|

/// - 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 whole ecosystem.
