Blockchain Technologies: Opportunities for Solving Real-World Problems in Healthcare and Biomedical Sciences PMC

One of the benefits of smart contracts is that it inherits blockchain’s strengths, like immutability. However, it also takes on blockchain’s challenges, such as security and privacy. IT leaders should understand the risk of implementing enterprise blockchain technology because of these disadvantages. These unpredictable risks should affect whether a blockchain project investment is feasible. Smart contracts on blockchain have the potential to streamline certain business processes and some business and IT leaders are looking at the potential use cases, such as in the area of advertising and healthcare.

What Is The Example Of Blockchain

As types and preferences of payment method multiply, retailers must adapt to the ways in which consumers want to pay. This has retailers looking to blockchain for at least a couple of reasons. Well, healthcare, in the U.S. at least, is broken, and those who need medical care are going broke. When nearly 20% of the nation’s GDP is spent on healthcare, something is broken, badly. Helium uses a decentralised machine network to connect anything over the Internet through a blockchain, wireless network, and open-source software. According to a Forbes report, the food industry is making the use of blockchain to track food paths and safety during its farm to user journeys.

A prior authorization request triggers a smart contract by digitally reviewing insurance coverage and releasing payment to the overseeing facility. Interest in blockchain platforms has been growing significantly as a way to streamline supply chains, improve traceability, simplify trade and improve financial transactions. A lot of this interest started with the speculative frenzy surrounding Bitcoin, which is based on an older blockchain platform that faces challenges with energy consumption and speed. Healthcare providers can leverage blockchain to securely store their patients’ medical records. When a medical record is generated and signed, it can be written into the blockchain, which provides patients with the proof and confidence that the record cannot be changed. These personal health records could be encoded and stored on the blockchain with a private key, so that they are only accessible by certain individuals, thereby ensuring privacy.


Modern-day databases are formed when numerous servers are connected and stored in a secure location. The organization that owns these servers also has considerable control over all the data stored within them. Like the internet, which has become a pivotal part of our everyday lives, and we cannot imagine life without it, so will DLT.

  • AI then sifts through the data to find trends and analyze connections that will lead to medical breakthroughs.
  • Porsche was the first automotive industry player to invest in blockchain app development together with the startup XAIN.
  • It has also developed tools to help automate the process of weaving NFTs into enterprise supply chains.
  • The proof-of-work consensus method, for example, often consumes a large amount of electricity to operate.
  • Google is also reported to be working on a proprietary blockchain to support its cloud-based business.
  • That’s because a blockchain is a continuously growing list of records and each block typically contains a hash , a timestamp as well as transaction data.

Public blockchains also help to eliminate certain challenges and issues, such as security flaws and centralization. With DLT, data is distributed across a peer-to-peer network, rather than being stored in a single location. A consensus algorithm is used for verifying information authenticity; proof of stake and proof of work are two frequently used consensus methods. The platform supports a dynamically upgradable protocol and modular software clients that enable it to adapt to new uses. The Tezos community has been upgrading the platform at a rapid clip, with recent enhancements that have improved performance and increased the size limit on smart contracts. It has also developed tools to help automate the process of weaving NFTs into enterprise supply chains.

Blockchain vs. crypto vs. web3

Blockchain is changing the mindset of businesses and governments as we know it. The sheer number of applications of the technology makes it next to impossible to list all. Once you finish reading this blog, you will get a gist of the potential -and power- of what blockchain technology has to offer. One of the biggest challenges facing the energy industry, companies in the habit of trading surplus supply need infallible record keeping. Tracking energy allocations in real time, and ensuring efficient distribution through the supply chain requires multiple data points, and also mandates close cooperation between all entities. Multiple organizations can share the responsibilities of maintaining a blockchain.

This ‘net-to-plate’ chain allows inspectors to determine whether fish had come from regions notorious for human rights abuses or from countries that are affected by economic sanctions. China is proving to be a ripe test bed for blockchain projects, for it’s also home to the world’s first agricultural commodity blockchain. As the top-ranked blockchain services provider, IBM Blockchain Services has the expertise to help you build powerful solutions, based on the best technology. More than 1,600 blockchain experts use insights from 100+ live networks to help you build and grow. For a more detailed look at how a blockchain network operates and how you can use it, read Introduction to distributed ledgers.

Instead, the blockchain is copied and spread across a network of computers. Whenever a new block is added to the blockchain, every computer on the network updates its blockchain to reflect the change. By spreading that information across a network, rather than storing it in one central database, blockchain becomes more difficult to tamper with. If a copy of the blockchain fell into the hands of a hacker, only a single copy of the information, rather than the entire network, would be compromised. Coli, salmonella, and listeria, as well as hazardous materials being accidentally introduced to foods. In the past, it has taken weeks to find the source of these outbreaks or the cause of sickness from what people are eating.
