“…Obviously, this does not completely solve the problem since a user may lost all of storage devices. More advanced solutions suggest having a backup copy of the user's identity private data on a cloud storage managed by a third party [31]. These backup data can be encrypted by a password only the user knows, or by more advanced techniques such as the user biometric data.…”

Due to the exponential rise of the Internet in the last two decades, the digital presence has seen an enormous increase. Today, billions of people, devices and objects are digitally connected making the interactions much easier than before. To securely establish this connectivity in the digital era, proving digital identities has become crucial. Due to this, a growing number of organizations are building solutions that establish, verify and manage digital identities. Yet, a solution whereby digital identities and their associated data are efficiently managed is still far from being achieved. To fully understand the reason behind this lack, this paper provides a detailed state of the art related to identity management systems. It overviews traditional systems, analyses their strengths and limitations. This work highly focuses on the novel decentralized identity systems based on blockchain; a complete study describing their architecture, components, lifecycle and workflow is detailed. Additionally, solutions enabling decentralized identity are discussed, analysed and compared according to the ten principles of self-sovereign identity. Lastly, the challenges hindering the shift toward the fully decentralized identity paradigm are discussed.

“…Using a blockchain along with cloud storage will guarantee the security of user outsourced data. From the cloud storage perspective, blockchain is applied in different ways 1) Frequently accessed files: Shah et al [3] suggested using an adaptive algorithm through which we can identify frequently accessed files and maintain their metadata in the blockchain. This procedure will make them readily available.…”

Blockchain technology is getting more and more pertinent to solve most of the digital problems that we face today. Blockchain is notable for its prominent features like immutability, decentralization, consensus, privacy, and security. However, blockchain is still suffering from different barriers like quantum attacks, scalability problems, integration problems, incompetence to face bigdata, storage problems, and so on. The main aim of this study was to find out the scope, various problems raised, and the applicability of blockchain technology when integrated with different computing paradigms like cloud computing, edge computing, fog computing, osmotic computing, big data computing, and quantum computing. To conduct this study, we have surveyed different research articles in the combination of blockchain technology and computing paradigms. Based on this survey, we have mentioned the contemporary research works, challenges, and a list of possible research opportunities and solutions.

“…Several platforms making use of the Blockchain to verify data storage and transfers have been proposed, making use of known protocols like BitTorrent or IPFS. FileCoin [2] and others [18,7,26], use IPFS as the backbone for file storage and transfer and apply diverse logic applicable for different purposes. FileCoin makes use of a Proof-of-Replication mechanism [11] to decide that a node has spent some space for a given amount of time.…”

“…FileCoin makes use of a Proof-of-Replication mechanism [11] to decide that a node has spent some space for a given amount of time. The solutions presented in [18] and [26] propose a secure document communication protocols based on IPFS that uses the blockchain for establishing communication channel properties. In [7], the authors distinguish between hot and cold data and apply different replication mechanisms depending on their type.…”

“…This should also be ensured for the components that manage the platform, as they are also external to the Blockchain and need to maintain a state in a distributed environment. [2, 11], [7,18,26] Resource Management / Task scheduling Smart Contract maintains list of resources. Some rely on the Smart Contract to make the matchmaking, but this approach is expensive in terms of gas.…”

This article surveys the literature in search of systems and components that use Blockchain or Smart Contracts to manage computational resources, store data, and execute services using the Cloud paradigm. This paradigm has extended from warehouse-scale data centres to the edge of the network and in between, giving rise to the domains of Edge and Fog Computing. The Cloud Continuum encompasses the three fields and focuses on the management of applications composed of connected services that span from one end to the other of the computational spectrum. Several components that are commanded by Smart Contracts are identified and compared concerning their functionality. Two important research directions are the experimental evaluation of the identified platforms and the identification of standards that can accelerate the adoption of Blockchain-based Fog platforms.
