KSM, also known as Kusama, is a cryptocurrency that was created as a sister network to Polkadot. It was designed to be a scalable and interoperable blockchain platform that allows developers to build decentralized applications (dApps) and connect them to other blockchain networks. Kusama is unique in that it allows developers to test their dApps in a real-world environment before deploying them on the Polkadot network. This helps to ensure that the dApps are secure and functional before they are released to the public.

Kusama has its own native token, also called KSM, which is used to pay for transaction fees and to participate in the network's governance. KSM holders can vote on proposals to change the network's parameters, such as the block size or the transaction fees. They can also propose their own changes to the network and receive rewards for doing so. Kusama's governance system is designed to be decentralized and community-driven, with the goal of ensuring that the network remains secure and adaptable to changing market conditions.
