Dust Limit
The smallest transaction output amount a network's nodes will typically relay.
The dust limit is the smallest transaction output value that a network's nodes will typically accept and relay, since a smaller amount could cost more in future fees to eventually spend than the amount itself is worth.
Amounts below this threshold are generally called "dust," and transactions attempting to create such an output are typically rejected by network nodes.
Examples
- An attempted transaction output below the dust limit is typically rejected by network nodes.
- Dusting attacks deliberately send amounts near the dust limit to many addresses.
