Few people know, but Bitcoin was actually invented to stop the time war.<p>Huge amounts of human activity go into the blockchain and then the timing of blocks and who finds them is dependent on all of it in a highly non-linear and computationally expensive way.<p>This, of course, makes it infeasible to construct alterations of the past with predictable consequences in the future.<p>As such, its invention was almost inevitable as it's a stable solution that prevents history from constantly changing. :D
