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.

Possible disadvantages of StackrApp

  • Limited Popularity and Community Size
    StackrApp has a relatively small user base compared to more established platforms, which limits the breadth of community content and shared stacks available for discovery.
  • Limited Integrations
    The platform may lack deep integrations with other popular developer tools, project management systems, or IDEs, reducing its utility within existing workflows.
  • Sparse Documentation and Resources
    As a smaller platform, StackrApp may have limited documentation, tutorials, or support resources, making it harder for new users to get the most out of the tool.
  • Uncertain Long-term Viability
    Being a lesser-known product, there may be concerns about its long-term maintenance, updates, and whether the platform will continue to be supported in the future.
  • Limited Advanced Features
    The platform may lack more advanced features such as detailed analytics, team management capabilities, or robust comparison tools that power users and larger organizations might need.

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.

Analysis of StackrApp

Overall verdict

  • I don't have verified, up-to-date information about StackrApp (stackrapp.com) to make a reliable assessment. I'm not able to confirm this product's features, reputation, or quality with confidence, and I don't want to provide potentially inaccurate information about a specific commercial service.

Why this product is good

  • I lack verified data on this specific product's actual performance and user reviews
  • Providing fabricated details about features or quality would be misleading
  • Product offerings and quality can change over time, making unverified claims risky
  • I cannot browse the internet in real-time to check the current state of this website or app

Recommended for

  • Anyone considering this app should check recent user reviews on independent platforms like Trustpilot, G2, or app stores
  • Research the company's reputation through the Better Business Bureau or similar consumer protection resources
  • Look for recent, dated articles or reviews rather than relying on AI-generated assessments for specific commercial products
  • Try a free trial or demo if available before committing, and verify claims directly with the company

Questions & Answers

As answered by people managing Shardnet.app and StackrApp.

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?

Shardnet.app's answer

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)
