Issues & Limitations Concerning Blockchain Technologies


Issues & Limitations Concerning Blockchain

As good as it can be, the blockchain technologies, like all other technological revolution, presents its own set of risks.

Some people who have tried the blockchain technologies before have claimed that it is somehow overhyped, when in fact, it still has its own limitations that may not make it an ideal option for many digital interactions.

But thanks to hours and hours of research and development that went through a lot of success and failure, and trial and error, we finally get to understand the current issues and limitations of blockchain and were able to come up with solutions for them.

Complexity

Blockchain technologies since it is relatively new is an extremely complicated subject. It presents a new set of new vocabulary that many people might find it hard to understand.

Since blockchain involves cryptography, which is a completely unknown field to most people, it’s no surprise that not everyone is able to fully understand the concept behind it. Not to mention that cryptography brings a big package full of jargon. Thankfully though, there are now glossaries and indexes that provide interesting and easy-to-understand information about blockchain technologies and its related topics.

Network Size

Blockchains like other distributed systems are not fully protected against malicious actors. They are, however, more respondent to attacks and grows stronger as more time passes on.

But for that to be possible, a blockchain must have a huge network of users. If the blockchain has not enough network of users, it is more difficult to enjoy the benefits it may bring.

Human Error

If a blockchain is used as a database, the information going into it must be of high quality and of high integrity. The data stored inside a blockchain is not basically trustworthy at first, which is why all the transactions and events must be tracked accurately before it is stored.

Unavoidable Security Flaw

There is an inevitable security flaw that concerns most users about blockchains: if the majority of the computers that act as nodes in the network tell a lie, that lie can become the truth. This is commonly called as “51% attack” and pointed out by Satoshi Nakamoto back when he launched bitcoin.

This is why all bitcoin mining activities are closely monitored by the community to ensure that no one will take advantage of this security flaw.

Politics

Since blockchains provide an opportunity for governments to digitize their system, and because miners are basically creating a new form of incentivized governance model, various kinds of public disagreements between involved parties have aroused.

These disagreements are a common feature of the blockchain industry which is clearly expressed in the event of “forking a blockchain”. This is a process where a blockchains protocol is updated once the majority of the users within that blockchain have agreed to it.

These arguments can be very technical which can result in heated conflicts between the involved parties. They can, however, provide a good insight especially to those people who are interested in a new type of governance model that the blockchain technology brings to the table.
