Interoperability between blockchains

Polkadot

Polkadot (DOT) is a blockchain platform built to connect multiple blockchains—called parachains—allowing them to run in parallel yet share security, communicate, and scale together. DOT is used for staking, governance, and buying parachain slots. It underpins a multilingual Web3 where blockchains talk to each other securely and efficiently.

Founders: Robert Habermeier, Gavin Wood, Peter Czaban, and the Web3 Foundation

Technology & Use Case

Polkadot relies on a Relay Chain, which secures all connected parachains (application-specific blockchains). Parachains run transactions independently but benefit from shared, pooled security and interoperability enabled by the Relay Chain. Each parachain has its own governance, fees, and rules while still communicating with other parachains securely via the Relay Chain.

In this example the Yellow Blockchain (aka Parachain) is interacting with and using features from the Green Blockchain (aka Parachain). All operations are conducted within Polkadot's secure environment.

Origins & Team

Polkadot was conceived in 2016 by Gavin Wood (Ethereum co-founder and Web3 pioneer), along with Robert Habermeier and Peter Czaban under the Web3 Foundation, with core development by Parity Technologies. The platform launched in 2020 and has since become a foundational piece for interoperable Web3 applications.

Ecosystem & Partnerships

DOT holders guide the network through on-chain governance and use DOT for staking and core operations. Polkadot connects blockchains with bridges and lets parachains run either on-demand or permanently—providing scalability, parallel processing, and shared security across the ecosystem.
