Dust
Transactions● Common
A UTXO so small that the fee to spend it exceeds its value. Creating dust is discouraged as it bloats the UTXO set. Bitcoin Core defines dust threshold based on output type and min relay feerate. Transactions creating dust outputs may not relay.
Technical Notes
Dust limit ≈ 546 sats for P2PKH at 3 sat/vB relay fee. Lower for SegWit outputs due to smaller spend cost. Ephemeral anchors (v3 transactions) allow 0-value outputs. Dust can consolidate during low-fee periods. Privacy concern: dust sent to addresses for tracking.
