An **on-chain social graph** is a decentralized representation of social connections and interactions recorded on a blockchain, providing users with:
1. **Decentralization**: Full control over their data and connections.
2. **Portability**: Easily transferable social graph across applications.
3. **Transparency**: Immutable and transparent interactions.
4. **Security**: Enhanced protection from tampering.
5. **Ownership**: Ability to monetize data and interactions.

**Airdropping tokens** on an on-chain social graph ensures:
- **Transparency** and **security** by recording transactions on the blockchain.
- **Fairness** through predefined criteria and verifiable interactions.
- **Decentralization** by reducing reliance on third parties and giving users control over their social data.
