A mining operator entity is configured to implement a given mining instance having a designated amount of storage available for generating proofs of space in a proof of space based mining system. The given mining instance generates a given proof of space in response to a challenge that is computed at least in part from ledger values of a distributed ledger associated with the proof of space based mining system. Utilizing the given mining instance to generate the given proof of space comprises generating the given proof of space based at least in part on a personalized challenge for the given mining instance, the personalized challenge having an associated difficulty determined based at least in part on a comparison of the designated amount of storage available for generating the proofs of space and a maximum amount of storage for a mining instance in the proof of space based mining system.
