Existing systems work on the principal of keeping persistent TCP connection between users and server to facilitate communication between end users. Whatsapp recently claimed to have reached a capacity of one million established TCP connection on a single machine. This method is expensive and not feasible as to ensure continued growth, these systems need to be added with extra machines to handle such connections. This will increase in cost and usage of electrcity which isn’t ecofriendly. If we include redundent systems for backup’s the number just increases. Also a big concern in such centralized system architecture is security, as all the data is stored in central servers they are prone to attacks. All correspondence goes through the server of the company owning the messaging app, and the company can dictate its rules: block messages on a certain subject or prohibit the transfer of certain files. The company may also be subject to government pressures and may be asked to disclose users’ correspondence or to impose certain restrictions upon their request.
The proposed solution is free from any form of centralization and only uses a psuedo server for peer-discovery.
