Nexion - For Windows & Open Source

Product Introduction

1. Nexion is a Web3-native SSH management solution that replaces traditional SSH key authentication with blockchain-based wallet credentials. It provides native Windows support alongside macOS and Linux compatibility, leveraging Electron for cross-platform functionality while being fully open-source under the MIT License. The product stores encrypted SSH configurations on X Layer blockchain, combining decentralized storage with military-grade encryption protocols.
2. The core value lies in eliminating SSH key management complexity through Web3 wallet integration, enabling unified authentication across servers while ensuring configs remain securely stored on-chain. By utilizing blockchain’s immutability and smart contracts, it solves data loss risks and enables granular team permissions at a predictable low cost ($1.20/year for on-chain storage).

Main Features

1. Web3 Authentication: Replaces SSH keys with crypto wallet logins (OKX, MetaMask, Trust Wallet) via WalletConnect, using ECIES encryption for identity verification. This enables one-click authorization/revocation across all servers without manual key distribution. Authentication events are recorded on-chain for auditable trails.
2. Blockchain-Backed Storage: SSH configurations are encrypted using ECIES + ChaCha20Poly1305 algorithms and stored on X Layer blockchain, ensuring tamper-proof persistence with 24/7 global access. Configurations sync automatically across devices upon wallet connection, eliminating manual backups.
3. Quantum-Resistant Security: Implements hybrid encryption combining ECIES (Elliptic Curve Integrated Encryption Scheme) for key exchange and ChaCha20Poly1305 for data encryption, designed to resist both classical and quantum computing attacks. All operations are recorded as on-chain events for compliance auditing.

Problems Solved

1. Eliminates SSH Key Proliferation: Solves the pain point of managing multiple SSH keys across teams by using wallet-based authentication, reducing human error and revocation complexity. Traditional key rotation processes are replaced with smart contract-driven permissions.
2. Targets Developers/DevOps Teams: Specifically designed for developers managing server fleets or distributed teams requiring secure, auditable access. Ideal for Web3-native organizations needing blockchain-integrated infrastructure tools.
3. Cross-Device Configuration Sync: Addresses the chaos of manual SSH config backups by storing encrypted settings on-chain, allowing instant access from any device via wallet authentication. Use cases include disaster recovery scenarios and multi-machine development environments.

Unique Advantages

1. Blockchain-Driven Workflow: Unlike tools like SecureCRT or OpenSSH, Nexion decentralizes storage and access control via X Layer blockchain, ensuring configs are owned exclusively by wallet holders rather than third-party platforms.
2. Smart Contract Permissions: Innovates team management by encoding access policies in deployable contracts (e.g., time-bound access, IP whitelisting), enabling automated compliance without centralized servers.
3. Cost-Efficient Architecture: Leverages X Layer’s low gas fees ($1.20/year per config) compared to Ethereum-based solutions, while providing native Windows support absent in most open-source SSH tools. The MIT-licensed codebase allows enterprise customization without vendor lock-in.

Frequently Asked Questions (FAQ)

1. Which wallets are supported for authentication? Nexion supports WalletConnect-compatible wallets including OKX Wallet, MetaMask, and Trust Wallet. Hardware wallets like Ledger can be used via these interfaces for enhanced security.
2. How does on-chain storage affect performance? Configurations are encrypted client-side before being stored as micro-transactions on X Layer, optimized for sub-3-second confirmation times. Daily usage doesn’t require blockchain interaction after initial setup.
3. Can I use Nexion without coding skills? Yes, the Electron-based GUI provides point-and-click configuration, while advanced users can directly edit JSON-based profiles or deploy custom smart contracts for team rules.
4. Is there a self-hosted blockchain option? While optimized for X Layer, the open-source code allows modification to support private chains or alternative L2 networks like Arbitrum for enterprise deployments.
5. How does quantum resistance work in practice? ECIES uses secp256k1 curves (quantum-vulnerable) for wallet compatibility but pairs them with ChaCha20Poly1305 symmetric encryption, which is quantum-safe. Future versions will integrate post-quantum algorithms like Kyber-1024.
