Overview

Zus (Züs Network) is a decentralized, zero-knowledge storage network offering S3-compatible storage with no egress or API fees, targeting privacy-conscious users and developers. It operates on a market-driven pricing model with independent blobbers. While technically ambitious and under active development, the project raises concerns: its flagship app domain lapsed in August 2026, the ZCN token has collapsed by ~99.97%, and there is no verifiable public pricing.

What you can rent

You can rent decentralized storage capacity on the Züs Network, which uses erasure coding and zero-knowledge encryption across independent blobbers. The network supports ACID-compliant, S3-compatible access via ZS3. Contracts are typically fixed-term (often one year) with flexible options, but you do not own the hardware or control the blobbers directly. You get storage access and claimed durability, but not self-custody or open-source client guarantees.

Contract & terms

Contracts are typically prepaid for a storage duration of one year, classified as fixed-term or flexible, though the exact contract_term_days is not specified. There is no published maintenance fee. The SLA promises 99.9% uptime with service credits for misses, but no refund policy is documented for prepaid allocations. Payout terms and thresholds are irrelevant as this is a storage service, not a mining or compute rental.

Proof & verifiability

Züs documents protocol-level proof mechanisms like storage challenges, chain hashing, and proxy re-encryption, and uses erasure coding across blobbers. However, there is no independent durability attestation or published durability nines. The proof level is partial: while the architecture is transparent, there is no third-party verification of actual data persistence or recovery rates.

Reliability & history

Züs has a documented corporate entity (0Chain Corp. in the U.S.) and active GitHub development as of 2026-09-24. However, the flagship consumer app vult.network stopped resolving in August 2026, and the ZCN token is down ~99.97% from its 2021 high. Community discussion is sparse and mostly operator-driven. Despite ongoing code commits, the app outage and token collapse signal serious reliability concerns.

Pricing

There is no fixed public price per TB; storage costs are determined by blobber competition using an equilibrium formula, with write costs prepaid for the storage term (typically one year). Reads are often free. The site claims "2x lower costs" than AWS due to zero egress and API fees, but provides no numeric rate. Payment is possible via credit card through the Vult app subscription or in ZCN token, but KYC requirements are unknown.

Verdict

Züs is a technically innovative project with active development, but the lapse of its main app domain, the near-total collapse of its token, and lack of verifiable pricing or durability proof make it too risky for critical data. Proceed only with small, non-essential trials if you understand the experimental nature and potential for data loss.

// Zus (Zus Network) FAQ

Is Zus (Zus Network) legit?

Based on our checks as of 2026-09-24: Zus (Zus Network) scores 5.5/10 in our weighted review. We logged 3 red flags (listed above). Current status: watch - A genuinely decentralised zero-knowledge storage network that is still under active development, but with no verifiable price, a flagship consumer app whose domain lapsed in August 2026 and a token down 99.97% from its high, it is a watch-list project rather than a safe place for data you need to retrieve. User reports and operator background are documented with dated sources in the meta-review below.

What do I actually get when I rent storage on Züs?

You get encrypted, decentralized storage via an S3-compatible interface, managed by independent blobbers. You do not get hardware ownership, self-custody, or guaranteed data recovery, and the service depends on the network’s operational continuity.

What are the total costs and fees involved?

The write cost is prepaid for the storage duration (typically one year), with no listed $/TB price. Reads are often free. There is no maintenance fee, but no published breakdown of total cost; blobber pricing is market-driven and not transparent.

Is there a minimum purchase or trial option?

Minimum purchase details are not published. While the Vult app allowed card payments for subscriptions, its domain is now offline, so trial access or small purchases cannot be verified as currently available.

How do payouts or service credits work?

Payouts do not apply - this is a storage service, not an earning platform. For SLA breaches, service credits are issued: 10% for 99.0-99.9% uptime, 25% for 95.0-99.0%, and 100% for below 95.0%, claimed within 30 business days.

What happens if Züs shuts down?

If the network or operator shuts down, your data may become inaccessible. Prepaid allocations offer no refund guarantee, and recovery depends on blobber availability - there is no documented exit or migration plan.

How does Züs compare to buying storage directly or using AWS?

Züs promises lower costs via no egress/API fees and decentralization, but lacks price transparency and proven reliability. Unlike AWS, it offers no clear support or SLA enforcement path, and compared to self-hosting, it provides convenience but no self-custody.
