Hi,
i had a questions .. so total Coins: 30,000,000 is the initial supply? and every year it will increase approximately +3.5% ??
Yes the initial supply is 30 M and the network creates 2 coins every minute rewarding a random public key involved in a transaction in the last block, but if there are not transactions in the last block the coins are destroyed. So annual interest is 3.5% only if there are transactions in every block.
"the network creates 2 coins every minute rewarding a random public key involved in a transaction in the last block, but if there are not transactions in the last block the coins are destroyed."
How is the network validating this against an adversary?
An example: miners/stake holders can always include a transaction to itself and change the code so the selection of the pub key is not random, instead rewarding them self with a block reward.
