The Longest Chain Rule ensures that network will recognise the “chain with most work” as the main chain. The chain with the most work is typically (not always) the longest of the forks. In the figure, the chain split after Block A. Block B and Block B2 seemed to have won the Cryptographic Puzzle at the same time.
How big can a Blockchain get?
