In this episode, we spoke with Adri Wischmann, founder of PBToken and IoT Nederland. Adri shared his journey from the financial sector to IoT and blockchain, detailing how he drew inspiration from his grandmother’s multi-compartment wallet to create the "knip" wallet—a blockchain-based solution for managing purpose-bound money. He highlighted real-world use cases, including the EnergieKnip project, which incentivizes energy savings through blockchain rewards. Adri also discussed the social and environmental impact of blockchain, particularly in helping low-income households and promoting sustainable living.
