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 38,146 H/s on RandomX. Net profit: +$0.36/day (gross income $0.85 minus electricity $0.49 at $0.0727/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: 4.62 G. Block reward: 4.3377 ZEPH. Price: $0.32. Data is updated every 15 minutes; profitability in the table is averaged over the last 24 hours (96 snapshots).
