On March 3rd, during the latest CityCoins Builder Showcase:

Hosted by CityCoins Community Lead Andre Serrano, highlights are below.

CityCoins API & “Proof-of-HODL”

CityCoins Core Developer Jason Schrader demonstrated how the CityCoins API makes it easy to develop use cases like “proof-of-HODL.” Jason even turned on his webcam to demonstrate how QR codes could verify a user’s wallet for access to a space.

“Everything is super simple... you'll notice we have less than 100 lines of code here, if you ignore my fancy comments.”

CityCoins NFTs

Jamil Dhanani presented updates on CityCoins NFTs on an NFT marketplace on Stacks, secured by Bitcoin. The project was founded following NFT donations to Miami’s MiamiCoin treasury.

“I noticed the MiamiCoin wallet owned NFTs. People were sending them, but there was no way to see them… we’ve been pushing the intersection of CityCoins and NFTs ever since.”

The first NFTs minted by MiamiCoin (MIA) were released in September, 2021. Now anyone can create NFTs using their CityCoins.

“It’s not about the platform—it’s about supporting the artists and local communities to make it happen.”

Diego Mey shared the latest on CityPacks: NFTs that fund and empower public school students. CityPacks mission is to sustainably educate and empower today’s public school students using crypto. Each CityPacks NFT donates 75% of primary sales plus 4% lifetime royalties to Foundation for New Education Initiatives.

CityPacks are Diego’s answer to how DeFi can help public institutions like schools in perpetuity. Utilizing an “open-source educational platform,” CityPacks sales fund the development of a Blockchain & Cryptocurrency Program (K-12), The Cultural Passport Program, Mini Grants and more. Distributing yield and interest further compound the possibilities for perpetual support.

“This will be our first full-blown funding campaign to support public school students.”
