Polkadot is a heterogeneous multi-chain protocol that enables cross-blockchain transfers of any type of data or asset, not just tokens. Founded by Ethereum co-founder Gavin Wood, Polkadot uses a relay chain architecture that connects multiple specialized blockchains called parachains into a unified network. The platform features shared security across all connected chains, on-chain governance allowing token holders to vote on protocol upgrades, and forkless runtime upgrades. Polkadot's Substrate framework allows developers to build custom blockchains optimized for specific use cases, while XCM (Cross-Consensus Messaging) enables seamless communication between parachains. The ecosystem includes over 50 active parachains spanning DeFi, identity, gaming, IoT, and more. Polkadot 2.0 introduces agile coretime allocation, making blockspace more flexible and accessible.

Crypto DAOs

Polkadot features sophisticated on-chain governance through OpenGov, where DOT holders can propose, vote on, and implement protocol changes through a decentralized decision-making process.

Crypto Staking

Polkadot uses Nominated Proof of Stake where DOT holders can nominate validators or run validator nodes themselves to secure the network and earn staking rewards.

Developer Tools

Polkadot provides the Substrate framework for building custom blockchains, along with comprehensive SDKs, documentation, and developer resources for parachain development.

L1 Blockchains

Polkadot is a Layer 0/Layer 1 multi-chain protocol that connects specialized blockchains (parachains) through a shared relay chain, enabling interoperability and shared security across the entire network.
