Nodes in a Corda network operated under a trust-less model and run by different organizations.
Nodes communicate directly with each other using the Advanced Message Queuing Protocol (AMQP), which is an approved international standard (ISO/IEC 19464) and ensures that messages across different nodes are transferred safely and securely.
A Complete Guide to Understanding This Blockchain Concept
AMQP works over Transport Layer Security (TLS) in Corda, thus ensuring privacy and integrity of data communicated between nodes.
Nodes also make use of a local relational database for storage.
Messages on the network are encoded in a compact binary format.
They are delivered and managed by using the Apache Artemis message broker (Active MQ).
A node can serve as a network map service, notary, Oracle, or a regular node.
Why This Matters for Blockchain Technology
Understanding Nodes is not just an academic exercise — it has real-world implications for how blockchain systems are designed, deployed, and secured. Whether you are a developer building decentralized applications, a business leader evaluating blockchain adoption, or a curious learner exploring the technology, this knowledge provides a critical foundation.
