Ephemeral Anchors
Protocol● Common

A proposal allowing zero-value outputs with anyone-can-spend scripts that must be spent in the same package. Enables fee-bumping without pre-allocated anchor values, improving Lightning commitment transaction efficiency.

Technical Notes

Output: OP_TRUE (1 byte scriptPubKey, anyone can spend). Ephemeral: must be spent within the same package, never enters UTXO set. Removes need for 330-sat anchor outputs. Requires v3 transactions and package relay.
