We are working on a consensus to halve the current block reward from 12500 to 6250. We will add a developers fee of 250 coins. This will make a block reward of 6000 coins and 250 coins for the developers.
We need a developers fund to be used to pay for infrastructure costs, web design, graphic design, marketing, exchanges and more. The developers fund is a very small amount but gives a very large incentive to expand BitcoinZ.
Why do you want to halve block reward now? As I understand halving will take place after block 840000 so why would you like to change that just two months after launch?
If they don't, volume of Btcz will still increase too quickly and mining interest will keep being less and less interesting, so less quantity, better value i think.
