Advantages and Disadvantage of Blockchain

Blockchain is a cutting-edge database technology that powers almost all cryptocurrencies. Blockchain makes it incredibly difficult to hack or cheat the system by spreading identical copies of a database across an entire network. While cryptocurrency is now the most popular application for blockchain, the technology has the potential to serve a wide range of uses.

The benefits of Blockchain

Transactions are more accurate.
This can reduce mistakes because a blockchain transaction must be confirmed by many nodes. If one node has a database error, the others will notice the difference and catch the fault. In a traditional database, on the other hand, if someone makes a mistake, it is more likely to be accepted. Furthermore, each asset is uniquely identifiable and recorded on the blockchain ledger, eliminating the possibility of double-spending (like a person overdrawing their bank account, thereby spending money twice).

There isn’t any need for intermediaries.

Two parties in a transaction can use blockchain to confirm and finish a transaction without the need for a third party. This saves time and money by eliminating the need for an intermediary such as a bank. It has the potential to boost the efficiency of all digital commerce, to increase financial empowerment for the world’s unbanked or underbanked populations, and, as a result, to power a new generation of internet applications

Extra Protection

A decentralized network, such as blockchain, theoretically makes it nearly difficult for someone to commit fraud. They’d have to hack every node and modify every ledger to insert bogus transactions. While this isn’t impossible, many cryptocurrency blockchain systems use proof-of-stake or proof-of-work transaction verification procedures that make adding fraudulent transactions difficult, as well as not in the best interests of participants.

Transfers that are more efficient

People can execute more efficient financial and asset transactions, especially globally, because blockchains function 24 hours a day, seven days a week. They don’t have to wait days for a bank or government agency to confirm everything manually.


Blockchain’s Disadvantages

Transactions per Second Limit

The speed at which blockchain can move is limited because it relies on a wider network to authorize transactions. Bitcoin, for example, can only handle 4.6 transactions per second compared to 1,700 transactions per second for Visa. Furthermore, as the volume of transactions grows, network speed concerns may arise. Scalability will be difficult until this improves.

Costs of Energy are Expensive

It costs substantially more electricity to have all of the nodes validate transactions than it does to have a single database or spreadsheet. This not only raises the cost of blockchain transactions but also adds to the environment’s carbon footprint. As a result, several industry leaders are starting to abandon some blockchain technology, such as Bitcoin: Elon Musk, for example, recently announced that Tesla will no longer take Bitcoin, citing environmental concerns as one of the reasons.

Possibility of Asset Loss

Cryptographic keys are used to secure some digital assets, such as cryptocurrencies in a blockchain wallet. This key must be properly guarded. Currently, there is no mechanism to recover a digital asset if the owner loses the private cryptographic key that provides them access to their asset—the asset is gone forever,” Gray explains. Because the system is decentralized, you won’t be able to contact a centralized authority, like your bank, to request access.

Possibility of Illegal Activity

The decentralization of blockchain gives additional anonymity and confidentiality, which makes it tempting to criminals. Illicit transactions on the blockchain are more difficult to track than bank transactions that are linked to a person’s name.


What is the Best Way to Invest in Blockchain?

Because blockchain is only a system for storing and processing transactions, you can’t actually invest in it. You can, however, use this technology to invest in assets and businesses. The simplest solution is to buy cryptocurrencies like Bitcoin, Ethereum, and other blockchain-based tokens. Another alternative is to invest in firms that use blockchain technology. Santander Bank, for example, is experimenting with blockchain-based financial products, and you might buy their stock to obtain exposure to blockchain technology in your portfolio. For a more diversified strategy, consider investing in a blockchain-related exchange-traded fund (ETF), such as the Amplify Transformational Data Sharing ETF (BLOK), which invests at least 80% of its assets in blockchain-related companies.
