Züs

Decentralized Storage Network

High-performance enterprise-grade decentralized cloud storage platform (formerly 0Chain) with a proprietary two-layer blockchain architecture separating consensus (Miners/Sharders) from storage (Blobbers). Features three-layer data security (fragmentation, proxy re-encryption, erasure coding), QoS-enforced storage agreements, and a ZCN token economy.

Decentralized Storage Network Atributos

Origins Enterprise cloud storage / data sovereignty
Database Custom two-layer blockchain (main chain for consensus + storage sidechain via Blobbers) with erasure coding
Query Language REST API; Züs SDK (Go, JavaScript)
Data Formats Any binary; JSON metadata
Mobile Support Mobile support (Vult app — iOS/Android)
Web Support Yes (Blimp web app; Chalk web app)
Native Apps Native apps (Vult, Blimp, Chimney, Chalk apps)
Terms Paid SaaS + Self-hosting (Blobber operators); ZCN token for storage payments
Funds $39M ICO (ended January 2018)
Based On Novel (proprietary two-layer blockchain; no external base protocol)
P2P Architecture Public Blockchain (DPoS-based two-layer chain; storage on Blobber sidechain)
Overlay Network Global
Content Addressing Yes (files addressed by Merkle hash across Blobbers)
Local-First N/A (cloud model)
E2EE Yes (proxy re-encryption for private sharing; data encrypted client-side)
Byzantine Fault Tolerance Yes (squared-staking DPoS consensus; Sybil resistance via randomized view change; Blobber slashing for non-performance)
Signature Ed25519
Permissions Cryptographic Capabilities (proxy re-encryption keys for sharing; write markers as cryptographic commitments)
Semantic Web Compatibility N/A
Smart Contract Yes (storage smart contracts on Züs blockchain; ZüsDAO governance)
Protocol Stack Position Application-layer (built on TCP/IP)
Asset / Value Embedding Native (ZCN token embedded in storage contracts; 'Store = Stake' model links storage to locked ZCN)
Protocol Maturity / Standardization Community Standard (production deployed; proprietary open standard; no formal standards body)
Update Policy Mutable (versioned) — files can be updated via new write markers; immutability available as configuration option
Storage Proof Mechanism Proof of Access (PoA challenges) — Miners issue random challenges to Blobbers; Blobbers must return correct data proofs; failure results in ZCN slashing from challenge pool
Economic / Incentive Model Token rewards (ZCN native token): clients lock ZCN for storage; Blobbers stake ZCN as collateral; reward pool distributed to Blobbers for proven storage; 'Store = Stake' model ties storage capacity to locked ZCN
Retrieval Guarantee Strong (QoS protocol enforces performance SLAs; cryptoeconomic slashing for non-performance; near wire-speed retrieval design goal)
