Create a end-user facing demo decentralized application, dapp, on top of Linnia Smart Contract

[godfreyhobbs]

Gitcoin Funding Amount: 0.7 ETH

Context

Linnia is a core component of the future of the web; Web 3.0. Linnia is a new Ethereum Blockchain protocol that brings the power of decentralization to your lifetime data. The Linnia protocol provides the foundation for secure decentralized applications in multiple spheres including the sphere of electronic healthcare records.

What

We would like to incentivize you, as a member of the Gitcoin/Bounties family, to create a new end-user facing demo decentralized application, the dapp, on top of Linnia Smart Contract. We will be awarding the best submission for this task a .7 ETH prize, assuming the below requirements are met.
The dapp must be in the spirit of the following two Linnia papers;

1. https://github.com/ConsenSys/linnia-resources/blob/master/Technical-Whitepaper.md
2. https://github.com/ConsenSys/linnia-resources/blob/master/Introducing%20Linnia.pdf

Note: Linnia is a WORK IN PROGRESS. The Linnia smart contracts are only a small subset of what is described in these papers.

Our Ideas

1. Share the answer to riddles with friends via the smart contract permissions
2. Upload and share data from a fitness tracker API such as the Fitbit API

Requirements

1. You have read and understood the WIP nature expressed in the README.md
2. Code must be in a public github repo
3. Use the Linnia Smart Contracts for some non-trivial end-user facing functionality
4. Consider use of encryption to keep data secret
5. Be prepared to present your submission to the linnia team
6. Be prepared for a review of your code by the linnia team
7. Open source your solution
8. Finally, use your imagination

Q: Any specific style guide or front-end framework to use?

A: First of all, there is no requirement to submit a web app

However, if you are building a web app then we like the following:

1. React / redux
2. material ui (e.g. https://material-ui-next.com/)

Added Linnia changes that would enable deeper integration section:

Linnia changes that would enable deeper integration

• The extended use of msg.sender in Linnia, to identify who makes the change, doesn't scale well, when a single caller contract does the changes (in my case MapDomain). There could be a better way to register signatures for people and the ability for a single Provider to sign multiple times (ideally it would allow me to implement the state machine, I use used for). Also self-registered people (Patients) should have some provenance (see next).
• I would like to map the price to irisScore, but there's not fine-grained control of provenance yet.
• Accessing FileRecord values through records, is incomplete because of the mapping to tuple, the default getter does. Now I have to use (patient, sigCount, irisScore, recordType, ipfsHash, timestamp) = hub.recordsContract().records(resourceId) but this means that a) I lose signatures, which might be ok, but also b) if the order changes there might be a problem.
• I would like to map endpoint to some userdata in FileRecord. It could also be stored in metadata somehow.
• I now have my own metadata structure. Metadata (both Contextual and Quality) as described in Data and Metadata sound like exactly what I try to do with that data structure. If we were generalising to create a News Portal (see below) such metadata would be the taxonomy of the article as well as the teaser (thumbnail and first few lines of the text).

Note that the theme here is, in general, generic web content "gating" by using single-use URLs that consume credits as you browse. It's easy to adapt the code of Zelp to create e.g. news portals or forums, where the visitor adds Ether and then browses the metadata (teaser) of the content and has to make micro-payments to access gated content. Further roles and access control (by mapping and extending the Patient/Provider roels) can enable/disable and rate content as e.g. Editors, moderators etc.
