Proof -of- Work Blocks 401 (0.2%)
What is it?
I understand they mined the first 1b NuShares. You can see that when you check the blocks. Mining is deprecated now, in case you think you can mine a few more
Yes, there’s the genesis block and then 400 PoW blocks that generated the initial shares.
Ah OK.
Now while I am at it, how come
getinfo
in the wallet console returns a non-integer number 1007908816.6508 of money supply ? Since tx fee and POS rewards are all integers, there seems no way to create or destroy a fraction of a NSR. Did the initial generation of share generate fractional shares?
A transaction can include any fee as long as it complies with the minimum fee. So someone can destroy a fractional amount of shares by adding extra fees. That may be what happened.
Did my importing nubits private key into S-wallet change the money supply? I still have that unspendable 5.002 NSR in the wallet.
No, the money supply is only updated when a block is accepted.
