Bitcoin Gold hopes to change the paradigm around mining on the Bitcoin blockchain. According to the founders, the Bitcoin blockchain has become too centralized. Large companies with huge banks of mining computers now mine the vast majority of Bitcoin. For the founders of Bitcoin Gold, having large companies control the Bitcoin network defeats the purpose of a decentralized ledger and peer-to-peer currencies. In response, they’ve initialized the Bitcoin Gold project. It’s an alternate fork of the Bitcoin blockchain that implements changes that make mining more equitable. The goal of Bitcoin Gold is to create a network where anyone can become a miner with only basic hardware. As a result, Bitcoin Gold mining would be spread among many miners, instead of a few large companies.There have several features such as decentralization. Bitcoin Gold decentralizes mining by adopting a PoW algorithm, Equihash-BTG, which cannot be run on the specialty equipment used for Bitcoin mining (ASIC miners.) This gives ordinary users a fair opportunity to mine with common GPUs. Besides, there have fair distribution. Hard forking Bitcoin’s blockchain fairly and efficiently distributes 16.5 million BTG immediately to people all over the world who have interest in cryptos. Other methods, such as creating coins with a new genesis block, concentrate ownership within a small group. There also have a replay protection. To ensure the safety of the Bitcoin ecosystem, Bitcoin Gold has implemented full replay protection and unique wallet addresses, essential features that protect users and their coins from several kinds of accidents and malicious threats. Most new mineable cryptocurrencies involve ASIC-resistant hashing algorithms, and it’s becoming something of an industry standard to promote decentralization. In that respect, Bitcoin Gold holds a lot to be excited about. At its core, it’s about transitioning the Bitcoin network to more decentralized mining. However, as we saw above, there’s not much evidence that the current Bitcoin mining system is broken. There have been some small complaints, and it’s not ideal that the network is so centralized. Nevertheless, miners on Bitcoin have a lot to lose if they wield their power too aggressively. There are also new entrants to the Bitcoin mining community that are decentralizing control from a few key ASIC farms. The general consensus from Bitcoin experts is there’s not enough new in Bitcoin Gold to warrant an independent investment. While it certainly doesn’t hurt to hold onto your free BTG that you receive as a result of the fork (if you owned Bitcoin before Oct 24), wait until the dust settles before deciding whether to buy more.'
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.
