the economics of interest/inflation rates in model systems and the key range for a stable economy ranges between 1.5-2.5%. Finally, with a slow inflation rate (1.5-2.5% vs ~10% for Bitcoin), the coins have the potential to become a steadily valued currency.
