Orphan Rate
۱۴۰۵/۱/۲۷
Orphan rate is the percentage of valid blocks found by a miner or pool that become orphan blocks — i.e., are not included in the main chain and yield no reward.
Formula
Orphan rate = (orphaned blocks / total blocks found) × 100%
A pool finding 100 blocks per day with 2 orphaned has a 2% orphan rate.
What affects orphan rate
- Latency — the main factor. High latency between miners and the pool server means blocks are broadcast slowly, increasing the chance another miner's block wins
- Pool size — larger pools find blocks more frequently; if internal communication is slow, orphan rate rises
- Network propagation — how fast a newly found block reaches the rest of the network
- Block time — coins with shorter block times have inherently higher orphan rates (more frequent simultaneous finds)
Orphan rate and pool selection
When choosing a mining pool, a lower orphan rate means more of your found blocks actually pay out. Pools typically display their orphan rate in statistics dashboards.
