Polkadot

Polkadot is a blockchain network enabling interoperability between multiple specialized blockchains.

Polkadot is a multi-chain blockchain network that enables interoperability between independent blockchains using shared security, on-chain governance and parachains.

A "Layer 0" protocol that enables different blockchains to transfer messages and value in a trust-free fashion. It uses a central "Relay Chain" to provide security to several "Parachains" that plug into it, solving the problem of blockchain isolation.

Interoperability Governance: Used to secure the central Relay Chain and for "Parachain" auctions, allowing multiple specialized blockchains to communicate and share data securely.

Relay Chain Governance: Used for "Slot Auctions" where projects lock up tokens for years to win a spot on the network (Parachains). It is also used for staking and governance of the interoperability layer connecting different blockchains.
