Parachains are Kusama’s advanced, next-generation blockchains that bring several breakthroughs compared to legacy networks. Together they form the Kusama ecosystem, an interconnected network of specialized chains breaking down the walls of the centralized web.
A single, limiting design for the entire network. No ability to optimize for specific use cases, so compromises and tradeoffs must be made.
Parachains are specialized for a multitude of use cases, enabling more optimized services and thriving, multifaceted economies.
Most blockchains are like walled gardens, cut off from each other and unable to communicate, prohibiting the free flow of data and commerce.
Parachains are a rich, interconnected ecosystem where data flows freely between chains, leading to innovative new interoperable services.
Transactions are processed one-by-one, leading to bottlenecks, network congestion and high fees when dapp usage spikes.
Parachains process transactions “in parallel”, spreading them across the entire multichain network for maximum scalability.
Like all software, blockchains need periodic upgrades to stay relevant. Upgrading most blockchains is painstaking, making them slow to evolve and respond as new technology becomes available.
Kusama makes upgrading a blockchain more like upgrading a conventional app, with the ability to make most updates seamlessly and automatically in the background.
Legacy blockchains are dependent on centralized organizations to finance activities that benefit the network, and communities as a whole have no financial agency.
Parachains can leverage on-chain treasuries, giving decentralized communities the financial agency once limited to corporations and governments.
Most blockchains have no formal governance procedures. Individual stakeholders are often powerless to propose changes, with decisions made by opaque groups of insiders.
Parachains can leverage Kusama’s built-in, transparent governance features or create their own to implement the system that’s best for their community.
Securing blockchains requires a massive amount of resources, creating a significant barrier to entry for new chains and leading to competition for scarce resources between chains.
Parachains get robust security automatically when they connect to Kusama—no need to bootstrap their own network of miners or validators.
Building a conventional blockchain typically takes years of hard work and large teams of experts. Maintenance is costly and time consuming.
Parachains can use the Substrate blockchain framework to drastically simplify and speed up development and maintenance.
Fees on blockchains are often unpredictable, fluctuating based on short-term network usage and congestion.
Transaction fees are known in advance and fee structures can be customized by parachain teams. Users can pay fees in the parachain’s native token.
Blockchains and smart contracts are typically limited to a few basic transaction types, like sending funds or triggering a contract. Transactions between chains are limited and often mediated by centralized services.
Kusama allows any type of data to be sent between dapps and parachains, creating an interoperable internet of blockchains and opening the door to a host of innovative new services.
