If you have bought Bitcoin, then you have used a blockchain without even realising it. Blockchain is a technology that isn’t limited to cryptocurrencies. Many companies are now using blockchains to help optimize their businesses and improve security. This technology provides a secure and efficient way to track data and transactions. If you want to understand how blockchain is changing the world, you need to know how the technology works.
Blockchain explained
If you have researched how to purchase cryptocurrency, you have likely come across the concept of the blockchain. A technology called blockchain records transactions on a ledger.
Here’s how transactions work: First, a transaction is included in a block. Next, the block is validated by the nodes. If the new block is verified, it is added to the blockchain. Finally, the update is broadcasted across the peer-to-peer network. Looking at past transactions can help you understand an item’s complete story. A new block will be added to the chain as new transactions occur.
A blockchain’s accessibility depends on how it is set up – it can be open to anyone or restricted to certain users.
An example of a public blockchain network would be Bitcoin, where anyone can participate. A business might use a private blockchain network to keep their data private.
Who invented blockchain?
In 1991, Stuart Haber and W. In a paper published in the Journal of Cryptology, Scott Stornetta introduced blockchain as a concept and discussed the benefits of a “chain” of timestamps for verifying digital document authenticity. from 1991 to 2008, people continued to develop ideas relating to the blockchain, building off of the work of those who published before them. Nick Szabo coined the term “smart contract” in the 1990s.
A white paper written by one or more developers using the pseudonym Satoshi Nakamoto laid out the blueprint for current blockchain technology in 2008. Nakamoto’s Bitcoin white paper cites Haber and Stornetta’s work and solves several issues that were preventing blockchain theory from becoming reality.
Nakamoto fulfilled the vision set out in the Bitcoin white paper by creating the first blockchain for Bitcoin in 2009. In 2014, Blockchain 2.0 was formed, allowing other potential uses for blockchain technology beyond cryptocurrency, such as smart contracts. Ethereum is a blockchain that was launched in 2015 that allows for smart contracts.
What can blockchain be used for?
While you may have only heard of blockchain in relation to cryptocurrency, like the Bitcoin blockchain, it can be used for much more than just Bitcoin transactions. This technology can be used by many industries to help them keep track of information in an efficient way. Here are examples of blockchain applications.
Cryptocurrency
The most widely known application of blockchain technology is digital currency. Bitcoin is not the only cryptocurrency that uses blockchain technology. Ethereum and Litecoin are also cryptocurrencies that use blockchain.
Without blockchain, cryptocurrencies would not be able to operate without a central authority. In the traditional financial world, transactions are typically approved by a middleman, such as a bank or credit card issuer. Cryptocurrency transactions are not approved or controlled by a central authority, but are verified by a network of computers.
Financial services
It’s no surprise that blockchain can be used in the financial services industry. Instead of monitoring a currency, financial service companies can use a blockchain to keep track of financial responsibilities such as bank guarantees and letters of credit.
Once something is recorded on the blockchain, it can’t be changed, which makes the blockchain useful for proving compliance. Blockchain technology can be used to transfer funds between financial institutions more quickly.
This document can also be used for creating contracts for things such as leasing or selling real estate. Blockchain technology provides a more efficient way to execute contracts and creates an unchangeable record of every transaction.
Healthcare
Blockchain has several uses in the healthcare industry. The blockchain can be used by different organizations to cross-check each other’s information and make sure that it is correct. An insurance company could use it to verify patient information rather than waiting for records to come in from a healthcare provider.
Blockchain technology can help to track medical supplies or medications through the entire supply chain from production to the end user, in case a recall needs to be made or to verify authenticity.
Voting
In theory, voting could be conducted using blockchain technology. Private keys could be issued to individuals to use for voting purposes. After voting, you can check the blockchain to ensure your vote was counted correctly.
A study by MIT and Harvard has found flaws in the concept of using blockchain for voting, despite the popularity of this idea. If voters were to lose their private keys, it would be impossible for them to vote. If someone gets access to someone else’s private keys, they could vote on their behalf.
Automotive industry
The automotive industry could also benefit from blockchain technology. The technology could securely share data about a vehicle with third-party owners and manufacturers. Auto insurers could use information that is stored on the blockchain to help them offer more accurate auto insurance rates. The data that would be used to help calculate these rates would come from your vehicle. Manufacturers could use the technology to track the parts that go into specific vehicles, allowing them to alert car owners of defective items. This would allow for a more efficient recall process as well as improve customer satisfaction.
Supply-chain management
The COVID-19 pandemic has highlighted the difficulties associated with managing a supply chain. Blockchain technology can be used to create an unchangeable record that can be shared by multiple parties along the supply chain. For example, Walmart Canada uses blockchain technology to manage invoices across its 70 third-party freight carriers. IBM created a blockchain-based system called the IBM Food Trust, which is designed to improve the food supply chain.
What are the benefits of blockchain?
To help answer this question, let’s take the example of Company ABC. Company ABC is a legacy business network that stores its data in multiple places and formats. The company’s transactions with its external partners must be easily validated for the company to be successful.
Most customers believe that blockchain technology will change their expectations of companies within the next five years.
– Salesforce, State of the Connected Customer, 2018
Problematic data reliability and accuracy due to out-of-date records, duplications, lost data, and errors were found by Joe Black, the company’s Chief Information Officer. These inefficiencies add costs through fees and delays. The situation also creates a lot of work for teams across the business through redundant and onerous paperwork. Reconciling data between ABC and its external partners has been a lengthy and difficult process. Joe is concerned that the situation could create opportunities for fraud and crime.
To resolve these issues, Joe decides to transition the company to a blockchain-based database or shared ledger. This brings together all the relevant data from the company’s parallel systems and databases, along with its partners’ data. Now all parties involved can have one integrated, interoperable source of truth. Now, every stakeholder has easy access to all of the data and information that relates to any specific business process.
Other benefits Joe and his colleagues start to see include:
- More robust security. Because data is secured using cutting-edge approaches such as cryptographic keys, blockchain networks are more resilient to data tampering and cyber attacks.
- Faster, cheaper transactions. Blockchain databases do not need traditional third parties such as banks and lawyers to authenticate transactions — that role is filled by the technology. By eliminating the need for intermediaries, businesses can streamline their processes and reduce costs.
- Greater transparency and traceability. Because every network member in a blockchain database has access to the entire database of transactions and their history, they benefit from real-time transaction-level assurance. Such systems can also be much easier to audit.
“The larger and more complex the data environment, the great the risk that something will go wrong.” Amber Baldet, CEO and co-founder of decentralized application development startup Clovyr, said that the more data lakes, or silos, we create, the more technical risk we create. The larger and more complex the data environment, the great the risk that something will go wrong. An ability to break down data into its component parts is very important in every industry at this point.
One source of truth that is integrated and interoperable is available for all parties involved. Now, every person with a stake in the business has instant access to data and information about any specific business process.
In practice, however, it is often difficult to achieve these benefits in practice.” A blockchain or distributed ledger can be used to connect different decentralized data stores, which can be interesting. However, it can be difficult to achieve these benefits in practice. Maybe it’s decentralized document signing within your organization, or across your own sub-legal entities. The idea is that you wouldn’t need to consult with multiple banks and lawyers before beginning a development process. This would streamline the process and make it quicker and easier to get started.
According to Scott Likens, a technology leader at PwC, blockchain will be a fundamental technology for preserving trust in the digital age. ” He is saying that it is very helpful to know that everything is in order when dealing with other businesses. This includes knowing that the paperwork is correct, the products are what was agreed upon, the payments are being made on time, and the people involved are who they say they are. By automating your transactions with partners and customers, you can free up time to do more with them.
How will blockchain disrupt industries?
Some of the most-cited use cases for blockchain involve the following sectors:
- Financial services. Many startups eager to disrupt traditional players deploy blockchain to develop applications that aim, for example, to cut out the number of intermediaries involved in existing transaction processes, such as stock exchanges, cross-border payment networks, and money transfer services.
“Their goal is to reduce complexity and cost. The Global Blockchain Business Council is focusing on developing blockchain solutions to counter fraud and ensure data integrity, according to CEO Sandra Ro. ” The event has been a shocking realization for banks and other financial institutions. As companies attempt to comprehend these advancements and their potential consequences, we are observing them invest in blockchain technology. The company is working to create teams specifically for this purpose, investing in external companies to create common initiatives, and taking precautions to reduce risk as much as possible.
- Healthcare. Healthcare startups are exploring ways to use blockchain to streamline the sharing of medical records in a secure way, protect sensitive data from hackers, and give patients more access to — and therefore control over — their information.
Companies are looking to create blockchain-based healthcare applications that would provide anonymous data pools for research companies and new methods to prevent counterfeit drugs.
- Food. Some organizations are exploring blockchain-based solutions that bring industries together using entirely new business models. IBM, for example, has set up a blockchain-based food safety initiative with Walmart that brings together growers, processors, distributors, and retailers.
The companies involved in this project hope that by creating a permanent, shared record of food-system data, it will be much easier and quicker to trace produce from farm to store. If this system is put in place, it will speed up investigations into contaminated food, while also allowing Walmart and its partners to more easily authenticate the food’s origin and learn about the conditions under which it was produced. An ecosystem that promotes transparency and accountability can help to build consumer trust.
Conn said that Salesforce expects to see more companies using blockchain technology to create a common data model that can improve value for customers. I think we’ll see lots of different groups of companies in different industries working together closely in the near future, with the customer always coming first.

According to Shira Rubinoff, a cybersecurity and blockchain advisor, if companies focus on specific use cases that are relevant to their business and their position in the market, they can decide if investing in blockchain technology is right for them or not. Companies need to have a clear understanding of the problem they are trying to solve in order to be successful.
