What is Polkadot?

Polkadot is an innovative network that links different blockchains. The network of chains operates side-by-side on the relay chain, and they are able to transmit messages to each other. These chains are known as parachains which combine safety while being able to operate totally arbitrary state-transition functions. This helps them to be completely different, yet to be able to interact with each other. In other words, separate blockchains can exchange messages and transactions in governance, scalable, and interoperable framework without trust, that produces a fully decentralized dApps and tools ecosystem. Polkadot enables cross-blockchain transfers of any type of data or asset. It is a project founded by Dr.Gavin Wood, who is also a co-founder of Ethereum.

How does Polkadot work?

Polkadot network works with the help of three separate chains which allow it to solve issues of both interoperability and scalability

The Relay Chain

Ensures a relay chain, the so-called bedrock on which parachains can operate interoperable, instead of a single chain for all dApps.

The Parachain

Multiple parachains are hosted upon the relay chain. They function as complex data structures that are hosted side-by-side. Parachains are independent blockchains that accumulate and process their own transactions.

The Bridge Chain

Other blockchains can interact with Polkadot network via so-called bridge chains, that provide Polkadot network to be linked to the Bitcoin, Ethereum, and several other blockchains, wherein each blockchain maintains its consensus mechanisms and terms.
