🔐 Encryption Model

Hybrid RSA + AES Encryption

CryptoMessenger.io uses a hybrid encryption model to ensure both performance and security:

  • RSA (Asymmetric Encryption) is used during the initial handshake between users to securely exchange a session key. Each user has a unique RSA public/private keypair stored in association with their blockchain wallet.

  • AES (Symmetric Encryption) is used to encrypt the actual message content. Once a session key is securely shared, all chat messages are encrypted with AES-256 for maximum speed and efficiency.

This ensures:

  • Messages cannot be decrypted by nodes, storage providers, or even the platform team.

  • Forward secrecy is supported via rotating session keys.

  • Identity is cryptographically tied to a blockchain-verified keypair.

🗂️ Decentralized Storage Layer

Peer-to-Peer Media Storage (IPFS or Similar)

To preserve message privacy and avoid centralized control, CryptoMessenger.io uses decentralized storage for file attachments (images, voice notes, documents, etc.):

  • Media files are encrypted with the same AES session key before upload.

  • Files are uploaded to a peer-to-peer storage network such as IPFS (InterPlanetary File System) or Arweave.

  • Only users with the appropriate decryption key can access the contents.

  • Message payloads (text) are stored in-memory or minimally cached, never permanently stored on centralized servers.

This ensures:

  • No central point of failure or censorship.

  • Media is globally accessible but securely encrypted.

💸 Smart Contract Integration

Reward Distribution via Smart Contracts

The CryptoMessenger ecosystem uses smart contracts to automate the distribution of token-based rewards and manage in-app economic functions:

  • User Rewards: Users can earn tokens for participating in the network (e.g. high engagement, verifying nodes, or inviting users).

  • Node Incentives: Decentralized relay or storage nodes can stake tokens and earn rewards for uptime and performance.

  • Tipping & Microtransactions: Users may send crypto tips in real time using an in-chat payment module.

  • Governance Contracts: Token holders can vote on platform proposals through DAO-style smart contracts.

All contracts are:

  • Deployed on a transparent, auditable blockchain (e.g. Ethereum, Arbitrum, or Solana).

  • Open source and verifiable.

  • Upgradeable via community governance (if enabled).
