Adoption Of Pets In Distributed Network Using Blockchain Technology by Manoj Athreya A, Ashwin A. Kumar, Nagarajath S. M, H.L. Gururaj, Ravi Kumar V Abstract: As the whole world is moving towards digital payments, ethers and the transaction methods with quick payment features are stored in a blockchain in a distributed network. To adopt pet animals, this technology provides security and flexibility to users. The distributed network is a network system through which data, software and computer programming are spread across on more than one node(computers) and these nodes are dependent on each other. It is nothing but a peer-to-peer network which eliminates a single point of failure. The blockchain is a growing list of records called blocks, that are linked using cryptography. It is a decentralised, distributed and an immutable ledger to store digital transactions. Its databases are managed using a peer-to-peer network where all the nodes in a network are equal and are the major concern in the types of network architecture. The consensus protocol is used for transacting and communicating between the nodes. In this paper, a unique way of adopting pets is proposed where the transaction details are stored in a blockchain whereby using hash value returns further details of the transaction. It provides users more convenient access in adopting pets and provides a better approach to the existing centralised system. Keywords: Blockchain; Decentralized; Distributed; peerto-peer network; Smart contracts. DOI: 10.1504/IJBC.2019.10024984
An overview of food supply chain virtualization and granular traceability using blockchain technology by Jitendra Yadav, Madhvendra Misra, Sam Goundar Abstract: The integration of sensors and internet to the supply chain has created a new window in the supply chain management called as virtual supply chain which bears the features such as real-time tracking and monitoring of goods flow in the physical supply chain. The food supply chain is one of the delicate supply chains due to perishability, which can be due to various physical and biological factors, also the stringent safety and sustainability requirements of the product. The use of sensors and IT technology enables real-time data collection of the changes that take place in the food supply chain. The paper presents the integration of blockchain to the current virtual supply chain thus eliminating or changing the roles of intermediaries in the virtual supply chain and facilitating transparency, integrity, and authenticity of the data in the food supply chain. Keywords: Blockchain; food supply chain; virtual supply chain; sensor; sustainability. DOI: 10.1504/IJBC.2019.10026124
Towards Characterizing Architecture and Performance in Blockchain: A Survey by Vinicius F. Rodrigues, Fabrício Reis Furtado, Josué Valtair Silva e Silva, Márcio Junior Cappelari, Cláudio Henrique Murussi Castilhos, Cristiano André Costa, Rodrigo Da Rosa Righi Abstract: Since the launch of Bitcoin, the interest in Blockchain technology has grown over the years and has attracted many researchers. There are several proposals to improve the performance of the Blockchain, however these proposals bring a series of changes, which are difficult to implement and most of them are not compatible with existing applications. The current limitations prevent Blockchain from being used on a large scale for other types of applications or even replace the currently known electronic payment methods, making studies necessary to address these gaps and evolve the technology. This paper presents a literature review of Blockchain technology with focus in architecture, security, and performance, providing an understanding about the main features and exploring the current open gaps, in light of the main tools used in the systematic literature review methodology. A taxonomy is also proposed to support design solution and helping to classify Blockchain systems. Keywords: Blockchain; Architecture; Performance; Security. DOI: 10.1504/IJBC.2019.10027994
