An independent guide to TAO / October 2026

What is Bittensor?

Bittensor is an open network that pays people in a cryptocurrency called TAO for producing useful AI services, and uses dozens of competing marketplaces called subnets to decide whose work is best.

01 / Bittensor in 60 seconds

A market where machines compete to be useful.

Bitcoin pays computers to secure a ledger. Bittensor borrows that idea and points it at something else: it pays computers to do AI work, then lets an open market judge the results.

There is no single "Bittensor AI". The network is a blockchain that keeps score and hands out rewards. The actual work happens in subnets, each of which is its own contest with its own rules: one rents out GPUs, another serves AI models, another hunts for drug candidates, another detects deepfakes.

Everything on this page is educational. It is not a recommendation to buy, sell or stake anything.

  1. A subnet sets a taskEach subnet owner writes the rules for one kind of digital work, such as running AI models or forecasting prices.
  2. Miners do the workMiners are computers (and the people who run them) that compete to produce the best output for that task.
  3. Validators grade itValidators test the miners and publish scores to the blockchain. Their influence depends on how much stake backs them.
  4. The chain pays outAn algorithm called Yuma Consensus combines the scores and splits newly created tokens between miners, validators, stakers and the subnet owner.
  5. Holders steer the flowAnyone holding TAO can stake it into the subnets they believe in, which helps decide where future rewards go.
  6. Supply is cappedOnly 21 million TAO will ever exist, released on a halving schedule modelled on Bitcoin's.

02 / Origins

From a Bitcoin-inspired idea to a live network.

Bittensor's best-known founder is Jacob Steeves, an engineer who previously worked at Google and who is known online as "Const". He has said that studying Bitcoin's incentives in the mid-2010s led him to ask whether the same design could reward machine intelligence instead of hashing. In 2019 he was joined by Ala Shaabana, a computer scientist with a PhD from McMaster University, and the project was incubated with support from the crypto investment firm Polychain Capital.

The ideas were set out in a whitepaper titled "Bittensor: A Peer-to-Peer Intelligence Market". The paper is credited to Yuma Rao, a pseudonym. Nobody has publicly confirmed who Yuma Rao is, in the same way that Bitcoin's Satoshi Nakamoto has never been identified. The name lives on in Yuma Consensus, the algorithm at the heart of the network.

The founders set up the Opentensor Foundation to build and steward the software. The first version of the network, codenamed Kusanagi, went live in January 2021. It was halted a few months later to fix consensus problems and relaunched as Nakamoto in November 2021. In March 2023 the chain migrated to Finney, the network that still runs today.

The "fair launch"

No pre-mine, no token sale

Bittensor did not hold an ICO and did not set aside a block of tokens for founders or investors. Like Bitcoin, the only way to obtain TAO at the start was to earn it by taking part in the network. Early backers, including venture firms, got their holdings by mining and validating, or by buying from people who did.

That does not mean ownership is evenly spread. Early participants faced little competition and accumulated a great deal, which is one of the criticisms covered in the risks section.

Why "Bittensor"?

Bit + tensor

A tensor is the multi-dimensional array of numbers that neural networks are built from. The name signals the ambition: Bitcoin's economic model, applied to machine learning. The token symbol TAO is written with the Greek letter tau (τ).

Three networks

Kusanagi, Nakamoto, Finney

The codenames nod to Motoko Kusanagi of the anime Ghost in the Shell, Bitcoin's creator Satoshi Nakamoto, and Hal Finney, who received the first Bitcoin transaction.

04 / How it works

A blockchain that keeps score.

Bittensor has two layers. At the bottom is Subtensor, a proof-of-stake blockchain built with the Substrate framework (the same toolkit used by Polkadot). It produces a block roughly every 12 seconds, records who holds what, and runs the reward logic. Since late 2024 it has also supported Ethereum-style smart contracts through an EVM layer.

On top sit the subnets. The heavy AI computation never touches the chain. Miners run models and hardware off-chain; only the scores and the resulting payments are recorded on-chain.

Role 01

Miners

Produce the commodity the subnet asks for: answers, compute, predictions, storage. Paid according to how well they score.

Role 02

Validators

Test miners and submit a list of scores, called weights. Earn more when their judgments match the consensus.

Role 03

Subnet owners

Design the incentive mechanism: the task, the test and the scoring code. Receive 18% of their subnet's emissions.

Role 04

Stakers

Back validators with TAO or subnet tokens and share in the rewards. Their stake gives validators their voting weight.

Yuma Consensus, in plain English

Imagine a panel of judges at a competition. Each judge scores every contestant. To stop one biased judge from handing a friend the prize, the panel looks at where the stake-weighted majority of judges landed for each contestant and clips any score above that level. The contestant's final mark is built from the clipped scores.

That is Yuma Consensus. Validators are the judges, miners are the contestants, and a judge's voting power depends on the stake behind them. Validators who score in line with the eventual consensus build up "bonds" in the miners they spotted early and earn more. Validators who score wildly out of line earn less.

The process repeats every tempo, which is 360 blocks or about 72 minutes by default. At the end of each tempo the subnet's newly created tokens are divided: 18% to the subnet owner, 41% to miners and 41% to validators and the people staking with them.

What counts as "good work" is not decided by the blockchain. Each subnet owner writes that definition into the subnet's incentive mechanism. A well-designed mechanism rewards real quality; a poorly designed one gets gamed. Much of Bittensor's history is a story of subnets learning that lesson.

05 / Subnets

One network, many contests.

A subnet is a self-contained competition for one kind of digital commodity. Subnets were opened to outside teams in October 2023; before that the network ran a single task. Each subnet has a number (its netuid), an owner, a limited set of miner and validator slots, and since 2025 its own token.

Launching a subnet means paying a registration cost in TAO that rises and falls with demand. The number of slots is capped. For most of 2025 and 2026 that cap was 128, and when the network is full the weakest subnet by token price can be deregistered to make room, after an immunity period for newcomers. An increase toward 256 slots has been proposed and reported during 2026, though public directories still listed about 128 active subnets in October 2026.

Subnet 0, known as Root, is special. It has no miners. It is where TAO holders stake for network-wide exposure rather than betting on a single subnet.

Subnets are not permanent. Teams rebrand, sell, pivot or leave, and a netuid can be reused by an entirely different project. Treat the directory below as a snapshot from October 2026 and check a live explorer before relying on it.

06 / Tokenomics

Twenty-one million, released by halving.

TAO copies Bitcoin's headline numbers on purpose: a hard cap of 21 million and a reward that halves over time. The detail of when it halves is different.

21,000,000Maximum TAO
0.5 τNew TAO per block since Dec 2025
~3,600New TAO per day
~12 sBlock time

From launch, the chain created 1 TAO per block, or about 7,200 a day. In mid-December 2025 the first halving cut that to 0.5 TAO per block, about 3,600 a day.

Bitcoin halves every 210,000 blocks. Bittensor instead halves when total issuance crosses set thresholds: half the supply (10.5 million), then three quarters (15.75 million), and so on. If nothing else happened this would work out at roughly four years between halvings.

Something else does happen. Fees for registering miners and subnets are recycled: the TAO is handed back to the pool of tokens yet to be issued. Recycling lowers the issuance count, which pushes later halvings further into the future. So the dates of future halvings are estimates, not fixed appointments.

There was no allocation to a team, foundation or investors at genesis. Every TAO in existence was created as a block reward. New TAO does not go straight to miners any more; since 2025 it is injected into subnet liquidity pools, and participants are paid in subnet tokens. The next two sections explain that.

Block reward by halving era // select an era

Progress toward 21M: waiting for live data

07 / Dynamic TAO

Every subnet gets its own token.

Until early 2025, a small group of large validators on the root network voted on how much TAO each subnet received. Critics said this concentrated power and invited favouritism. In February 2025 the network replaced it with Dynamic TAO, usually shortened to dTAO.

Under dTAO every subnet has its own token, generically called an alpha token. Each subnet also has a liquidity pool holding two things: TAO and that subnet's alpha. The ratio between them is the alpha token's price. There is no order book and no company setting prices; an automated market maker does it with a formula.

When you stake TAO into a subnet, you are swapping it for alpha through that pool. Your TAO goes in, alpha comes out, and the price of alpha moves up. Unstaking is the reverse. Because it is a swap, the value of your position rises and falls with the alpha price, and large trades move the price against you (slippage). Each alpha token has its own 21 million cap and its own halving curve.

Who gets the emissions?

The market now decides how new TAO is shared between subnets, but the formula has been rewritten more than once:

  • February 2025: a subnet's share followed the price of its alpha token.
  • November 2025: "TAO flow" replaced price. Shares followed net staking inflows, smoothed over time, and subnets with net outflows received nothing.
  • 2026: further overhauls. The current documentation describes shares based on a smoothed alpha price, reduced for subnets that burn their miner rewards, plus an "emission gate" that concentrates rewards on roughly the top 32 subnets. In June 2026 emissions were also switched off for dozens of subnets judged inactive.

Expect this to keep changing. The direction has been consistent, though: fewer rewards for idle subnets, more for those attracting real demand.

This pool starts with 10,000 TAO and 100,000 alpha. Drag to stake TAO and see what the pool gives back.

The bigger your stake relative to the pool, the worse your average price. That is slippage, and it applies again when you unstake.
Why it matters

Staking became investing

Before dTAO, staking was a fairly uniform yield. After it, staking into a subnet is a judgment about that subnet's future. Alpha tokens can lose most of their value, and several have.

08 / Staking

Two ways to put TAO to work.

Staking means delegating tokens to a validator. You keep ownership, the validator gains voting weight, and you share the rewards minus the validator's commission. There are two very different places to do it.

Option A

Root staking (Subnet 0)

You stake TAO to a validator on the root network and your position stays denominated in TAO. You are not exposed to any single subnet's token price. Root stakers receive a slice of the rewards from across the subnets.

Since the "Root Reborn" upgrade in August 2026, that yield accrues as subnet tokens held in a per-validator basket and is only converted when the staker claims it, rather than being sold for TAO every block. A planned feature that would let validators actively choose which subnets their basket backs was not switched on at launch.

Option B

Subnet staking (alpha)

You swap TAO for a subnet's alpha token and stake that with a validator on the subnet. Rewards are paid in more alpha. Potential returns are higher and so is the risk: your position moves with the alpha price, and thin pools mean slippage on the way in and out.

Subnet stake also counts for more in consensus. Within a subnet, TAO staked at root is weighted at 18% of the value of alpha staked directly.

Things beginners often miss

  • Two keys. Bittensor wallets have a coldkey that holds funds and a hotkey used for day-to-day operations by miners and validators. As a staker you only need a coldkey. Never share its seed phrase.
  • Validators charge commission. The "take" varies by validator. Compare before delegating.
  • No fixed lock-up, but not free. Ordinary staking can be undone at any time, but unstaking from a subnet is a swap back to TAO at whatever the price is then.
  • Yields are not interest. They are a share of newly created tokens. A high percentage paid in a falling token can still be a loss.
Snapshot

How much is staked?

A May 2026 report by FalconX and SubnetStats estimated that about 70% of all TAO was staked: roughly half of supply at root and about a fifth in subnets. These figures move constantly.

New in 2026

Conviction locks

After a major subnet team left abruptly in April 2026, the network introduced "Conviction". In its first phase, live since May 2026, subnet owners' rewards are locked automatically and owners must post a public on-chain request before unlocking them, giving holders warning of large sales.

09 / People and organisations

Who is behind it.

Bittensor has no company at the top, but a fairly small set of people and teams have shaped it. Roles below are as publicly reported up to October 2026.

Co-founder

Jacob Steeves ("Const")

Former Google engineer who conceived Bittensor and wrote much of its early code. He led the Opentensor Foundation until the chief executive role was removed in February 2026, and remains the most influential contributor, proposing major protocol changes and building subnets.

Co-founder

Ala Shaabana

Computer scientist who joined in 2019 and helped launch the network and foundation. He later co-founded Crucible Labs, which makes a Bittensor wallet and staking tools.

Whitepaper author

Yuma Rao

The pseudonymous name on the Bittensor whitepaper. The identity behind it has never been publicly confirmed. Yuma Consensus and DCG's Yuma subsidiary both take the name.

Founding organisation

Opentensor Foundation

The non-profit that built and maintained the chain and software from launch. In 2026 it stepped back from formal control and handed over its code repositories.

Core development

Latent

Latent Holdings, a company associated with Jacob Steeves, operates the TAO.app explorer. Since April 2026 the Bittensor software kit and command-line tool have been maintained under the Latent name instead of the foundation. Critics note there is no second independent team maintaining that software.

Subnet builder

Rayon Labs

The team behind several prominent subnets, including Chutes (model hosting) and Gradients (fine-tuning).

Subnet builder

Macrocosmos

A studio co-founded by Will Squires and Steffen Cruz that runs several subnets, among them Apex, IOTA and Data Universe.

Subnet builder

Manifold Labs

Developer of Targon, the confidential-compute subnet. It has reported raising a $10.5 million Series A round.

Investor and builder

Yuma and Barry Silbert

Digital Currency Group, founded by Barry Silbert, has backed Bittensor since 2021. Its subsidiary Yuma, launched in November 2024 with Silbert as chief executive, incubates subnets, runs a large validator and manages subnet funds.

Early backers

Polychain Capital and dao5

Polychain incubated the project in 2019. dao5, founded by former Polychain partner Tekin Salimi, is another early holder. Both acquired TAO through the network, since there was no token sale.

Asset manager

Grayscale

Runs the Grayscale Bittensor Trust and has filed to convert it into an exchange-traded product. Also publishes research on the network.

Former subnet builder

Covenant AI and Sam Dare

Built Templar, Basilica and Grail, and trained a 72-billion-parameter model on the network. Left in April 2026 after a public dispute over governance; see the risks section.

10 / Ecosystem and institutions

How traditional finance has approached TAO.

Trusts and ETF filings

Grayscale Bittensor Trust

Grayscale runs a TAO trust that trades over the counter in the United States under the ticker GTAO. On 30 December 2025 it filed with the SEC to convert the trust into a spot exchange-traded product, and amended that filing in April 2026. As of early October 2026 it had not been approved. That month Grayscale added Coinbase as a second custodian alongside BitGo.

European products

Staked TAO ETP

In October 2025 Deutsche Digital Assets and the Swedish broker Safello listed a physically backed, staked Bittensor exchange-traded product on the SIX Swiss Exchange under the ticker STAO.

Subnet funds

Yuma Asset Management

DCG's Bittensor subsidiary Yuma launched an asset management arm in October 2025 with two funds for accredited investors that hold baskets of subnet tokens, anchored by a reported $10 million from DCG.

Listed companies

TAO treasury companies

A handful of publicly traded companies hold TAO as a treasury asset. CoinGecko's tracker lists TAO Synergies (Nasdaq), xTAO (TSX Venture), TaoWeave (formerly Oblong) and Safello Group. Holdings change; check the tracker in the sources.

Exchanges

Major listings

TAO was listed by Binance in April 2024 and by Coinbase in February 2025, and trades on Kraken, KuCoin, OKX and others. In June 2026 Kraken added seven subnet tokens to its public listing roadmap, a first for a large exchange, without committing to dates.

On-chain finance

EVM and DeFi

The EVM layer lets Ethereum-style applications run on Bittensor. Early projects include bridges, liquid-staking tokens and trading front ends for subnet tokens. These are young and carry smart-contract risk.

Institutional products are not a judgment on quality. A trust or ETP simply gives investors another way to hold an asset, with its own fees and risks.

11 / Roadmap and future

What is planned, and what is still open.

Bittensor has no single binding roadmap. What follows are directions that core contributors have published or shipped. Plans in this ecosystem change often, and proposals are not promises.

Shipped / 2026

Stepping back of the foundation

In February 2026 the Opentensor Foundation announced it was giving up privileged control. The chief executive role was removed, chain security moved toward nominated proof of stake, and validators and subnet owners gained the ability to ratify or veto upgrades. In April 2026 the core code repositories were transferred to a separate team, Latent.

Shipped / 2026

Tighter emissions

A May 2026 refactor, the June cleanup of inactive subnets and the emission gate all push rewards toward a smaller number of active subnets.

Shipped in part / 2026

Root Reborn and Conviction

Root yield now accumulates in validator baskets. Validator-curated baskets and later phases of Conviction, including a way for token holders to replace a subnet's owner, were still to come at the time of writing.

Proposed / to end 2027

18-month decentralisation plan

Published in June 2026, the plan targets December 2027 and includes bringing back real competition between validators, two-way subnet liquidity pools, and a "belief mechanism" giving alpha holders a direct vote on subnet decisions.

Open question

More subnets, or fewer?

The community is pulling in two directions: expanding the number of subnet slots toward 256, while concentrating emissions on a few dozen. How those fit together is unresolved.

Open question

Real revenue

Several subnets now report meaningful income from outside customers, mostly for compute and inference. Most figures are self-reported and unaudited. Whether subnets can earn more than they receive in emissions is the long-term test.

Closest to Bitcoin in economics

The fixed cap, the halving and the absence of a pre-mine are deliberate echoes of Bitcoin. The difference is what the reward buys. Bitcoin pays for security through energy spent. Bittensor tries to pay for output that has value in its own right, which is far harder to measure.

Broader than a compute market

Render and Akash match buyers with hardware and charge for it. Bittensor includes compute subnets that do the same, but it also funds contests with no customer yet, paid for by token emissions. That makes it more flexible and more dependent on good incentive design.

Write your seed phrase on paper and never type it into a website or share it with anyone, including "support". TAO lives on its own chain: sending it to an Ethereum or Bitcoin address will lose it. Send a small test amount first.

14 / Where to buy and how to stake

A neutral, step-by-step walkthrough.

This explains the mechanics. It is not a suggestion that you should buy TAO. Availability depends on your country, and exchanges can add or remove assets at any time.

Exchanges that list TAO

Shown in no particular ranking; links go to each exchange's own home page. Confirm that TAO is available in your region before opening an account.

Buying

  1. Pick a regulated exchange available where you live and create an account directly on its official site. Expect identity checks.
  2. Fund the account by bank transfer or card, or deposit crypto you already own.
  3. Buy TAO. Check the ticker is TAO and the name is Bittensor. Many unrelated tokens use similar names.
  4. Decide where to hold it. Leaving coins on an exchange is simple but means trusting the exchange. Withdrawing to your own wallet gives you control and responsibility.

Staking from your own wallet

  1. Install a wallet from the wallets guide and back up the seed phrase offline.
  2. Withdraw a small test amount from the exchange to your wallet address on the Bittensor network, then the rest.
  3. Choose root or a subnet. Root keeps you in TAO. A subnet swaps you into its alpha token. Read the staking section first.
  4. Choose a validator and check its commission and track record on an explorer such as Taostats or TAO.app.
  5. Confirm the transaction in your wallet. Keep a little TAO unstaked to pay network fees later.

15 / Risks and criticisms

The case against, stated fairly.

Bittensor attracts strong opinions. These are the main concerns raised by critics and, in several cases, by people inside the ecosystem.

Centralisation and governance

For most of its life, upgrades were controlled by a three-person "triumvirate" linked to the Opentensor Foundation. In April 2026 Covenant AI, then one of the largest subnet operators, quit the network and its founder described the governance as decentralisation in name only, alleging that co-founder Jacob Steeves held effective control. Steeves disputed many of the allegations. Reforms have followed, but they are recent and incomplete.

Concentrated stake

A small number of validators and early holders control a large share of stake. Because voting weight follows stake, they have outsized influence over scores, rewards and upgrades.

Subnet quality

Many subnets have produced little of outside value. In April 2026 one analysis found more than half of all subnets were burning nearly all of their miner rewards, and in June 2026 emissions were cut off for dozens deemed inactive.

Gaming the incentives

Miners optimise for whatever is measured. If a subnet's test is weak, miners will pass the test without doing useful work, copy each other, or collude with validators. Designing a mechanism that cannot be gamed is hard and never finished.

Subnet owner risk

A subnet depends heavily on its team. When Covenant AI left, it sold its subnet tokens and their prices fell sharply within hours, pulling TAO down with them. A separate January 2026 incident on one subnet was reported by one analyst to have cost users close to $3 million. Conviction locks are a response, not a cure.

Security history

On 2 July 2024 an attacker drained about 32,000 TAO, then worth roughly $8 million, from users whose keys had been stolen by a malicious copy of the Bittensor software package uploaded to the Python package index. Validators put the chain into a "safe mode" that stopped all transactions while the code was reviewed. The halt limited losses and also showed that a small group could stop the network.

Complexity

Two kinds of key, more than a hundred tokens, automated pools, changing emission formulas. The system is hard to understand even for experienced crypto users, and misunderstanding it can be expensive.

Constant rule changes

Core economics have been rewritten several times in two years. Each change creates winners and losers and makes long-term planning difficult for subnet builders and stakers.

Market and regulatory risk

TAO and alpha tokens are volatile, and alpha pools can be thin. Rules for staking and tokens differ by country and are still evolving. You can lose everything you put in.

The other side. Supporters reply that the network has shipped working products, that several subnets report paying customers, that the foundation did give up formal control in 2026, and that open competition is exactly how weak subnets get weeded out. Both views can be true at once.

16 / Glossary

The jargon, decoded.

Alpha token
The generic name for a subnet's own token. Each subnet has one, capped at 21 million.
AMM (automated market maker)
A pool of two tokens that sets a price by formula. Every subnet has one pairing TAO with its alpha token.
btcli
The Bittensor command-line tool for managing wallets, staking and running nodes.
Coldkey
The key that holds your funds and stake. Keep it offline and never share its seed phrase.
Conviction
A 2026 mechanism that locks subnet owners' rewards and makes them signal on-chain before unlocking.
Delegation
Assigning your stake to a validator so it counts toward that validator's weight. You keep ownership.
Deregistration
Removal of the weakest subnet when all slots are full and a new one registers.
dTAO (Dynamic TAO)
The February 2025 upgrade that gave every subnet a token and let markets, not a committee, direct emissions.
Emissions
Newly created tokens distributed as rewards each block.
Emission gate
A rule that cuts off or reduces emissions for subnets below a demand threshold.
EVM
Ethereum Virtual Machine. Bittensor's EVM layer lets Ethereum-style smart contracts run on Subtensor.
Finney
The current Bittensor main network, live since March 2023.
Halving
A 50% cut in new TAO per block, triggered when total issuance crosses set thresholds.
Hotkey
An operational key used by miners and validators to sign day-to-day actions. It does not hold your main balance.
Incentive mechanism
A subnet's rulebook: the task, how validators test miners, and how scores are calculated.
Metagraph
The on-chain record of a subnet's state: who is registered, their stake, scores and rewards.
Miner
A participant that produces a subnet's commodity and is paid according to validator scores.
Netuid
A subnet's ID number, such as 64 for Chutes.

Returning TAO paid in registration fees to the unissued pool, which delays future halvings.
Root (Subnet 0)
The special subnet with no miners where holders stake TAO for network-wide exposure.
Slippage
The difference between the quoted price and the price you actually get, caused by your own trade moving the pool.
Stake

18 / FAQ

Common questions.

What is Bittensor in simple terms?

Bittensor is an open network that rewards people with a cryptocurrency called TAO for producing useful AI services. The work is organised into subnets, each a separate competition where miners do a task, validators score them, and the blockchain pays out according to those scores.

Who created Bittensor?

Bittensor was co-founded by Jacob Steeves and Ala Shaabana, who set up the Opentensor Foundation to develop it. The whitepaper is credited to Yuma Rao, a pseudonym whose identity has not been publicly confirmed. The network launched in 2021.

What is TAO and how many will exist?

TAO is the native token of the Bittensor network. Its supply is capped at 21 million. New TAO is created with each block and the amount halves over time. The first halving took place in December 2025, reducing issuance from about 7,200 to about 3,600 TAO per day.

What is a Bittensor subnet?

A subnet is an independent marketplace for one kind of digital work, such as running AI models, renting GPUs, storing data or making predictions. Each subnet has an owner who sets the rules, miners who do the work, validators who grade it, and its own token.

What is Dynamic TAO (dTAO)?

Dynamic TAO is an upgrade from February 2025 that gave every subnet its own alpha token and a liquidity pool pairing it with TAO. Staking TAO into a subnet swaps it for that alpha token. Market demand for subnet tokens, rather than a committee of validators, now steers how new TAO is shared between subnets.

Is Bittensor the same as Bitcoin?

No. Bittensor copies parts of Bitcoin's economics, including the 21 million cap, halvings and a launch with no pre-mine. But Bitcoin is a payment network secured by proof-of-work, while Bittensor is a proof-of-stake chain that rewards AI-related work judged by validators.

How do you stake TAO?

You stake by delegating TAO to a validator from a compatible wallet. Staking on the root network keeps your position in TAO. Staking into a specific subnet converts your TAO into that subnet's alpha token, which carries price risk and slippage. Validators charge a commission on rewards.

Where can you buy TAO?

TAO is listed on several large exchanges, including Binance, Coinbase, Kraken, KuCoin and OKX. Availability depends on your country. Always use the exchange's official website and check you are buying Bittensor with the ticker TAO.

Has Bittensor been hacked?

In July 2024 attackers uploaded a malicious copy of the Bittensor software package that stole users' keys, then drained about 32,000 TAO worth roughly $8 million. Validators halted the chain while the code was reviewed. The blockchain's own consensus was not broken; the theft came through compromised software on users' machines.

Is Bittensor decentralised?

Partly, and it is disputed. For years upgrades were controlled by a small group tied to the Opentensor Foundation, and stake is concentrated among a few large validators. In 2026 the foundation stepped back and published a plan to decentralise governance by the end of 2027, after a major subnet team left accusing the project of centralised control.

Is there a Bittensor ETF?

Not in the United States as of October 2026. Grayscale filed in December 2025 to convert its Bittensor trust into an exchange-traded product and the application was still pending. In Europe a staked TAO exchange-traded product has traded on the SIX Swiss Exchange since October 2025.

Is TAO a good investment?

This site does not give investment advice. TAO is a volatile crypto asset, the network's rules change often, and subnet tokens can lose most of their value. Anyone considering it should understand the risks, read primary sources and only use money they can afford to lose.
