In order to follow the intended chain after the unvoted testnet3 hard fork, we implement checkpointing and require a block from the fork to be present in the main chain. This is performed by rollbacking the main chain at startup if an invalid checkpoint is detected, and refusing to extend the main chain unless a checkpoint rule is satisfied. We use checkpoints to push wallet onto the intended unvoted chain due to it having significantly less total work than the chain being reorged.
