How Blockchain Can Be Used In Healthcare & How It Works?

  1. 1. How Blockchain Can Be Used In Healthcare & How It Works?
  2. 2. INTRODUCTION: • Health information technology and information security specialists are hearing a lot about blockchain these days. “It’s the answer to interoperability.” And “the technology can solve healthcare’s looming security problems.” • The so-called digital ledger technology was developed in 2008 by a possibly pseudonymous person,Satoshi Nakamoto. He designed it as the underpinning for the exchange of the digital cryptocurrency known as Bitcoin. • Blockchain transactions are logged publicly and in chronological order. • The database shows an ever-expanding list of ordered "blocks," each time-stamped and connected to the block that came before it. Hence, thereby constituting a blockchain. Copyright© BlockchainCouncil 2
  3. 3. • Crucially, each block cannot be changed, deleted or otherwise modified: it's an indelible record that a given transaction occurred. That’s exactly what has many in healthcare excited about blockchain's potential for data security. • It's open and decentralized nature could lend itself well to managing health records and proving identity. • Rather than a central database, the blockchain record can be distributed and shared across networks. • This is done with credentialed users able to add to – but not delete or alter – the transaction log. • Transactions are encrypted and must be verified by the network.

  4. 4. How does it work? • "For example, if any node on the network tries to transfer a particular asset twice, to two different parties, that transaction would not be validated by others on the network, and there would be no agreement to add it as a new block on the chain," said Behlendorf, executive director of Hyperledger, an open-source collaborative launched by the Linux Foundation to advance the use of blockchain beyond Bitcoin transactions. • Behlendorf also spotlighted the importance of so-called smart contracts on the blockchain ledger: "simple software programs that run on all nodes in the network and can extend the validation logic at each node in a way that is automatable and undeniable." In healthcare, for example, such smart contracts could be deployed as an "authorization process and confirmation step that notifies the patient – or even puts them in control – when their data is shared from one address to another."

  5. 5. • Behlendorf said that because blockchain technology is distributed by design, storage space is limited, so small data or metadata is preferable. • The option is to store records or files either on- or off-chain, he said. • Large healthcare files such as imaging scans or PDFs wouldn't need to be stored entirely on the chain but could be linked to it with a hash, or cryptographic numeric fingerprint, to ensure it hasn't been altered.
