CKB Mining
How traditional Nervos CKB mining works
Nervos Layer 1 (CKB, Common Knowledge Base) is proof-of-work. The native token is the CKByte: holding 1 CKB entitles you to 1 byte of state on chain. Consensus is NC-MAX, a Bitcoin-style PoW design with shorter block times (about 8–10 seconds).
Mining uses the Eaglesong hash. CPU/GPU mining is obsolete; current hardware is Bitmain K-series, iBeLink BM-N, and Goldshell CK ASICs.
Nervos mining pools
Eaglesong pools with public ASIC guides:
-
f2pool:
ckb.f2pool.com:4300, account.worker format, ~100 CKB payout threshold. - 2Miners: EU/US/Asia stratum, PPLNS and solo, ASIC setup pages for CK and iBeLink units.
- AntPool: Multi-coin pool with CKB support.
- DxPool: Additional public CKB pool.
Nervos mining algorithm
Eaglesong is a permutation-based hash specified for CKB. It is not Ethash and not SHA-256; you need an Eaglesong ASIC (or a dual-purpose unit whose firmware exposes Eaglesong).
CKB also pays Nervos DAO interest to holders who lock tokens. That is separate from mining: miners receive the block subsidy; DAO is a holder mechanic.

How to set up a Nervos mining rig
-
1. Choose CKB mining hardware
Use an Eaglesong ASIC from the list below (for example Antminer K7, Goldshell CK6, iBeLink BM-N3).
-
2. Set up a CKB wallet
Create a mainnet address starting with
ckbvia Neuron or another listed wallet. Exchange deposit addresses work if the exchange supports CKB withdrawals. -
3. Configure the ASIC to the pool
Enter the pool URL (f2pool uses a username, 2Miners uses the wallet as worker). Save and reboot.
-
4. Be cautious with firmware
Flash only vendor firmware. Eaglesong custom images from random forums are a common theft vector.
-
5. Start mining
Wait for the worker to appear on the pool. Watch temperature: CK and K-series units are datacenter-class, not silent home boxes.
Frequently asked questions
CKB is Nervos’s Layer-1 PoW chain. The CKByte is both the fee token and a claim on on-chain storage. Docs: docs.nervos.org.
No. f2pool and others treat GPU/FPGA as non-competitive. Plan on ASICs.
One CKByte corresponds to one byte of state. Occupied cells lock CKB until the data is removed.
Pick on fee, region, and payout scheme. f2pool and 2Miners publish ASIC connection strings; compare current hashrate on MiningPoolStats.
