While the Smart Contracts are open source, the front end is closed source. So it is impossible to understand what is happening on the server hosting the front end Peepeth.com. Image files are not only stored in IPFS but also mirrored at Amazon AWS to provide a better user experience. Basically, the client does not communicate directly with IPFS, but the server behind the front end communicates with the two back end technologies IPFS and Ethereum Blockchain, as shown in Figure \ref{fig:peepeth-architecture}.
