Some Prominent Drawbacks of Blockchain Technology

Drawbacks of Blockchain Technology

Do you really want to learn about the drawbacks of blockchain innovation?  If yes, you’ve come to the correct place.  Let us get started! If you track the blockchain innovation sector, you will notice a pattern of favorable blockchain publications as well as information. Practically every publication promotes the word to increase blockchain acceptance among corporate users, students, and programmers. However, this is simply one aspect of blockchain innovation.  It, like every other technology, has its own set of shortcomings, i.e., drawbacks. The tendencies, on the other hand, are not negligible. As the need for blockchain skills grows, businesses are seeking qualified candidates. In this post, we will look at such drawbacks and get a better understanding of blockchain technology.

What is Blockchain?

Blockchain is a shared ledger innovation that, in many ways, enhances centralized-based approaches. It comprises peers linked in a shared database, each with a replica of the ledger.  The network employs a consensus technique to verify the transfers between users.

Blockchain Technology’s Drawbacks

Below are some of the prominent drawbacks of Blockchain technology:

  • No Data Alteration

One of the prominent Blockchain’s key advantages is that it makes data modification difficult. Sad to mention, but it’s obviously one of the major drawbacks. If inaccurate information is entered on the log, it is tough to change or erase it. There might be some justifications why data must be changed, but a shared ledger could make this practice difficult.

One method to address to this issue is to do a blockchain hard fork. It necessitates the abandonment of the old chain in favor of the latest one with the correct data. On the other hand, a hard fork might cause a network split in which some users stay on the older chain.  Sadly, such a circumstance can’t always be prevented, making this choice less appealing.

  • Management of Private Keys

As previously stated, the personal key is a critical piece of data for anybody utilizing a blockchain system.  The personal key is a unique identifier that corresponds to the possession of bitcoin or other information kept on the blockchain network. A consumer wouldn’t be able to acquire that data again if the private key isn’t there. This increases the importance of consumers storing this data safely, which creates another issue in terms of comfort.

In the context of blockchain innovation, recovering a personal key is impossible. It can only be created once and is generally given to the customer once. If they end up losing accessibility, a serious issue arises that is very difficult to resolve. The use of private keys is still one of the limitations of blockchain innovation nowadays, but it is a necessary component of exploring this sector.

  • Inefficient

Blockchains, particularly those based on PoW, is extremely inefficient. Because mining is an extremely competitive industry with only one victor every 9 minutes, the efforts of the remaining miners are squandered. Because miners are constantly attempting to boost their computing resources to have a better possibility of getting a verified block hash, the Bitcoin platform’s resources have risen considerably in recent years. It now requires more power than some other countries, including Iceland, Finland, and Nigeria.

  • Certain Blockchain Solutions Require Excessive Energy

Bitcoin was the first to use blockchain technology. It employs the Proof-of-Work consensus method, which relies on miners to perform the heavy lifting. Miners are rewarded by solving challenging mathematical puzzles. The high-power consumption of these difficult mathematical equations renders them unsuitable for use in the actual world.

When the database is refreshed with the latest transaction, the miners must address the issues, which requires a significant amount of energy. Unfortunately, not all blockchain systems function in the same way. Other consensus methods have already overcome the issue. An authorization or limited network, for instance, doesn’t have such issues because the quantity of nodes inside the network is fixed. Furthermore, since global consensus is not required, they employ efficient consensus mechanisms to establish an agreement. However, when it comes to the most prominent blockchain system, Bitcoin, there is still an issue that has to be fixed. To summarize, permissioned systems effectively reduce energy consumption, but public networks might take a significant amount of energy to stay functional.
