title: "SHARDNET: A Serverless, Peer-to-Peer Protocol for Encrypted Data Exchange and Resilient Storage" author: "Shardnet Project" date: "2026-06-23" subject: "Shardnet Protocol"

keywords: [P2P, DHT, Kademlia, Reed-Solomon, AES-256-GCM, QUIC, encrypted storage, distributed systems]

Introduction

Shardnet is an application-layer peer-to-peer (P2P) protocol for secure, serverless data storage and exchange. Every file is encrypted client-side with AES-256-GCM, split into fifteen Reed-Solomon fragments, and distributed across the network. Any ten fragments are sufficient to reconstruct the original. Nodes communicate directly over QUIC/TLS 1.3 using a Kademlia-based DHT for discovery and routing. No central server holds data, credentials, or routing state. This document is the authoritative technical specification of the Shardnet protocol: transport, erasure coding, cryptography, identity, storage, and network maintenance.

Codeown.space features and specs

  • Code Ownership Tracking
    Codeown.space provides a dedicated platform for tracking and managing code ownership across repositories, helping teams clearly define who is responsible for which parts of the codebase.
  • Team Collaboration
    The platform facilitates better team collaboration by making it transparent who owns and maintains specific code areas, reducing confusion and improving communication among developers.
  • Simplified CODEOWNERS Management
    It offers a more user-friendly interface for managing CODEOWNERS files compared to manually editing them in repositories, making it easier to set up and maintain ownership rules.
  • Visibility and Accountability
    By clearly mapping code ownership, the tool increases accountability and helps ensure that code reviews and maintenance tasks are directed to the right people.
  • Integration with Git Workflows
    Codeown.space is designed to work with existing Git-based workflows and repositories, allowing teams to adopt it without drastically changing their development processes.

Possible disadvantages of Codeown.space

  • Limited Public Awareness
    Codeown.space is a relatively niche tool with limited public awareness and community adoption, which means fewer community resources, reviews, and third-party integrations are available.
  • Dependency on External Service
    Relying on an external platform for code ownership management introduces a dependency that could be problematic if the service experiences downtime or is discontinued.
  • Potential Learning Curve
    Teams already comfortable with manually managing CODEOWNERS files may find it unnecessary to adopt a new tool, and onboarding the team to a new platform adds overhead.
  • Limited Feature Documentation
    As a smaller platform, detailed documentation and tutorials may be sparse, making it harder for new users to fully understand and leverage all available features.
  • Pricing Uncertainty
    For teams evaluating the tool, the pricing model and long-term costs may not be immediately clear, making it difficult to assess the value proposition compared to free alternatives like native CODEOWNERS files.

Analysis of Shardnet.app

Overall verdict

  • Shardnet.app does not appear to be a widely recognized or established product/service, so there is insufficient verified information to confidently endorse it as good. Prospective users should independently research its reputation, security, and reviews before committing.

Why this product is good

  • Limited publicly available information or reviews to verify claims of quality or reliability.
  • No widely recognized track record, certifications, or third-party audits found.
  • Unclear business model or company transparency behind the domain.
  • Potential risk since lesser-known platforms may lack robust customer support or security measures.

Recommended for

  • Users willing to conduct thorough due diligence before trusting a lesser-known platform.
  • Early adopters interested in experimental or niche blockchain/network services.
  • Not recommended for users seeking well-established, heavily vetted solutions for critical or financial use cases.

Questions & Answers

As answered by people managing Shardnet.app and Codeown.space.

How would you describe the primary audience of your product?

Shardnet.app's answer

Technically-minded users and developers who want to store or share files without trusting a third party. This includes privacy-conscious individuals, open-source communities self-hosting shared documents, developers building decentralised applications that need a storage layer, and organisations that cannot or will not rely on cloud providers for sensitive data.

Who are some of the biggest customers of your product?

Shardnet.app's answer

Shardnet is currently in public alpha โ€” functionally complete but not yet independently audited for security. Early adopters are individual developers and privacy researchers evaluating the protocol. We're not listing customers until the security audit is done and the protocol is production-ready. If you're interested in an early deployment, reach out directly.

What makes your product unique?

Shardnet.app's answer

Shardnet removes the server from the equation entirely. Files are encrypted on your device (AES-256-GCM) before leaving it, split into 15 fragments via Reed-Solomon erasure coding, then spread across the peer swarm. Any 10 of those 15 fragments reconstruct the original โ€” even if a third of the network goes offline. Nodes storing your shards see only ciphertext indistinguishable from random noise. No account, no API key, no company holding your data. The decryption key travels only in your magnet link.

Why should a person choose your product over its competitors?

Shardnet.app's answer

Most "decentralised" storage products still have a centralised component โ€” a coordination server, a token smart contract, a wallet requirement, or a proprietary daemon. Shardnet has none of these. It runs as a single static binary with no runtime dependencies, connects over QUIC/TLS 1.3, and routes via a Kademlia DHT. There are no tokens, no fees, and no registration. If you run a node, you contribute storage and gain access to the swarm โ€” the protocol is self-sustaining because every user is also a provider.

What's the story behind your product?

Shardnet.app's answer

Shardnet started from a simple frustration: every "serverless" storage tool we looked at still had a server somewhere โ€” a coordinator, an incentive layer, or a hosted gateway. We wanted something where the threat model was actually clean: zero-knowledge storage, no central point of seizure, no account to compromise. We built the protocol in Rust, wrote the spec first, then implemented it โ€” QUIC transport, Kademlia DHT, Reed-Solomon erasure coding, AES-256-GCM encryption, all from scratch. The result is a single binary you can run on any Linux machine and be part of a global swarm in under ten seconds.

Which are the primary technologies used for building your product?

Which are the primary technologies used for building Shardnet?

Rust โ€” the entire stack, compiled to a dependency-free static binary QUIC / TLS 1.3 (quinn + rustls) โ€” encrypted transport with mutual Ed25519 authentication Kademlia DHT โ€” XOR-metric peer discovery and shard routing (K=20) Reed-Solomon erasure coding โ€” 10 data + 5 parity shards per file AES-256-GCM โ€” client-side file encryption Ed25519 โ€” node identity and signed chat messages Axum โ€” embedded HTTP/WebSocket server for the web GUI Argon2id โ€” proof-of-work for node admission (Sybil resistance)
