NETWORK APPLICATION AND MANAGEMENT
Introduction
Blockchain is an important step or advancement towards technology. It is the continuously
developing record list that could be interlinked together for the purpose of making it secured [14].
These records are also called blocks and these blocks are made secured by means of applying
cryptography algorithm. All the blocks present in the list eventually consists of a specific
cryptographic hash of any block, which is also the predecessor of the block. Furthermore, the
particular block consists of transaction of data or a time stamp. The Blockchain design is specifically
resistant to any type of modification of data [2]. The technology of Blockchain has the core capability
of recording any type of transaction between two parties. Blockchain allows the transactions in the
most effective manner. This report will be outlining a detailed description about the technology of
Blockchain. Various relevant and significant details will be given here regarding Blockchain and its
applications.
Discussion
Part 1: Blockchain
Blockchain can be defined as the technology, which eventually helps with procedure for
money transfer easily and also payment processing [4]. The supply chain is subsequently monitored
and thus data sharing is done easily. There are three aspects in Blockchain. These are architecture,
challenges and features.
i) Architecture: Blockchain consists of a specific mesh network of several important systems,
which are properly linked with each other and are not linked with the server that is centralized. All
the significant system in the mesh network define or even agree for the sharing of data and hence
remain connected with several constraints, which could be imposed on data to be shared [13]. There
are several components of the architecture of Blockchain like transactions, consensus, mining and
blocks. These are properly implemented in all the applications of Blockchain.
The first component is transaction. These are smaller blocks that help in building a system of
Blockchain. All the transactions consist of various values, specific sender addresses and relevant
receiver addresses. The transaction is utilized for shifting of value from an address to another. The
significant state of the correct Blockchain is changed [1]. All the nodes hold the copies of Blockchain.
Next, the current state is evaluated by means of process of every transaction. The transaction format
is either one or more input or output. The input is the significant reference of output for the
transactions.

NETWORK APPLICATION AND MANAGEMENT
The next component of Blockchain is block. A block is specific data structure in which the
transaction set is bundled up and is distributed with the presence of each node in the mesh. Miners
are responsible for creating this block. All the blocks comprise of the block headers for the successful
verification of block validity and metadata [11]. This metadata consists of nBits, time, nonce, version,
merkle root hash and last block header hash. The moment each and every block is amended within
the Blockchain, overwriting on them is not possible.
The next component of Blockchain is mining. Mining can be defined as the specific process
that is put in the work of real world for the purpose of creation of any valid block and is accepted in
the rest of the network [2]. All the miners thus take up the respective pending transactions and thus
verifying the accurateness of these transactions.
The fourth component of Blockchain is consensus. It is utilized for the proper checking or
verification of transaction validity. It is the collection of codified rules, which is completely self-
enforced.
ii) Features: The features of Blockchain technology refer to the characteristics of it [13]. The
several features of this technology are as follows:
a) Security: The first and the foremost feature of Blockchain technology. Due to the excess
safety or security, Blockchain is widely accepted by each and every user. Moreover, the users of this
technology are ensured regarding their money and hence they use this technology for transfer of
their money.
b) Immutability: Blockchain is eventually resistant to any kind of alteration or change and
hence the blocks are linked with cryptographic hash and since these transactions are transparent,
the users do not worry while utilizing the technology [4].
c) Reliability and Durability: The third important feature of Blockchain technology is
reliability and durability. Since all the networks of this technology are completely decentralized, the
central point of failure is not present and there is a resistant power to fight with the cyber attacks or
threats. It is also reliable and durable for technology and thus popularity is gained within limited
time.
d) Integrity: The fourth feature is the integrity. All the users could subsequently trust on the
technology since the information or data has not been changed or altered for the purpose [3]. All the
users are ensured for the integrity of their data and thus properly utilizing the technology to transfer
money.

iii) Challenges: The various challenges of Blockchain technology are as follows:
a) Costs: The first challenge is the initial cost. It is extremely higher than the rest and thus
could not be afforded easily. The software and personnel cost are high [14].
b) High Consumption of Energy: The next challenge is the high energy consumption.
c) Legacy System Integration: The final challenge is integration with the legacy system.
Moreover, it is extremely time consuming.
Part 2: Applications of Blockchain
The two applications of Blockchain technology for the domains of currency and Internet of
Things and IoT are as follows:
i) Currency: The best application of the Blockchain technology in the currency domain is
Bitcoin [5]. Bitcoin can be defined as the specific type of cryptocurrency or payment system, which is
used in the world. The first digital decentralized currency, Bitcoin is utilized for making system of
payment work without administrator help or help from centralized banks. This network is
completely P2P or peer to peer and hence all the transactions, taking place are without the
intermediaries and within users. Each and every network node verifies the transactions and this is
done with cryptography [7]. Bitcoin was invented by SatoshiNakamoto group in the year of 2009.
The currencies are eventually made with mining process. It is extremely effective and secured mode
of payment.
ii) Internet of Things: The next domain of Blockchain is Internet of Things or IoT. The
application is self driven cars [9]. The main step of the application is for the advanced technological
society. This type of service is very effective as all the individuals could simply form any particular
agreement amongst themselves to purchase the self driven car and the maintenance cost is shared
within them. These individuals would enter in Smart Contract for defining the machine ownership,
perfect utilization and maintenance requirement. These protocols of reputation are responsible for
simply enabling the services, resources and information within any group [8]. Due to the high
efficiency and effectiveness, self driven cars are easily taken by various users. This is the significant
integration of Smart contract or IoT with the technology of Blockchain.
Part 3: Socio Technical Aspects
i) Bitcoin: The various socio technical features of Bitcoin are given below:
a) Transactions: Easy transactions are possible with Bitcoin [6].

It is the sole kind of distributed ledger, which eventually helps in maintenance of an tamper proof or
permanent data transactions record. The functionalities of a Blockchain is same as the decentralized
database, which is eventually managed or controlled by the computers within a P2P or peer to peer
network. All the computers subsequently maintain the copies of the ledger for the proper
prevention of SPOF or single point of failure. Hence each and every copy is updates as well as
validated. The most significant applications of this Blockchain mainly include Bitcoin, Ethereum and
many others. The linking of the Blockchain is done in an extremely secured or cost effective manner
with any digital currency or application. The above report has properly highlighted about the core
