Kusama, often referred to as "Polkadot's wild cousin," is an experimental blockchain platform that aims to provide a scalable and interoperable framework for developers. Built on Substrate, a blockchain building kit developed by Parity Technologies, Kusama shares a similar codebase with Polkadot, another interoperable blockchain. Kusama is designed to serve as a testbed for developers looking to innovate and deploy their own blockchain. It can also be used as a preparatory network before launching on Polkadot, although many projects choose to remain on Kusama for their final product. Kusama is designed to have a low barrier to entry for deploying parachains and is commonly used by early-stage startups and for experimentation.

Kusama operates on a multichain, heterogeneously-sharded design that uses a nominated proof-of-stake (NPoS) consensus system. This system allows it to perform rapid on-chain upgrades without a fork and support cross-chain message passing (XCMP) for communication with other parachains on the Kusama network. Kusama also features on-chain governance capabilities, which are decentralized and permission-less, allowing anyone with Kusama (KSM) tokens or parachain tokens to vote on their respective governance proposals. This on-chain governance procedure aims to facilitate a quicker pace of development for projects built on Kusama.

Kusama is primarily built for developers who aim to launch ambitious projects with a fast-evolving pace of development. It provides a platform for developers to test and deploy their own blockchain, making it a potential choice for projects that aim to start quickly. Kusama's interoperable and scalable nature aims to accommodate a wide range of use cases, including gaming and eSports, DAOs, marketplaces, oracles, music, and social networking. Developers can build their own app-specific blockchain and connect it to Kusama, breaking down the silos created by legacy blockchain networks.

Kusama was founded in 2019 by Dr. Gavin Wood, a world-renowned computer scientist and programmer who also co-founded Ethereum. The platform was built by the same team that created Polkadot, a company known as Parity Technologies. Parity Technologies has a team of experienced blockchain engineers and has over 100 employees spread throughout the world. Kusama is funded by grants from the Web3 Foundation, which was launched to help nurture and steward technologies and applications in the fields of decentralized web software protocols. The Web3 Foundation also supports Kusama with research and community development.

Kusama, often referred to as Polkadot's 'canary network,' is a unique blockchain platform that sets itself apart through its emphasis on innovation, experimentation, and rapid deployment. Unlike traditional testnets, Kusama operates as a fully functional blockchain network with its own economic value and governance. It serves as a pre-production environment for Polkadot, providing developers with the opportunity to test and innovate in a live, decentralized, and community-controlled network under real-world conditions. Kusama's governance parameters are adjusted to allow for quicker upgrades, which enables Kusama to adapt and evolve. The bonding requirement for running a parachain on Kusama is different from that on Polkadot. Kusama is not just a testing ground for developers; it also aims to be a platform for experiments with new ideas and innovations in areas such as governance, incentives, and decentralized autonomous organizations (DAOs).

KSM, the native token of the Kusama network, has a central role in the ecosystem. It is used for various purposes, including staking, governance participation, and bonding for chain connection. Staking KSM tokens aids in maintaining the network's security and consensus mechanism, with participants contributing to the process of transaction validation and finalization. KSM holders also have a crucial role in the governance of the Kusama network, with the ability to participate in voting on proposals and contribute to decision-making processes related to network upgrades, resource allocation, and policy changes. Moreover, KSM tokens are utilized for bonding when connecting external chains as parachains to the Kusama network. This bonding process aims to ensure interoperability and collaboration between different chains, contributing to an interconnected ecosystem. Kusama is designed to function as a blockchain that can be used for project testing prior to potential deployment on the Polkadot network.

Kusama plays a role in the Polkadot ecosystem by serving as a live testing environment for developers. It allows developers to experiment with their early Polkadot projects using real cryptocurrency transactions, ensuring that major updates and code releases undergo rigorous testing before being launched on Polkadot. Kusama has its native cryptocurrency, KSM, which operates on its independent blockchain and serves various purposes within the network, including governance, staking for network operation, bonding to connect chains as parachains, and functioning as a utility token for users. Kusama is a platform for experimentation, providing early exposure to new projects and allowing for the trial of new blockchains and applications.

Kusama parachain auctions strive to allocate limited parachain slots to projects that aim to operate on the Kusama network. The process is designed to be permissionless and competitive, ensuring that projects that meet the requirements secure a slot. The auctions follow a modified candle auction format, where the exact endpoint of the auction remains unknown until after the auction's close to prevent last-minute bidding and promote accurate price discovery. Teams bid by specifying a range of lease periods and the amount of Kusama (KSM) they are willing to commit for the duration of the chosen range. The auction continues for approximately one week, with open bidding throughout. At the end of the auction, the precise moment of the auction's close is randomly and retroactively determined. The selected parachain is automatically onboarded at the start of the lease, with the KSM amount that was bid remaining committed for the duration of the lease.

Kusama's governance model is notable for its decentralization and community-driven approach. It utilizes a system called 'proof-of-stake' where token holders may participate in the decision-making process, meaning those who hold more tokens may have more influence over governance decisions. Unlike some other cryptocurrencies, Kusama has a built-in mechanism for on-chain governance, which means that proposals and voting take place directly on the blockchain, aiming for a process resistant to tampering. Kusama also has a feature called 'referendum,' where token holders can vote on proposals and determine the network's future direction. This model aims to make decisions that reflect the interests of the community. Kusama's governance model includes a mechanism called 'Council,' consisting of elected members responsible for proposing and voting on network upgrades.

Kusama utilizes a mechanism known as runtime upgrades. These upgrades aim to allow for updates to the underlying blockchain protocol and associated functionalities without the need for a hard fork. This strives to facilitate a smooth evolution of the network and the integration of new features without causing disruptive network splits. The runtime upgrade process in Kusama revolves around on-chain governance, a system that enables stakeholders to propose, discuss, and vote on changes to the protocol. This participatory approach begins with a stakeholder submitting a proposal outlining the desired modifications or additions to the protocol. This proposal then enters a public scrutiny phase where the wider community and stakeholders engage in discussions, provide feedback, and raise any concerns they may have. After the scrutiny phase, the proposal moves on to the voting stage. Kusama’s governance model employs a weighted voting system, where the weight of a vote is determined by the number of Kusama tokens held by the voter.

Kusama network is a platform that accommodates various projects and applications. It's particularly compatible with developers who want to experiment and test decentralized applications and blockchains before deploying them on Polkadot. Some examples of projects that could be deployed on Kusama include DeFi (Decentralized Finance) applications, digital wallets, IoT (Internet of Things) applications, gaming platforms, and Web 3.0 infrastructure. Kusama's parachain model is designed to support the internet of the future, which is expected to have many different types of blockchains working together. This positions it as a platform for projects that seek to contribute to Web 3.0 and decentralized systems.

Kusama's experimentation environment is a platform that allows for the testing and development of new ideas and concepts in the cryptocurrency space. This environment, often referred to as a "canary network", is a crucial aspect of Kusama's infrastructure. It strives to provide a space where developers can experiment and innovate with the intention of minimizing potential disruptions or damages. This environment is important because it allows for the testing of new features, upgrades, and improvements before they are implemented on the main network. It provides valuable insights and data that can be used for potential improvements to the network's functionality and performance. This experimentation environment is a testament to Kusama's aim to foster innovation and progress in the cryptocurrency industry.

Kusama strives to foster an environment where community members actively contribute to the network's development and shape its future direction. Kusama's governance model is community-driven, allowing every participant to propose and vote on various initiatives, including upgrades, improvements, and policy changes. This inclusive structure empowers individuals and prevents the concentration of power in the hands of a few. Kusama incentivizes active community participation through various mechanisms. By staking KSM tokens, community members can contribute to the network's security and stability while receiving non-monetary incentives for their involvement. Kusama encourages open-source collaboration among its community members, which can result in the creation of new solutions. Kusama's interoperability with other blockchain networks can facilitate knowledge exchange and collaborative efforts to address shared challenges.
