The multi-layered design enables support for multiple blockchains and makes for a more stable and scalable environment for miners.
Yes, Nervos (CKB) can be mined and is one of the few seriously mineable layer-1 coins that have consistently stuck with proof of work. It is mined via the Eaglesong algorithm using specialized ASIC miners such as the Antminer K7, which provide computing power around the clock and in return receive new CKB as a block reward.
The Nervos peculiarity: the minted CKB is not only a means of payment but also reserves storage space on the blockchain (Common Knowledge Base). How mining works in detail, what hardware you need and what matters when it comes to pool and wallet is covered by the following questions as well as our Nervos miner overview.
Nervos (CKB) is the base layer (layer 1) of the Nervos network and serves as a storage and security layer; the abbreviation CKB stands for "Common Knowledge Base", and holding CKB tokens reserves storage space on the blockchain. Technically, Nervos uses the so-called cell model, a generalization of the UTXO model known from Bitcoin, and secures itself via the proof-of-work algorithm Eaglesong.
For miners, Nervos is particularly interesting because, unlike many former mining coins, it has not switched to proof of stake but continues to be mined classically via computing power with ASIC hardware such as the Antminer K7. What the network is actually used for is covered by the question on the use case further below.
Nervos pays out the mining reward in two stages: from a primary emission that decreases over time and a fixed secondary emission. Eaglesong ASICs such as the Antminer K7 produce a new block roughly every eight seconds on average.
The procedure is proof of work like Bitcoin, only Nervos computes with its own purpose-built algorithm Eaglesong. Whoever finds a valid block receives the block reward in CKB; because a single device only rarely gets its turn at this difficulty, almost all miners pool their power in a pool such as ViaBTC or F2Pool. Mining thus brings new CKB into circulation and secures the network against manipulation.
Nervos mining is based on the algorithm Eaglesong - a proof-of-work computational task developed specifically for Nervos, built on a Keccak-style sponge construction and deliberately kept simple and easy to analyze. Eaglesong is the cryptographic task that every Nervos ASIC is hard-wired for.
Eaglesong is today completely dominated by specialized ASIC devices such as the Antminer K7; graphics cards or PCs have no chance. Other coins partly use entirely different algorithms (Bitcoin for example SHA-256, Kadena Blake2S), which is why their hardware is not suitable for Nervos and vice versa. Anyone who wants to mine CKB needs Eaglesong hardware specifically.
For Nervos mining you need Eaglesong ASIC miners - devices whose chips are built exclusively for the Nervos algorithm and therefore deliver many times the computing power per watt compared to graphics cards. The reference device is the Antminer K7 from Bitmain with around 58 TH/s at about 2.8 to 3 kW; besides that there are smaller, older iBeLink models for CKB.
ASIC stands for application-specific integrated circuit: such a device only handles Eaglesong, but it does so particularly efficiently (the K7 sits at around 0.049 J/GH). CKB can no longer be mined economically with GPUs or CPUs today. You will find the currently available models in our Nervos miner category.
With the Eaglesong algorithm of Nervos (CKB), not only graphics cards but also FPGAs are out of the race - economically, CKB can practically only be mined with specialized ASICs such as the Antminer K7.
A K7 reaches around 58 TH/s and thus a hashrate that a GPU does not come close to at the current network difficulty; per share found, a graphics card also consumes many times the electricity. For Nervos there is therefore practically no way around the ASIC. You can get the Nervos ASIC from us - whether running it is worthwhile depends on electricity price, CKB rate and difficulty and can be estimated up to date with a mining calculator.
Anyone mining Nervos (CKB) via an Eaglesong ASIC such as the Antminer K7 needs no additional mining software - everything necessary is in the device firmware. Setup is done in the browser via the K7's web interface: select a CKB pool such as ViaBTC or F2Pool, enter the Nervos wallet address, and the miner goes into operation.
Optionally, with several K7s, management software can be connected for central control and monitoring. For a single device this is not necessary; the factory firmware is sufficient.
You can buy specialized Eaglesong ASICs - in the industrial segment above all the Antminer K7 from Bitmain (around 58 TH/s, approx. 2.8 to 3 kW) as the common reference device, besides smaller iBeLink models for CKB. Important when buying: make sure the device is really built for Eaglesong, because similarly named iBeLink models (such as the BM-K1) are intended for other algorithms like Kadena. You will find the currently available models at the top of this page.
At Cryptohall24 you order the right Nervos miners directly - new or as a tested used device. Which model suits you depends on whether you want to mine at home or have it hosted and how high your budget is; we are happy to advise you on that.
Anyone who wants to get into Nervos (CKB) cheaply will find smaller or used iBeLink devices in the lower price segment; at the upper end stands the current industrial ASIC Antminer K7 with around 58 TH/s. Hashrate and efficiency (J/GH) determine where a device lands within this range.
With Nervos the margin is often slimmer than with larger coins, which is why the ratio of purchase price, electricity costs and CKB yield should be calculated particularly precisely - a cheap entry via an older device can make more sense here than the most expensive new generation. The up-to-date model prices are at the top of this page.
For Nervos the Antminer K7 is the benchmark - and used, it delivers its around 58 TH/s on Eaglesong just as reliably as new, usually at a clearly lower price. Tested used K7s are a fixed part of the range at Cryptohall24.
With older iBeLink models a second look is worthwhile: they still mine Nervos, but need more electricity per unit of power (higher J/GH value) and are thus more sensitive to the electricity price. Whether used pays off is decided by the combination of purchase price, efficiency and your electricity costs. Take a look at our Nervos miners - we are happy to calculate your specific case.
Mining Nervos (CKB) means generating coins yourself with an Eaglesong ASIC such as the Antminer K7 and continuously receiving block rewards. Buying Nervos means acquiring ready-made CKB immediately at the current rate via a crypto exchange such as Bitget or Binance, provided CKB is available there.
Buying is the fast, rate-dependent entry without technology. Mining is the ongoing generation, whose profitability depends on electricity price, CKB rate and difficulty - with Nervos additionally on the availability of the K7, which as a specialized Eaglesong miner is not available everywhere on the market. Cryptohall24 sells the Antminer K7 and offers hosting; the CKB trading itself is handled by the exchanges.
Nervos miners are in practice exclusively air-cooled. The Antminer K7 as a typical Eaglesong device for CKB releases its waste heat via powerful built-in fans; a Hydro variant built specifically for Nervos - unlike with the large Bitcoin lines - practically does not exist on the market.
This reduces the question to the environment: the K7 needs sufficient fresh air and a location where the warm exhaust air can escape. Since these devices are audibly loud under load, many operators prefer to have their K7 hosted in a data center rather than running it in living spaces.
A Nervos miner is loud - an air-cooled Antminer K7 reaches around 75 decibels in operation, roughly the level of a running vacuum cleaner, because its high-speed fans have to dissipate the waste heat of nearly 3 kW in continuous operation. As a continuous noise over 24 hours, this is hardly bearable in an ordinary living space.
Since Nervos mining is dominated by such Eaglesong industrial devices, there are hardly any quiet alternatives for the living area. A practical solution is a separate, well-ventilated room such as a basement, garage or utility room. Anyone who wants to avoid the noise completely has the device hosted in a data center, where the volume does not matter; soundproofing boxes lower the level but change nothing about the heat and electricity issue.
Yes - the mined CKB needs a Nervos wallet as a destination, whose receiving address you enter in the mining pool. The official solution is the Neuron wallet of the Nervos Foundation; besides that, lighter alternatives such as JoyID, imToken or SafePal are widespread.
Behind each of these wallets is a private key that belongs exclusively to you - and thus the CKB too. For larger holdings, a hardware wallet such as Ledger complements the setup by supporting Nervos (CKB) and storing the keys offline particularly securely.
Nervos (CKB) is mined via the Eaglesong algorithm in several pools; common ones are ViaBTC, F2Pool, 2Miners, Binance Pool and woolypooly. The differences lie mainly in fee, payout model and minimum payout.
With ViaBTC there is a direct cooperation that brings discounted pool fees via our link. Practical tip for CKB: enter two to three pools in the Antminer K7 so the device automatically switches over in case of a connection drop - check the current conditions directly with the pool beforehand.
For Nervos (CKB) there is no pool that would be the best for everyone - the sensible one is the pool whose fee, payout model, minimum payout and size suit your Eaglesong hashrate. With low power, a larger pool noticeably smooths out the payouts.
A good starting address is ViaBTC, with which we cooperate and through whose link you receive discounted fees; besides that, F2Pool and 2Miners are widespread. A tip from practice: choose two pools with a similar fee and enter both so your Antminer K7 automatically falls back in case of outages.
With Nervos you can mine solo - the high total Eaglesong hashrate of the CKB network, however, means that a single Antminer K7 only very rarely finds a block itself.
A hit would bring you the full block reward, but realistically long stretches with no yield at all line up before that. For this reason, almost all Nervos miners pool their power in an Eaglesong pool such as ViaBTC or F2Pool, which combines the finds of all participants and turns them into regular payouts. Solo only becomes a real option once you operate a very large amount of your own K7 hashrate.
An air-cooled Eaglesong ASIC such as the Antminer K7 draws around 2.8 to 3 kilowatts around the clock when mining Nervos, which in continuous operation amounts to roughly 25,000 kWh per year; older Eaglesong models are below that depending on hashrate, but are noticeably less efficient. Electricity is thus by far the largest ongoing cost factor.
How high the consumption exactly turns out is decided by the efficiency in J/GH: the K7 reaches around 0.049 J/GH, the currently best value among the Eaglesong ASICs. The electricity price is therefore the most important profitability lever - at household electricity around 30 ct/kWh, continuous operation becomes expensive, which is why mining is often done at locations with cheap energy.
A Nervos miner such as the Antminer K7 draws around 2,800 to 3,000 watts, considerably more than an ordinary household appliance, and therefore mandatorily requires a 220-240-volt connection - a 110-volt socket is not sufficient.
In Germany this is practically unproblematic, since household sockets supply 230 volts anyway; but make sure the circuit is adequately fused, because nearly 3 kW of continuous load places considerable strain on a normal line. With several K7s, a suitable power distribution and a dedicated, correctly dimensioned circuit are recommended. These details can easily be clarified in advance for your location.
Yes, Nervos (CKB) has a halving every four years, similar to Bitcoin: the base reward from the so-called primary emission halves each time. The first halving took place in November 2023; the primary emission runs with a total maximum of 33.6 billion CKB until around the year 2103.
A peculiarity of Nervos is the additional secondary emission of a fixed 1.344 billion CKB per year, which is paid out among others to miners and supports the reward in the long term. For miners this means: with each halving the primary reward per block does decrease, but the secondary emission cushions this decline - all the more do electricity price and CKB rate decide on profitability.
Nervos has a two-stage emission model. From the primary emission, a maximum of 33.6 billion CKB are created via mining, whose issuance decreases every four years through a halving and ends around 2103. In addition, there is a secondary emission of a fixed 1.344 billion CKB per year, which continues without time limit.
Unlike Bitcoin, due to the ongoing secondary emission there is therefore no hard, final upper limit on the total quantity. For miners this is relevant because the secondary emission is deliberately designed to support the miner reward over time when the primary emission declines through the halvings.
Whether Nervos mining is worth it in 2026 depends above all on the CKB rate, the network difficulty and your electricity price. Nervos is technically fully mineable, but the margin with CKB tends to be borderline - with ordinary household electricity, an Antminer K7 is, depending on market conditions, sometimes only just in the black or even in the red, because the electricity costs reach the yield.
Nervos mining becomes viable above all with cheap electricity or at a hosting location with a low energy tariff, as well as with a rising CKB rate. The secondary emission has a supporting effect, securing part of the miner reward. You can most reliably run through your scenario in advance with a current mining calculator such as AsicMinerValue.
With the Antminer K7 you mine CKB via the Eaglesong algorithm, measured in GH/s. Your earnings are the mined CKB quantity times the rate, minus electricity costs and pool fee - the margin with Nervos, however, is often slimmer than with larger coins, because the CKB rate and block value are comparatively low.
The calculation therefore reacts sensitively to the electricity price: even a moderate increase can turn the net yield of the K7 negative. Difficulty and CKB rate change daily, so there is no fixed figure. Check your setup with an up-to-date mining calculator for the K7.
How many CKB add up per day depends on the ratio of your Eaglesong hashrate to the network difficulty and your pool share - an Antminer K7 delivers around 58 TH/s for that. There is no fixed daily amount, because the block reward draws from base and secondary emission and the difficulty continuously readjusts.
Together with a fluctuating CKB rate, the daily yield therefore shifts continuously. Estimate the expected gross yield with your hardware using a current mining calculator and subtract your electricity costs for the net value.
Whether a Nervos miner pays its way, you estimate with a mining calculator based on the device's key data. For an Antminer K7 you enter about 58 TH/s on the Eaglesong algorithm at around 2.8 to 3 kW; together with your electricity price, the tool calculates the estimated daily or monthly yield from the current CKB rate and network difficulty.
The up-to-date Eaglesong values are listed at AsicMinerValue. Because rate and difficulty shift continuously, the result is only a snapshot - check your scenario again shortly before purchase.
The electricity price is the all-decisive factor in Nervos mining at home. The Antminer K7 (Eaglesong, nearly 3 kW) runs continuously, and household electricity around 30 ct/kWh is mostly too expensive for that - especially since the CKB margin is slim anyway. Home operation is technically possible, but economically only under favorable electricity conditions.
With a cheap tariff or surplus solar power from a photovoltaic system, which would otherwise only go to the grid for a few cents, the calculation tips toward worthwhile. On top of that comes the practical side: the K7 is loud and produces noticeable waste heat, so it belongs in a basement or garage. With several devices, hosting in a data center is usually the more economical solution.
As a side effect of mining, a Nervos miner produces a lot of usable heat: an Antminer K7 with nearly 3 kW converts the absorbed energy practically entirely into heat while mining CKB via Eaglesong. With it you can, for example, heat a workshop or garage or preheat intake air.
Important for context: a single K7 is a supplement, not a properly sized heating system. And at around 75 decibels, the device needs a quieter location such as a basement or workshop anyway. Whether heating operation is worthwhile is decided by the electricity price - with cheap electricity or your own photovoltaics, the energy used does not just heat, but the CKB yields recover part of the electricity costs.
Nervos (CKB) is the base layer of a network that has in recent years moved strongly toward Bitcoin layer 2. Via the RGB++ protocol, Bitcoin UTXOs are linked with the CKB cells, making programmable assets and smart contracts possible for the Bitcoin ecosystem; at the beginning of 2025, the Fiber Network additionally added a Lightning-compatible payment network.
For miners, what is mainly relevant is that this active ecosystem keeps the network alive. The mining hardware secures precisely this base layer via the Eaglesong proof of work - mining is therefore not an end in itself, but supports the applications that build on Nervos.
Cryptohall24 takes the Nervos ASIC Antminer K7 (Eaglesong) directly into hosting: you buy the device, we set it up in the data center, supply it with cheap electricity and operate it 24/7 - you continue to decide on pool and wallet yourself.
With Nervos this makes doubly good sense, because the CKB margin is slim anyway: a K7 with around 75 decibels of noise and noticeable waste heat quickly eats up any advantage at home, while a predictable industrial electricity price carries the calculation. What you should look out for when choosing a host we summarize in the mining hosting guide.
The hosting device for Nervos is the Antminer K7 from Bitmain: the Eaglesong industrial ASIC delivers around 58 TH/s at about 2.8 to 3 kW and dominates CKB mining - a continuous-load machine that Cryptohall24 accepts for 24/7 data center operation.
Smaller, very economical niche ASICs such as the lower iBeLink models or compact devices for the living area generally remain excluded; they are designed for home operation, and we are happy to sell and explain those. Whether your specific Nervos device fits into hosting we are happy to clarify on a case-by-case basis.
Yes, Nervos mining is permitted in Germany. For tax purposes, the usual logic applies: if you mine CKB regularly and with a profit motive, the tax office classifies this as a commercial activity, and the yields generated are subject to tax.
The ongoing costs can be offset - electricity consumption, hosting and the K7 miner reduce the taxable surplus; which levers apply in practice is covered by our article reducing your taxes through crypto mining. Whether mining is generally permitted is answered by each state independently; in assessing your case, a tax advisor can help you further. This is not tax advice.
A Nervos miner is fixed to Eaglesong and therefore only mines Eaglesong coins - practically exclusively Nervos itself, since this algorithm was developed specifically for the Nervos chain.
Even closely related algorithms do not help: the Antminer K7 can compute neither Bitcoin (SHA-256) nor Kadena (Blake2S), because its chips exclusively generate Eaglesong hashes. For every other coin you need the matching device - a model overview per coin is provided by the ASIC miner category.
