Data bomb

A data bomb was a computer program.

Irving Braxiatel planted a data bomb in the Matrix.

Braxiatel planted a data bomb in the Matrix in order to keep the truth about Project: Alpha accessible in case of an emergency. Even though Gallifreyan history was altered afterward so the outcome of the Project happened differently, the data bomb was preserved because the Matrix partly existed outside of linear time.
