So at slow start how many zec is each block and is it going to reach 12.5 zec on december 1st?
So zec will start with 12.5 block no 50 or 25?

It increases from 0 to 12.5 linearly over 20,000 blocks so it should take around 34 days (it’ll likely be a bit quicker to to difficulty being low on early blocks)

The amount of ZEC over time is expected to be in line with bitcoin, after the slow start.
Bitcoin began with 50 coins per block. The blocks were mined 10 minutes apart.
ZEC will start with 12.5 coins per block. The blocks will be mined 2.5 minutes apart.
