Better data collection means the demonstrable efficacy of development programs, shareable with donors, and insights into how to improve. All of which means greater access to funding over the long-term and more effective impact on local communities Based on blockchain technology, we have developed the architecture behind a system that takes advantage of the widespread use of mobile phones in the developing world to connect development program providers with their beneficiaries to collect data on the impact of their programs. This is done through a tokenized, permissioned blockchain that measures the outcomes of programs on an immutable ledger. The data will benefit the organisations seeking to maximize their impact, and the transparency the blockchain provides will give donors confidence that their funding efforts are having the impact they desire.
