VRC was designed to reduce the PoW phase and enter PoST phase quickly. With a steady block reward and block time of sixty seconds, the PoW phase finished after the first few weeks of launch - 10/05/2014. The PoST interest rate is dynamic and depends on how much the coin is held and staked in the PoST. The dynamic interest rate is pegged at a sensible level of between 0-3% roughly. The PoST interest is gained through transaction fees which are also distributed to the Vericoin fund - to aid in the development and promotion of the currency. There was no premine.
