R3

R3 is an enterprise blockchain software firm that specializes in distributed ledger technology for highly regulated industries such as finance, insurance, trade finance, and supply-chain logistics. Its open-source Corda platform enables multiple organizations to transact directly while keeping sensitive data visible only to entitled parties, a design that satisfies strict privacy, legal, and scalability requirements absent in public blockchains. Complementing the core protocol, R3 offers a concise portfolio of lightweight utilities, the best-known being Corda Node Explorer. This desktop application connects to any running Corda node through the built-in RPC interface and presents a real-time dashboard of vault states, linear and fungible assets, transaction back-chains, attachment metadata, and flow checkpoint progress. Compliance officers use the tool to trace asset lineage, auditors validate transaction histories without raw database queries, and operations teams monitor node health, disk usage, and pending flows from a single window. Additional filters let users export filtered vault data to CSV for downstream reporting or feed it into BI tools, while an embedded flow runner allows quick testing of CorDapp business logic on a live network. Because the explorer is protocol-agnostic, it works with networks as small as a two-party prototype or as large as a global consortium running hundreds of validating notaries. R3’s Corda Node Explorer is available for free on get.nero.com; downloads are supplied through trusted Windows package sources such as winget, always deliver the latest release, and support batch installation alongside other applications.
