Abstract of blockchain

Blockchain is a decentralized transaction and data management technology developed first for Bitcoin cryptocurrency. The interest in Blockchain technology has been increasing since the idea was coined in The reason for the interest in Blockchain is its central attributes that provide security, anonymity and data integrity without any third party organization in control of the transactions, and therefore it creates interesting research areas, especially from the perspective of technical challenges and limitations. In this research, we have conducted a systematic mapping study with the goal of collecting all relevant research on Blockchain technology. Our objective is to understand the current research topics, challenges and future directions regarding Blockchain technology from the technical perspective.

What is blockchain?

Skip to content. Change Language. Related Articles. Table of Contents. Improve Article. Save Article. Like Article. The blockchain is a distributed database of records of all transactions or digital event that have been executed and shared among participating parties.

Each transaction verified by the majority of participants of the system. It contains every single record of each transaction. BitCoin is the most popular cryptocurrency an example of the blockchain. Blockchain Technology Records Transaction in Digital Ledger which is distributed over the Network thus making it incorruptible. Anything of value like Land Assets, Cars, etc.

How Blockchain Technology works? One of the famous use of Blockchain is Bitcoin. The bitcoin is a cryptocurrency and is used to exchange digital assets online. Bitcoin uses cryptographic proof instead of third-party trust for two parties to execute transactions over the internet.

Each transaction protects through digital signature. The data is distributed over Millions of Computers around the world which are connected with the Blockchain. This system allows Notarization of Data as it is present on every Node and is publicly verifiable.

A network of nodes: A node is a computer connected to the Blockchain Network. Node gets connected with Blockchain using the client. Client helps in validating and propagates transaction on to the Blockchain. When a computer connects to the Blockchain, a copy of the Blockchain data gets downloaded into the system and the node comes in sync with the latest block of data on Blockchain.

The Node connected to the Blockchain which helps in the execution of a Transaction in return for an incentive is called Miners. Previous Introduction to Blockchain technology Set 2.

Introduction to Blockchain Specialization

Blockchain is an emerging technology platform for developing decentralized applications and data storage, over and beyond its role as the technology underlying the cryptocurrencies. The basic tenet of this platform is that it allows one to create a distributed and replicated ledger of events, transactions, and data generated through various IT processes with strong cryptographic guarantees of tamper resistance, immutability, and verifiability. Public blockchain platforms allow us to guarantee these properties with overwhelming probabilities even when untrusted users are participants of distributed applications with ability to transact on the platform. Even though, blockchain technology has become popularly known because of its use in the implementation of Cryptocurrencies such as BitCoin, Ethereum, etc. Many researchers are working on many such use cases such as decentralized public key infrastructure, self-sovereign identity management, registry maintenance, health record management, decentralized authentication, decentralized DNS, etc. Considering the need to disseminate the emerging concepts for students, we decided to prepare a new course on blockchain technology platforms and applications. Course abstract Blockchain is an emerging technology platform for developing decentralized applications and data storage, over and beyond its role as the technology underlying the cryptocurrencies.

Introduction to blockchain technology

Trials volume 18 , Article number: Cite this article. Metrics details. Reproducibility, data sharing, personal data privacy concerns and patient enrolment in clinical trials are huge medical challenges for contemporary clinical research. A new technology, Blockchain, may be a key to addressing these challenges and should draw the attention of the whole clinical research community. Blockchain brings the Internet to its definitive decentralisation goal. Therefore, users have a high degree of control over and autonomy and trust of the data and its integrity. Blockchain allows for reaching a substantial level of historicity and inviolability of data for the whole document flow in a clinical trial. Hence, it ensures traceability, prevents a posteriori reconstruction and allows for securely automating the clinical trial through what are called Smart Contracts.

Introduction to Blockchain and IoT

This paper aims to strive to close the current research gap pertaining to potential implications of the blockchain for supply chain management SCM by presenting a framework built on four established economic theories, namely, principal agent theory PAT , transaction cost analysis TCA , resource-based view RBV and network theory NT. These theories can be used to derive research questions that are theory-based as well as relevant for the industry. This paper is intended to initiate and stimulate an academic discussion on the potential impact of the blockchain and introduces a framework for middle-range theorizing together with several research questions. This paper builds on previous theories that are frequently used in SCM research and shows how they can be adapted to blockchain-related questions.

Blockchain technology for improving clinical research quality

Health services must balance patient care with information privacy, access, and completeness. The massive scale of the healthcare industry also amplifies the importance of cost control. The promise of blockchain technology in health services, combined with application layers built atop it, is to be a mechanism that provides utmost privacy while ensuring that appropriate users can easily add to and access a permanent record of information. Blockchains, also called distributed ledgers, enable a combination of cost reduction and increased accessibility to information by connecting stakeholders directly without requirements for third-party brokers, potentially giving better results at lower costs. New ventures are looking to apply blockchain technology to solve real-world problems, including efforts to track public health, centralize research data, monitor and fulfill prescriptions, lower administrative overheads, and organize patient data from an increasing number of inputs. Here, concrete examples of the application of blockchain technology in the health sector are described, touching on near-term promise and challenges.

Cryptographic Primitives in Blockchain Technology: A mathematical introduction

This emerging technology is generating a huge amount of interest amongst the technology community in Silicon Valley and elsewhere. It is widely predicted to transform huge swathes of industry over the next five to ten years and beyond. A vast number of potential applications have been identified, some of which are already starting to be exploited. Blockchain can best be described as a digital platform or database for securely storing information and recording transactions. However, there are some key points to be aware of:. Whether a blockchain is private or public will, as the name suggests, determine the user group that has access to the information on that blockchain.
