Article 1
CITATION Block chain technology: applications in health care.
SUMMARY The block chain technology is gaining immense attention in recent years
with the hiked interest in different fields, involving the healthcare industry.
This technology offers one secure as well as distributed database, which can
managed and operated without any administrator or the central authority.
Block chain utilizes a peer-to-peer and distributed network for making a
growing continuous list of all the ordered records, which identified as the
blocks in order to form one digital ledger. In every transaction that are
presented in the signed block in a cryptographic manner, is identified and
validated by the network itself automatically (Angraal, Krumholz & Schulz,
2017). Apart from that, the block chain technology have also gathered
immense interest as one efficient platform for improving the transparency as
well as authenticity of the sensitive and confidential healthcare data by
many use cases, which includes maintenance of the permission in the
electronic health records (EHR) and streamlining claims processing. In the
particular article the author majorly focused on the basics of the block chain
technology. The impact along with the recent and future applications of the
technology in a healthcare perspective has also illustrated.
CRITIQUE The critical analysis and the diagrammatic explanation provided by the
author has made the article an authentic one.

CITATION Block chain technology: Beyond bitcoin.
SUMMARY A block chain is identified as the distributed database of several records and digital
events which has shared as well as executed between all the participating parties.
Every transaction that occur in public ledger gets verified through the consensus of
all participants in system. In addition to that, the article explains that, block chain
contains verifiable record of all the transactions. Bitcoin, is identified as the peer-
to-peer decentralized digital currency and the most common example which uses
the block chain technology (Crosby et al., 2016). The important hypothesis is,
block chain establishes one system for designing the distributed consensus in
digital world. Block chain is beneficial for developing a scalable and democratic
digital economy that differs from the centralized one. In this article, the author has
explained block chain technology and its use in financial and non-financial sectors.
CRITIQUE The author has described the business opportunities as well as the challenges of
technology and the authentic resources used here provide a strong support to the
article.
Article 3
CITATION Block chain: A panacea for healthcare cloud-based data security and
privacy.
SUMMARY One emerging trend noticed in the healthcare is the shift of service as well
as data to the cloud approach, mainly due to the convenience and the
savings. However, there exist limitations in using this specific cryptographic
control models for addressing the privacy and security concerns in the

cloud-based environment. The block chain technology can build a
distributed online database comprising with the data structures, which is
also identified as blocks, are linked with one another. Each block is
associated with timestamp of the production along with the hash associated
to the previous block and a transaction data, which is responsible for a
secure environment for the healthcare data.
CRITIQUE As opined by Esposito et al. (2018), the cloud based approach along with
the block chain facilities can efficiently manage and secure the health care
data.
Article 4
CITATION Managing IoT devices using block chain platform.
SUMMARY The block chain technology has unfolded as a revolutionary technology in
the current technological age. Though this technology was started off as the
core technology of the Bitcoin, currently its advantages has spread to
several fields including the Internet of Things (IoT) and security. As the
hardware and software improve, beginning of IoT is well-noticed. In order
to perform several operations, the IoT devices need to synchronize and
communicate with each other. However, in several cases where more than
thousands of IoT devices need to connect with each other, it might lead to
several potential challenges (Huh, Cho & Kim, 2017). The author has
described the usefulness of block chain in building the complex IoT system.
Block chain can be used to configure and control the IoT devices. The
