Block difficulty

Block difficulty in Ethereum runs parallel to the calculation of block difficulty in the Bitcoin blockchain. The difficulty of the block increases if the time between two blocks decreases. This is required to maintain consistent block generation time. The difficulty adjustment algorithm in the Ethereum Homestead release is as follows:

block_diff = parent_diff + parent_diff // 2048 * max(1 - (block_timestamp - parent_timestamp) // 10, -99) + int(2**((block.number // 100000) - 2))

In this algorithm, the difficulty of the block is adjusted based on the block generation time. According to this algorithm, if the time difference between the generation of the parent block and the current block is less than 10 seconds, the difficulty ...
