How It Works
All documents are stored in so called permanent web powered by IPFS protocol.
IPFS protocol took advantage of blockchain protocol and network infrastructure in order to store unalterable data, remove duplicated files across the network, and obtain address information for accessing storage nodes to search for files in the network.
IPFS has no single point of failure, andnodes do not need to trust each other not to tamper with data in transit IPFS provides deduplication, high performance, and clustered persistence. IPFS and the Blockchain are a perfect match!
Large amounts of data can be stored with IPFS and linked into a blockchain transaction. This timestamps and secures content, without having to put the data on the chain itself
