Since the concept was first proposed in 2008, there has been a surge in Blockchain technologies’ interest. The core qualities of Blockchain that include encryption, anonymity, and high availability without a third-party entity in charge of transactions, are driving interest in the technology, which opens new research opportunities, especially in terms of technological benefits and issues. We performed a comprehensive mapping analysis to gather all related research in Blockchain technologies for this study. We aim to comprehend existing research issues, problems, and potential directions in Blockchain technology from a technical perspective.
From science databases, we’ve pulled 41 primary documents. The findings reveal that over 80% of the articles are based on the Bitcoin scheme, with just 20% dealing with the other Blockchain implementations, including such payment systems and licenses. The bulk of the study focuses on uncovering and enhancing Blockchain’s privacy and protection flaws, but many developers ignore clear evidence of their efficacy. Many other issues related to Blockchain scalabilities, such as throughput and latency, have gone unexplored. Researchers will receive guidance for future research directions based on the findings of this report.
Currency exchanges between individuals or businesses are often decentralized and regulated by a third party. To complete a digital deposit or currency swap, you’ll need a bank or card issuer to serve as a middleman. A charge often results in a deposit from a bank or even a credit card provider. The same method is being used in various other fields, including sports, songs, electronics, and so on. Instead of the two major political parties participating in the transaction, the transaction structure is usually consolidated. All data and knowledge are handled and maintained by a third-party entity. To address this problem, blockchain type of technology. Blockchain technology aims to establish a transparent system in which a third party does not control transactions or data.

Swan Identifies Five Technological Obstacles And Barriers To The Potential Use Of Blockchain Technology:
The Bitcoin network’s maximum possible throughput for problems is currently set at 7tps VISA (2,000 tps), and Twitter is two other payments transmission networks (5,000tps). The throughput of both the Blockchain network must be increased when the number of trading of Blockchain approaches similar amounts.
It currently takes a long time to complete a Bitcoin limit access with real support. Since the cost of double expenditure attacks must be outweighed, more time must be expended on a block to achieve security reliability. The act of successfully investing money multiple times is known as double-spending. Bitcoin prevents double-spending by checking each transaction applied to the Blockchain to guarantee that the transaction’s inputs have not been used before. As a result, latency is a significant problem in Blockchain. Although keeping stability, creating a block, and verifying the transaction can take just a few seconds. A trade, for example, in VISA, requires just a few seconds to complete, which is a significant benefit over Blockchain.
Scale And Bandwidth:
Currently, a Blockchain throughout the Bitcoin network is over 50,000Mbps (February 2016). As throughput reaches VISA thresholds, Blockchain could expand by 214 billion dollars per year. The Bitcoin community believes that each block is 1Meters in length and that new blocks are created every ten minutes. As a result, the number of data that may be processed is limited (on average, 500 transactions per block). If the Blockchain is to monitor further transfers, the problems of scale and bandwidth must be addressed.
Safety Is Important:
A 51 percent assault on the existing Blockchain system is possible. A 51 percent intrusion will give a single party complete control over the bulk of the network’s mining transaction volume, enabling them to exploit Blockchain. Tools threw away Bitcoin mining consume a lot of electricity ($15 million per day). The Proof-of-Work initiative in Bitcoin is to blame for the waste. In the world of industry, there are several substitutes, such as proof-of-stake. The miner’s work determines the likelihood of extracting a block in a Proof-of-Work system. In Proof-of-Stake, on the other hand, the resource being compared is the sum of Bitcoin a miner owns. Someone who owns 1% of Bitcoin, for example, will mine 1% of the “Proof-of-Stake blocks” . To get more effective mining in Cryptocurrency, the problem of expending time must be resolved.
The Blockchain API is challenging to use when evolving utilities. A need to provide a development company Blockchain API. This may be compared to Apis. Many chains, rough forks, and versioning: The probability of a 51 percent attack is more significant in a short chain with a small node density. When chains are broken for operational or versioning reasons, another problem arises.
