A blockchain is an interconnected chain of growing list of blocks. Blockchain technology is used in various domains such as crypto currency, financial services, risk management, internet of things (IoT) to public, social networks, etc. Block chain has various benefits such as decentralisation, persistency, privacy and auditability. In social networks there are various issues existing such as fake identities, no privacy, no security, exposing too much of information, spreading rumours, etc. Information that spreads across social networks can carry a lot of false claims. The development of online social networks along with the innovative media can even make rumour spreading more severe. Identifying rumour sources in social networks acting a significant task in limiting the damage caused by them through the timely quarantine of the sources. Additionally, identifying the rumour information in social network is a complex task. Therefore, this research paper proposed blockchain architecture for identifying rumours in social network using contract-based progression. This paper takes the initial step to recognise how the block chain technology can assist limit the spread of rumours.
