Coldint / bootstrap is Bittensor subnet 29 (SN29), a project in the Other (subnet incubator) lane. From training subnet to subnet incubator
Coldint registered as a subnet for open, collaborative AI model training. Its team now says that idea is behind them, and the SN29 slot is being repurposed as a place for other people to test their subnet ideas.

What is Coldint / bootstrap (SN29)?
Coldint (Subnet 29) launched in 2024 as a Bittensor subnet for collaborative, distributed AI model training, where miners competed to improve a shared model and could also earn for publishing useful code and fixes. In a June 2026 post in its Bittensor Discord, where the channel has been renamed "bootstrap", the team said the original Coldint idea is behind them and described a new direction for the slot.
The new plan, as the team describes it, is to run SN29 as a host for other people's early-stage subnet ideas. An aspiring subnet owner would run their idea as a "subsubnet" on the SN29 slot, and a fraction of the slot's mining reward would be shared among the miners working that idea. Everything in this section about the new direction comes from that single Discord announcement; it is not yet reflected in the subnet's on-chain identity or its public code.
In plain English: Think of it like a sandbox or incubator for Bittensor subnets. Instead of paying to register your own slot to test an idea, you run it inside someone else's slot first, with real miners attached.

How miners and validators work
Like every Bittensor subnet, SN29 is a two-sided market: miners produce work, validators score it, and emissions follow those weights under the network’s dTAO economics.
- Miners chase the slot's mining rewards, which the team says will continue to be paid in alpha, giving the idea real participants to harden it against.
Project design
Coldint's on-chain identity still reads "Coldint" and still points at the coldint/coldint_validator repository, the codebase for the original collaborative-training subnet. The shift described here is a stated change of direction from the team, not a change the chain or the repositories have caught up with yet. We are treating the Discord announcement as the team's own statement of intent and nothing more, because it is the only source for it.
What the team announced:
The team frames the new model around stake locking. In their words, an aspiring subsubnet owner's SN29 stake would be "safe from large unstakes" because the team intends to lock most, but not all, of the alpha, so that "only root selling and unlocked stake can push the price down." They describe this as depending on an upcoming native stake-locking feature, and the language throughout is future tense: this is a…
Why the project exists
- The problem it solves: Launching a Bittensor subnet is expensive and unforgiving. A new slot costs a TAO burn to register and starts a four-month immunity clock, so early bugs eat into limited runway. The team's pitch is that a builder can shake out those bugs on SN29 first, before committing capital to a real slot.
- The opportunity: If it works as described, an incubator slot lowers the cost of trying a subnet idea: real miners, no registration burn, and feedback from an experienced team, all before raising money for a slot of one's own.
- The Bittensor advantage: A shared slot can attach live economic incentives to an untested idea in a way a private testnet cannot, since testnet miners have nothing real at stake.
- Traction signals: Thin, and worth stating plainly. The plan is described in a single Discord post and is not yet corroborated by code, on-chain identity, or other public sources. On-chain, SN29 currently shows a 0% share of network emissions and one active miner (TaoSwap, snapshot at publish).
What stakers should check before buying alpha
Subnet storytelling is cheap. On-chain and product checks are not. Use the same framework as our subnet metrics guide:
| Check | Why |
|---|---|
| Real product / docs / repo | Separates shipping teams from narrative-only slots |
| Pool depth (TAO) | Your exit door: thin pools amplify slippage |
| Net flows (7d / 30d) | Under flow-based emissions, capital votes with its feet |
| Emission share | Whether the market is funding this subnet right now |
| Ownership concentration | Large holders can move a small alpha market |
| Immunity / deregistration | Post-immunity weak slots can lose the race (see immunity guide) |

Risk factors
- Deregistration: SN29 is well past its four-month network immunity and currently earns a 0% emission share. When a new subnet registers into a full network, the protocol automatically deregisters the non-immune subnet with the lowest EMA price. A subnet at 0% emissions with a low, falling price sits in the exposed group, which matters more than usual here because the incubator pitch depends on the slot continuing to exist.
- Unproven model: The subsubnet incubator is described in a single announcement and is not yet built, documented in code, or reflected on-chain. There is no public way to verify how rewards would be split among "subminers" or how a subsubnet would run inside the slot.
- Dependence on a feature that is not live: The team's price-protection argument rests on locking most of the alpha through a stake-locking capability it describes as upcoming. Today only a small fraction of supply is locked, so the central promise is unverified.
- Liquidity: The pool is thin relative to market cap. Entries and exits can move the price meaningfully, and the team's own pitch concedes that unlocked stake and root selling can still push it down.
How this fits a TAO portfolio
Many holders keep a root vs subnet split: root for calmer TAO exposure, subnets like Coldint / bootstrap for thematic upside (and higher variance). If you use TaoScale, you can size SN29 from your wallet without handing over custody. See non-custodial staking.

FAQ
What does Coldint / bootstrap do on Bittensor?
Think of it like a sandbox or incubator for Bittensor subnets. Instead of paying to register your own slot to test an idea, you run it inside someone else's slot first, with real miners attached.
What is the SN29 alpha token?
When you stake TAO into subnet 29, you receive that subnet’s alpha. Its price versus TAO moves with the subnet’s pool (see what is dTAO).
How do I research Coldint / bootstrap before staking?
Read the mechanism above, open the official repo/docs when available, then verify pool depth, flows, and activity on SN29. Cross-check with the metrics checklist.
Is this financial advice?
No. TaoScale publishes educational explainers and live tools. Decisions to stake are yours alone.
Not financial advice. Educational overview of Coldint / bootstrap (SN29) compiled from public project materials and ecosystem documentation. Mechanisms and market structure change, so verify live data and official sources before acting.
