Although the Social Cloud project as suggested in the paper has not flourished, as of January 2016, several projects that are aligned with or can be regarded as proof of concepts of the Social Cloud vision presented in the 2009 have matured. Those interested in the ideals presented in the Social Cloud paper are encouraged to look further into the projects presented bellow.
The FreedomBox personal server project
"FreedomBox is a personal server that protects your privacy. It hosts on demand applications such as file sharing, shared calendaring, instant messaging, secure voice conference calling, blog and wiki. FreedomBox is a free software stack, a subset of the Debian universal operating system, that can be installed in many flavors of inexpensive and power-efficient hardware. The simplicity of setting up and operating a FreedomBox is similar to that of a smart phone."
Blockchain distributed database and smart contract projects
These projects are being cited here as mere examples of blockchain distributed database. The author is not encouraging monetary investments in cryptocurrencies.
