Component Overview

1. Understanding R3 Corda Networks

R3 Corda Networks is built on the principles of distributed ledger technology (DLT) and offers a unique approach to blockchain networks tailored specifically for enterprise use cases. Unlike traditional public blockchains like Bitcoin or Ethereum, Corda Networks adopts a permissioned model that ensures confidentiality and privacy while facilitating secure transactions between known participants.

2. Architecture and Component

2.1 Node Architecture

Corda Networks comprise a network of nodes, with each node representing a participant in a business network. Each node maintains its own copy of the ledger and executes transactions independently. The architecture is designed to ensure privacy by restricting access to information only to the relevant parties involved.

2.2 Corda Ledger

At the core of R3 Corda Networks lies the Corda Ledger, a shared, immutable data structure that records the evolution of business agreements and transactions. The Corda Ledger is not a traditional blockchain, as it employs a unique "transaction chain" approach. This design choice enhances privacy and scalability by eliminating the need for global consensus among all network participants for every transaction.

2.3 Smart Contracts

Corda Networks utilizes smart contracts, called "CorDapps," to automate business processes and enforce the agreed-upon rules among participants. CorDapps are written in programming languages such as Java or Kotlin, allowing for flexibility and extensibility. These smart contracts enable participants to transact directly, reducing complexity and facilitating efficient business interactions.

2.4 Notaries

To ensure the integrity of transactions, Corda Networks employ notaries, specialized nodes that validate and timestamp transactions. Notaries serve as trusted authorities and prevent double-spending or conflicting transactions from being included in the ledger. Participants can select the type and number of notaries based on their specific requirements.

3. Key Features and Capabilities

3.1 Privacy and Confidentiality

Corda Networks prioritize privacy by design. Transactions are shared only with relevant participants on a need-to-know basis, utilizing state-of-the-art cryptographic techniques. This confidentiality feature makes Corda Networks an ideal choice for industries where sensitive data must be protected, such as finance, healthcare, and supply chain management.

3.2 Scalability

Corda Networks offer high throughput and scalability by leveraging its unique transaction chain model. Unlike traditional blockchains that require every participant to process and validate all transactions, Corda allows for selective sharing of transaction details, resulting in improved performance and scalability for complex business networks.

3.3 Interoperability

R3 Corda Networks support interoperability, allowing seamless integration with existing systems and technologies. Participants can connect Corda Networks with legacy systems, databases, and external APIs, enabling the exchange of information and assets in a standardized and efficient manner.

3.4 Regulatory Compliance

With its focus on enterprise use cases, R3 Corda Networks provides built-in features for regulatory compliance. These include the ability to record and audit transaction details, manage data privacy and sharing permissions, and enforce legal agreements through smart contracts. Such compliance features ensure that businesses can operate within the framework of relevant laws and regulations.

4. Use Cases of R3 Corda Networks

Trade Finance:

R3 Corda is well-suited for trade finance applications. It enables efficient and secure settlement of trade transactions, automates processes, reduces paperwork, and enhances transparency among parties involved in international trade.

Supply Chain Management:

Corda can be utilized in supply chain management to enhance transparency, traceability, and efficiency. It enables real-time tracking of goods, verifies the authenticity of products, streamlines processes, and reduces fraud and counterfeiting risks.


R3 Corda can streamline insurance processes by automating claims management, policy administration, and contract execution. It enhances transparency, reduces fraud, and facilitates faster claims settlements.


Corda can be applied in healthcare for secure and interoperable sharing of medical records, clinical trials data, and health insurance claims. It enables privacy-preserving transactions while ensuring data integrity and consent management.

Financial Services:

R3 Corda can be used in various financial applications such as cross-border payments, asset tokenization, syndicated lending, and regulatory compliance. It enables faster settlement, reduces intermediaries, and enhances transparency in financial transactions.

Identity Management:

Corda can provide secure and decentralized identity management solutions. It enables individuals and organizations to maintain control over their digital identities, securely share personal data, and streamline identity verification processes.

These are just a few examples of how R3 Corda Networks can be utilized. Its flexibility, privacy features, and focus on enterprise requirements make it suitable for a wide range of industries and applications.

5. Internal Network

CatBM allows customers to create Corda nodes on their own networks, but we also offer managed networks. We call this an Internal Network as it is bootstrapped internally with a single Notary. Customers may add or delete nodes in this internal network, just as they would on an external network.

The health of an internal network can be checked on the UI, as it is reflective of the status of the notary within the network. A Corda network is considered unhealthy if the notary is not in a functional state, as they play a critical part within the network.
