1000 is THE MOST the block reward will ever be! After block 7000 it will considerably less, dependent on the difficulty.
Regarding the confusion between the conflicting sets of formulae, I think it makes sense to assume that the following is the correct one, otherwise it doesn't really 'ensure a fair launch' ;
Block Rewards: From block 51-250 payout will be 0 to ensure a fair launch
1,000 from block 251-7000
(20,000)(1/√(Difficulty+500)) from block 7001-250,000
(15,000)(1/√(Difficulty+500)) from block 250,001-500,000
(10,000)(1/√(Difficulty+500)) from block 500,001+
This is correct. Sorry, I've been keeping the OP up to date and haven't had a chance to do it on the pool. What's listed on the OP is what is correct, we had to make a few small adjustments to make sure everything runs smoothly. I will go through the last few posts and answer them directly, give me just a few min--lots of things going on so bear with us please. TY
as dev confirmed.
