# **What is Polkadot?**
Polkadot is an open-source blockchain protocol designed to connect multiple blockchains, enabling interoperability, scalability, and shared security. It was founded in 2016 by Gavin Wood (co-founder of Ethereum), Robert Habermeier, and Peter Czaban, and its mainnet was launched in 2020.
#### **Key Features**:
1. **Interoperability**: Facilitates the transfer of data and assets between heterogeneous blockchains (public, private, oracles) using standards like XCM.
2. **Multi-chain Architecture**:
- **Relay Chain**: The core that coordinates consensus and security.
- **Parachains**: Independent chains with their own tokens and rules.
- **Bridges**: Connect Polkadot with external networks like Ethereum.
3. **Decentralized Governance**: DOT holders vote on updates and policies, avoiding forks.
#### **DOT Token**:
- **Functions**: Staking (security), governance, and bonding to add parachains.
