How can we utilize transaction metadata to solve real-world problems?
Transaction metadata means Cardano can be used as a network to store small proofs of events or documents. In the past, this has been used to implement product anti-counterfeit solutions and traceability solutions. And smart contracts are not needed for this functionality. This challenge invites participants to propose prototypes to utilize metadata to solve real-world problems, with these prototypes presented to the Catalyst community at any of the town halls.
