Tuesday, 16 September, 2025

In this episode of 10,000 Satoshis, joeFi sits down with Justin, an open-source developer contributing to Fedimint. Together they break down what federated e-cash is, why it matters for Bitcoiners, and how it balances privacy with ease of use. Justin shares his journey from working at Microsoft to becoming a full-time Bitcoin developer supported by open-source grants, and how the Minneapolis BitDevs meetup has grown into a thriving technical community.We also dive into Justin’s latest project—the launch of the E-Cash App—a new wallet that supports Lightning, on-chain Bitcoin, and e-cash with features like Nostr Wallet Connect and Lightning Address integration.
