Blockchain Technology Will Revamp the Future of Transactions

Blockchain technology-based applications find wide use in nearly all industry segments. One of the most beneficial applications of blockchain is in recording, retrieving, and settlement of transactions of any nature. A vital but time-consuming task of any business is recording transactions. Traditionally done by staff on Excel spreadsheets, it is highly prone to errors. A single error in records can paralyze the entire system and have far-reaching implications. Blockchain technology’s consensus mechanism and encryption features can minimize human errors. Since all blocks in a blockchain are linked chronologically, it’s possible to trace the origin of an erroneous transaction. Naturally, the system is more error-free and reliable.

The distributed ledger system deployed by blockchains increases its transparency and accountability. The append-only structure of blockchains allows data and transactions to be added to the chain, but prohibits deletion or modification of existing transactions in the chain. This feature allows tracking back of transactions to the genesis block where a transaction originated. Another advantage of blockchain technology is the ease and speed of settlements that it offers. Owing to all these advantages, blockchain technology is poised to revamp the future of transactions in a big way.

Fundamentals of Blockchain Technology

To understand the implication of blockchain technology on future of transactions, we need to understand some basics of this transformative technology:

  • Open source and distributed

Blockchains are made of blocks of transactions linked together in a chronological sequence. Copies of the ledger exist on each node in the blockchain. Anybody can view and access a blockchain but addition of a transaction to the blockchain will require consensus of all miners in the system.

  • Immutable and Encrypted

As explained before, blockchains have append-only mechanism. Data once added to a blockchain is immutable. Since all blocks are inter-connected, a change in one transaction in one block, will impact all connected blocks and alert all nodes in the blockchain. For this reason, blockchains are perceived as highly secure. Another security feature is its encryption mechanism. Though a blockchain is open-source and visible to all, the data within is in encrypted form. To decipher it is nearly impossible without proper credentials of a legitimate miner. Hence, blockchains are less exposed to hack attacks to a greater degree than other mediums.

  • Consensus and Reward System

    Consensus and Reward System

To maintain the integrity and functionality of a blockchain, a consensus and rewarding mechanism is followed. When a transaction originated in a blockchain, all miners in the chain start verifying it by solving complex mathematical puzzles using super-powered computers. Once a puzzle is solved by a miner, his solution is verified by other miners. When they reach a consensus, the transaction, along with its solution, is bundled into a block and added to the blockchain. The miner is rewarded by Bitcoins or altcoins (in virtual currency-based blockchains) for his efforts. The other miners start looking for other pending transactions and the blockchain keeps growing.

  • Multiple Connected Blockchains

Multiple Connected Blockchains

A common myth is that there exists a single blockchain in which all transactions are added. This is not true. There are multiple blockchains in the system. They can exist independently or be connected to one another. The blockchain ecosystem is like the internet in this sense. But a fundamental difference between blockhains and internet is that the blockchains are not connected to a central server or hub. Each node in a blockchain is like a server and harbors copies of the distributed ledger of that blockchain.

 

How Blockchain Technology Will Impact Transactions

Here’s how blockchain technology will make transactions speedy, immutable and efficient, bringing in a new found demand for Blockchain App Development Companies:

1. Increased Transparency and Security of Data

The way in which businesses and organizations store data will undergo drastic changes by the use of blockchain technology. Presently, record-keeping is a cumbersome task that requires dedicated staff and incurs huge overheads. It’s also prone to human errors and physical hazards such as fires and thefts. Blockchains are virtual distributed ledgers, free from of all these shortcomings. Transactions are encrypted, immutable, and stored in an orderly fashion. They are accessible to all nodes but cannot be altered.

2. Elimination of Intermediaries

Blockchain transactions are not mediated by third-party intermediaries. They are verified by miners who work round-the-clock in solving mathematical puzzles. As soon as these computations are done, the transaction is verified and added to the distributed ledger. The change is reflected throughout the blockchain. There is no need for lengthy documentation or hefty verification charges. The reward for miners is nominal and isn’t a burden on parties involved in a transaction. Elimination of intermediaries reduces transaction costs and speeds up the process.

3. Efficiency in Settlements

Traditionally, it took days or weeks for settlement of transactions. For example, you might purchase a two-wheeler but registration of its ownership can take months. In blockchain technology, settlements are done instantly and this is perhaps, its biggest advantage. As there are no intermediaries and all verification is logic-based, human involvement is minimal and so are processing delays.

Challenges before Blockchain Technology Adoption in Transactions

Just like there are two sides to every coin, blockchain technology also has some drawbacks. Since the technology is in formative stages, evolution is natural and necessary. Enthusiasts claim blockchain technology will overcome roadblocks and create a disruption such as the one by internet, decades back.

  • Centralization of blockchains

    Centralization of blockchains

Private blockchains beat the very essence of anonymity and decentralization. Banks and private organizations have generated their own blockchains and control the private keys and right to admission. While this enhances security of transactions further, it defeats the very purpose of having a decentralized ledger system.

  • High Operational Costs

The total cost of maintaining the Bitcoin ledger is approximately $600 million. As the blockchain size increase, the cost will also increase. Moreover, the operational and set-up cost of mining rigs is not small by any standards. Addition of more miners in the system constantly ups the competition. So, there is no guarantee of rewards despite paying heftily for participating in the system.

In a race to validate transactions, each node in the chain works overtime and ends up consuming a huge amount of electrical energy. If the cumulative cost of energy consumption and labor is considered, blockchain technologies might turn out to be a financial liability for businesses.

While this was about the operational cost, the Cost to develop Blockchain App also has a similar story to tell. Since the technology is fairly new in the industry, the technical expertise needed to develop a Blockchain app is still not widespread, which tends to increse the cost of development.

  • Lack of Understanding and Coordination

Another roadblock is a lack of awareness about how blockchains work. Apart from banking and finance sectors, not many industry folks understand blockchains. This discourages them from exploring use cases for their own transactions.

For blockchain technology to bring any real benefit, there needs to be coordination between industries and organizations. But the reality is far from it. Organizations are developing their own blockchains to cater to their own applications.

  • Absence of a Regulatory Body

While decentralization of blockchain is a definite plus, there is a compelling need to have a regulatory body to exercise oversight. In the absence of regulations, impact of any negative activities in a blockchain can affect participants directly and hamper transactions from start to finish. Regulation is also important for controlling the size and costs of blockchains.

Blockchain technology indeed has a huge potential where transactions are involved. But to leverage this capability, further exploration and maturation needs to take place.
