In a centralized system a central server routes calls and can make mistakes.
In a decentralized system like BitMesasge the likelihood of a misroute is so low that it would take a trillion trillion universes a trillion trillion lifetimes before the chance of it happening once was even remotely likely, given every atom in each universe were sending a message to an other atom each pico-second.
What do you mean by this? And how would this prevent a similar bug in the future?
