Communication Protocols

Definition ∞ Communication protocols are sets of rules and conventions that govern how data is exchanged between different computing devices or systems. These protocols define the format, timing, sequencing, and error checking of messages to ensure reliable and orderly data transmission. They are essential for enabling interoperability and consistent interaction across networks.
Context ∞ In cryptocurrency, communication protocols are the bedrock of blockchain networks, dictating how nodes interact, validate transactions, and reach consensus. News often touches upon upgrades or discussions concerning these protocols, such as changes to network messaging or inter-blockchain communication standards. Understanding these protocols is key to comprehending network performance, security vulnerabilities, and the potential for cross-chain functionality.
