INTRODUCTION
Data transfer in different interfaces has made the internet of things a necessity for business organizations. Data-driven society requires IOTs to extract interesting information and support faster decisions in the industrial field. Blockchain in the internet of things conduct real-time monitoring, enable automation of routine tasks and generate sensitive personal data (Kim &Lampkins, 2019). The internet of things should be controlled to maintain the privacy of a company and prevent cyber-attacks. IOTs is in electronic devices like 3D printers that have sensors for collecting data and enable the necessary computation. Also, machines for gathering information like moisture sensors prioritize the internet of things. However, it should be known that the working of the internet of things depends on the information available in a technological system.
Recent research indicates that blockchain technology works with a decentralized network and has time-stamped digital records. Digital records are contained in the blockchain with network nodes that enable its functionality (Minoli, 2019). Modern industries require the blockchain to support centralized communication models for their systems. Centralized clouds in the blockchain of the IOTs require high maintenance level. The interaction between the blockchain and the internet of things can track connected devices by use of a strong network. Blockchain and IOTs prevent man-in-middle attacks in a modern company. Smart contracts for a company are supported by the technology of blockchain and IOTs. Some of the devices which have improved in their performance because of the blockchain of IOTs include devices of Smart Homes like Smartphone and in parking solutions. Modern companies have begun smart parking measures by the help of blockchain and IOTS.
Analysis of Blockchain and the Internet of Things
Characteristics of blockchain like the ability to be immutable, auditable and transparent to allow easier interaction with the internet of things to provide security to all shared data of a company. Blockchain and IOTs provide data silos for use in computer cloud to enable data processing. Industrial systems are protected through application of blockchain and the IOTs. Blockchain and IOTs work as a framework for transaction processing and management of interacting devices. Manufacturers of computer devices need to apply blockchain and IOTs in their manufacturing process to support the lifespan of their devices (Urien, 2018). Therefore, blockchain and IOTs provides maintenance to a device and make it last longer. Generation of adequate data for computational purposes is enabled by blockchain and IOTs. Transactions in computer networks are also supported by blockchain. Business companies in need of protecting computer devices should implement blockchain and IOTs in their operations. Entrepreneurs are celebrating the technology of blockchain, which has simplified their work and increased accuracy in ways of storing data.
The blockchain of IOTs works in devices which are not restricted. In its integration, researchers have realized some drawbacks of blockchain, which include lower transaction processing power because of throughput and latency. Computer systems with blockchain suffer scalability because lots of data is processed by the new technology (Urien, 2018). Excessive use of blockchain of IOTs may undermine the privacy of company information. In all business fields, the privacy of the information on business operations is needed. Therefore, the reckless use of blockchain affects the security of some data of a company. There is need to consider computational resources when handling blockchain of IOTs because consensus algorithms are expensive and should be implemented when the manager of a company is sure on where to get an alternative of the consensus algorithms.
The Internet of Things IoT is encountering exponential development in research and industry, however it despite everything experiences protection and security vulnerabilities. Ordinary security and protection approaches will in general be inapplicable for IoT, basically because of its decentralized topology and the asset requirements of most of its gadgets. Blockchain BC that support the digital money Bitcoin have been as of late used to give security and protection in shared systems with comparative topologies to IoT. In any case, BCs are computationally costly and include high data transmission overhead and postponements, which are not appropriate for IoT gadgets. This position paper proposes another safe, private, and lightweight design for IoT, in view of BC innovation that disposes of the overhead of BC while keeping up the vast majority of its security and protection benefits. The portrayed technique is researched on a savvy home application as an agent contextual analysis for more extensive IoT applications. The proposed engineering is various leveled, and comprises of savvy homes, an overlay system and cloud stockpiles planning information exchanges with BC to give protection and security. Our plan utilizes various kinds of BCs relying upon where in the system pecking order an exchange happens and utilizes conveyed trust strategies to guarantee a decentralized topology. Subjective assessment of the engineering under basic risk models features its viability in giving security and protection to IoT applications.
In modern days, a blockchain of IOTs is applied in different scenarios to boost production processes of a company. Proper deliberation should be done before applying the blockchain of IOTs. In a scenario where a company is funding a project with little return after completion, blockchain should be avoided because it may incur high costs to the company. A standardized approach should be taken by the management of a company to determine when blockchain of IOTs should be applied (Rao & Clarke, 2019). In Smart City, the blockchain of IOTs guides generation of diverse data needed in the maintenance of resources. In a device life cycle, a blockchain of IOTs helps in maintaining system interfaces to ensure the produced products lasts to serve people for a long time. IoT devices have user data utilization feature that store data and allow productivity in computational operations of an industry.
Whenever blockchain of the internet of things is applied in an industrial field, transaction information is kept immutable. The launch of Bitcoin cryptocurrency supported full network of participating nodes. The technology of blockchain does not require an intermediary to trust when making data computations. Currently, blockchain is improved through sharding of data for effective distribution in a device. Also, allowing multiple blocks in computer devices is a way of improving the functions of the blockchain of IOTs (Zhu, Gai & Li, 2019). Parallel blockchain in a modern company is enhanced through collective signing by data miners. A combined approach is taken when designing blockchain of the internet of things. Sensor nodes support the network of blockchain. Focusing on the blockchain of the internet of things gives employees an opportunity to use lightweight nodes in computerized sensors.
To wrap data in regular transactions is the role of blockchain in the modern business world. Accuracy will be maintained in business activities after integration of blockchain of the internet of things. Blockchain has contributed to economic development because it allows industrial companies to make huge profit after minimizing errors in storage and computation of data (Zhu, Gai & Li, 2019). International companies like IBM are prioritizing blockchain of things to increase efficiency in the working of the company’s software and hardware devices (Occhiogrosso, 2018). Use of blockchain allows effective IBM services. For the blockchain network, the main components include Chaincode, ordering service and database channels. Concerning usability of the blockchain of the internet of things, this technology is easier for implementation, and all companies are allowed to plan for its installation.

Characteristics of Blockchain
Blockchain in several ways helps IoT to solve many problems. Here are the Blockchain characteristics as shown in figure 2:

a) Immutability: Building permanent records is one of the key estimations of blockchain. Every single incorporated database can be debased and normally requires trust in an outsider to keep the data honesty. When you have concurred on an exchange and recorded it, it can never be changed.
b) Decentralization: The absence of concentrated control guarantees adaptability and heartiness by utilizing assets of every partaking hub and killing many-to-one traffic streams, which thus diminishes inactivity and take care of the issue of single purpose of disappointment that exists in the incorporated model.
c) Anonymity:The anonymity gives a proficient method for concealing the character of clients and keeps their personalities private.
d) Better Security: Blockchain gives better security in light of the fact that there is no single purpose of inability to close down the whole system.
e) Increased Capacity:A huge aspect regarding blockchain innovation is that it can expand the limit of a whole system. Having a large number of PCs cooperating all in all can have more noteworthy force than a couple of incorporated servers.

Benefits of Blockchain with IoT:
Integrating Blockchain with IoT will have many advantages,
Here are the following as shown in figure 4:

a) Publicity: All members can view all the transactions as every member has its own record. The substance of the exchange is ensured by member’s private key [19], so even all members can see them, they are secured. The IoT is a unique framework where every associated gadget can share data together and simultaneously securing clients’ protection.
b) Resiliency: The Blockchain has its own duplicate record that contains all exchanges that have ever constructed in the system. Along these lines, the blockchain is better ready to withstand issues. Regardless of whether one hub was undermined, the blockchain would be kept up by each other hub. Having a duplicate of information at every node in the IoT will improve data sharing needs. Nonetheless, it presents new handling and capacity issues.
c) Speed: Processing of the transactions will be up anytime through out the day.so, the speed will be more.
d) Cost saving: Existing IoT arrangements are costly a direct result of the high framework and upkeep cost related with concentrated engineering, enormous server cultivates, and organizing hardware. The aggregate sum of correspondences that should be taken care of when there are several billions of IoT gadgets will build those expenses generously.

Blockchain and LoT:
The IoT is a fascinating creating framework that gives boundless advantages, yet there are numerous challenges with the current concentrated IoT design with the end goal that all gadgets are recognized, confirmed and associated through the concentrated servers. This model was utilized to associate a wide scope of registering gadgets for a long time and will keep for supporting little scope IoT systems, notwithstanding, it won’t be able to do giving the necessities to broaden the IoT framework late.
Table shows an examination among blockchain and IoT. There are numerous focal points of the two advances, which can be joined, and get an improved result. The IoT has boundless advantages and receiving a decentralized methodology for the IoT would settle numerous issues particularly security. Receiving an institutionalized shared correspondence model to processthe many billions of exchanges between gadgets will fundamentally diminish the expenses related with introducing and keeping up huge concentrated server farms and will appropriate calculation and capacity needs over the billions of gadgets that structure IoT systems. This will forestall disappointment in any single hub in a system from carrying the whole system to an ending breakdown.

RESEARCH METHODOLOGY
Research was conducted to evaluate the need for blockchain and internet of things. Research questions included: How does blockchain adapt to the internet of things? How should blockchain be integrated with the internet of things? Explain the feasibility of blockchain of IOTs in improving operations in an industrial field? The research questions guided effective qualitative research and allowed the researcher to have a focus on the information needed for the journal article. I focused on some comments from IBM human resource managers on the importance realized from the Blockchain of the IOTs. There were two hypotheses targeted in the research:
H1:Blockchain of IOTs target connecting things and data by the help of strong internet.
H2: Blockchain, when integrated with the internet of things, allows thing-to-thing communication.

RESULTS
The research done reveals that blockchain provides solutions to IOTs. The technology in blockchain supports data processing, allow data collection, storage and sharing. The adoption of blockchain to the internet of things is due to its nature of decentralizing database. Use of blockchain technology supports faster, safer and cheaper ways of processing data. Blockchain of IOTs in financial matters enables real-time tracking of credit records. Also, technology is a value drive for it supports the automated settlement of financial data. The review of the way IBM applies blockchain and IOTs reveals that the technology is needed in areas like asset rehypothecation, making global payments and in many other fields. Therefore, modern companies should avoid despising the role of IoT in empowering blockchain. Principles in a blockchain that allow its adoption with the internet of things include scalability, consistency and decentralization (Rao & Clarke, 2019). In computerized devices, blockchain software is set to indicate the database layer, which allows computation and processing of data. In supply chain management, stocks exchange, identity management and credits transfer; blockchain of the internet of things is needed.
Blockchain is real, and its concepts are applied in trade stores, music licensing and electric vehicle charging. Currently, over 15 billion IoT apparatus is operational and use the internet. The sensor modules of the internet of things allow accessibility of network in IOTs devices. In modern industries, technologists have conformed on the feasibility of IoT devices (Rao & Clarke, 2019). It is interesting to know that most of the company duties have become easier to work on because of the integration of blockchain. Blockchain, when connected with IoT, reduces errors in the computation of data. The feasibility of blockchain allows its use in communicating results of large transactional data after a company participates in global trade. The distributed ledger in a blockchain boosts its performance, especially when connected with the internet of things. For a blockchain to operate, there must be a transaction, a chain, block and network.
Objects become part of the internet when blockchain is connected with the internet of things. Making a computerized object to access the network boosts its performance. Physical word is connected to digital technology when organizations implement blockchain and take the right measures to adopt the internet of things. There is no doubt that the world will get industrialized at a faster pace because of the integration of blockchain and internet of things. Internet ensures devices function faster and access large data within a short period. Although human beings control technology and any update involving blockchain and internet of things, the capabilities of connecting internet to devices seems to function more intelligently than manual work conducted by human beings(Kim &Lampkins, 2019). For instance, research involving review of online journals seems more appealing to scholars. Also, many people are working nowadays through online platforms because blockchain and IoT have provided a breakthrough to people who appreciate technology in their daily activities. The growing trend of using the internet of things has an impact on the global economy. IoT supports economic development, especially when applied together with blockchain.
Internet of things allows people to interact online to discuss business projects or socialize as friends. It is a technology favoring young people and adults. There is a need for every organization to begin implementing the blockchain and IoT. However, the implementation of Blockchain technology should consider the security standards of an organization, constraints of devices to connect to the internet and the means of communication. The list of records in an organization can be effectively stored and updated with the help of blockchain of the internet of things. Data stored on blocks of the blockchain is not easily interfered by the members of the public. Decentralized identity management allows blockchain to favor all company managers(Minoli, 2019). The addition of a miner to the blockchain helps handle resource-intensive cryptographic. The blockchain of the internet of things is advantageous in securing business records. A blockchain serves to counter regular cases of cyber threats in an organization. In a company storing data for many customers, the security of information is needed. Therefore, integration of blockchain of IoT will secure the data processed and contribute to a better reputation of the company. A business company grows faster because of the customers’ interest. Whenever the security of data is assured to customers, sales of the company increase and result in better corporate profits. Blockchain of IoT has a contribution to the profits of an organization since it improves its reputation and motivates customer retention.

SUMMARY
In conclusion, blockchain in the internet of things allows computer systems to connect to a network and process large data within a short period. Blockchain is a technology that is revolutionizing the way business is conducted in modern days. It involves a list of records linked to cryptography. Blockchain allows the history of a device to have a digital asset. Operations of a company improve because of blockchain in the internet of things. To implement blockchain in IoT is expensive, but a company should not ignore this technology for it boosts many operations that create more profit.
The IoT innovation has stretched out that come to each home known to mankind. It can interface ordinary articles to the Internet. Through modest sensors, a ton of data can be gathered from the general condition that outcomes in improving our life. In any case, current IoT design that dependent on server/customer model has numerous issues that should be tended to particularly adaptability and security. One of the answers for address IoT issues is blockchain.
