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.

NotesAISync features and specs

  • Notion Integration
    The tool appears to integrate directly with Notion, allowing users to sync notes and AI-generated content seamlessly into their existing Notion workspace without needing to switch platforms.
  • AI-Powered Features
    As an AI-based note tool, it likely offers features such as automated summarization, organization, or content generation, which can save time compared to manual note-taking and organization.
  • Centralized Note Management
    By syncing AI notes into Notion, users can maintain a single source of truth for their information, avoiding the need to manage multiple disconnected apps.
  • Potential Productivity Boost
    Automating note syncing and organization could streamline workflows for professionals, students, or teams who rely heavily on Notion for project management and documentation.
  • Niche Specialization
    Being focused specifically on Notion syncing suggests the product may be highly optimized for users who already use Notion as their primary knowledge management tool, rather than being a generic note app.

Possible disadvantages of NotesAISync

  • Limited Information Available
    Details about the specific features, pricing, and reliability of NotesAISync are not widely documented, making it difficult to verify its full capabilities or reputation.
  • Dependency on Notion
    Since the tool is built around Notion integration, users who don't already use Notion may find little value in this product, limiting its overall usability.
  • Potential Sync Reliability Issues
    Third-party sync tools often face challenges with API rate limits, sync delays, or data conflicts, which could affect the consistency of notes between the AI tool and Notion.
  • Privacy and Data Security Concerns
    Using an AI-powered third-party tool that syncs with personal or business notes raises potential concerns about how sensitive data is stored, processed, and protected.
  • Unclear Pricing or Support Structure
    Without clear public information on subscription costs, customer support quality, or update frequency, users may face uncertainty about long-term reliability and value for money.

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 NotesAISync

Overall verdict

  • I don't have verified information about NotesAISync at notion.ainotevault.com. This does not appear to be a widely recognized or documented product, and I cannot confirm its features, reliability, security practices, or user satisfaction. I'd recommend independently verifying its legitimacyโ€”checking for company transparency, reviews on trusted platforms, security certifications, and data privacy policiesโ€”before using it, especially since it seems to involve syncing with Notion, which means handling potentially sensitive personal or organizational data.

Why this product is good

  • No independent reviews or reputable sources could be found to confirm claims about this product
  • Unclear company่ƒŒๆ™ฏ, ownership, or business track record
  • No verifiable information about data security or privacy practices
  • Domain name structure suggests it may be a small, unverified, or new service

Recommended for

  • Not recommended until independent verification of legitimacy, security, and reviews can be completed
  • Users should exercise caution before granting access to Notion data or personal information
  • If considering trying it, do so only with non-sensitive test data and check for red flags like poor documentation, lack of contact information, or absence of a privacy policy

Questions & Answers

As answered by people managing Shardnet.app and NotesAISync.

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)
