Hi, I have a stupid question, for sure I'm missing something,

Finalization Block: It is an ordinary bitcoin block with some exceptions
- 1- Its merkle root points to a Net Merkle Tree
- 2- It is fixed to yield a hash that is as difficult as target difficulty * 0.02
- 3- It has a new field which is a pointer to (the hash of) a non empty Shared Coinbase Transaction
- 4- The Shared CoinBase Transaction's sum of difficulty scores is greater than or equal to 0.95

I cannot see any reward for finalization block.
where is the incentive to to mine a finalization block?

Block reward is distributed by means of Shared Coinbase Transaction in which the first transaction is supposed to be a special transaction fixed to have a score of 0.02 and obviously will refer to the wallet address of the miner (of Finalized Block).

Coinbase Share: it is new too and is composed of
- 1- A Collaborating miner's wallet address
- 2- A nonce
- 3- A computed difficulty score using the hash of
  - previous block's hash padded with
  - current block's merkle root, padded with
  - Collaborating miner's address padded with the nonce field
- 4- A reward amount field
Shared Coinbase Transaction: It is a list of Coinbase Shares
- First share's difficulty score field is fixed to be 2%
- For each share difficulty score is at least as good as 0.0001
- Sum of reward amount fields is equal to block reward and for each share is calculated proportional to its difficulty score
