A Systematic Literature Review: Blockchain Based Solutions for IoT’s

Abstract

In the modern era, Internet of things brought revolution in the everyday life activities by automation in everyday functions, modifying the approach of people to collaborate with one another or with the devices. Actually, the main feature of IoTs is direct device to device interrelationship. Their benefits range from little domestic devices to heavy industrial systems. Despite of numerous advantages of IoTs, their execution contains different issues mostly due to the severe substance of the functions by implement and because of their narrow computing abilities. Blockchain is the forthcoming annoying technology field that has achieved the attention of IoT sectors to tackle the problems by becoming encountered by themselves. In the article, the relevant issues in IoT field are pointed by us and then examined by the method how these issues can be resolved with the help of Blockchain features. Furthermore, we have also identified issues that appear while allocation of blockchain (BC) in Internet of things (IoTs).

Blockchain and the Internet of Things: Challenges in Monitoring System For Covid-19

“…Nonetheless, IoT gadgets are restricted in resources. As the IoT network comprises of countless necessities so this blockchain network inadequately scaled because of the computational power needed for POW [19,20].…”

“…The blockchain offers a distributed computational facility architecture that eliminates the vast majority of the restrictions related with the integrated computing network. Blockchain is an variety of computing hubs that are linked in a distributed peer-topeer (P2P) method and commonly check transactions implemented inside the network [20]. In the Blockchain, every block cryptographically closes a bunch of transaction and is connected with prior block to construct a hash based (cryptographically ) group of blocks.…”

“…In the Blockchain, every block cryptographically closes a bunch of transaction and is connected with prior block to construct a hash based (cryptographically ) group of blocks. Blockchain is a decentralized database to keep the history of transaction along with timestamps [3,20]. Blockchain begin through a primary block known as a genius block.…”
