1. A method, comprising:
receiving, in a computing system having a memory sub-system connected to a host system, an indication of a storage space request for the host system;
identifying, in response to the indication of the storage space request for the host system, a proof of space application connected to a proof of space plot stored in a portion of a storage capacity of the memory sub-system;
transmitting, to the proof of space application, a first request to cause the proof of space application to disconnect from the proof of space plot in the portion of the storage capacity of the memory sub-system;
receiving, from the proof of space application, a confirmation responsive to the first request;
sending, to the memory sub-system, a second request to cause the memory sub-system to release storage resources occupied by the proof of space plot; and
communicating, after the second request, with the memory sub-system to allocate at least a portion of the storage resources released according to the second request to satisfy the storage space request.
