Hippius Subnet 75, a Bittensor-powered decentralized cloud storage platform, has rolled out quantum-safe encryption across its network, fortifying user data against emerging quantum computing risks without disrupting operations. The upgrade, deployed this week, addresses vulnerabilities in traditional cryptography that could be exploited by quantum machines in the coming years.
Launched in March 2025 as Bittensor’s Subnet 75, Hippius positions itself as the “missing piece” for persistent, decentralized storage in the AI ecosystem.

Hippius combines IPFS-like content-addressed storage for public or static files with S3-compatible object storage for private or mutable data, enabling seamless integration for everyday users, developers, and enterprises. All data is encrypted end-to-end and anonymized, with user identities managed via cryptographic mnemonics rather than traditional accounts, emphasizing self-custody and transparency. The platform also plans to expand into virtual machines and confidential computing, aiming to serve as the “memory” layer for Bittensor’s decentralized AI network.
The new quantum-safe feature upgrades cryptographic keys and signatures to resist attacks from quantum computers, which could otherwise enable “harvest now, decrypt later” strategies—where adversaries store encrypted data today for decryption in 5-20 years. This is critical for blockchain-stored assets like smart contracts, research data, or customer records that demand long-term confidentiality. File contents continue using efficient, hardware-accelerated encryption, while a small “envelope” of metadata (in kilobytes) adds quantum-resistant protection.
Implementation ensures minimal impact: New uploads are quantum-safe by default, legacy files auto-upgrade without re-uploads, and workflows remain unchanged. Performance overhead is negligible, with no noticeable slowdowns reported, thanks to batched processing for large datasets.
The move by Hippius portrays growing concerns in crypto about quantum risks, as Bittensor subnets like Hippius handle increasing volumes of user data. With $TAO price currently picking up, Hippius’s upgrade sets a precedent for future-proofing decentralized infrastructure amid advancing quantum tech.
