Logosphere - dApp Hackathons

Schema generated business domain model w/native temporal state management in the Logosphere L2 sidechain backed by FlureeDB + [HACKATHONS]

Michael Yagi: ex-Tableau

Dmitri Safine: ex-Amazon

Manik Jain: ex - Tata Consulting

+ 2 Sr. Software Engineers, ex - Fortune 500 companies

This proposal is part of Logosphere (https://logosphere.io) - a Layer 2 metadata side-chain backed by Fluree - an open source decentralized semantic graph database; the initial proposal for which has been funded in Fund 5.

Problem Statement (continued):

Technical Problem:

If you've been a Java or Full Stack developer for a while, you definitely should have encountered various data persistence frameworks, such as Hybernate or Sequelize? If yes, then you should be familiar with the problem they are solving: to make sure that you work with higher level business entities when developing your application, and not spend too much of your valuable time manually crafting SQL queries, transaction statements or stored procedures directly against the database. However, these solutions are typically for relational databases and are centralized.

That is where Fluree, a semantic graph database, is perfect for, but there is a bit of a learning curve to understand all the concepts and start using it in your application. We'd like to facilitate Fluree adoption for you by creating a business model generator that will scaffold a dApp project customized to your business domain - we are calling it Logosphere.

Additionally, you can only interact with the data layer through one direction - traditional APIs / endpoints. You cannot interface with it through the other direction which is the smart contract.

The other part of the problem arises as the Ecosystem Problem:

Even if a project manages to deliver, it can be hard to incentivize developers to try using your product or platform. Growing adoption and awareness of your tool is paramount to collecting feedback and improving your platform. As it stands, there is no guarantee that developers will give what you've been working on a shot.

Describe your solution to the problem (continued):

Technical Solution:

Summary:

• NPM library that bundles all Fluree benefits of decentralized graph databases and their paradigms into one package
• Plutus/Marlowe library that allows developers to interface with their off-chain data layer in their smart contracts themselves

A Developer Flow will be condensed into:

• You spend time where it counts and focus efforts thinking about your business domain, defining entities and their properties, constraints and constraint patterns
• You provide a list of samples for each property of each entity in your business domain
• You create this business model as JSON schema in some graphical editor (we recommend Hackolade)
• You install Logosphere libraries from NPM, run the code generator initializing your DApp application and in 30 seconds you have the following:

1. Fluree DB running on your local machine with a ledger schema corresponding to your business domain and loaded with sample data generated from the JSON schema
2. Generated TypeScript interfaces
3. Base class that handles all the persistence and state management in Fluree DB
4. Business entity classes with getters and setters mapping to other entities according to the structure in JSON schema
5. Func stubs for writing custom code, without touching generated classes
6. Resolver stubs for GraphQL API interface
7. Validator that validates your entities against JSON schema
8. Haskell library with type classes and functions to store offchain data required by smart contracts in Logosphere
9. Marlowe TypeScript library with your business domain entities

Doable? We believe yes! (To tell you the secret, we've been already actively working on a product which will serve as a prototype to the logosphere ecosystem!)

Ecosystem Solution:

We've been working hard the last several months on our solution and using it in our internal product, and once we wrap it up, we will be opening the doors for all to join our two Hackathons for $25,000 in prizes:

• Logosphere API Hackathon: Create a dApp with Logosphere API
• Logosphere Smart Contracts Hackathon: add smart contract functionality with Plutus and Marlowe to your previous hackathon solution

More hackathon details will be released via our socials and through catalyst channels as we develop the schedule and format. Stay tuned for details! Note: team members will be allowed to participate, but exempt from winning any of the awards.

High-level Deliverables (see defining success below)

• Logosphere TypeScript business domain model generator for GraphQL API
• Logosphere dApp hackathon (front end + API, no smart contracts)
• TypeScript business domain model generator for Marlowe
• Haskell type classes and functions generator for Plutus
• Logosphere Smart Contracts Hackathon (add SC to your previous Hackathon solution)
• Documentation and training materials

Budget Breakdown:

Development: ($70,000)

• Blockchain / Full Stack Developer ($35,000)
• Haskell Developer ($35,000)

The team has quit their jobs and since founded https://ikigaitech.org to pursue their passion of developing decentralized technologies on Cardano and Fluree and have been working hard the past few months. While we are mostly self-funded and special thanks to Catalyst community for our Fund5 proposal funded (Graph DB Sidechain with Fluree), development cost is expensive! We are in the process of bringing on a lead software engineer to help with this effort to continue the great work that Fluree recognized us for which lead to an official partnership :)

Hackathon: ($27,500)

• Marketing / Hackathon Organization ($2,500)
• Extensive Documentation and Training Materials both internal and outsourced ($5,000)
• Hackathon prizes ($20,000)

While there is still more to be built, we are proud of what we have been working on and are eager to get it out there to the community and see what everyone comes up with. In order to facilitate a smooth and successful hackathon, we are making sure to reserve funds for prizes and perhaps even more importantly, creating good documentation, support, and organization for a fun experience for the community!

Floating: ($2,500)

• Any unforeseen expenditures to ensure smooth hackathon and development experience

While we like to think we have most of our cases covered, there's no harm in reserving a small floating pool in case of a rainy day. If we ship without touching these funds, they will go back to the community in the form of hackathon reward money.

Total: ($100,000)

KPIs:

• # of libraries downloads
• # of views of download and views on training materials
• # of hackathon participants
• # of dApp created
