Bluzelle is a decentralized, scalable database service that aims to provide an effective data storage solution for the newly emerging blockchain ecosystem. It provides a solution to the scaling problems that developers of decentralized applications (dApps) face while using centralized infrastructure and traditional cloud-based databases. Bluzelle uses reliable ”swarm” technology, in which it stores tiny bits of data in groups of nodes or “swarms” which are distributed across the globe. Since this makes it independent of single data centres, Bluzelle’s scaling ability is limitless. Bluzelle adjusts the number of nodes and their location dynamically, reducing request time and improving overall performance. Bluzelle's swarm technology makes it extremely reliable as it redundantly stores pieces of data across the globe, eliminating a single point of failure. Since there are no data centres, Bluzelle’s resources are provided by network “producers”, who earn funds and pass on the savings to users. Bluzelle held an ICO from January to February 2018, selling 33% of its total supply of 500 million BLZ tokens and earning $19.5 million USD in the process. As of July 2018, Bluzelle has a circulating supply of about 183.02 million BLZ, with an individual price of $0.328 and consequently a market cap of around $60.25 million USD. The potential of an endlessly scalable storage service which is quick in its scaling, which is capable of storing any amount of data in a decentralized manner, is one that many investors may have an eye for. BLZ is still new and in its beginning stages, but its experienced team and excellent advisors work in its favour and are indicative of a bright future for the BLZ token. Investing in the token may not give high returns in a short period (since the cryptocurrency is so new and difficult to predict). So some more research is advised.
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.
