What is Polkadot? How does it Work?

Polkadot can transfer this data across public, open, permissionless blockchains as well as private, permissioned blockchains.

This makes it possible to build applications that get permissioned data from a private blockchain and use it on a public blockchain. For instance, a school’s private, permissioned academic records chain could send a proof to a degree-verification smart contract on a public chain.

Connecting the dots

Parachains
Sovereign blockchains that can have their own tokens and optimize their functionality for specific use cases.

Parathreads
Similar to parachains but with a pay-as-you-go model. More economical for blockchains that don’t need continuous connectivity to the network.

Bridges
Allow parachains and parathreads to connect and communicate with external networks like Ethereum and Bitcoin.

Consensus Roles

Governance Roles

Technical Committee
Composed of teams actively building Polkadot. Can propose emergency referenda, together with the council, for fast-tracked voting and implementation.

Built with the best technology

Polkadot’s state machine is compiled to WebAssembly (Wasm), a super performant virtual environment. Wasm is developed by major companies, including Google, Apple, Microsoft, and Mozilla, that have created a large ecosystem of support for the standard.

Polkadot’s networking uses libp2p, a flexible cross-platform network framework for peer-to-peer applications.

Positioned to be the standard for future decentralized applications, libp2p handles the peer discovery and communication in the Polkadot ecosystem.

The Polkadot runtime environment is being coded in Rust, C++, and Golang, making Polkadot accessible to a wide range of developers.

Processing transactions in parallel

Interactions on parachains are processed in parallel, enabling highly scalable systems.

Transactions can be spread out across the chains, allowing many more transactions to be processed in the same period of time.

A better security model

Polkadot takes a different approach by letting blockchains pool their security, which means that the blockchains’ security is aggregated and applied to all.

By connecting to Polkadot, blockchain developers can secure their blockchain from day one.

Transparent on-chain governance

The relay chain uses a sophisticated governance mechanism that is designed to establish a transparent, accountable and binding process for resolving disputes and upgrading the network.

DOT tokens are used to participate in governance decisions, including tabling proposals, voting, and bonding.

Parachains are free to design their own governance mechanisms, allowing for maximum freedom without affecting other parachains.

GRANDPA: a trustworthy consensus algorithm

Under good network conditions, GRANDPA can finalize blocks nearly instantly. Under bad network conditions, like a network partition, GRANDPA can finalize large quantities of blocks (theoretically millions) at once when the partitions resolve.
