Polkadot XCM: Seamless Interoperability Across Any Blockchain! 💬🌐
Cross-Consensus Message Format (XCM) is Polkadot's flagship feature. By June 2025, XCM allows parachains and external blockchains (via bridges) to securely exchange messages and assets, even if they have different rules and logic. This eliminates the need for centralized bridges, which are often points of failure. XCM makes Polkadot a true "Internet of Blockchains" where data and value can flow freely, opening up new possibilities for cross-chain applications and DeFi.
