## The Scalable, Multichain Network for Radical Innovation.

Unprecedented interoperability and scalability for blockchain developers who want to quickly push the limits of what’s possible. Built using Substrate with nearly the same codebase and industry-leading multichain infrastructure as Kusama’s cousin, Polkadot.

## Origin of Kusama

The relationship between society and technology has deteriorated to the point where large entities routinely stretch and overstep their authority.

Kusama is a network built as a risk-taking, fast-moving ‘canary in the coal mine’ for its cousin Polkadot. It's a living platform built for change agents to take back control, spark innovation and disrupt the status quo.

## What is Kusama?

Kusama is a scalable network of specialized blockchains built using Substrate and nearly the same codebase as Polkadot. The network is an experimental development environment for teams who want to move fast and innovate on Kusama, or prepare for deployment on Polkadot.

Kusama was founded in 2019 by Gavin Wood, founder of Polkadot and co-founder and former CTO of Ethereum.

## Bring
to your project

### Innovation

Kusama is built by the same teams as Polkadot, using nearly the same code and tools. The network places the latest tech from Parity Technologies and Web3 Foundation in the hands of developers, even before those features make it to Polkadot.

### Scalability

Kusama’s sharded blockchains and open governance provide a scalable and future-proof infrastructure for businesses, marketplaces and applications to deploy and mature.

### Interoperability

Kusama brings multiple blockchains together into one sharded network, freeing developers from the siloes created by legacy blockchain networks.

### Customization

With Substrate, developers can build their own app-specific blockchain and connect it to Kusama.

## Develop on the
Canary Network

Many teams will choose Kusama for their dapp or parachain and remain exclusively on Kusama. Other teams will join Kusama as a temporary preparation ground for deployment on Polkadot.
