Big Data and Getting A Job As A Blockchain Engineer


Are you interested in learning more about a rewarding new career in the rapidly growing field of blockchain technology? In the last decade, digital cryptocurrencies have generated incredible hype around the revolutionary technology known as blockchain. After the pseudonym Satoshi Nakamoto was used to introduce Bitcoin in 2009, it became a household name. Since then, the blockchain has grown into a fantastic technology, piqued the curiosity of an ever-increasing number of people.

People who are unfamiliar with blockchain are more likely to confuse it with the cryptocurrency Bitcoin. However, the general public first learned about blockchain technology through the use of Bitcoin. In today's digital world, blockchain technology is finding a wide range of applications. To use the blockchain, you don't need to understand how it works, just as you don't need to understand how a car gets its power. If you're interested in a career in blockchain technology, learning about the technology and getting a handle on its fundamentals is a good idea.

Is Blockchain Technology Really What It Sounds Like?

Bitcoin, the first cryptocurrency based on Blockchain technology, was created 10 years ago. For the first time, a blockchain solution was successfully integrated and put into action. According to It's a digital ledger or distributed database that keeps track of transactions and can be accessed by anyone," says Mr. Alex of the Blockchain Research Institute who wrote the book Blockchain Revolution 2016. should be set up to keep track of more than just financial transactions.

To put it another way, Blockchain is a distributed, encrypted database that keeps track of all of the exchanges, transactions, contracts, and so on. A key feature of Blockchain is that it's an automated record that can be accessed from a large number of computers. As a result, Blockchain can be used on a wide range of computer systems and does not require a single location. Incorporating digital currency like Bitcoin, smart contracts, and other cutting-edge and revolutionary applications, the blockchain is already having a significant impact on the financial and technological sectors.

A bank or government agency is not required when transferring property, money, contracts, or other valuables via the blockchain. It is impossible to alter information once it has been recorded in a blockchain because of its inherent stability.

Centralized organizations typically do not have access to any information stored in a blockchain. When users can access and conduct transactions without the involvement of a third party, blockchain technology becomes a valuable economic tool. During these kinds of transactions, the security of user data is ensured by encryption. It is rare for a data breach to occur when using blockchain technology, which is a major advantage.

Why Is Blockchain Technology So Popular?

There are a lot of claims about the true potential of Blockchain. It's been hailed as the next big thing, and many people have put their reputations and fortunes on it. For example, claims have been made that it can help improve transparency in the healthcare and manufacturing sectors, and that it can help reduce fraud in enterprise applications such as financial systems. The use of blockchain technology could reduce the need for centralized control in a thriving sharing economy.

The immutability and simplicity with which it makes data exchange possible are two of blockchain's greatest assets. With the potential of smart contracts and new business models in Blockchain, it is time for businesses to rethink their fundamentals. Every industry can benefit from blockchain technology because of its many trust-building and privacy-protecting features. It's likely that blockchain technology will be a hot topic for years to come.

Healthcare Blockchain

More blockchain projects have been launched in the healthcare industry than in any other, with a 25 percent increase in activity compared to the next most active sector (financial inclusion at 13 percent). To store and exchange digital health records, for example, healthcare organizations can use blockchain infrastructure. This provides a more decentralized and safe solution. The healthcare industry could save up to $100-150 billion per year by 2025 if blockchain technology is adopted, according to a report by BIS Research. Individuals would greatly benefit from lower costs and more secure management of their private health information.

As the National Center for Biotechnology Information (NCBI) explains, Blockchain technology allows patients to designate access rules for their medical data, allowing specific researchers to access parts of their data for a set period of time. Patients can also connect to other hospitals and automatically collect their medical data using blockchain technology. As part of their training, students learn how to use the blockchain to automate a company's health insurance process and build a network of patients who can enroll in the company's health insurance plan.

Supply Chain Management Using Blockchain

Put yourself in the position of purchasing apples from an internet retailer. As a result, when you open the box to find the apples, you discover that most of them have already gone bad. There's not much you can do about it if the store doesn't offer refunds, is there?

Isn't it possible that this could have been avoided?

With blockchain technology, such issues can be avoided because it allows for traceability to be maintained throughout the entire supply chain. It is possible to use blockchain technology to securely and transparently track all types of transactions.

Transparency, verification, and permanent record-keeping are just a few of the benefits that blockchain brings to supply chain management. Anyone can verify the product's authenticity or status using this method.

A blockchain distributed ledger is being built by Walmart to connect and track pork suppliers, shippers, purchasers, and others who are involved in delivering the food product throughout China. There is less risk of data tampering or inaccuracies here because of the use of blockchain.

Cybersecurity Using The Blockchain

In this scenario, person A sends 20 dollars to person B. The transaction details are stored in the cloud once the transaction begins from A's end. Hackers can now steal money from the cloud because of the availability of the data. As a result of the internet's centralized network, it is vulnerable to cyberattacks and data theft.

What would be the differences if everything was done on the blockchain?

Consider how this transaction would work if it were done using blockchain technology.

When A sends 20 dollars to B, he does so in the form of 0.0025 bitcoin or BTC. For the first time, this transaction will be recorded in a blockchain. In this case, each node has a copy of the ledger (data), and cryptography ensures that transactions are immutable.

Attempting to hack into the blockchain would be futile now. Because of the peer-to-peer nature of blockchain connections, malicious attacks are difficult to launch.

Look at a real-world use case for this blockchain technology. The blockchain is being utilized by Mastercard to facilitate the transfer of funds. In addition, it enables the currency to be exchanged without the need for a central authority.

Voting is the next blockchain use case we'll examine.

Voting On The Blockchain

Let's take a look at how the voting is going right now. Using a centralized Electronic Voting Machine (EVM), a voter casts a ballot for their preferred candidate. Centralized systems make it easy to hack EVMs and manipulate the vote count. Even so, a blockchain-enabled, decentralized system may one day make it possible to eliminate this vulnerability and guarantee free and open electives.

Let's take a look at what voting would be like if blockchain were used.

The first step is for the voter to download a voting app like MiVote. The next step is for the user to register for the election by providing their voter ID. Once the user has been authenticated, they can cast their vote without disclosing their identity to the public. It's impossible to remove a vote from the blockchain once it's been recorded. Officials can count votes with confidence because each voter identification number corresponds to a single ballot. As an additional benefit, blockchain allows voters to keep track of their ballots, as well.

A blockchain-based voting system has the potential to provide complete transparency by eliminating the need for any third-party systems. 

Benefits Of Using Blockchain Technology

Several excellent features support the advantages of blockchain over a conventional financial institution. These are some examples:

  • Unveiling a publicly accessible ledger : Anyone can use this, even if they've only ever used the blockchain once. In other words, they have unlimited access to all of the data stored in the blockchain, regardless of when it was created or when it was completed. 
  • A block's changes are irreversible: The Genesis Block is the first one. Immutable blocks are those that cannot be changed. It is impossible to undo any change, no matter how significant or insignificant it may seem at the time. Total accountability is ensured by this method. 
  • There is no centralized authority: Because of this and the fact that the ledger is distributed, no one can alter the ledger. The majority of the network members must agree to any changes before they can be implemented. Because of this, consensus algorithms do exist.
  • Money isn't the only asset that can exist: A block can safely house a variety of items, including vehicles, property, machinery, and more.
  • A very high level of obscurity: All transactions in a block are subject to this check, which is perhaps the most important one of them all Sender's private key contains the sender's and receiver's private information, as well as the transaction information and the SHA256 encryption algorithm in this instance. The private key is encrypted and transmitted across the world, verified and accepted by the miners, and then added to the block.
  • The proof of the pudding is in the eating: The previous hash, transaction details, a nonce, and a hash are the four elements of each transaction in a block.
    • A nonce is a random number that is used to generate a hash number that is unique. The miners must know a lot about generating computations because it takes a lot of computational power every time the nonce is changed.
    • A hash is a hex value that contains both numbers and letters. The new hash will be completely different if the nonce, transaction details, or the previous hash are changed in any way. When someone tries to change the hashes of every entry in a block and the entire blockchain, it would be nearly impossible to do so successfully. Imagine the amount of time and computing power it would take to accomplish this task!
    • Proof of work is a process in which a number of miners around the world work together to find the best nonce value that meets certain predefined conditions for the hash value, which must be less than the target set by the network in order to satisfy a block.
  • Mining: Miners receive cryptocurrency when they are the first to discover an appropriate nonce value, thanks to this process. At the time of writing, 12.5 Bitcoins is the current value. Amount is, however, constantly shifting. It was initially 25. As of now, it is 6.25. In the end, it all comes down to how many cryptocurrencies there are in the blockchain. There is a decrease in reward as the number decreases. An additional 12.5 Bitcoins are awarded to miners for the last transaction to be recorded in each block. New Bitcoins can only be created this way. This also applies to new forms of other cryptocurrencies. 

Potential Uses Of Blockchain Technology

In the future, public blockchain applications could make our lives simpler and more secure. Here are a few examples of blockchain's current and promising uses:

  1. Invoices and Cash Payments
    In a matter of seconds, money can be sent from one person to another using the blockchain. 
  2. Maintaining an Eye on the Supply Chain
    For the benefit of both businesses and consumers, we can conduct thorough supply chain audits with blockchain.
  3. Loyalty Programs for Retailers
    Shoppers and merchants alike benefit from loyalty programs in the retail industry. Tokens could be used to create a reward-based program for customers in a store using blockchain technology. 
  4. Copyright and Royalty Protection
    The reallocation and transfer times of digital assets could be recorded and logged with the help of the blockchain. It is possible to legally acquire copyrights, and content owners will receive their fair share.
  5. Electoral Systems that use the Internet
    Electors could cast their ballots electronically and have the results reliably preserved using the blockchain. Because of its widespread network presence, regulators can quickly identify any fraudulent activity. 
  6. Keeping your data safe is essential.
    Despite the fact that cloud storage devices can be used to back up data, they are also prone to hacking. Blockchain technology, if properly implemented, could eliminate the risk of a data breach.
  7. Trade in Equity
    Equities trading takes too long under the current system. Transactions such as completions and confirmations can be completed in a fraction of the time using blockchain technology.
  8. Records of a medical nature
    Concerns about the leakage of patient records from digital storage have risen. Using blockchain technology, you can protect your data while making it accessible to others.
  9. Weapons Traceability
    In order to keep track of who owns what weapons, a government could use a registry network built on the blockchain to keep track of who sold them.
  10. Transfer of Ownership

    A blockchain-based ledger could be used to record and store all relevant information about the sale of real estate such as land and buildings. Even data from the past can be retrieved and entered into the blockchain database retroactively.
