No analysis of Code for Fun yet.

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 Code for Fun and Shardnet.app.

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