Medicalchain uses blockchain technology to securely store health records and maintain a single version of the truth. The different organizations such as doctors, hospitals, laboratories, pharmacists and health insurers can request permission to access a patient’s record to serve their purpose and record transactions on the distributed ledger. Medicalchain provides solutions to today’s health record problems. The platform is built to securely store and share electronic health records. By digitizing health records and empowering users we can leverage countless industry synergies. Medicalchain is building a platform for secure storage and utilization of electronic health records on the blockchain. The company is also building a telemedicine platform to allow users to directly connect with healthcare professionals, share their records and get consultations, second opinions, online through a secure channel.The company was originally founded in February 2016 to provide a software solution inside hospitals. The solution is known as ‘Discharge Summary’ and it uses a workflow tool to accurately write an assessment of a patient as they are being discharged from surgery or a long hospital visit. The software is currently being used by hospitals in UK and the team decided to extend this project and go further with Medicalchain. Medicalchain wants people to have access to their health records everywhere. Today, you can travel far and wide and you will have access to your phone, contacts, photos, files, bank accounts but not your health records - probably the most important and life saving information you need. In most developed countries around the world you, as a patient, have a legal right to request your records. Medicalchain is providing you with a platform to do that. But more importantly, Medicalchain wants its users to be able to use it immediately by communicating and sharing (on a time limited basis) with other doctors. The bigger vision is to allow pharmaceutical, insurance and other healthcare organisations and stakeholders to be able to interact with health records on patients' terms. Medicalchain believes that health records should be a part of everyone’s life and not just referred to when someone is ill.
Waltonchain is a genuine, trustworthy and traceable business ecosystem with complete data sharing and absolute information transparency. It is created by the combination of technologies of RFID and blockchain, which push forwards the integration of block chain and the Internet of Things. Waltonchain combines blockchain with IoT (specifically RFID) to create a management system for supply chains. The project is named after Charlie Walton, the inventor of RFID technology and a pioneer in the space. Logistics systems are complex and commonly involve several different parties. As these systems grow, it becomes increasingly tough for businesses in the same vertical to coordinate with each other. On top of that, individual entities may have different processes that further hinder the ability to transfer data back and forth. Waltonchain uses RFID identification to track products during each step of production and distribution. The data associated with each item is stored on an immutable blockchain that ensures its accuracy no matter where in the process it is.The Waltonchain team is loaded with supply chain experience. Do Sanghyuk, one of the co-founders, was previously the Director of the Korean Standard Products Association. The other co-founder, Xu Fangcheng was the Supply Chain Management Director of Septwolves Group Ltd. The team is getting support from their Chief Scientist Advisor, Kim Sukku – a former vice president of Samsung. Waltonchain has no shortage of partnerships – several of which are with Chinese provincial governments. The team is working with the Fujian government to create a “smart maritime” blockchain incubator, and with the Jinhu government to build smart air purification and monitoring systems. The Waltonchain architecture makes use of a novel consensus mechanism known as Proof-of-Stake & Trust (PoST). Waltonchain innovates on the traditional proof-of-stake (PoS) model and integrates a node reputation based system into the consensus mechanism. PoST provides for adjustable difficulty for each node, to ensure that integrity in the ecosystem is rewarded. Waltonchain also gives sub-chain developers the option to choose their own consensus mechanism, for example, sub-chains can strictly just have PoS as a consensus mechanism, and not PoST. Waltonchain, by use of its RFID technology, has introduced a novel way with which blockchain can solve not only the inefficiencies found with supply chain management, but also IoT.
