Nervos CKB CKB

At 5¢/kWh the most profitable Nervos CKB miner today, the Bitmain Antminer K7 (63.5Th), earns about $5.74 a day and burns $3.70 of electricity, leaving about $2.04 a day. 1 of 13 Eaglesong miners we track are profitable at that price. Set your own power price above and the whole page recalculates.

Ranked by profit per day at 5¢/kWh: Bitmain Antminer K7 (63.5Th) ($2.04/day, 63.5 TH/s at 3,080 W), Goldshell CK-BOX ($0/day, 1.05 TH/s at 215 W), Goldshell CK-BOX 2 ($0/day, 2.1 TH/s at 400 W). The most efficient machine we track is the Bitmain Antminer K7 (63.5Th) at 48.5 J/TH; cheap power favours raw hashrate, expensive power favours efficiency, so the order changes with your price.

At today's price and difficulty the Bitmain Antminer K7 (63.5Th) breaks even at about 7.8¢ per kWh: above that it costs more to run than it earns. Pool fees (usually 1-4%), cooling and any hosting margin come on top, so plan with a buffer. Of the 13 machines we track, 2 are in profit at 3¢/kWh, 1 at 6¢ and 0 at 10¢, which is why miners chase cheap power.

The fastest payback at 5¢/kWh is the Bitmain Antminer K7 (63.5Th): about $1,860 for the machine, $2.04 profit a day, so roughly 2.5 years if price and difficulty stayed where they are today. In practice difficulty usually rises as new machines ship, so real payback is longer; a falling coin price stretches it further, a rally shortens it.

The Bitmain Antminer K7 (63.5Th), at 63.5 TH/s, mines about 3,737 CKB a day today, worth $5.74. That is 0.061% of the network's 103 PH/s. The whole network mints about 6.18 million CKB a day ($9,498), and every miner earns its share of hashrate.

On its own, one Bitmain Antminer K7 (63.5Th) would find a Nervos CKB block about once every 5 hours on average, and luck can stretch that a long way. With blocks this frequent, even a single machine gets regular rewards; pools still smooth the payouts. FPPS and PPS+ pools pay a fixed amount per share (fees often 2-4%), PPLNS pools pay out only when the pool finds a block (often 0-2%, but lumpier).

Right now each block pays about 738.8 CKB including fees, with a block every 10 seconds on average, about 6.18 million CKB a day. About 47.31 billion CKB exist today and there is no hard cap.

Eaglesong is a hash designed for Nervos CKB, which launched in 2019. It is mined with ASICs such as Goldshell's CK series and Bitmain's K7. We track 13 Eaglesong machines; judge them by J/TH (efficiency) against your power price, then by price per TH, cooling type and the warranty and repair options where you will run them.

One megawatt of power runs about 324 Bitmain Antminer K7 (63.5Th) units. At 5¢/kWh that is roughly $20,133 a month in profit before pool fees, cooling overhead and staff, for about $602,640 of machines. That fleet would add about 20% to the network's hashrate, so once difficulty catches up every machine earns roughly that much less. Site profit is very sensitive to the power price: every 1¢/kWh costs about $7,296 a month at one megawatt. CryptoSites.io lists powered land, container farms and hosting with the power price on every listing.

Pick a machine for your power price (see the table above), then sort out power and cooling: most ASICs need 200-277 V at 10-30 A each, hydro models usually 380-415 V three-phase and a cooling loop, and air-cooled units are too loud for a home. Set up a Nervos CKB wallet, point the machine at a pool, and watch temperatures in the first days. If you don't have cheap power and space, hosting is the usual route: a host runs the machine for an all-in price per kWh. CryptoSites.io lists both powered sites and hosting.
