Cosmos decided to replicate the Polkadot framework by creating a prototype of Kusama called the Sagan blockchain, which acts as a testnet for smart contracts. This form of work organization allows you to release stable versions of the code to the main network, reducing the level of bugs. All tokens issued on Sagan, whose logo was placed in the background of the "constellation of the canary", will have real value. Digital assets can be transferred to the main "working" blockchains for trading on the DEX and CEX exchanges. This will allow the creators of smart contracts to launch IDOs, bounty programs, airdrops, etc., even at the MPV stage.
