The Darwinia Crab Network (abbreviated as Crab Network) is an economically valuable canary network for Darwinia, positioned similar to the Kusama network for Polkadot, and Expect Chaos is a reasonable expectation. The Crab network mainly provides a pre simulation environment for the upgrade and application deployment of Darwinia, and conducts various radical experiments. The Crab network not only includes a complete software running environment and network environment, but also includes the economic environment of economic games.Crab network is the first cross chain NFT chain in Poka ecology. It provides smart contract solutions, is compatible with Ethereum virtual machines, and supports Defi, NFT and other Dapps to easily migrate to Poka. The bridge technology innovation based on Darwin Network also provides an entrance to Poka ecology for projects that have been deployed in Ethereum, BSC and other public chains. The parameters of the Crab network are the same as those of the Darwin main network, and use the same Stacking mechanism and inflation model.There are two types of tokens in Crab Network. They represent different economic strategies of Crab Network. They aim to make Crab more reasonable and stable.The native token of Crab Network is CRAB, which can be used as a trading gas. Gas includes transaction costs, contract execution costs, network bandwidth costs, storage costs, etc.To encourage users to make long-term commitments, they can choose to lock in CRAB for 3-36 months during the stacking process, and the system will provide CKTON tokens as rewards for participating users....
