-/// Discussion:
-/// - The admin authority has one lever of power: the ability to adjust the global
-///   mining difficulty. If the difficulty is too easy, miners will find hashes very quickly
-///   and the bottleneck for mining will shift from local compute to Solana bandwidth. In essence,
-///   if the Ore token has value and difficulty is low, mining becomes an incentivized stress
-///   test for the Solana network.
-/// - At the same time, if difficulty is too hard, miners will have to wait a very long period
-///   of time between finding valid hashes. This will bias rewards to well-resourced miners
-///   with large compute operations. Keeping a low difficulty ensures casual miners can
-///   consistently earn rewards and undercuts some of the advantage of larger players.
-/// - Ultimately admin authority should be delegated to a governance mechanism – either
-///   democratic or futarchic – to ensure difficulty is kept at a value that represents the
-///   values and interests of the ecosystem.
