Module 2: Blockchain for Decentralized Connectivity

Goal: Enable transparent, incentivized Wi-Fi sharing and governance.

2.1 Immutable Ledger

• Function: Record network usage, bandwidth contributions, and transactions.

• Implementation:

  • Structure: Lightweight blockchain optimized for high-frequency microtransactions.

  • Data: Hashes of bandwidth usage logs, user contributions, and payment records.

  • Syncing: Supports offline logging with online reconciliation.

• Privacy: Stores only hashed metadata, protecting user identities.

• Example: A café shares 100GB of bandwidth; its contribution is logged for rewards.

2.2 Smart Contracts

• Function: Automate bandwidth sharing, payments, and network policies.

• Implementation:

  • Logic: Solidity-based contracts match bandwidth providers with users, settle payments, and enforce SLAs (e.g., 99% uptime).

  • Execution: Triggered by AI-verified contributions (e.g., 1GB shared).

• Privacy: Restricts access to authorized parties via cryptographic keys.

• Example: A smart contract pays a user 10 WIFI tokens for sharing 50GB of Wi-Fi.

2.3 Decentralized Identity (DID)

• Function: Secure, anonymous authentication for network participants.

• Implementation: W3C DID standard, with identities verified on-chain.

• Privacy: Enables pseudonymous access to shared networks.

• Example: A traveler connects to a WifiAI hotspot anonymously via DID.
