Ok, i made some calculations and it’s possible i’am not aware of some fact or i made a mistake somewhere. But in case my calculation is near to correct there is somehow a problem.

Known values from my last post at the time of writting it:

Blockheight: 589,343

6,926,668 ZEC (transparent amount): sum of all ZEC hold in all transparent adresses due Zecmate.

166,198 ZEC (sprout realtime from gareths node)

204,142 ZEC (sapling realtime from gareths node)

= 7,297,008 this is currently the total amount in circulation than.

Without the slow start mining for the first 34 days the calculation would be 589,343 x 12.5 = 7,366,787.5, but this is not true as there was a slow start, so best ignore this number. Just adding it here for reference as it was mentioned above!!

My next step is to calculate the amount without the slow start. As the slow start was 20,000 Blocks it’s an easy calculation:

589,343 - 20,000 = 569,343 Blocks (this is the number of all blocks with a full Block reward of 12.5 ZEC)

569,343 Blocks x 12.5 ZEC = 7,116,787.5 ZEC (this should be the ZEC amount created by all blocks after the slow start, it’s a fixed number i guess now as well)

Next step, if we substract the known amount in all pools from the known mined amount of 569,343 Blocks we get the following:

7,297,008 (total circulating ZEC)

-7,116,787.5 ZEC (regular mined blocks)

= 180,220.5 ZEC that must have been mined in slow start

Now the hard part to calculate the ZEC rewards for the 20,000 blocks in the slow start, so let’s start with the known facts:

- first block was 0 ZEC and last of the 20.000 blocks was 12.5 ZEC
- I was able to dig out this old post and graphic from 2016:

Over the slow-start period, the

block reward will gradually and **linearly** increase until it reaches the

full 12.5 ZEC at the 20,000th block.

means over the course of ~34 days/20,000 blocks the block reward increased linear from 0 to 12.5 which should result in an estiminate like this:

Day Amount per 24h

01 211.68

02 423.36

03 635.04

04 846.72

05 1,058.4

06 1270.08

07 1,481.76

08 1,693.44

09 1905.12

10 2,116.8

11 2,328.48

12 2,540.16

13 2,751.84

14 2,963.52

15 3,175.2

16 3,386.88

17 3,598.56

18 3,810.24

19 4,021.92

20 4,233.6

21 4,445.28

22 4,656.96

23 4,868.64

24 5,080.32

25 5,292

26 5,503.68

27 5,715.36

28 5,927.04

29 6,138.72

30 6,350.4

31 6,562.08

32 6,773.76

32 6,985.44

33 7,197.12

Total sum: ~125,949.6 ZEC (not 100% accurate but should be pretty close if the above parameters given are correct).

The problem that results here is that due the total circulating amount there should have been mined 180,220.5 ZEC, but the roughly linear calculation comes only to ~126,000 ZEC.

The deficit from the calculation is about: 54,270.9 ZEC.

I tried to make another approach for the slow start mining period and used the 180,220.5 ZEC that must have been mined in this period IF all above is correct and it would result in an average 5,300 ZEC per day, but this no longer would fit in any way into the linear from 0 calculation.

Where did i make a mistake that i come to an estiminated surplus of about 54,270.9 ZEC???

Edit: Adding for reference even there is no need the normal regular block calculation:

12.5 ZEC every 2.5 min.

50 ZEC every 10 min.

300 ZEC = 1h

7,200 ZEC = 24h
