Hippius is Bittensor subnet 75 (SN75), a project in the Storage and Data Availability lane. Decentralized cloud storage on TAO
Hippius (SN75) is trying to be the Bittensor-native answer to AWS S3, decentralized cloud storage where files split into 30 encrypted shards across independent miners, billed in TAO instead of bandwidth fees.

What is Hippius (SN75)?
Hippius is a decentralized storage and compute network. Users upload files through an S3-compatible API, and the network splits each file into encrypted shards that are distributed across miners running storage nodes.
In plain English: It is like Dropbox or AWS S3, but the files live across hundreds of independent operators rather than one company's data centers.

How miners and validators work
Like every Bittensor subnet, SN75 is a two-sided market: miners produce work, validators score it, and emissions follow those weights under the network’s dTAO economics.
- Miners run storage nodes that host user files in buckets, each assigned a unique IP, and earn rewards for storage capacity and bandwidth served
- Validators assign IP addresses to participants, track bucket sizes, verify storage requests and file ownership, and manage the credit and referral systems
Mechanism and design
According to the TAO.app about page, miners operate storage nodes that host user files in buckets and earn rewards for the capacity and bandwidth they provide. Validators assign IP addresses to participants, track bucket sizes and user bandwidth, verify storage requests and file ownership, and run a credit-batch system that allocates rewards. The S3-compatible API surface lets existing tools point at Hippius with minimal code changes, and social posts describe a 30-shard sharding scheme with encrypted distribution across independent miners. Details below the API are not fully documented in the main repo README, so treat the shard count and durability properties as claims from the team rather than from inspected code.
The repository at thenervelab/thebrain is the active codebase: 245 total commits, 6 contributors visible on the live GitHub API, last commit on 2026-05-08, written in Rust. Recent commit messages reference a marketplace pallet, compute subscriptions, credit pallet refinements, and referral reward distribution, consistent with the network feature set described on the about page. Two of the past month's announcements in the Bittensor community covered Arion miner releases at versions 0.1.20 and 0.1.21, focused on P2P connectivity and historical synchronization.
A note on emissions: Hippius is currently at 0% emission share. Under Taoflow, this happens when net staking flows over the trailing window are slightly negative, and Hippius shows net flows of about -31 TAO over the past 7 days. Emission share can return as soon as net flows turn positive again. Separately, the subnet is configured with a 98.77% miner burn ratio, meaning when emissions do flow, almost all miner-side emissions are burned rather than paid to miners. That choice is the subnet owner's, and is most commonly used to recover registration cost or fund operational subsidies.
Why the project exists
- The problem it solves: Cloud storage is dominated by a handful of US providers that meter bandwidth aggressively, charge punitive egress fees, and reserve the right to deplatform accounts.
- The opportunity: Storage is one of the few decentralized use cases with a clean dollar comparison. If Hippius can match S3 on durability while undercutting it on egress, the value proposition is obvious to anyone running a backup target, a static asset host, or an AI workflow that needs persistent state.
- The Bittensor advantage: Incentivized storage networks have existed for years through Filecoin, Storj, and Sia, but Bittensor lets the network pay miners through TAO emissions rather than user fees alone, which can compress prices below what fee-only networks can sustain.
- Traction signals: Social posts in the past month cite roughly 100 TB of egress served and 162 active miners on chain. Recent academic R&D and healthcare-data pilots are mentioned by Hippius community channels, though specifics are not publicly verifiable.
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
- Zero emission share: With net flows slightly negative over the trailing window, the subnet is currently receiving 0% of network emissions. This is a Taoflow consequence, not a permanent state, but it does mean miners are operating without protocol-level reward right now.
- High miner burn configuration: At 98.77%, almost all miner emissions are routed to burn rather than to miners. Combined with current 0% emission share, miner economics depend almost entirely on real user payments. Whether organic storage revenue is enough to sustain 162 miners long-term is an open question.
- Competition: Decentralized storage is a crowded category. Filecoin, Storj, Sia, and Arweave have multi-year head starts, deeper enterprise integrations, and in some cases lower retrieval latency. Hippius needs to win on price, censorship resistance, or developer experience rather than novelty.
- Concentration: Stake distribution shows a Gini coefficient of 0.68 with a Nakamoto coefficient of 17, in the middle of the pack for subnets of this size.
How this fits a TAO portfolio
Many holders keep a root vs subnet split: root for calmer TAO exposure, subnets like Hippius for thematic upside (and higher variance). If you use TaoScale, you can size SN75 from your wallet without handing over custody. See non-custodial staking.

FAQ
What does Hippius do on Bittensor?
It is like Dropbox or AWS S3, but the files live across hundreds of independent operators rather than one company's data centers.
What is the SN75 alpha token?
When you stake TAO into subnet 75, you receive that subnet’s alpha. Its price versus TAO moves with the subnet’s pool (see what is dTAO).
How do I research Hippius before staking?
Read the mechanism above, open the official repo/docs when available, then verify pool depth, flows, and activity on SN75. 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 Hippius (SN75) compiled from public project materials and ecosystem documentation. Mechanisms and market structure change, so verify live data and official sources before acting.
