What is the difference between Multichain and Cosmos(Tindermint)? Is the working principle same? In case of Cosmos, there are multiple parallel blockchain running and they can communicate with each other via BCI. In multichain, can we do similar actions. I would like to work on multiple blockchains working in parallel and all the Blockchains are independent with each other. In this case, will it be a permissioned or permissionless blockchain.
