What is KardiaChain (KAI) ?

KardiaChain is a blockchain platform that aspires to be fully interoperable and "non-invasive," which means that blockchains can join to the network without modifying their protocols. KardiaChain employs a dual-node topology, sharding for scalability, and smart contracts for developers to ease the connectivity between its own ledger and other blockchains.KardiaChain promises to be the first blockchain that is completely non-invasive and interoperable. It does this primarily through its dual master node technology, which allows the blockchain to access both its own ledger and that of other platforms at the same time. This enables KardiaChain to work alongside other blockchains without asking them to change their protocols or technologies. Dual nodes may be controlled by anybody, making them permissionless, and feature a consensus method to check data from both chains, according to the whitepaper.
