Abstract
AbstractWith the development of storage technology and Internet technology, cloud storage continues to make its impact. Scalability, reliability, and lowered costs have made cloud storage widely used with success in businesses and individuals. The advent of the blockchain has brought some changes. As the incentive layer for IPFS, Filecoin allows storage resources to become tradable, greatly extending storage capacity. However, the process of testing the integrity of data still needs constant improvement. In this chapter, we propose a new data audit proof, in which nodes continuously upload hashed data that has been added to random numbers, and the smart contract will compare the result to verify the integrity of the data. Meanwhile, data owner could calculate and then challenge to verify the data integrity. There are audit miners responsible for regulating the behavior of miners and the protection of users’ data, and audit miners in a state of semi-participation. It is demonstrated later in the chapter that this proof is accurate enough and resistant to attacks.
