Kusama test network, which is officially described as Canary Network, implies that the birds flying to explore the path before Polkadot goes online, to eliminate possible problems in advance, so as to ensure that the main network goes online smoothly. Kusama will be fully functional, almost the same as Poka Chain Polkadot, except that the experimental network will not disappear after Poka Main goes live. Future participants in the Polkadot network, such as Verifier nodes, parallel chain teams, and builders of Poca's ecological tools, can use Kusama to prepare ahead of time and fully test.
