Blockchain technology also deals with large amounts of data. Big Data and two industries that are benefitting from big data practice that could benefit from Blockchain technology are the oil and gas industry and the healthcare industry.The oil and gas industry is already adopting big data analytics to increase efficiency and productivity on an on-going basis, within the constrained data governance and accessibility, as it exists today. The use of Blockchain can transform the oil and gas industry to reach its goal to be compatible to Industry 4.0, at a much faster pace. For example, leveraging Blockchain, the oil and gas industry can use Smart Contracts, thus reducing time to execution, speeding the time to generate economic value for parties in the contract. Block chain can further provide speed in solving hard to solve problems of the industry, should a consortium be able to integrate knowledge from encrypted data from multiple contributors without violating the terms and conditions of the data governance. As oil and gas industry moves towards implementation of Internet of Things, Sensors, it will have hundreds of protocols exchanging information, Blockchain will be able to keep the veracity in the data, and allows one to make decisions intelligently. The oil and gas industry can learn from other industries like finance and defense. The healthcare industry has been rapidly changing over the years as well. From generalized care to patient-specific care, big data has played a role in that shift. Blockchain technology can also play a major role in how healthcare continues to grow and transform. Currently, in the healthcare industry, there is information being stored on multiple software's and facilities, all which are not connected by any means. There is no sharing of data or information across these. Blockchain technology would streamline all medical record in a secure format that would protect private data from hackers and allow patients to have more control over their personal information.Currently, for example, if a patient is transferring from one doctor's office to another, there is a significant amount of paperwork, online or physical, that needs to be done for medical records to be transferred over. However, with Blockchain technology, if a doctor is seeing a [new] patient, they will be able to view their record, from administered vaccines to prescribed medications to major and minor injuries and surgeries, with little to no hassle because that information is permanently embedded in the streamlined network. All that information will be at the doctor's disposal to treat the patient to the best of their knowledge and ability.The future of Blockchain technology will continue to grow into various industries as it is rapidly proving itself to be an extremely effective and important resource in streamlining and securing data.
