Q&A Highlights

The meetup included a lively Q&A segment, where participants clarified key concepts and asked about practical use cases.

Questions:

  • What’s the difference between a payment address and a stake address in Cardano?
  • How are token policy IDs used to verify authenticity of tokens and NFTs?
  • If a token is sent to the wrong address, is it possible to reverse the transaction?
  • Can I mint multiple types of tokens in a single transaction?
  • What is the best practice for managing keys securely when working with CLI?
  • Are there testnet explorers to check transactions after using CLI?

These questions showed that participants were not only following the technical steps but also thinking critically about real-world applications and security practices.

Community Learning Experience

As with previous meetups, the session was both educational and collaborative. Participants shared screenshots, asked for feedback, and helped one another troubleshoot during the hands-on practice.

The Cardano Builder Vietnam Telegram group remained active after the session, where attendees continued sharing progress and clarifying doubts.

Thanks & See You Next Time

Cardano Builder Meetup Online #4 helped participants gain confidence in working directly with the Cardano blockchain via CLI. Each topic brought them closer to becoming self-sufficient builders.
