If you look at the Crave block explorer, you will see that in every block, 10 new Crave are minted - 6 of which go to those running masternodes, and the other 4 to those staking.
So why the website say there is an 11 Crave block reward?
In addition to the 10 Crave minted every block, there is also 1 Crave that is temporarily 'set aside', so to speak. These funds are reserved for budgeting and governance purposes.
Since the block spacing is 60 seconds (one block is added to the blockchain every minute), there are 1440 blocks per day, and 43200 blocks per month. This means that every 30 days, 43200 Crave are 'set aside' for governance.
Can you explain this governance?
Anyone is able to submit proposals to further the growth and development of Crave. If the community likes the idea behind a proposal, masternode holders can vote to have it passed. On the contrary, they can also reject the proposal.
One part of the proposal is a one-time / monthly payment amount. This introduces a bit of competition among those submitting proposals - since everyone is fighting for a portion of the 43200 monthly reserved Crave.
How are these 'reserved' funds allocated?
Every 30 days (43200 blocks), we have this thing called a superblock. The point of the superblock is to reward the addresses that are associated with accepted proposals. It is not until this superblock in which the reserved funds are actually minted and added to the circulating supply.
Say that during a certain month, 6 proposals are accepted, and will take 40000 of the 43200 possible budget funds. The extra 3200 Crave do not go to any Crave wallet or developer address - they are never created.
To summarize - if the accepted proposals were to take 100% of the reserved funds, it would be the equivalent to having an 11 Crave block reward in terms of supply emission. However, if no proposals were accepted and 0% of this reserve were allocated, it would likewise be the equivalent of having a 10 Crave block reward.
