I found this idea of creating an nsec from multiple nsecs insteresting in that it may provide another element of doubt. If an entity can create an sp address from a quorum of nsecs then the next spend out to a fresh address could be owned by any of the underlying nsecs adding multiplying affects of possible interpretations. View quoted note → My main focus is on how to further obscure the sent utxo from the sender since anyone can now send a dust utxo to any nsec.
