fork generation (IMAGE)

Fork generation. To simplify the dynamics for the models, the authors assume that all miners start mining at t1. At t2, Miner 1 solves the proof-of-work puzzle for block x and starts broadcasting it to the network. By t4, the message has spread to most of the nodes and a new block x + 1 is likely to be appended to block x. However, Miner 2 successfully mines the block at t3, which is later than t2 and earlier than t4. Therefore, based on the definition above, the propagation time is t4 − t2, and the fork is present between time t3 and t4.
