An Open and Collaborative Network

Blockchain has the power to revolutionize the pharmaceutical industry.

Blockchain has the capacity to break apart the silos dividing pharmaceutical suppliers and customers, while also building bridges for secure record keeping of each transaction that protects every party and ensuring fidelity across supply chains.

Imagine - an industry-wide network owned by the industry itself, connecting you to all your suppliers and customers. This is not the future - it is happening now.

The MediLedger Network gives you the power to:

We are going live in October, 2019 with a solution for Saleable Returns - a combination look-up directory and verification routing service that can enable sub-second responses between wholesalers and manufacturers. We have tested and proven it works.

about the project

A Network Governed by Industry

The MediLedger Project was launched by2017. It brings together leading Pharmaceutical Manufacturers and Distributors using an advanced and customizable decentralized supply chain management system based on the principles of blockchain. This dynamic system innovates evolving solutions for track and trace regulations, and provides a step function improvement in the overall operation of the supply chain.

The MediLedger Project is building an industry-owned permissioned blockchain network for the pharmaceutical sector based on open standards and specifications.

Network nodes are set to be distributed among and operated by industry participants and technology providers who serve the industry.

This decentralized network is only possible because the MediLedger Project has solved the sensitive issue of data privacy. No business intelligence is shared between partners, but rules are still enforceable due to zero-knowledge transaction verification across the supply chain.

This approach can create a vibrant, open development environment and unlock innovative solutions for the pharmaceutical industry beyond the limits of what current technology can offer in the marketplace.

The MediLedger Network


Delivering Value

The MediLedger Project is built to give pharmaceutical partners a way to keep up with evolving track and trace compliance regulations as well as find better ways to partner inside a shared ecosystem.

We believe that blockchain has the potential to transform partner relationships, and provide a secure, private and trust-building network for pharmaceutical leaders to record the change of ownership of prescription medicines. We have a tested protocol for DSCSA Saleable Returns and have created an Industry Look Up Directory and Verification Router Service that is available now.

We are meeting the emerging needs of the prescription medicine supply chain through redefining the potential of blockchain for the pharmaceutical sector.
