Data stored on blockchain is rendered tamper-proof because the network of nodes the disparate computers on which the shared database is stored, and which validate transactions can cross-reference to locate the source of a disputed change, so the technology has a number of potential cybersecurity applications. Storing information across a network of devices reduces the risk of a hacker exploiting a single point of vulnerability. Similarly, decentralizing control of edge devices which provide an entry point into enterprise or service provider core networks and Internet of Things devices can render these devices more secure against attacks.
A decentralized, secure, trustworthy blockchain system has clear applications for the storage of healthcare records. Personal health records PHR collect data from sources including medical centers, devices, clinics, and pharmacies, and are primarily managed by patients. As patients manage PHRs, the validity of that information is sometimes doubted. Storing them on blockchains would ensure they are traceable, transparent, unchangeable, auditable, and secure. EHRs, on the other hand, are typically stored in centralized legacy systems, which may not be interoperable between different healthcare facilities.
Blockchain could offer a solution, with EHRs stored securely on a decentralized system that can be accessed — by both patients and healthcare workers — across systems and organizations. In many cases, this digital art already exists and is freely available on the internet for anyone to view, buy, or download.
What an NFT confers is ownership of that art. Think of it as the difference between owning an original painting and a print of it. Recording and storing high-value, high-volume pieces of data is inherent to the voting process. This makes blockchain an ideal technology for updating the voting system. Because all nodes on a blockchain must verify any information entered onto it, people could potentially cast their votes online without fear of fraud.
It also creates greater certainty for electoral officials, who can tally votes certain in the knowledge that each is attributable to only one individual. This online program examines the fundamental changes that blockchain brings to business and economics, and will equip you with the tools to leverage blockchain technology to drive innovation and efficiency in your organization.
