2. INTRODUCTION
Unless you were living under any caves or any dense forest with no communication with your fellow
beings, am damn sure that you would also have experienced a ton of blockchain related publicity and
witnessed the apparent benefits that it laid in different industry frameworks. I am sure that you would
have also pondered with the idealistic forecasts about the decentralized wonderland listing many
solutions to the current challenges in business transact.
There has been written and rewritten tons of articles significantly put forwarding the unbeatable
benefits and solutions, the blockchain technology can offer. Be it the
1. Blockchain in Document Verification
2. Blockchain in Supply Chain and Logistics
3. Blockchain in Defense or more.

3. The blockchain has certainly marked its footprints in different areas. However, like any other
segments, you can’t ascertain blockchain to be perfect with no shade of flaws and uncertainties.
Blockchain technology to stages boundless insufficiencies, shortcomings, and vulnerabilities. And this
article lists you with few blockchain deficiencies that you must be aware of.
It is true that blockchains have certainly experienced the ill effects of a few constraints such as
adoption and usability.
Dating back to history, blockchain technology established themselves in 2009 with the idea of
cryptographic money Bitcoin and its core operating technology. It established a framework for robust
and advanced distributed exchanges (peer-to-peer digital transactions). Nonetheless, the blockchain
technology likewise cleared a way for how organized frameworks, web administrations and
computerized networks of things are to be planned and constructed.

4. While Bitcoin presented one explicit use of blockchain innovation, a peer to peer electronic money
framework that empowers online payments, the inception of much more advanced Ethereum
blockchain on the other side, served to understand the more extensive capability of blockchain
innovation past Bitcoin.
The innovation thus soon picked up the legitimacy among a large number of individuals around the
globe, even a few governments. They now seem to be currently acknowledged, overseen, and
supported by a huge worldwide network as a stage to the decentralized applications. Thus the
different platforms of blockchain opened up a universe of unheard of decentralized conceivable
outcomes such as greater transparency in conducts, greater ease in conduct and better control of
expenditures.
However, despite the several advantages the blockchain possesses and proclaims, it illuminates some
extreme difficulties. The top five has been enlisted below:

5. 1) Scalability/Adaptability
There is no counter over the context that Bitcoin is intriguing and creative. The decentralized
framework efficiently performs the monetary activities that require an abnormal state of trust. It opens
a platform where the end user can perform the transaction without confiding in anyone. Nonetheless,
'trustless-ness' accompanies a cost. The major drawback is the number of exchanges that blockchain
technology can be handled in a predefined time interim.
Practically the majority of the notable original blockchain frameworks have these hard points of
confinement on the number of exchanges. While Bitcoin technology limits the block size, Ethereum
limits the total sum of gas in a block.
With the increased adoption of cryptographic forms of exchanges in past times, the limits of
first-generation blockchain frameworks are getting tested every now and then.
Early blockchains like Bitcoin have started witnessing the limitations on account of their protocol and
their blockchain design. As of now, the design structure of existing blockchain frameworks is primarily a
linear linked-list style blockchain. With increasing adoption and more miners pulled into the action, the
framework is likely to get tested as expanded mining pose several adaptability challenges.

6. The incapability to serve a large number of miners have already given rise to the situations such as
huge exchange rates, clogged mempools and community splits.
2) Restricted Programming
Early first-generation blockchains have already built up a base programming ecosystem.
Blockchain-smart contracts have additionally introduced computational law whereby contracts are
supported and concurred on by a blockchain which is unprejudiced and universally predominant.
Ethereum Virtual Machine was a huge advance step from the exceptionally restricted Bitcoin
programming condition.
Be that as it may, with expanding adoption, even the Ethereum Virtual Machine has hit hard points of
limitations and security traps.
3) Blockchain Security Vulnerabilities
Protocol layer security is immensely a credit of the first generation blockchain. There seem very little
instances where the Bitcoin convention or the Ethereum convention’s vulnerability got questioned up.
Their security offerings have always been considered supreme authenticating factor, around for quite a
long time.

7. However, application layer security has been lacking in some instances. Dreary application layer
security has brought about various episodes from the Equality Multi-Sig Wallet issue (which prompted
500,000 Ether being trapped) to the notorious DAO attack?—?which caused an unavoidable forking of
Ethereum into two distinctive blockchains and networks.
4) Smart contract security
Security has dependably been one of the dubious points for savvy contract stages. It began with the
DAO hack (~$60M) however has been trailed by a series of occurrences. There is at the same time
understanding in the network that blockchain platforms have the opportunity to get better in this
specific zone.
5) Convenience
The present engineering tools comes with basic functionalities and always require hacky third party
apparatuses to fill the insufficiencies and inadequacies. Furthermore, light customer implementations
focusing on mobile platforms are likewise expected to empower monstrous deployments.

8. However, the dilemma is that giving away such feature-rich instruments to third-party engineers has
not been a priority aspect yet. This in turn negatively affects the framework security like that of
blockchain smart contracts, limiting its wide adoption.
To many, blockchain technology is still in its infancy and seen in the beginning times of the
improvement. Ethereum's Light Client is pushed over for experimentations. The apparatuses required
for secure smart contract developments are still in advancement, and portable applications
collaborating with blockchains are very low in numbers.
