HEDUS: Blockchain education for K-12 students

How important will blockchain be for Generation Z? On the one hand, many experts say we’re still years away from buying coffee with Bitcoin. On the other, China continues full steam ahead on their national cryptocurrency. While there’s still uncertainty about when blockchain will enter our daily routine, there is little doubt that it will.

The next question is, how should K-12 teachers introduce blockchain to their students in 2020?

Hedus: Privacy Coins for Classroom Management

Manaus is the capital of Amazonas, a Brazilian state deep in the heart of the Amazon Rainforest. Despite a population of nearly 2 million, Manaus has largely missed the blockchain revolution taking place in Brazil’s coastal states. David, a school teacher and early crypto investor, felt that blockchain education was important for his primary and secondary school classes. He devised a plan to teach his students about blockchain and tokens in their extra course time – “kinda like extracurricular activities.”

“When my students do a good thing and it is confirmed by me, I send them a Hedus.”

David created a Privacy Coin on Incognito called Hedus (HEDUS) as a way to reward students for good behavior. In his own words, “Hedus is something opposite to Judas, and it is quite close to Jesus…When my students do a good thing and it is confirmed by me, I send them a Hedus…Every week, students must have more then 10 Hedus to prove they have been a good student for the whole week.” At the end of the semester, the student with the most Hedus gets a trip to São Paulo, Brazil’s bustling capital.

As of the time of this writing, there have been almost 1,000 transactions of Hedus, and almost 90% of transactions were between students. Says David, “I think my students also send Hedus to each other to help them reach the standard amount of Hedus each week. The network effect has worked.” He credits Incognito’s ease-of-use for the quick adoption rate: anyone can create an account in seconds, transaction fees on Incognito are very low, and students simply scan QR codes to exchange tokens.

“The network effect has worked … it’s just fun for them!”

David chose Incognito for two reasons: privacy, and ease-of-use. Before Incognito, he used WAVES, a platform for issuing custom coins and low fees, but students were able to see each others’ score. He found Incognito through its partnership with Harmony ONE, and was impressed by the ease of creating custom Privacy Coins, and the user-friendliness of the app. “With Hedus, they only need to scan the QR … they see their Hedus amount change, and it’s just fun for them!”


David was able to spark an interest in blockchain in his primary and secondary school students, while also promoting good behavior and demonstrating how privacy is important on blockchain. How did he do it?

  1. Download the Incognito Wallet  (Google Play or Apple App Store)
  2. Issue a custom Privacy Coin on Incognito
  3. Have all students download the app
  4. When students behave well, send them a Coin
  5. Teach students how to exchange Privacy Coins with each other
  6. Discuss the advantages of public ledgers vs private ledgers
  7. At the end of the period, check each students’ Coin Balance

And finally, the whole process is enjoyable for the students. According to David, “I think it is just a cool game for the kid to play with something like digital wallet.”
