A privacy attack where tiny amounts of coins (dust) are sent to many addresses to try to link them when spent.
In a dusting attack, an adversary distributes small UTXOs to many addresses. When the recipient later consolidates or spends those outputs together, the attacker may infer common ownership and link addresses.
A BCH wallet receives dozens of tiny outputs from unknown addresses; marking them "do not spend" helps preserve privacy until they can be consolidated thoughtfully.
Wallet features like coin control, address labeling, and UTXO blacklisting help. Consolidate dust during low-fee periods, and avoid combining coins from unrelated contexts.
Using coin control, a user spends only a single, clean UTXO for a purchase, leaving dust outputs untouched to avoid linking multiple identities.
