Because our brain implants link us to the Kernel, a plethora of information is being collected about us. Advanced systems frequently employ genetic and informational methods of management. It is common practice among collectors throughout The System to gather memories from the remains of the dead.
In this rusty world, it may be possible to preserve humanity by archiving these memories. In the year 2145, the "Blockchain" was the only method of data storage that ancient humans were aware of.
