Best Mining Pool for NerdMiner: Solo Options Compared
The best mining pool for NerdMiner must accept shares from an ESP32-class device. Most ASIC-oriented pools use share targets that make a NerdMiner invisible in their statistics. This comparison covers compatible solo endpoints, setup checks, fees, and realistic block odds.
Why NerdMiner Needs a Low-Difficulty Pool
NerdMiner runs Bitcoin mining code on supported ESP32 boards. The firmware connects to a Stratum server and tests block-header hashes against the Bitcoin target.
Pool shares use an easier target than Bitcoin blocks. They let the server confirm that a worker remains active and measure its contributed work. A low-difficulty share is not a partial block reward and does not make the network target easier.
An incompatible pool may accept the connection and send jobs without recording useful worker statistics. That is why login success alone cannot confirm compatibility.
A suitable solo pool supplies mining jobs and records low-difficulty shares. If the device finds a valid Bitcoin block, the pool handles submission under its published reward and fee rules.
Low share difficulty improves monitoring. It does not improve the chance attached to any individual hash.
How to Choose a Pool for NerdMiner
Check low-difficulty support before comparing any other feature. A pool built only for ASIC miners may never record an ESP32 worker.
- Low-difficulty support. The operator should name NerdMiner, ESP32 devices, or similar micro miners.
- Accepted-share reporting. The dashboard should show that shares reach the server.
- Fee policy. Check what the operator deducts if the device finds a block.
- Worker lookup. Address-based statistics should show the worker, best share, and recent activity.
- Connection stability. Repeated disconnects can leave the device working on outdated jobs.
The same compatibility check matters when choosing a pool for other small miners. A familiar pool name does not compensate for an unsuitable share target.
NerdMiner-Compatible Pools Compared
The NerdMiner firmware lists several recommended low-difficulty endpoints. Solo CKPool appears for contrast because the same documentation classifies it as a standard pool without compatible low-difficulty shares.
| Pool | Server address | Published fee | Low-difficulty status | Practical fit |
|---|---|---|---|---|
| Official NerdMiner pool | pool.nerdminers.org:3333 |
0% | Modified for NerdMiner-level difficulty | First setup or stock firmware |
| NerdMiner.io | pool.nerdminer.io:3333 |
Check current terms | Listed by the firmware project | Alternative NerdMiner endpoint |
| Public Pool | public-pool.io:3333 |
Check current terms | Listed by the firmware project | Open-source and DIY miners |
| Solo CKPool | stratum.ckpool.org:3333 |
2% | Initial share difficulty 10,000 | ASIC solo mining, not ESP32 monitoring |
The firmware list confirms compatibility intent, not permanent availability. Pool configuration and terms can change. Test each endpoint with the actual device before relying on its dashboard.
The Official NerdMiner Pool
For a first setup, pool.nerdminers.org:3333 has the clearest documented fit. The firmware project labels it as the official pool. Its operator says the pool software was modified to accept the ultra-low difficulty NerdMiner needs.
The service publishes a zero-fee policy for NerdMiner workers. It uses the configured BTC address in the coinbase transaction when building a candidate block.
The dashboard provides pool and address-based worker statistics. Its fields include hashrate, best difficulty, runtime, and the latest submitted share. A worker name can follow the BTC address after a dot.
This endpoint removes the main compatibility question. It also gives you a direct way to confirm that the server records the device’s work.
A working setup shows submitted shares or an updated best-share value, not only an authorized connection.
Public Pool: The Broader Alternative
The NerdMiner firmware lists public-pool.io:3333 among its recommended low-difficulty pools. It describes Public Pool as an open-source Bitcoin solo pool for open-source miners.
That broader focus may suit a desk with several DIY mining devices. The official NerdMiner pool has a narrower purpose and explicitly restricts access to NerdMiner-class hardware.
Do not judge Public Pool by connection status alone. Confirm that the worker appears, submitted shares increase, and the best-share value changes. If those fields remain empty, return to a pool that explicitly documents its live NerdMiner configuration.
Public statistics use the mining address and may also expose worker labels. A dedicated receiving address can keep those records separate from other wallet activity.
Why Standard Solo Pools Fall Short
Solo CKPool accepts Stratum miners at stratum.ckpool.org:3333, but its published settings do not suit NerdMiner monitoring. The service starts at share difficulty 10,000 and does not recommend Bitcoin mining below 100 GH/s.
An ESP32 worker may connect and receive jobs without appearing promptly in the user statistics. The missing statistics do not change the network-level chance of finding a block. They make the endpoint poor for confirming that a micro miner works.
Solo CKPool charges a 2% fee and targets ASIC solo miners. It remains a valid service for compatible hardware, but the NerdMiner firmware places it among standard pools without low-difficulty support.
Apply the same test to other services. If the operator does not document micro-miner support, verify accepted shares before leaving the device connected.
Realistic NerdMiner Block Odds
Expected solo block time can be estimated with:
network difficulty × 2^32 ÷ miner hashrate
The result is an average number of seconds, not a countdown. Use the device’s measured hashrate and a current network-difficulty value when calculating it.
A static estimate becomes stale when network difficulty or device performance changes. More importantly, the average does not predict when a specific miner will succeed. Each tested hash has its own small chance of meeting the Bitcoin target.
At ESP32-class hashrate, the expected wait sits far outside a practical financial horizon. NerdMiner still performs real hashing, but it should be treated as a learning device and lottery-style experiment.

Running longer produces more attempts. It does not make the next hash “due.”
How to Connect NerdMiner to a Solo Pool
Setup needs Wi-Fi credentials, a compatible Stratum endpoint, and a BTC receiving address. Keep the pool lookup open while testing the connection.
- Power the device and connect to its
NerdMinerAPaccess point. - Enter the local Wi-Fi credentials in the configuration page.
- Set the host to
pool.nerdminers.organd the port to3333. - Enter the BTC receiving address in the wallet field. Append
.worker-nameif you need a label. - Use
xif the firmware requires a pool password. - Save the settings, restart the device, and check the address in the pool lookup.
A successful test shows recent worker activity, submitted shares, or a changing best-share value. An active Wi-Fi icon proves only that the device joined the network.
The miner needs a public receiving address. It never needs a seed phrase, private key, exchange password, or wallet login.
Which NerdMiner Pool Should You Use?
Use pool.nerdminers.org:3333 for a stock NerdMiner or a first installation. It documents ultra-low-difficulty support, a zero-fee policy, and address-based worker statistics.
pool.nerdminer.io:3333 and public-pool.io:3333 remain alternatives listed by the firmware project. Check their current terms and verify submitted shares on the live service.
Avoid Solo CKPool when your goal is ESP32 monitoring. Its published share difficulty and hashrate guidance target much faster hardware.
Compare current endpoints in the mining pool directory, then test your chosen pool with the worker lookup.
For most stock devices, the official NerdMiner pool offers the clearest documented compatibility.
Frequently Asked Questions
The official NerdMiner pool identifies a worker by its BTC address. It does not require a private account. The address and worker label may appear in public statistics.
The official pool accepts NerdMiner devices and some similar micro miners. Its documentation says the required ultra-low-difficulty changes do not suit regular mining hardware.
Enter the mining BTC address in the pool’s user lookup. Check for the worker, hashrate, best share, and latest submitted share. Authorization without recorded shares does not confirm a useful connection.
The official zero-fee pool says it puts the configured BTC address in the coinbase transaction. Other services may apply different fees or reward rules.
The firmware’s listed NerdMiner endpoints use port 3333. Enter the BTC address as the wallet or username. On the official pool, append a dot and label to separate worker statistics.
