su050300 / Block-Store

Decentralized application based on blockchain technology to provide storage and sharing of encrypted files as well as providing a team collaboration platform for project development.

Block-Store

- Hack36 2K20(Team: CodeBreakers)

• Creating a Dapp based on Blockchain technologies like Ethereum and IPFS(InterPlanatary File System).

Theme --> Smart Education

-->Features<--

Generic ::

• Automatic login system through metamask account address.
• User can upload file of any size(no restriction of 15 Gb like google drive).
• Cost of uploading file does not depends on the size of file rather it depends on the number of files.
• Users can search and view other users profile.

Team Collaborator/Project Manager ::

• Utilize the power of IPFS to share important files among your team members through a fully decentralized system.
• Files shared through IPFS are encrypted via Advanced Encryption Standard(AES) to provide total control as to who can access them.
• Files in a project are managed in an efficient and well defined folder structure.
• User can start a new project and send request to other users to join so as to work in a decentralized collaborative workspace.
• Any member of the project can access any file or folder of the project and can further share or delete it
• Members can also chat and post their queries regarding the project.

Global and Peer-to-Peer(Encrypted) File Sharing App ::

• Files shared between two users are easily accessible due to Blockchain technology and protected through Public and Private Keys of the users using RSA encryption.
• IPFS allows for distributed storage of data that is immune to altering and forgery. Data stored on the IPFS network cannot be altered without changing the data identifier.
• IPFS leads to improved user experience in multiple cases. Content is delivered from the closest peers that possess a copy of the content removing the single-node pressure and improving the user experience.

-->Advantages in smart education

• Files ; like video tutorials, PDFs ; shared globally can be accessed by anyone without any third party restriction.
• Friends can make groups for studying together and posting Q&A.

Advantages of Decentralized Cloud and Blockchain ::

• Transparency
• Security
• Efficiency
• Traceability

Comparison between currently used File Sharing Applications(eg. Google Drive & Dropbox) & ::

• Restrictive nature of some services as well as the more commonly understood reports of recent company data leaks.
• They are centralised systems and data shared and stored in them can easily be censored.
• We are using ipfs for file storing and sharing purpose which is based on content addressing. In case of files here , no copy of file created instead only a encrypted hash is provided to the receipent through which he can access the file.
• IPFS being content addressed it helps in lowering the bandwidth consumption and faster file access.
• User can upload their personal files that are only accessible to them (eg. certificates , important documents).
• Using of decentralized system to store files provides the user more security as our files are at great risk if they are in the hands of a single individual (they can access our personal data and can sell it).
• Global space where anyone can post any type of file ( pdf,video,image,txt) to share with other users.
• Users can also request for a particular content file in the global space by posting a request
