Distributed Computing in Blockchain Technology

Proposed Model for Secured Data Storage in Decentralized Cloud by Blockchain Ethereum

“…Individual resources are split into shards and allocated (with replication to ensure availability) to different nodes in such systems. In some related research [1][2][3][4], blockchain is shown to be a secure and distributed ledger that can assist in overcoming many of the difficulties associated with centralization. However, their main goal was to provide insights into the use of security services for current applications, highlight the innovative techniques currently used to offer numerous benefits, describe their challenges, and discuss how blockchain technology can resolve them.…”

“…Cloud computing is costeffective, and all IT areas are migrating to it. However, the considerable development and demand for cloud computing have resulted in significant concerns about its security and privacy, defined by the rules, regulations, and technologies required to secure information, applications, and the cloud computing infrastructure [3]. Data protection, transparency, and availability are the three pillars of traditional data security.…”

“…Although blockchain uses a distributed database, data corruption is more complicated. According to the rules, the data is encrypted and processed through blockchain software machines [3].…”

“…Users have full control of their accounts using EOA, and contract accounts are controlled by their unique smart contract code. Ethereum brings the blockchain idea to the next level by allowing users to establish financial contracts, known as smart contracts, within the system, in a matter of minutes [3].…”

“…In contrast, the provider should not keep a customer's data in primary or backup storage if the client believes it has already been deleted. Furthermore, if data is held in a specific country, it may be governed by that country's privacy laws rather than the rules applicable in the client's geographic region [3].…”
