Nexion

Product Introduction

1. Nexion is a decentralized SSH management solution that replaces traditional SSH keys with crypto wallet authentication and stores configurations securely on the X Layer blockchain. It integrates Web3 identity management with end-to-end encryption to streamline server access and configuration synchronization across devices. The product leverages blockchain technology to ensure data permanence, user control, and transparent cost structures.
2. The core value of Nexion lies in its ability to eliminate SSH key management complexity while reducing operational costs by up to 95% through blockchain automation. It provides a unified, auditable framework for server access, combining military-grade encryption with decentralized storage to address modern security and collaboration challenges.

Main Features

1. Web3 Authentication: Nexion uses crypto wallets like OKX, MetaMask, and Trust Wallet as SSH identities, enabling one-click authorization and revocation. This replaces fragmented SSH key sets with a single wallet-based authentication flow compatible with WalletConnect protocols.
2. On-Chain Encrypted Storage: SSH configurations are encrypted using ECIES and ChaCha20Poly1305 algorithms before being stored on the X Layer blockchain. Each configuration costs $1.20 annually, with gas fees averaging $0.01 per transaction, ensuring data permanence and global accessibility.
3. Military-Grade Encryption: Configurations and connection data are secured with quantum-resistant ECIES (Elliptic Curve Integrated Encryption Scheme) and ChaCha20Poly1305, providing forward secrecy and protection against brute-force attacks.
4. Cross-Platform Client: Built on Electron, Nexion supports Windows, macOS, and Linux with a native app experience. Users configure SSH parameters once and deploy them across all devices via blockchain-synced profiles.
5. Multi-Device Sync: Configurations stored on-chain are accessible from any device by connecting the crypto wallet, enabling seamless switching between workstations without manual backups or file transfers.
6. Smart Contract-Based Teams: Team permissions are managed through auditable smart contracts, allowing granular access control (read/write/admin) and secure configuration sharing. All operations generate on-chain audit trails for compliance.

Problems Solved

1. Pain Points Addressed: Traditional SSH key management requires manual rotation, error-prone cross-device synchronization, and insecure plaintext storage. Nexion automates these processes via blockchain while enforcing zero-trust encryption and permission models.
2. Target Users: Developers, DevOps engineers, and sysadmins managing multi-server environments; Web3-native teams requiring secure, auditable infrastructure access; organizations seeking to reduce SSH-related operational costs.
3. Use Cases: Securely onboarding remote team members via wallet-based authentication, recovering server access after device loss through blockchain backups, and auditing SSH access history via immutable on-chain records.

Unique Advantages

1. Differentiation: Unlike legacy SSH tools, Nexion decentralizes configuration storage and access control, removing reliance on centralized servers or subscription-based SaaS platforms.
2. Innovation: Combines ECIES for asymmetric encryption with ChaCha20Poly1305 for symmetric data protection, a hybrid approach optimized for blockchain storage costs and quantum resistance.
3. Competitive Edge: Transparent OKB-based pricing (e.g., $0.95 per configuration update) eliminates hidden fees, while X Layer’s low gas fees (~$0.01) make blockchain operations economically viable for everyday use.

Frequently Asked Questions (FAQ)

1. Which crypto wallets are supported? Nexion supports OKX Wallet, MetaMask, Trust Wallet, and any WalletConnect-compatible wallets, with future plans to add Ledger and Trezor integrations.
2. How is data security ensured on-chain? Configurations are encrypted locally using ECIES before blockchain storage, meaning even if the blockchain is compromised, data remains inaccessible without the user’s private key.
3. When will Windows/Linux versions launch? The macOS client is available now; Windows and Linux builds are in active development and will be released via GitHub by Q3 2024.
4. What if OKB’s price fluctuates? Gas fees are pegged to OKB but calculated in USD equivalents—for example, 0.005 OKB for configuration updates equals $0.95 when OKB is $190. Real-time OKB/USD rates are displayed in-app.
5. Can enterprises customize team permissions? Yes, organizations can deploy custom smart contracts to enforce role-based access policies (RBAC) or integrate with existing SIEM systems via blockchain event logs.
