What occurs to P2A outputs which are by no means wanted ultimately as a result of their person did not want a payment bump on their transaction? Do they only bloat the UTXO set?
Since these outputs require no witness knowledge to be spent, presumably they are going to be swept as soon as the quantity of satoshis within the output is value sweeping. The minimal quantity in satoshis for P2A outputs as of Bitcoin Core 28.0 is 240 satoshis however they will also be every other bigger worth. This implies if the going feerate for block inclusion drops low sufficient to make a sweep value it, miners are incentivized to brush it.
I had heard that these would carry 0 worth, however actually all of them do. Is that this associated to the truth that often (I believe) all outputs want have to be above dust-value for transactions to be propagated? If that’s the case, how is that reconciled with the thought of getting 0-value outputs (or am I simply fallacious about that they usually’ve modified to be a minimal of the dust-value?).
At present, all non-OP_RETURN outputs have a non-0 satoshi worth mud restrict that is calculated based mostly on the script measurement and another heuristics.
The unique thought for “Ephemeral Anchors” was cut up into two separate ideas: Pay To Anchor(P2A) which is the script format, and “Ephemeral Mud”, which is the power to have a mud output with out unduly bloating the utxo set.
The latter thought is just not sure to a selected output sort, and remains to be being developed for a future Bitcoin Core launch.
