Growing Demand for Software Engineers in Blockchain Technology

Blockchain technology makes use of a centralized, peer-to-peer (P2P) network of databases, also called nodes, to validate and record digital transactions between individual users located anywhere across the globe. These transactions often take place through the exchange of cryptocurrencies such as bitcoins.
The craze for blockchain technology stems from its hack-proof architecture which renders all user transactions transparent, authentic, and authorized. Each node updates its database in real-time as and when transactions occur. The transaction gets authorized only when a majority of the nodes in the network validate the transaction.

Once the verification is complete, a block, consisting of hash and keys, is generated for each new transaction and is linked to previous transactions in every database. Every node updates its database with the new block. A hacker would have to break down every node in the system to commit fraud. Since the nodes are located globally and all the transactions are visible to every user, it is impossible to commit fraud for a digital transaction implementing blockchain technology.

Industrial Applications of Blockchain Technology:


Financial service demands high security and hackproof technologies. Blockchain fits right in. Cryptocurrencies will allow users to become bankers themselves, lending, borrowing, and exchanging money over a centralized, transparent, and secure framework. The currencies are not regulated by any central agencies. Blockchain technology eliminates the need of a middleman, decreasing chances of hacking, identity theft, and fraud. Every transaction can be digitally stored and verified. Since every transaction is verified, implementation of blockchain in financial institutions and Fintech companies can curb illegal activities such as money laundering.

Cybersecurity attacks and data breaches have been a cause of major concern for individuals. Often hackers steal sensitive information of users such as a PAN/Aadhar number to use it for fraudulent transactions. However, blockchain as mentioned above securely authenticates and authorizes the identity of a user without needing any sort of sensitive information. Even the user’s name is not required. Blockchain could play a major role in maintaining cybersecurity of digital transactions in the future.

Charity in the form of food, clothes, cash, vouchers etc. is vulnerable because they can be stolen. In many cases, it does not reach the intended recipients due to a corrupt administration. Blockchain technology can be implemented to keep an end-to-end digital flow of donated material from the donor to the recipient. The United Nations implemented an iris-based blockchain system in refugee camps in Jordan. Refugees pay for their purchases in supermarkets through iris scanning, which is then recorded in a blockchain platform. The UN gets full access to these transactions and is able to verify the identity of the person and ensures that the food reaches the intended people. This eliminates the need for the UN to deliver cash, vouchers, and supplies through middlemen.

Deploying blockchain technologies in this sector can help verify the academic credentials of a student in a secure manner. Transcripts and related material could be uploaded to an online system which uses blockchain technology. Since it is centrally deployed it is accessible to all concerned party and is easily verifiable. Every modification is recorded and linked to a previous entry. Thus, a student cannot record incorrect/fraudulent data of unearned degrees since it will not pass the blockchain verification processes.

Medical records

This is an industry where blockchain can radically transform lives. If patient data is uploaded to a centralized server, doctors can access their patient’s real-time medical condition to make the most appropriate diagnoses. This allows timely, efficient, and cost-effective treatment saving lives. It can also help protect the medical records of patients.

Frequently Asked Questions (FAQs)

1What do you think sets blockchain technology apart from other technologies?

Blockchain technology, in my opinion, is unique in that it enables for safe, transparent, and tamper-proof transaction recording. It also allows the production of digital assets that can be transferred between parties without the use of a third-party intermediary. This mix of characteristics distinguishes blockchain technology from other technologies. Many industries, including finance, healthcare, and logistics, could be transformed by it.

2What do you think are the future applications of blockchain technology?

Blockchain technology has a wide range of possible uses. Each of these apps has the potential to change the way we interact with our surroundings. Secure online voting, for example, could assist improve voter turnout by making it easier and more convenient for people to vote. Peer-to-peer payments and distributed cloud storage could make it easier for users to exchange and access information. Smart contracts could help firms save time and money by streamlining the contract-signing process. Apart from these benefits, blockchain can make social media apps fully trustless because no single person will have authority over the entire system.

3How is a blockchain maintained?

A blockchain is a distributed ledger that is maintained by a group of computers linked to the network. Nodes are the machines that make up the network. Nodes that are accepted by the majority of the network add new blocks to the blockchain. The nodes that maintain the blockchain are paid with money for their work. To add a new block to the blockchain, the user must pay a modest fee. Maintaining a blockchain is an essential step in ensuring that it remains functioning and safe. Updating, monitoring, troubleshooting, repairing, and optimizing the blockchain are all part of the maintenance process. Securing the blockchain is also an important step in ensuring its safety and security.
