Now days Blockchain is one of fastest growing field. Despite a large number of supporters supporting this technology, we still have the drawbacks which need to be addressed. In this article I am going to threw some light on few important challenges in Blockchain.

Below are five key challenges in Blockchain.

Big Initial Cost:

As Blockchain is a new technology, you need to invest in this new technology for gaining knowledge for your team, development, testing and till production environment. It involves more cost at initial phase. The organisations need to spend a lot of budget in training, setting up the infrastructure and other areas of cost, thus it makes a costly affair for Blockchain.

2. Huge Energy Consumption:

Energy consumption is huge in case of public Blockchain. A rise in the number of crypto asset users, traders and investors translate into an increasing demand for crypto mining. It leads into an energy-intensive procedure that consumes a significant amount of electricity.

As per the whitepaper published in June 2017, the energy consumers in Bitcoin network can be used by 700 average American houses. With such a large consumption of energy, it becomes mandatory to come up with an alternative consensus mechanism that could consume less power.

3. Privacy & Security:

If a Blockchain is public, every transaction ever recorded on the Blockchain is available for anyone to look at. As you are not directly recognized on network, there is relatively low risk. Yet there are many privacy policies which are having robust requirement, which Blockchain is not able to fulfill due to distributed database. Even your wallet in local browser can be hacked and there is still privacy issues.

Many hackers are and must be hunting for processing power to “mine” for coins (aka crypto-jacking) and target large enterprises with big computational energy. Apart from it, small early stage Blockchains tend to be especially vulnerable to attacks. If hacker get control of 51% of nodes on the system, they can possibly ruin the integrity of the Blockchain network. It is mostly possible when someone has just launched a new cryptocurrency with only a dozen or couple of nodes, with millions of nodes afterwords will be quite difficult for hackers.

In short, bigger Blockchain network will provide more chances of security.

4. Public Perception:

People don’t see Blockchain be a part of mainstream functioning. Also, most of the people believe that this technology will not last long. The feature like the lack of governance, easy access to become a member of public Blockchain and lack of regulation further deteriorates the image of Blockchain in the eyes of people.

5. Integration with Legacy Systems:

Generally organizations has huge data residing in legacy system, also they have invested a lot over a time on existing legacy systems. There are yet much technology progress needed for integration with legacy system in Blockchain. It is not easy task.

All these factors contribute as challenges for the growth of this Technology.
