Blockchain offers an unparalleled level of decentralisation and transparency, with a tradeoff in performance and inter-connectivity. In a foreseeable future, It is believed that blockchain solutions, especially smart contracts, will help people reach a trustless agreement at ease and in every single aspect of daily situations. However, the current approaches to achieve this either are built to make others obsolete or requires a significant change on the participating chains. KardiaChain follows an ?integration without assimilation? approach which focuses on simplicity and ease-to-use from both the end-user?s and developer?s standpoint. The KardiaChain team has developed a non-invasive solution, called Dual master node (or Dual node for short), to facilitate inter-chain operations among both existing and upcoming blockchain platforms. The ultimate goal of KardiaChain is to create a unified ecosystem where developers can easily create smart contracts that can run on multiple blockchains, i.e to optimise costs and avoid congestion and can communicate with smart contracts on other chains in a trustless and secure manner.
