Track1: Use OKP4 blockchain governance rules capabilities to enhance the Cosmos ecosystem

Get to know OKP4 and the logic module

OKP4 blockchain has a special "logic" module built-in, which enables Prolog rules evaluation. Prolog is a perfect language to define governance for DAOs and more; it allows way more expressiveness than you could define with CosmWasm and others. The "law-stone" CosmWasm smart contract deployed on OKP4 leverages the logic module.

Challenge

Enhance existing CosmWasm smart contracts tied to governance and consent rules to provide relevant new features that can only be possible using Prolog language:

  • accounts whitelisting related to cross-chain addresses and decentralized identifiers (DID)
  • variables from data stored in an object storage smart contract (OKP4's "objectarium")
  • ... and anything you could have in mind!

Requirements to win

Your project should provide a working proof of concept interacting with a "law-stone" instance deployed on the OKP4 testnet.

Although you can adopt any implementation, we would highly appreciate it if you:

  • Use NYMLAB's Vectis and link guardianship to Prolog rules.
  • Extend DA0-DA0 smart contracts with advanced governance rules, especially for voting powers

Track2: ABCI++ Track

Background:

The Cosmos SDK and CometBFT are at the center of Cosmos. The Cosmos SDK provides a toolkit for building modular, scalable, and interoperable blockchains, while CometBFT provides a consensus algorithm that is secure and efficient.

The newest releases of the Cosmos SDK (0.50) and CometBFT (0.38) introduce a number of new features and improvements, including support for ABCI++. ABCI++ is a new interface between the Cosmos SDK and the application state machine and has introduced new functionality such as Vote Extensions.

This hackathon is an opportunity for builders to explore new and innovative use cases for ABCI++. We are looking for applications that:

  • Leverage the new functionality of ABCI++ with Vote Extensions.
  • Use ABCI++ in innovative and creative ways.
  • Are well-designed and implemented.

We encourage participants to think outside the box and to come up with new and innovative ways to use ABCI++. We are particularly interested in applications that can benefit the Cosmos ecosystem, but we are open to all proposals.

Bounty: Abstract SDK Bounty

Cw-orchestrator

CosmWasm Orchestrator (cw-orchestrator) is an environment-agnostic CosmWasm scripting library. It enables developers to use the same Rust code to write mock and e2e integration tests and deployment scripts. It also significantly reduces and simplifies the syntax required to perform those tasks.

Challenge(s):

  • Write integration tests with cw-orch using the Mock environment which is an IBC-enabled cw-multi-test mock environment.
  • Develop integration tests using the Osmosis test-tube environment which allows for executing Stargate messages.
  • Deploy your contracts to local, test, or mainnet chains using the Daemon environment.
  • Use cw-orchestrator’s IBC features for CosmWasm IBC development. (free beta available)
  • Publish a crate with your interfaces and deployment logic for use by other teams.

About Abstract SDK

Abstract is an interchain application platform built to allow developers and startups to collaborate better and write more scalable, robust, and advanced smart-contract applications. We provide a selection of application development tools, including:

  • Smart-contract framework & on-chain infrastructure (Abstract SDK)
  • Development tooling (cw-orchestrator)
  • Front-end libraries (Abstract.js)
  • Developer Console (Abstract Console)

First and foremost, we provide a smart-contract framework with conventions to build applications “modularly,” which means that as a dev, you can use modules and integrations published by other teams and focus directly on your business logic.

Once deployed and published, applications are available on the app store on the Abstract Account Console, which will be available to users across the interchain.

Overview of the Abstract Platform

The Abstract platform is currently deployed on Neutron, Juno, Terra, Archway, Sei, and other CosmWasm chains are a simple deployment away.

Challenge Description:

Develop a modular application using Abstract SDK. Some application ideas can be found here. We encourage developers to combine this challenge with the other CosmWasm challenges such as Neutron’s, Akash’s, and/or Nibiru’s.

Challenge Objectives:

  1. App Module: Develop an app module(s) that contains the business logic for your application.
  2. Inter-Module Interaction: Leverage other modules available on the Abstract platform like the Dex and Cw-Staking contracts.
  3. Deployment: Deploy your application using cw-orchestrator and Abstract’s deployment helpers.
  4. Frontend: Craft a frontend to interact with your application.

Bounty: Nibiru Chain: DeFi Money Legos

Challenge:

Nibiru invites Hackmos participants to build DeFi Money Legos, either as dApps or dev tools for other projects, leveraging CosmWasm and Nibiru.

Project Ideas:

  • Prediction Markets: Build a platform for users to bet on future events from the Nibiru blockchain by buying and selling fungible tokens that represent the probability of certain outcomes. Odds will then be determined dynamically based on the supply and demand of the probability shares. This could leverage x/oracle and should support creation of arbitrary markets.
  • Synthetics: Build a decentralized liquidity layer based on synthetic assets that can be composed with dApps on Nibiru and other chains in the IBC ecosystem. This would likely leverage Nibiru’s Oracle Module to allow the creation of synths for arbitrary assets by pulling data from off-chain APIs.
  • See the full RFP List for more info.
  • Index Tokens: Construct a platform that allows users to create and manage indices of popular cryptocurrencies, yield-bearing assets, or RWAs (stocks, commodities, etc.).
  • Mobile Tool/App: Build a tool to see asset performance, analytics, user portfolios or other data from a mobile device.
  • Oracle Infra: Add new data sources to the NibiruChain/pricefeeder, or add interesting data feeds that other dApps could build upon. For example, a data feed for random/pseudo-random numbers that can be queried in CosmWasm could facilitate gaming dApps. This sort of infra is available on Ethereum, but it’s a missing piece on Cosmos.
  • Lending & Borrowing: Build a platform that enables crypto-collateralized lending and borrowing on Nibiru. Allow users to deposit supported assets as collateral to take out loans in stablecoins or other assets. Interest rates can be determined algorithmically based on utilization. Feel free to explore features like fixed rated lending, flash loans, or undercollateralized loans for whitelisted borrowers.
  • IBC Integrations: Develop ways for users to seamlessly leverage the utility and shared liquidity of CosmWasm-enabled chains. This integration would be between Nibiru and chains like Neutron, Osmosis, Sei, Terra, Injective.
  • Flex: Feel free to propose and build outside of this project idea list if it seems relevant.

Submission Guidelines:

  • Projects should be open-source, have a detailed README, and usage instructions.
  • Include a short demo of some kind, whether as a video or in a well-prepared written format.
  • Make the smart contracts runnable against a local instance of the chain, OR deploy the contracts on testnet.

Judging Criteria:

  • Execution / Functionality
  • User Experience, Developer Experience, Documentation
  • Impact
  • Creativity / Innovation
