| Min feerate for defining dust. Historically | this has been based on the minRelayTxFee, | however changing the dust limit changes | which transactions are standard and | should be done with care and ideally | rarely. It makes sense to only increase | the dust limit after prior releases | were already not creating outputs below | the new threshold |
