Block finalization

Block finalization is a process that is run by miners to validate the contents of the block and apply rewards. It results in four steps being executed. These steps are described here in detail:

1. Ommers validation: Validate ommers (stale blocks also called uncles). In the case of mining, determine ommers. The validation process of the headers of stale blocks checks whether the header is valid and the relationship of the Uncle with the current block satisfies the maximum depth of six blocks. A block can contain a maximum of two uncles.
2. Transaction validation: Validate transactions. In the case of mining, determine transactions. The process involves checking whether the total gas used in the block is equal to the final gas ...
