Decentralized Storage Network

Decentralized Durability Engine (DDE) and P2P storage protocol developed under the Logos technology stack (IFT/Status), designed for censorship-resistant, durable data storage using erasure coding, ZK-proof-based remote auditing, and a marketplace for incentivizing storage providers. Targets archival and cold storage use cases with 'lazy' data repair.

Dev Status 🔬 Beta

Dev Status Detail

Beta (non-incentivized testnet launched Sept 2024; incentivized testnet and mainnet planned)

Owner

IFT (formerly Logos/Status); Dmitriy Ryajov (CTO)

Country

Global / distributed team (IFT is decentralized)

Start Year 2021

Stack

Nim

Funding

Personal investment / Foundation (IFT/Logos internal funding; part of Status/IFT ecosystem)

Last Investigated Mar 9, 2026

Use Case Domains

Platform Evolution & Sovereignty

Affordances

Self-hostable

Local-first storage

Decentralized Storage Network Attributes

Origins

Censorship-resistant archival storage / Logos ecosystem infrastructure

Database

Distributed (erasure-coded blocks via DHT; content-addressed CIDs; nim-libp2p)

Query Language

REST API

Data Formats

Any binary; CID-addressed content blocks

Mobile Support

N/A (infrastructure protocol)

Web Support

Planned (API-accessible; no web UI yet)

Native Apps

N/A (CLI node; no GUI yet)

Terms

Self-hosting (run node); CDX token (planned for mainnet marketplace)

Funds

Undisclosed (funded internally by IFT; no public fundraise disclosed)

Based On

IPFS-influenced (uses CIDs, DHT, libp2p); custom erasure coding and ZK proof layer

P2P Architecture

DHT (Kademlia-based via nim-libp2p; block exchange protocol similar to BitSwap)

Overlay Network

Global

Content Addressing

Yes (IPFS-compatible CIDs)

Local-First

N/A (distributed storage)

E2EE

Yes (planned; privacy-preserving design goal of Logos stack)

Byzantine Fault Tolerance

Planned (ZK proof-based remote auditing for storage verification; marketplace with slashing)

Signature

Ed25519 / ECDSA (libp2p standard); ZK-SNARKs (Poseidon2 hash for storage proofs)

Permissions

N/A (currently open; marketplace-based permissions planned)

Semantic Web Compatibility

N/A

Smart Contract

Planned for future (Codex Marketplace contracts for storage agreements and payments)

Protocol Stack Position

Application-layer (built on TCP/IP)

Asset / Value Embedding

Application-layer add-on (CDX token planned for marketplace; not yet deployed)

Protocol Maturity / Standardization

Pre-specification / Academic-Research (whitepaper published; testnet live; mainnet not yet launched; no standards body involvement)

Update Policy

Immutable / Append-only (content-addressed blocks are immutable; appendable data planned as future feature)

Storage Proof Mechanism

Hybrid: Erasure coding with ZK-SNARK audit (compact proofs of storage using SNARK circuits with Poseidon2 hashing; lightweight remote auditing without downloading data; slot recovery mechanism for 'lazy' repair)

Economic / Incentive Model

Token rewards (CDX token planned): storage providers stake CDX as collateral; clients pay CDX for storage marketplace slots; validators earn CDX for processing challenges

Retrieval Guarantee

Best-effort (incentivized via marketplace contracts; cryptographic proofs verify storage; lazy repair mechanism restores lost shards; mainnet guarantees not yet established)
