Airnode
Airnode, in cryptocurrency, refers to a node or device that facilitates the connection between smart contracts on blockchains and real-world external data. It is a fundamental piece of infrastructure for the implementation of smart contracts that require access to external information, such as financial data, weather conditions, or asset prices.
Airnode acts as a bridge between blockchains and external data sources, allowing smart contracts to receive real-time information securely and reliably. This data can be used to automate processes, execute agreements, and trigger real-world actions based on predefined conditions in the smart contracts.
In summary, Airnode is an essential component for interoperability between blockchains and the outside world, enabling the integration of external data into smart contracts for a wide range of applications and use cases in the cryptocurrency and blockchain technology space.
