Blockchain technology is the basis of most cryptocurrencies, but the Health Sector Cybersecurity Coordination Center’s (HC3) latest brief suggested that blockchain has a multitude of useful applications in the healthcare sector.
A blockchain is a tamper-resistant, secure, and collaborative ledger that maintains transactional records, HC3 explained. A block is a unit of data, or one record, that contains a collection of transactions. When arranged with other blocks in a specific order, a blockchain is formed.
Each block contains data, a hash, and a previous hash. The purpose of the blockchain dictates the type of data. A hash is a digital fingerprint that identifies the block, and a previous hash links the current block to the previous block, providing an extra security measure.
“A block is connected to the previous one by including a unique identifier that is based on the previous block’s data. As a result, if the data is changed in one block, it’s unique identifier changes, which can be seen in every subsequent block (providing tamper evidence),” the National Institute of Standards and Technology (NIST) explains on its website.
