Cold Chain

Transparency. Traceability. Assuredness. Supply chain workflows for temperature sensitive assets using Blockchain technologies.

Sample interface of Media Sourcery Authorization Product

COVID-19 test kits. Vaccines. Food products. These are just some of the assets that require a certain temperature as they are stored and transported from the original manufacturer to the point of usage. Media Sourcery's Cold Chain Workflow solution utilizes blockchain technologies such as a public distributed ledger to provide traceability and transparency - to provide trust.

Transparency and Traceability for each User

As with all Media Sourcery solutions, the right information at the right time


End Users. Whether the end user is a Lab, a patient, a grocer, a consumer or other entity, each user will be able to view through the Media Sourcery Cold Chain solution the path their asset(s) have traveled with all the metadata that is associated with that asset. This metadata can include storage and transport temperature, GPS coordinates, time stamps, documentation, the identity and calculated reputation of the person or system that loaded the metadata, and many other attributes. If there is an end of life or expiration on the asset, end users will be notified before and on this date.


Manufacturers and Distributors. Owners of the asset(s) throughout the cold chain cycle can not only create and transfer assets, but also track them through their life cycle. This includes verifying correct temperature storage at the own premises and upon delivery downstream from them.


Identity for all. Using Media Sourcery's integrated Authorization Service, enterprises and end users can choose how to authenticate and be authorized to use the solution. Enterprises can use Active Directory, email domains or other directories. Individuals can choose to use decentralized identities such as Blockstack, Consensys uPort and others.

Ensuring Trust and Automation with Technology

The Media Sourcery Cold Chain Workflow solution offers bulk asset creation (for creating many of the same asset at once), fingerprinting (providing documentation for events where a real-time event was not recorded) and other milestone events. The events in the life of an asset are recorded on distributed ledger technology on a blockchain from our partners, Topl. These events include creation, transfer, shipment and end-of-life. Fingerprinting can be provided by a variety of distributed ledger technologies, including arweave, Blockstack's Gaia storage and IPFS (integrations to these distributed storage systems can also be seen in our Data Messenger (document uploader) solution).

The most important metadata for an asset on a cold chain is temperature. This includes temperature at rest and in motion. Temperature at rest should be measured through a site independent device, with those measurements stored on a distributed public ledger for traceability and trust. Temperature in motion can be measured at each endpoint. Media Sourcery has partnered with VarCode, using their unique chemically constructed barcodes to verify that prescribed temperatures were not exceeded at any point during the life of the barcode.

Through integration with Media Sourcery's ETA (Events, Triggers, Actions) rules engine, the Cold Chain solution allows notification and action based on events at each point in the cold chain. These events could include asset expiration, shipment and temperature alerts. The resulting actions could include notifications via text, programmable voice or email, and will include more complex tasks, such as release of payment upon verified temperature at end of shipment, or insurance claim upon verified violation of temperature requirements.
