The Blockchain is an ingenious and remarkable invention. This technology created the backbone of a new type of internet. It was originally designed for the digital currency, Bitcoin, in which you can send digital money to anyone, even a stranger. Originally, it transmits bitcoin. It is considered a revolutionary technology. Blockchain helps in creating the record whose authenticity can be verified by the entire community. To make centralized and distributed systems it stores the data over a network of computers, which anyone can use this system, no central organization or person owns a system. It contains a number of blocks that contain data. The database of Blockchain is not stored at a single location, it is an open-source database which can be accessed by anyone and it is easily verifiable. No one owns the blockchain technology. As the blockchain’s nature is distributed, there must be a simple way by which all the nodes reach an agreement; Consensus agreement is a way by which all the participants agree on the contents of the blockchain. Here we will tell you about the basic principles and characteristics of the Consensus Algorithms so that you can decide which of the algorithm the best one to work with is. In this paper, we will research on the number of technical aspects of Blockchain technology, the pace in which this technology is booming and most importantly its implementation on the Bitcoin cryptocurrency which has totally revolutionized the financial infrastructure of the World. Along with this, we will also consider a number of security concerns, challenges and other technical vulnerabilities associated with the Bitcoin technology. The decentralized mechanism, distributed mechanism, scripted mechanism and the mechanism of the password related to Blockchain has opened a new view on the rapidly developing internet technology. There is no need for participants or any third party who are needed to be known to each other. The responsibility is included in the recording, transmission and the activities regarding transferring the storage by distributed technology. That is how the assurance is guaranteed by keeping these aloof from tampering and forged. With the assistance of asymmetric cryptographic algorithm, each and every participant can reach towards consensus on the information of the blockchain. The blockchain technology has the potential to play a key role in the case for information security technology. Hence, in this paper we will also cover the impact of the blockchain will ensure the expansion in the sphere of information security

An Analysis of Blockchain Technology A Security and Privacy Perspective, 2022

A distributed ledger technology that took over the world in recent days is Blockchain technology. It is simply a list that grows continuously holding the records of the transactions and data records securely in the form of blocks. It is also referred to as technology similar to linked lists where blocks are interlinked to each other [20]. A header block and the body block are the two main components of each block in the blockchain [41]. Usually, the header block holds the information about the management information of the block and the chain. The nodes of the blockchain communicate directly with each other through a peer-to-peer network. Every node consists of its digital signature [30] to validate the transactions. Blockchain technology brings the features like transparency, decentralisation, anonymity, and audibility. These features have gained the interest of both researchers and industries. Nowadays blockchains are extensively used in the fields of finance, medicine, agriculture, transportation, and Internet of Things [25] [38]. But we need to consider the security and privacy-related challenges in order to effectively use this new technology. Today most of the researches are going on the security and the privacy issues of the blockchain. The researches mainly focus on two concepts, analyzing the attacks which have been suffered by the blockchain recently and proposing some of the countermeasures against the type of attack. However, there are very little researches that provide an in-depth analysis of these issues The focus of this chapter is on examining current trends in blockchain security and privacy problems. The chapter is laid out in a fairly orderly fashion. The first portion of the chapter covers the fundamentals of blockchain technology, including the various types of blockchains, blockchain architecture, and consensus methods. The most recent and likely cyberattacks and issues on blockchains are described in the next section. The solutions section lists some of the legitimate current countermeasures to the attacks presented. Finally, the article highlights the unresolved concerns that will need to be handled effectively in the future.
