Frequently Asked Questions
What is the best CPU for mining Zephyr Protocol?
The best CPU for mining Zephyr Protocol (ZEPH) is AMD EPYC 7702 with 42,093 H/s on RandomX. Net profit: +$0.61/day (gross income $1.14 minus electricity $0.53 at $0.0784/kWh). 29 CPUs compared. Actual profitability depends on your electricity rate, system downtime, and other overhead costs.
What algorithm does Zephyr Protocol use for mining?
Zephyr Protocol uses the RandomX algorithm — memory-hard proof-of-work algorithm optimized for general-purpose CPUs. Uses 2 GiB dataset in DRAM, benefits from large L3 cache and fast dual-channel memory. Used by Monero (XMR), Zephyr (ZEPH), Salvium (SAL) and other Monero forks.. Block time is 120 seconds. Pool fees are typically 1–2% (we use 1% in our calculations). Stale shares are typically 0.3–1% with good connectivity (we use 0.5%). Both factors are accounted for in the profitability table above.
What are the current Zephyr Protocol network parameters?
Zephyr Protocol network difficulty: 3.82 G. Block reward: 3.9923 ZEPH. Price: $0.39. Data is updated every 15 minutes; profitability in the table is averaged over the last 24 hours (96 snapshots).
