KardiaChain is a blockchain platform that aims to be fully interoperable and &quot;non-invasive,&quot; meaning that blockchains can connect to the network without needing to make technical modifications to their own protocols. KardiaChain uses a dual-node structure to facilitate the connection between its own ledger and other blockchains, sharding for scalability and smart contracts for developers. 
The platform relies on a native token, KAI, which is used for staking, transaction fees, participating in services and deploying smart contracts.
