Social Coin: Blockchain-mediated incentivization of citizens for sustainable collaborative processes

Citizen and end-user engagement to seek their collaboration in common good collaborative processes is hard to sustain in time. Self-motivation is not enough to guarantee sustainability of co-creation or crowdsourcing campaigns. Long-time sustainability is essential to achieve effective and positive behaviour change. This work describes our efforts to give place to an auditing and rewarding mechanism for collaborative processes enacted by the application of Blockchain. This is achieved by introducing a Social Coin. This paper describes the architecture to enable such solution and the implications of choosing different Blockchain networks for its implementation. The aim is to get ready to assess such currency in real deployments where a suite of social good campaigns encouraging fulfilment of sustainable development goals are fostered.
