A Decentralized Ecosystem with Built-in Privacy Owned by the Industry

Network Vision

The benefit of blockchain lives in its function. By bringing together companies drawing on the same standards to execute their business processes, blockchain makes non-competitive business functionality easier and more efficient, so companies can focus their resources on their core missions.

We have a vision of a blockchain with strong cross-industry functionality for partnerships fueled by an advanced network and tools where all partners adhere to set standards but avoid the problem of vendor lock-in.

The MediLedger Network was born out of these ideas. Now, as the industry adapts to the demands of meeting evolving track and trace regulatory requirements, this vision is becoming a reality. The network is expanding, and Chronicled is continuously incorporating industry feedback to ensure that industry goals and requirements are realized.

Network Policies

As the network evolves, the goal is to transition to an industry-owned foundation that oversees the network to ensure it serves the industry’s needs.  Part of this process is to establish network IT policies, and our current working group is assisting in this area.
