# zuCoffee V0.2: Cypherpunk again
## Background
After thinking and organizing a version before in 2023, which counts as version 0.1, I'll make a version 0.2 this time. Inspired by this article:

I happened to have seen CypherPunk again, and was somewhat touched by why we in the crypto industry don't embrace crypto payments, even if it's just a simple cup of coffee. The previous thinking was also based on this logic, this time iterated a bit.

## Program

At ETHPanda Space on Chiang Mai Nimman road, since CMUBA is also helping with some of the day-to-day management and sharing, it was decided to do a prototype based on this space: mobile payment ERC20 for a cup of coffee.
And we plan to get **a mobile ZuCoffee** in Devcon, Edcon, Devconnect and ETHGlobal or more Ethereum events, just put the ERC20 into real life.
This workload is actually very large, so we plan to apply for some funding from both Four Seas and ETHPanda to complete the following plan, also will try to apply fund from zuzalu grant.

### Development
1. develop a user authentication login system based on zupass to log into the community
2. develop a community identity system, currently based on community-issued (purchased) NFTs and account bindings
3. develop the community's task publishing and points system, including submitting tasks and reviewing and witnessing them
4. develop points (ERC20) based on the purchase, the current plan is to log in on the page (not very convenient) and mobile apps
5. above, all code open source, MIT (or GPL)
### Operation
1. buy a coffee machine and hand brewing tools (to learn street coffee)
2. Purchase a certain amount of coffee beans and other consumables, and other items (tables and chairs, etc.)
3. points currently recognized: 4Seas and Panda points
4. Hire part-time Thai students, arrange business hours and open for business!
5. Invite 4Seas and Nimman Road Space to come and try it out.
6. Private business first, if there is a need for business formalities and so on.
### Time
1. Zupass two weeks: one week integration, one week debugging the most basic community page
2. Email binding contract account has been completed, but to be integrated with zupass, 3 days
3. task issuance and points system, task collection and submission, verification (manual if no time), one week design, two weeks development, including integration with zupass
4. NFT customized distribution and selling, two to three weeks, need to complete both web and app version, this need to pay USDT or stablecoin.
5. Coffee purchases (QR code scanning), fingerprint verification of cell phones, payment of ERC20 points (only Zuzalu, 4Seas, ETHPanda are recognized at the moment).
6. Use some components, thanks to **Proof Carrying Data(zuPass)，AAStar(ETHPaymaster, AirAccount) and CMUBA(HexzgonWarrior)**.

**Total 2 month to deliver**
