What occurs to P2A outputs which might be by no means wanted ultimately as a result of their person did not want a payment bump on their transaction? Do they simply bloat the UTXO set?

Since these outputs require no witness information to be spent, presumably they are going to be swept as soon as the quantity of satoshis within the output is price sweeping. The minimal quantity in satoshis for P2A outputs as of Bitcoin Core 28.0 is 240 satoshis however they can be another bigger worth. This implies if the going feerate for block inclusion drops low sufficient to make a sweep price it, miners are incentivized to brush it.

I had heard that these would carry 0 worth, however the truth is all of them do. Is that this associated to the truth that often (I feel) all outputs want have to be above dust-value for transactions to be propagated? In that case, how is that reconciled with the concept of getting 0-value outputs (or am I simply flawed about that and so they’ve modified to be a minimal of the dust-value?).

At the moment, 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 concept 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 concept is just not sure to a particular output sort, and remains to be being developed for a future Bitcoin Core launch.
