The importance of online social networks (OSNs) in people’s daily lives is growing, however all widely used OSNs are centralised, which brings up a number of management, security, and privacy concerns. The potential to address the aforementioned problems is provided by a architecture technology which is known as blockchain. In the below work, an Online Social Network based on block-chain is created and its decentralised operation is demonstrated. To decentralise data, a large volume of typically low-security requirements can be stored in the Interplanetary Filesystem (IPFS). Users may self-manage the OSN in a democratic manner thanks to a decentralised autonomous organisation that has been built for user autonomy
