Abstract: Several factors have contributed to an increased demand for an enterprise blockchain in various industries such as reduced administrative cost, faster transaction processing, reduced likelihood of fraud etc. Several blockchain applications and technologies have emerged, however, there is a need to interoperate with various blockchain platforms by defining the interoperability semantics. Embodiments herein provide a method and system for a framework to orchestrate and manage the transactions within or across various blockchain platforms without making any change to the underlying platform protocols. Framework allows to orchestrate operations within or across various blockchain platforms without impacting blockchain protocol layer thereby reducing time and effort needed in creating targeted interoperability solution for each blockchain platform.
