Query: Content Addressed P2P File System for the Web with Blockchain-Based
  Meta-Data Integrity   With the exponentially scaled World Wide Web, the standard HTTP protocol has
started showing its limitations. With the increased amount of data duplication
& accidental deletion of files on the Internet, the P2P file system called IPFS
completely changes the way files are stored. IPFS is a file storage protocol
allowing files to be stored on decentralized systems. In the HTTP client-server
protocol, files are downloaded from a single source. With files stored on a
decentralized network, IPFS allows packet retrieval from multiple sources,
simultaneously saving considerable bandwidth. IPFS uses a content-addressed
block storage model with content-addressed hyperlinks. Large amounts of data is
addressable with IPFS with the immutable and permanent IPFS links with
meta-data stored as Blockchain transactions. This timestamps and secures the
data, instead of having to put it on the chain itself. Our paper proposes a
model that uses the decentralized file storage system of IPFS, and the
integrity preservation properties of the Blockchain, to store and distribute
data on the Web.
