When you start talking about blockchain in healthcare, inevitably the first question people ask is what’s blockchain? If you find yourself doing the same, here’s the quick and dirty rundown on how this revolutionary new technology works and why it’s causing so much buzz in industries around the world, including healthcare. What Is Blockchain? The easiest way to think of blockchain is as a decentralized, secure public ledger that tracks transactions and allows users to verify them without an intermediary like a bank or government regulator.

What is blockchain?
A blockchain is a digital ledger of all cryptocurrency transactions. It is constantly growing as completed blocks are added to it with a new set of recordings. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data. Bitcoin nodes use the block chain to differentiate legitimate Bitcoin transactions from attempts to re-spend coins that have already been spent elsewhere. To carry out this function, bitcoin uses Hashcash puzzles. When someone wants to send bitcoins over the network, they must solve these puzzles by guessing until they find a correct one. The puzzle difficulty is automatically adjusted so that no matter how many people are trying to guess at once, only one person can successfully complete the puzzle every 10 minutes on average (and no more than six). The more people who try to guess at once though, the harder it becomes for everyone.
How Can Blockchain be Applied to Healthcare?
Blockchain is being used in a variety of ways in healthcare today. For example, it is being used to create secure, decentralised databases of patient health information. This allows for better data sharing and collaboration between different healthcare providers. Additionally, blockchain is being used to create tamper-proof medical records and to streamline clinical trials. Some startups are even using blockchain to develop new ways to pay for healthcare services. While blockchain holds a lot of promise for the healthcare industry, it is still in its early stages of development and adoption.
How Is Blockchain Being Used in Health IT Today?
A blockchain is a digital ledger of all cryptocurrency transactions. It is constantly growing as completed blocks are added to it with a new set of recordings. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data. Bitcoin nodes use the block chain to differentiate legitimate Bitcoin transactions from attempts to re-spend coins that have already been spent elsewhere. As long as a majority of computing power on the network is controlled by nodes that are not cooperating to attack the network, they’ll generate proof-of-work blocks together and outpace attackers.
How Can You Use Blockchain in Health Care?
Though blockchain technology is still in its early stages, it has the potential to revolutionise how healthcare systems operate. By streamlining data sharing and making it more secure, blockchain could help improve patient care while also reducing costs. However, there are still many challenges that need to be addressed before blockchain can be widely adopted in healthcare. For now, it remains an exciting and promising technology to keep an eye on. Here are five areas where blockchain could have a positive impact
Final Thoughts on Blockchain in Healthcare
1. So far, blockchain has been most useful in healthcare for managing provider data and identities, sharing medical records, and tracking clinical trials.
2. That said, the technology is still in its early stages and has a long way to go before it can truly revolutionise healthcare.
3. For now, blockchain is best used as a supplement to existing systems rather than a replacement for them.
4. As the technology matures, we may see more widespread adoption of blockchain in healthcare, but only time will tell.
5. In the meantime, it’s important to keep your expectations in check and not get too caught up in the hype.
