It is important to understand what a blockchain system is: a blockchain is a growing list of records, called  blocks , which are linked using  cryptography . Each block contains a cryptographic hash of the previous block a timestamp, and transaction data (generally represented as a Merkle tree). By design, a blockchain is resistant to modification of the data. It is “an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way. A blockchain is, in the simplest of terms, a time-stamped series of immutable record of data that is managed by cluster of computers not owned by any single entity. Each of these blocks of data (i.e. block) are secured and bound to each other using cryptographic principles (i.e. chain). Now that we’ve got a basic understanding of what a Blockchain System is we can dive right into understanding hybrid blockchains. Hybrid Blockchain Hybrid Blo...

The blockchain era has already begun. Taking into account the fast progress in the development of new and more efficient healthcare record systems, wearable devices, and medical examination systems implementing artificial intelligence, cryptography will become an important part of the way hospitals work. There are, however, a few improvements still needed in order for seamless blockchain adoption across the entire medical industry.  According to Hyperledger’s survey, 42.9% of healthcare organizations suppose that the interoperability of electronic health records will help for faster blockchain implementation; with 28.6% of respondents ready to use this technology in care settings today . So, what are the benefits of blockchain technology in healthcare? Data Provenance and Integrity With an ongoing increase in patient numbers, healthcare providers have to manage more and more health data on a regular basis. As the data volume increases each year, it becomes harder for hos...
