Blockchain For Dummies: How To Understand This New Technology
New technology has impacted the banking industry and has made significant changes in the way people invest. Traditionally, investing in the stock market has been the greatest source of income generation.
The advent of cryptocurrencies in the market has created new ways to invest, as people realize moving away from the traditional investing mindset is quite lucrative. However, potential investors are put off by the seemingly complex technology that is the backbone of the cryptocurrency boom. This gives rise to a few crucial questions. What is blockchain technology? What makes it so powerful? Why is it considered disruptive?
The principle behind its functionality is quite simple. At New Kind of Network, interconnectivity is key. Read about our partners here. At its core, blockchain technology is the digital, decentralized record-keeper that tracks and saves all transactions.
As opposed to the traditional method of copying data from a central source, blockchain distributes it. Every block of data is independently secured and bound to each other using cryptographic principles, forming a chain of blocks, i.
Blockchain technology is an ingenious method of transferring data securely from one point to another. Blocks of data are verified by thousands even millions of computer systems across the network. This eliminates the requirement of a central validation authority.
Verified blocks are then added to the chain, which is stored on the network, creating blocks with a unique record and history. Blocks are typically used to record transaction details, but the principle can be applied across several industries. Blocks store information like date, time, and amount of transactions. They also store a record of every entity involved in the transaction. Instead of real names, purchases are recorded without identifying information, but rather using unique digital signatures.
Blocks also store identifying information about themselves that helps networks differentiate between two blocks. Even similar or repeated transactions have different codes when stored on blocks, which distinguishes each transaction from the previous one. In order to combat the pervading incompetence of the traditional banking sector, Satoshi Nakamoto created Bitcoin , the most popular cryptocurrency in the world.
Although the concept of blockchain has been around since , Satoshi implemented the concept practically in His real identity remains a mystery to this day, which only increased public fascination with Bitcoin and blockchain technology. Curiosity surrounding blockchain technology led to a burst in investment.
As a result, IT companies around the world began applying the principles of blockchain to other IT projects. The value of blockchain technology comes from its core tenets. The technology works on three basic principles:. The sheer security offered by blockchain technology is what makes it unique. The blockchain process is initiated when a transaction is completed.
The user picks out a product they like, and proceed to the checkout page. They then finish the purchase by paying through a secure payment gateway. The transaction details are then verified and entered into blocks. In the case of other traditional establishments, there is a central authority, a council or a department that verifies the authenticity of the transaction being conducted by the user. In the case of blockchain, this task is left to numerous independent systems owned by different people on the blockchain network.
Details like the parties involved, in this case, the user and the eCommerce store, the time of the transaction, the amount paid, the product purchased are recorded. When the details are corroborated and verified to be true, the block gets green-lit. When a party exchanges currency, a bank or another central institution takes precedence.
The central entity takes control and defines the term of the transaction. This principle translates across domains as well. Human history has been dominated by central authorities making decisions and governing over people.
The policies and rules imposed by such authorities are not always transparent. The reason blockchain is considered an industry-disruptor is because it takes away the very idea of a central authority — shaking the very roots of established norms. A decentralized system with several computers acting as control nodes gives all involved participants equal power — as opposed to one single authority enjoying full control.
Digital signatures for the user and store are generated to protect real-life identities. The bloc is then inserted into a chain with similar blocks. The other blocks can number from hundreds to possibly thousands. The block then receives a unique hash that can be used as an identifier. The fact that user information is stored across several computers is a privacy concern. Blockchain users can rest easy because every piece of information is encrypted.
Anonymity is maintained by making transaction details untraceable by using cryptography methods. Cryptography is a central part of blockchain technology. Since copies of unique blocks are spread of thousands to million systems, manipulating or deleting data is a mammoth task, one that is almost virtually impossible to pull off without detection.
The linear and chronological arrangement of blocks in a chain means that going back to add new blocks or altering existing ones is impossible.
New blocks are always added at the end of an existing chain. If a hacker wants to access this transaction for whatever reason, they cannot actually hack the block without changing the associated block.
As soon the dollar amount of the specific transaction is edited by the hacker, it automatically changes the cryptographic hash associated with the block, and generates a new block with a new hash. In order for the hacker to cover their tracks, they will need to edit the old hash. But this will result in the generation of a new one again, and the cycle repeats. The generated ledgers are indisputably true and cannot be removed or altered.
Imagine a single excel spreadsheet that is replicated across a network of thousands of computers. The network is set up to change the spreadsheet cells and update all changes across every computer. In the process, it always records which system made the change along with the timestamp. This is a very basic understanding of the functioning of blockchain technology. Ready to learn more about New Kind of Network? Read our story here. Blockchain is, however, technologically mature with over 10 years of use.
The benefits of blockchain are its very cornerstones — transparency, immutability, security, and decentralization. When investing in blockchain technology , companies can expect to leverage benefits like these. First and foremost, the information ledgers are distributed in equal capacity among all nodes of the network. This distribution creates security, decentralization, and massive accountability. The ledgers are also timestamped and added chronologically, which makes tampering with the chain information close to impossible.
Blockchain technology also allows for independent verification without relying on unsecure third-party vendors. Every transaction and piece of data are attached to blocks after a process of maximum trust verification. A consensus among every participant of the ledger chain must be reached to add that transaction to that particular block. This exponentially increases the trust value attached to each block.
Lost data can always be recovered easily, as the probability of losing the same piece of data across millions of participant nodes attached to different internet providers and servers simultaneously is virtually zero. The transactions are also transparent. Individuals in the network who have a good reputation in the community , and are widely trusted, are given authority over the overseeing transaction details. Origin details, edit details, and transaction specifics can always be traced to the source of creation.
Consensus protocols and policies are enforced to prevent duplication or other fraud. Stability is another advantage of blockchain technology , owing to the immutability of information ledgers. The strength of blockchain technology stems from the independent nodes across the network.
While this is improbable, it is definitely possible. This leads to the complete compromise of the blockchain system. The technology is still immature and the predictability of these factors grows smaller with the increase in size. While the immutability factor of being unable to modify data is a boon is most cases, it can serve to hinder as well.
Several industries require constant modification of data across networks, and blockchain does not offer an easy solution to do this. In cases of a wrong entry, or shift in processes, the old chain has to be abandoned for a new one. In addition to this, some mainstream blockchain technology e. It also requires massive amounts of data storage as it scales up. The primary application of blockchain technology has been in the financial sector.
The application of this principle can be carried over to several industries and has the potential to disrupt the functioning of traditional institutes as we know them. The primary industry to be impacted by blockchain technology is of course, the banking sector. Blockchain technology provides a comprehensive solution to most banking issues, by providing an unalterable ledger of every transaction conducted. Secure records lower the risk associated with online banking, and the decentralized nature of blockchain can help reduce the costs of transactions.
