Other top winners included Egypt’s Carboni Renewable Energy Certificate Platform, which took second place overall, and Mexico’s Effisend X Africa, an AI-powered payment routing system, in third. Organizers noted that the 2025 submissions shifted toward pragmatic infrastructure, including systems for cross-network payments and secure medical record management.
Coinciding with the awards, The Hashgraph Association announced the formation of a new investment committee. The body is designed to provide multi-million-dollar commitments to strategic partnerships, offering capital and mentorship to developers in emerging markets.
“Any strong, innovative and responsible technical ecosystem begins with education,” said Paolo Tasca, executive chairman at Exponential Science. “We have seen that approach materialize at scale, with participants advancing from learning to the development of meaningful infrastructure.”
The hackathon was co-funded by The Hashgraph Association and Exponential Science in partnership with Orange Digital Center and operated by Dar Blockchain. Supporting partners included Sygnum Bank and the Nairobi Securities Exchange. The Hashgraph Association confirmed the event will return in 2026, with details on location and tracks to be released at a later date.
