Abstract
Now a day’s electronic devices such as computers, smart phones and cameras produce enormous volumes of data each day, which require more and more storage resources. In order to fulfill this necessity, cloud storage renting sys- tems were created. Cloud storage renting disk space allows people to expand their storage capacity without having to buy and maintain additional hardware. It can help users save money on hardware and reduce the need for physical space in their home or office. It can also be used to store large amounts of data in a secure and cost-effective manner. Renting disk space also allows for easier sharing of data between multiple users, making collaboration easier and faster Cloud storage renting disk space allows people to expand their storage capac- ity without having to buy and maintain additional hardware. It can help users save money on hardware and reduce the need for physical space in their home or office. Another issue with such systems is lack of trust.To overcome these problems we use block chain technology in disk rental system. This system is designed to be a peer-to peer services where users can rent out disks to each other without the need for a third party immediately. We use the smart con- tracts which automate the rental process Here we used Proof-of-Work (PoW) consensus algorithm. This algorithm is used to verify transactions and add new blocks to the chain and also solve complex mathematical problems. If this system is implemented it Enhance security, Transparency, Lower cost, Automa- tion, and improved efficiency. Finally the system also provides a renting system to ensure that users are able to easily identify and reliable disk rental.
