Cross-consensus message format, or XCM, is a messaging format and language used to communicate between consensus systems.
XCM is designed to provide a generalized and extensible set of instructions that can facilitate the completion of transactions across different consensus systems, transaction formats, and transport protocols.
A Closer Look At XCM
One of Polkadot’s primary functionalities is interoperability between its different parachains and other consensus-driven systems. XCM is essentially the language that allows two blockchains to interact with one another and conduct complex cross-chain interactions. However, XCM is not specific to the Polkadot network. The primary function of XCM is to define a generic format that allows different consensus systems to communicate with one another. XCM also does not define how messages between two consensus systems are delivered. Instead, it defines how the message should look and act and contains instructions for the inten
