The public chain project Polkadot wrote an article introducing the specific differences between Kusama and Polkadot. Kusama and Polkadot are two separate networks, but both are built on similar code bases. Kusama has faster governance parameters and entry thresholds And Polka is relatively more conservative, giving priority to stability and reliability with a slower and more organized governance and upgrade process. Kusama is more suitable for bold experiments and early deployments, and Poka is designed for high-value and risk-averse applications. From a specific user case, Polka believes that it is recommended to run enterprise-level or B2B applications, financial applications, or high-value applications that require bank-level security, stability, and robustness in the Polka network, and recommend early startup networks, Experimental ideas run on the Kusama network.
