Provenance captures the origin and life journey — including the ownership history — of a physical or digital asset. By recording it on a distributed ledger, provenance information becomes more trustworthy.
Chronicle is our open-source, blockchain-backed, domain-agnostic product for immutably recording and querying provenance data.
Chronicle makes it easy for organizations to develop domain-specific provenance solutions.
Chronicle records provenance information of any physical or digital asset on a distributed ledger to ensure that it is tamper-proof; and is available with Hyperledger Sawtooth as its default backing ledger, with support for other industry-leading distributed ledgers in the pipeline.
Chronicle is built on W3C’s PROV Ontology specification, which provides a foundation to implement provenance applications in various domains that can represent, exchange, and integrate provenance information generated by multiple parties, in different systems, and under diverse contexts.
Chronicle uses the lightweight JSON-LD linked data format, and the GraphQL data query and manipulation language, providing a comprehensive description of, and easy access to all provenance data from a single endpoint. Alternatively, there is a command-line interface (CLI) for integration with enterprise legacy systems.
Chronicle is a domain-agnostic offering, however, it is easily configurable to enable users to model, capture, and query provenance information for a range of applications or use cases such as the traceability of artwork, critical infrastructure, food items, medical devices, precious metals, or real estate, just to mention a few.
Chronicle is powered by our management platform Sextant, to facilitate its deployment and management, as well as its integration with enterprise systems. Our flexible deployment options include multi-cloud, on-premise, and hybrid environments, leveraging the industry-leading container orchestration tool Kubernetes.
