The survivability of a blockchain network is influenced by the diversity of its nodes. Trustworthy device-level attestations permits nodes in a blockchain network to provide truthful evidence regarding their current configuration, operational state, keying material and other system attributes. In the current work we review the recent developments towards a standard attestation architecture and evidence conveyance protocols. We explore the applicability and benefits of a standard attestation architecture to blockchain networks. Finally, we discuss a number of open challenges related to node attestations that has arisen due to changing model of blockchain network deployments, such as the use virtualization and containerization technologies for nodes in cloud infrastructures. KeywordsAttestation, Ipfs, Decentralized Storage,etc. INTRODUCTION We believe there is a crucial role for trusted computing technologies, and more specially attestations technologies, within the nascent area of blockchain networks. As blockchain networks play an increasing role in the future digital economy such as becoming the underlying infrastructure for future crypto-currencies and virtual assets exchange networks the security, resiliency and survivability of blockchain systems becomes crucial to their business value-proposition. Since the dawn of the computer age and the development of networked computer systems and the Internet, there has been the need for operators of computing equipment to obtain correct and truthful insights into the state of computing devices as part of managing the security of these devices. Given the proliferation of malware and viruses in the past decade, there has been a need for networked devices to have the capability to report its configuration, internal state and other parameters in a truthful and unforgeable manner. The technical term used to describe this process is attestations. The goal of the current work is threefold. The first is to review the current development towards a standard attestation architecture in the computer and network industry. Secondly, to explore the applicability and benefits of the attestations architecture to nodes in a blockchain network. Thirdly, we discuss some of the current challenges in attestations that has arisen due to changing model of blockchain networks, such as the use virtualization technologies for nodes in cloud infrastructures. Literature Survey Decentralized attestation :-Author is F. Harer and H.-G.-Fill Decentralized attestation methods for blockchains are currently being discussed and standardized for use cases such as certification, identity and existence proofs. In a blockchain based attestation, a claim made about the existence of information can be cryptographically verified publicly and transparently. Blockchain System-A blockchain is a data structure of linked blocks, where each block is linked to one predecessor by the value of a hash function for providing integrity across the chain. Attestation Concept- In the context of conceptual modeling, these ideas can be applied for the remote attestation of model artifacts, bound to the identity of a user. Here, a model-based attestation can be conducted by (A.) the creation of a claim about the existence of a model, bound to an identity (B.) the validation of the claim by any other identity at a later point in time. In such a system, an attestation can be conducted by the issuance of a claim through a user, referred to as Claim Issuer, who records the claim for it to become part of the trusted global state, and by validating the claim through a user, referred to as Claim Validator.
