A donation disappears the moment it is made. The donor gets a receipt, and then nothing — no view of where the money went, what it paid for, or whether it changed anything.

That is the second problem statement released for FirstBlock-athon, presented by Hundstallet, the Swedish organisation that takes in dogs needing a new start and rehomes them. It wants to know how AI and blockchain can make giving more transparent and more engaging, particularly for younger donors.

What teams are asked to build

The brief names several directions: donation tracking on the blockchain, transparent use of funds, gamified donor engagement, digital rewards and community participation, and dashboards showing impact.

Underneath the list is one requirement. A donor should be able to follow a contribution from the moment it leaves their account to the point where it does something, in real time, without taking the organisation's word for it.

Why this one is different from the first

The first problem statement, from AI Institutet, was about proving a record has not been altered — a technical trust problem. This one is about trust as an experience. The infrastructure question is similar, but the test is whether an ordinary donor feels differently about giving, not whether a cryptographer approves of the design.

Problem statements are released one at a time ahead of the event, which runs 7–11 September in Stockholm as part of Nordic Tech Week 2026.

Applications are open.
