Blockchain is a peer-to-peer network of connected nodes, or blocks, linked together by cryptography. It is the technology that powers cryptocurrencies like bitcoin and Ethereum. Every transaction in this ledger is validated and protected against fraud by the owner's digital signature, which also serves to authenticate the transaction. It is very secure and decentralized. The blockchain's features guarantee that any copy of the data is always accessible, verifiable, and reliable.
Blockchain is one of the biggest technological breakthroughs since the internet, and it has the potential to improve many aspects of daily life, including healthcare. For instance, blockchain might be used by government agencies that deal with sensitive personal health information to keep such information on a secure network and enable communication between the civilian population and healthcare providers. Another aspect would be identity management and verification. The organization of this data as nodes on a blockchain increases the security, speed, and accuracy of these procedures.
