The Subnet Miner
A Bittensor mining course
Compete for Bittensor's miner rewards, without losing TAO to rookie mistakes
A self-paced course with a 30-day plan, rebuilt for the 2026 network: 34 written lessons with every command, from your first wallet to a monitored miner.
The upside
Bittensor is built to reward the miners who do the most useful work
In Bitcoin mining, rewards go to raw hashing power. On Bittensor, each subnet is an open competition around one useful task, such as serving AI models, training them, collecting data or forecasting. Validators score every miner's work, and the network turns those scores into rewards.
41% goes to miners
Each block, every subnet issues new tokens for its participants and reserves 41% of them for its miners. Validators and their stakers share another 41%, and the subnet owner receives 18%.
Paid out every epoch
Rewards are settled at the end of each epoch, about every 72 minutes with default settings, and credited to each miner's hotkey.
Shared by merit
Your share depends on how validators score your work against other miners'. Improve your miner, and your share can grow.
Rewards are paid in each subnet's own token, and they are not guaranteed: your share depends on your results, and token values can fall as well as rise. But the reward is real, it is written into the protocol, and it goes to the miners whose work scores best. This course trains you to compete for it, and to avoid the mistakes that cost new miners their TAO.
The problem
Most Bittensor mining guides describe a network that no longer exists
In July 2026, Bittensor rewrote the rules a miner lives by. The SDK and btcli merged into a single new version with new commands. The networking layer most tutorials build on was removed. Registration became burn-only at a floating price, some subnets began locking collateral, and a new emission gate started starving the bottom of the subnet list.
Yet most guides still teach --wallet.name, proof-of-work registration and Axon code. Follow them and the best case is an error message. The worst case is real TAO spent on a registration that never earns a thing.
The expensive mistakes in mining are rarely about AI: they are about keys, ports, timing and choosing the wrong subnet. New miners typically lose TAO in five ways:
They register before the miner is ready, and their immunity runs out before validators ever score them.
They pick a subnet deep below the emission gate, where the whole pot is a trickle.
They publish the wrong IP or an internal port, and sit invisible while the clock runs.
They put a coldkey on a server full of untrusted code.
They run a "one-click" script that asks for a seed phrase.
The method
Eight steps from a first wallet to a miner that stays registered
Understand how you get paid. Emissions, the 41% miner share, incentive, epochs, and why the numbers most people watch are deprecated.
Lock down your keys. Our first rule: the coldkey stays cold, and never touches a mining server.
Choose your subnet with a scorecard. Ten criteria scored from 0 to 2, plus three deal-breakers that rule a subnet out before you spend anything.
Build a hardened machine. A server baseline, Python environments that don't collide, and your own node when you need one.
Rehearse twice, register once. Drills on a local chain, then a testnet run with six exit criteria.
Register inside your runway. Never before your miner is ready, and always with the burn and collateral split read in advance.
Compete like a validator. A local harness that scores you with the validator's own rules, so you improve in minutes instead of days.
Run it like a business. A cost sheet, a collection policy, clean records and exit rules written before you need them.
Each lesson ends with one concrete action, so you finish the course with a working setup, not a pile of notes.
Built on the source
Every command comes from the official documentation and the chain's own code
The Subnet Miner was built from the official Bittensor documentation and the source code of the chain and its SDK as they stand in autumn 2026, not from forum threads or old videos. Every command uses the current Bittensor 11 syntax. When the documentation and a popular guide disagree, the course follows the documentation and tells you why.
It covers each 2026 change by name:
Bittensor 11, one package for the SDK and btcli, with its new commands and flags
Hotkey-signed HTTP between validators and miners, replacing Axon and Dendrite
Burn-only registration at a floating price, and how to time it
Registration collateral, and how to read the burn and lock split before paying
The emission gate, and what it changes in choosing a subnet
Deprecated metrics, and the two numbers a miner should actually watch
Price-ranked subnet deregistration, a risk most miners never check

WHO IT’S FOR
✅ This course is for you if
You are comfortable in a terminal, or ready to become so
You want to compete seriously for the network's rewards, on hardware you own or rent
You will rehearse before you spend TAO
You want to understand the rules, not just copy commands
❌ It's not for you if
You are looking for passive income or guaranteed returns
You want a one-click script that does everything for you
You want token picks or price prediction
You don't want to learn any Linux at all
Straight talk
Honest about the risks, serious about the method
Mining is competitive, and rewards are never guaranteed. Many miners spend more on registrations and hardware than they ever earn.
That's why this course gives you a method, not a promise: read a subnet, rehearse before you spend, and follow your own numbers. You'll still have to put in the work, but you won't be doing it blind. From the subnet scorecard and rehearsal drills to the monitoring scripts and cost sheet, you get the tools to move forward with confidence.
The course won't hand you token tips or price predictions. It never asks for your keys or your seed phrase, and neither should anyone else.
Questions
Answers before you enroll
Do I need to be a machine-learning engineer?
No. You need to be comfortable with a terminal and willing to learn some Linux. Some subnet families reward data engineering, forecasting or plain operational discipline more than machine-learning research, and the scorecard makes you choose a subnet that fits your skills. If you have never opened a terminal and don't want to, this course is not the right place to start.
How much can I earn?
Nobody can honestly answer that. What we can tell you is how the reward works: 41% of every subnet's emissions go to its miners, paid out every epoch and split according to validators' scores. How much reaches you depends on the subnet, your competition, your costs and token prices, and it is never guaranteed. The course gives you a cost sheet and exit rules so that you know, with your own numbers, whether your miner covers its costs.
Isn't all of this in the official documentation?
The official documentation is excellent, and the course points you to it constantly. It is written as a reference, organized by feature. The course turns it into a path, in the order you need it, and adds what a reference doesn't: the scorecard, rehearsal drills with exit criteria, the go-live checklist, monitoring scripts and the business side.
What hardware do I need?
It depends on the subnet: some run on a CPU server, others need data-center GPUs. You don't buy or rent anything before Module 4, and the course includes rental price ranges from October 2026 so you can budget before you commit.
Will it be outdated next month?
Commands can change. The course uses the current Bittensor 11 syntax and teaches you to check everything against the official documentation and release notes. The method itself, from the scorecard to the rehearsals, the runway, the measurement and the cost sheet, does not depend on a version.
Is my TAO safe?
No course can guarantee that, and anyone who does is selling something. What this course does is put security first: a full module on keys, the rule that your coldkey never touches a mining server, and drills for the day something goes wrong.
Does it work on Windows?
Miners run on Linux or macOS. On Windows, wallet operations work under WSL 2, and your miner runs on a rented Linux server, which the course shows you how to set up from zero.
Is this investment advice?
No. It is an operations course: how to run a miner, measure it and account for it. It does not recommend tokens, exchanges or trades, and it does not predict prices.
Is the course affiliated with Bittensor?
No. The Subnet Miner is an independent course by Raizora. It is not affiliated with or endorsed by Bittensor, the Opentensor Foundation, the Rao Foundation or any subnet team.
How long does it take?
The course includes a 30-day plan at about an hour a day on weekdays, with longer sessions at weekends. Testnet rehearsals often take longer than planned, and the plan tells you to let them.
