STARPORT PRIZE: STARPORT IMPROVEMENT

OVERVIEW: STARPORT IMPROVEMENTS

Starport is the all-in-one platform to build, launch, and maintain any crypto application on a sovereign and secured blockchain. Starport CLI is a powerful developer tool for scaffolding blockchains, generating code, running a node in development, and much more. Builders will need to implement new scaffolding functionality or improve the functionality, reliability, or flexibility of Starport CLI or introduce new functionality that is useful for a large number of developers

 

STARPORT PRIZE:  CHALLENGE STARPORT - CODE SCAFFOLDING 

One of the core features of Starport is code scaffolding. Starport can scaffold a new blockchain from scratch, create new modules, add messages, queries, packets to modules, and much more. This functionality allows developers to prototype advanced modules with just a few commands. Currently, Starport depends on string placeholders being present in modules’ files. Placeholders work, but if another solution (likely, based on code analysis) is found, this could improve Starport's reliability even further.

 

REQUIREMENTS

  • Reengineer Starport’s code scaffolding to avoid relying on placeholders as much as possible

  • There should be no placeholders in proto files

  • The goal is to make Starport more resilient and less fragile

  • Solution should gracefully handle if required files are not found

  • Use Starport's list as an example command to showcase functionality

  • Try keeping backwards compatibility with Starport v0.18

 

___________________________________________________________________________________________________________________________________


STARPORT PRIZE:  CHALLENGE STARPORT - LOCAL TESTNET

Starport chain serve is the most convenient way to start a blockchain node for development purposes. Currently, this command sets up a single node testnet with automatic code reloading. Enhance this functionality of Starport, for example, to support multi-node local testnets.

 

REQUIREMENTS

  • The enhanced version of serve should support existing features of Starport (for instance, code reloading)

  • Multi-node testnet is just an example, find other creative ways to improve developer experience

  • Command shouldn’t require flags to run, but you can use the config file to customize its behavior

  • Try keeping backwards compatibility with Starport v0.18

 

___________________________________________________________________________________________________________________________________
 
STARPORT PRIZE: CHALLENGE STARPORT - BUILD PROCESS AND CONFIGURATION

Starport uses an advanced build process to compile the source code of a chain into a binary. It’s both sophisticated and easy to use, but there is always room for improvement. To win this challenge, enhance the build process so that it’s more flexible, yet can be used even by beginner developers.

 

REQUIREMENTS

  • Do not rely on Makefiles. Makefiles are very flexible, but this flexibility makes it harder for us to control the build process (for example, we can’t know the name of the binary produced by make). Instead, consider using config.yml to customize the build process. For inspiration: goreleaser, taskfile, etc.

  • Add customization options declaratively, like toggling support for Ledger devices, passing flags, etc.

  • Think of other config.yml improvements that can enhance the developer experience.

 
___________________________________________________________________________________________________________________________________
 
STARPORT PRIZE:  CHALLENGE STARPORT - A PLUGIN SYSTEM

All of Starport’s functionality right now is implemented in packages within the Starport code repository. From a maintenance perspective this is convenient, but a program like Starport can definitely benefit from a flexible plugin system that will allow developers to add functionality to Starport on-the-fly.

 

REQUIREMENTS

  • Each plugin is a Go Plugin, and hosted in a repo. There can be multiple plugins inside a single repo.

  • Users will need to add their desired plugins to their config.yml in the new plugin section.

  • A plugin needs to comply a certain interface defined by core Starport developers.

CONSTELLATION PRIZE : ETHEREUM ON COSMOS 

OVERVIEW: ETHEREUM PROJECTS ON COSMOS SDK 

On blockchains, the goal of smart contracts is to simplify transactions between both anonymous and identified parties. Smart contracts are executed when predetermined conditions are met, such as the fulfillment of an agreement or completion of a task. Smart contracts are typically used to automate the execution of an agreement so that all participants can be certain of the outcome, without depending on any intermediary involvement. Smart contracts that currently live on the Ethereum Virtual Machine (EVM) are written in Solidity. Developers will explore among others rewriting an existing Solidity project as a Cosmos SDK blockchain that automates transactions on the blockchain or any other dedicated solution that could bridge the two ecosystems.

 

CONSTELLATION PRIZE: CHALLENGE BITSONG

BitSong is a project dedicated to musicians and their fans that aims to overcome the bureaucratic and economic obstacles within this industry and reward artists and users for simply using the platform. Bitsong's HackAtom VI challenge proposes the migration of smart contracts on the popular OpenSea (https://opensea.io/) NFT marketplace to Cosmos SDK. Participants should use the new NFT module that BitSong developed for its own blockchain, which contains an extraordinary feature—the introduction of perpetual royalties (a new standard for splitting royalties). Specifications can be found here. 


In addition to BitSong's NFT module, there is an Auction where users can buy and sell their NFTs through a marketplace, providing participants with everything they need to bring Ethereum-based NFTs to Cosmos. Specifications can be found here.

 

REQUIREMENTS

  • The module development must be done using Golang.

  • Participants must follow the basic specs as per every Cosmos SDK module development.

  • The module is expected to be completed during the HackAtom, otherwise at least an MVP with integrated tests and CLI (even without UI) is required.

  • The module has to be importable to all ecosystem chains.

  • The NFTs Auction must respect the royalties system present in BitSong's base module.

 

SOURCES

The source code and the whole ecosystem is available on Github:
https://github.com/ProjectOpenSea

https://docs.opensea.io/

BitSong's Developer Portal can be found here:

https://btsg.dev/

The module must be created from scratch.  A simple gaia local chain or a simple bitsong local chain can be used  https://github.com/bitsongofficial/go-bitsong/tree/v0.8.0

https://github.com/bitsongofficial/go-bitsong/tree/hackatom/nft

CONSTELLATION PRIZE - CHALLENGE EVMOS

Evmos is an application-agnostic chain that will be interoperable with the Ethereum mainnet, EVM-compatible environments, and other BFT chains via IBC, making it easy for users and developers to interact seamlessly between chains. Evmos aims to be the EVM Hub of Cosmos, making it easy for smart contracts to deploy and communicate within the Cosmos ecosystem.

 

To jumpstart the growth of the Evmos ecosystem, we have created a helpful list of topics that could be eligible for the Evmos prizes during HackAtom VI:

  1. NFT: Build an NFT smart contract project, Marketplace (dApp), or other supportive tooling (e.g. NFT fractionalization, rentals, etc.) to support the burgeoning NFT ecosystem on Evmos. Judges will be looking for projects with a usable UI and broad support for multiple Ethereum NFT standards.

  2. Wallets: Build an EVM+Cosmos+IBC-compatible wallet that integrates Evmos’ JSON-RPC and gRPC services and is able to display ERC20 tokens, Cosmos coins, and IBC vouchers. Bonus points: Multisig support, WalletConnect V2 support.

  3. Dashboards and Visualizations: Build a block explorer for displaying Cosmos data alongside EVM data (transactions, blocks, etc.). Judges will be looking for projects that push the envelope on “seamless cross-chain UX."

  4. EVM DeFi: Port an existing open-source DeFi smart contract project or build and deploy your own DeFi smart contract application onto Evmos. As with the NFT challenge, your smart contracts must have a usable UI. Support integrations with as many other projects as possible for maximum consideration.

  5. IBC-EVM interoperability: Build an IBC SDK application module to be deployed on Evmos, that is able to handle EVM or smart contract interoperability between two connecting chains that integrate the Ethermint library’s EVM module. The module should be able to process cross-chain contact calls.

  6. Cross-chain (Ethereum/EVM) challenge: Port or build an EVM bridge and deploy it on Evmos so that Ethereum assets (ERC20, ERC721, ERC1155) can be bridged to the Evmos EVM and vice versa.

 

REQUIREMENTS

  • Solidity or other smart contract languages (Vyper, Fe, etc.)

  • Ethereum tools (Hardhat, Truffle, Remix, etc) and libraries (web3, go-ethereum, ethersjs, etc.)

  • Evmos JSON-RPC and gRPC services

 

STAGE OF DEVELOPEMENT

Evmos is currently in testnet with additional functionality rolling out over time and leveraging the upcoming features of the testnet and incentivized testnet will have an added bonus.

The applications submitted must have had the significant majority of its development done after the date of the initial Evmos Arsia Mons testnet launch (Oct 12) as verified by Github commits. If you used a previous project as a starting off point, you must detail which components you developed during the hackathon (Nov 11-Dec 8).

Projects must be deployed on a live Evmos testnet (Incentivized testnet or Arsia Mons) by the end of the hackathon on December 8, 2021.

The projects MUST follow the following checklist to be eligible for the prizes:

  • Open source, deployed on Github or Gitlab

  • Have a working UI (if applicable)

  • Have a working functionality

  • Clear documentation in the form of a README.md, for how to interact and run the project

INTERSTELLAR PRIZE : INTEROPERABILITY

OVERVIEW: IBC Use Cases

Alongside the Tendermint high-performance Byzantine fault-tolerant (BFT) consensus engine, one of the main innovations of the Cosmos Network is the robust and secure Inter-Blockchain Communication protocol (IBC), the Cosmos standard for interoperability. This protocol enables communication and digital asset transfers across an ever-expanding network of interconnected blockchains. Developers will need to create new, innovative ways to highlight the possibilities of blockchain interoperability using the IBC protocol such as viable implementations, use cases, data formats or others.

 

INTERSTELLAR PRIZE : CHALLENGE AKASH

Censorship-resistant, permissionless, and self-sovereign, Akash Network is the world's first open source cloud. One of the biggest values that Akash can provide to other blockchains is the ability to run hard-to-deplatform durable blockchain nodes. Removing blockchains' dependence on centralized hosting providers is one of the biggest steps blockchains can take toward further decentralization. To this end, the Akash community and core developer team have put together the following GitHub repo:

https://github.com/ovrclk/cosmos-omnibus  

 

This repo contains the deployment scripts and references to working images to deploy nodes on a number of different Cosmos chains in a matter of seconds. Akash's HackAtom VI challenge asks participants to develop the container images, SDL files, and readme.dm documentation needed to run chain nodes from Cosmos chains that are not currently in the repository. Deliverables will be in the form of a PR to the https://github.com/ovrclk/cosmos-omnibus repo.

 

REQUIREMENTS

Deliverable must include the following:

  • Configured SDL for deployment 

  • Working container image

  • Complete documentation in the form of the readme.md

  • Working Github account for the pull requests

  • Access to the internet for the deployment and testing of the image on the Akash network

INTERSTELLAR PRIZE : CHALLENGE SENTINEL

Sentinel is a network of independent dVPN applications, not just a single consumer-facing dVPN. Sentinel's IBC challenge is a tough one to tackle but could help to solve an important problem in the wider Cosmos ecosystem. Participants must build a fast, reliable, and unbiased randomness generator which could ideally be used for validator selection. 

 

A randomness generator will be very useful for many other applications, from consumer-level apps to DeFi protocols, and Sentinel believes that the Cosmos Hub would benefit heavily if it could provide on-demand randomness through IBC.

 

REQUIREMENTS

  • Submissions must use a Cosmos module and integrate with the chain as low-level as possible, ideally able to be integrated in the core Cosmos SDK.

  • Tools/Framework - any

  • Development phase - at least a Proof of Concept with a realistic actionable plan of implementation based on the DFINITY solution

INTERSTELLAR PRIZE : CHALLENGE SIFCHAIN


Sifchain is a robust, Decentralized cryptocurrency exchange (DEX) for executing cryptocurrency transactions across chains. Earlier this year Sifchain launched its Betanet with a live DEX and cross-chain support to the Ethereum network, allowing users to swap Cosmos and Eth tokens on the same DEX. Sifchain proposes the following challenge for submission to the Cosmos HackAtom contest:

 

PROJECT GOAL

Exchange crypto currencies regardless of the underlying blockchain or token.

Sifchain’s goal is to become the leading omni-chain DEX, with flexible trading capabilities across dozens of the top blockchains.

 

COSMOS GOAL

Accelerate the pace adoption for new chains and tokens by making them discoverable to 3rd parties.

When a new Cosmos project is launched it takes time for the project to build an audience and encourage use. Projects building on the Cosmos SDK would benefit greatly from automatic chain and token listings. Automatic advertisement and listing of new tokens and chains allow new projects to list on DEXs without requiring project engage one-on-one.

 

SUBMISSION PROPOSAL

Implement IBC chain name and metadata synchronization service as a Cosmos IBC module.

With the inception of Web 1.0 came IP addresses: strings of numbers which were useful to engineers but useless for the vast majority of users. The invention of DNS (domain name service) enabled users to easily identify a valid server without the need to maintain a client side list. Similarly, this project aims to enable users to easily identify a valid IBC client and its tokens without the need to maintain a client side list of chain id’s, channel id’s, connection id’s, and token denom mappings.

 

Secret Network has a variety of different tokens, each with their own name, display name, image url, precision etc. Imagine that Secret Network connects to Sifchain, as it will in the near future. Sifchain users transfer over Secret tokens. Currently, these tokens are useless because they still need to be added to a frontend asset whitelist (e.g. https://github.com/osmosis-labs/assetlists or https://github.com/Sifchain/sifchain-ui/blob/develop/ui/core/src/config/networks/ethereum/assets.ethereum.mainnet.json) or on-chain whitelist (e.g. https://api.sifchain.finance/tokenregistry/entries) before they can be parsed by wallets, apps, exchanges, etc.

 

The first challenge of this project is to sync over the name, display name, image url, and precision of tokens to and from cooperating blockchains, making these tokens immediately accessible to applications built on the counterparty chains.

 

Then imagine someone forks Secret Network, creating Fake Secret Network with indistinguishable copies of all Secret tokens. Then they connect to Sifchain as well. How do we tell the difference between tokens from Secret Network and tokens from Fake Secret Network? 

 

The bonus challenge of this project is to create a governance-driven chain name service that defines which connection chain (which IBC client) is the legitimate one. Once this is complete, chains can update their own token data locally and automatically sync the updates across to counterparty chains.

    • Build prototype blockchain with Starport

    • Golang + Cosmos SDK (.44+)

    • Provide a basic test harness via HTTP

      • If used properly, Starport with scaffold most of this for you
  • IBC Layer

    • Synchronize chain name and metadata across IBC clients

    • For the minimum viable product, IBC client id’s may be hardcoded and this hardcoded list would naturally need approval via a chain upgrade.

  • Governance Layer (bonus)
    • Utilize governance to form a consensus on the canonically identified IBC client for a given counterparty chain from the source chain
  • Web Interface (bonus)
    • A prototype web interface to display how
  • Document the architecture, decisions and build & run steps a README.md at the root of your project

  • Provide a video demo using the product

 

RESOURCES: Tips & resources for a great submission

A successful submission provides sufficient detail of the ‘who, what, when, why, and how’ of the service. The following questions should be considered in the design of the solution.

Who is using the API? When would the API be used? Why does the service need to exist? How does the service address the problem? Does the API appropriately solve the question being asked by why? How does the service benefit the Cosmos community? What happens when the service fails?

SOLAR PRIZE: END USER APPS



OVERVIEW:  CREATE AN END-USER APP

Accessibility is a primary driver to entering the blockchain ecosystem, yet one of the most challenging tasks in blockchain is to make cryptocurrency and digital asset ownership accessible to end-users. Applications should manage keys in a secure manner allowing users to access their assets in an easy way and improving the overall user experience for beginners and advanced users. Developers are expected to build applications that make features more accessible or provide a more intuitive experience for an end-user.

 

SOLAR PRIZE : CHALLENGE NYM

Nym is a privacy platform. The Nym Mixnet provides network-layer privacy for users and applications by hiding the metadata (IP addresses, device types, timings, etc.) of the data packets that are sent through it. Creating a file storage application over the Nym Mixnet will allow users to store files in the cloud in a secure and private manner. The title of Nym's challenge is ‘The Eternity Service 2.0’. 

 

The challenge is to create a Nym service provider (application) which offers cloud file storage, and a GUI where users interact with the service provider, all via the Nym mixnet. 

 

Users must be able to do the following via the GUI: 

  • Store an encrypted file on the service provider: 

    • Users must be able to encrypt a file and upload it to the service provider’s storage via the Nym mixnet. Whether new keys are generated for this encryption or whether the user can import existing keys is up to the developer. 

    • This step will also hash the contents of the file and store the resulting hash in local storage on the user’s machine, and be represented in the GUI.

  • Verify their file has been uploaded and stored:  

    • Users must be able to poke the service provider with the hash of the file they uploaded in order to verify that the encrypted file exists with this hash as its identifier. 

    • If the service provider answers in the affirmative, users should have the option of having their client-side application overwrite the bytes of their local storage where the file is to remove it. 

  • Retrieve their encrypted file from the service provider: 

    • Users must be able to request their file from the service provider using the hash as proof of ownership. 

    • Users must be able to decrypt the retrieved file locally. 

  • Request for the service provider to delete its copy of their encrypted file: 

    • Users must be able to ask the service provider to delete the file it is storing, and verify there is no identifier remaining, again using the content-hash of the encrypted file. 

  • [Optional bonus feature 1] Users are able to securely share the hash & decryption key of uploaded encrypted files with friends via the Nym mixnet!

  • [Optional bonus feature 2] Users are able to choose between uploading private files or public files for archiving: 

    • Users have the option of also uploading an unencrypted file to the service provider.

    • Users can then upload the hash of the file to the Nym blockchain, with plaintext information about what the file is. How this information is best uploaded and stored in the blockchain is left to the developers to decide. 

    • This information is stored in a publicly accessible manner.


A note regarding Nym testnet development: Nym is likely to upgrade to a new testnet and/or to mainnet release during the time period of the hackathon. New networks will require bandwidth credentials to be created and used by both the client-side Nym client and the service provider’s Nym client in order to send packets through the mixnet. Integrating these updates will involve a small amount of extra work, but Nym will offer support by providing any necessary information!

 

REQUIREMENTS

  • Submissions must be usable/workable via the Nym testnet, but not necessarily production-ready.

  • Submissions must include a working service provider and desktop GUI application.

  • No specific language or framework requirements. 

  • Good security practices will be an integral part of the judging criteria.

 

SOURCES

The best place to start is using Nym's network overview documentation. It will also be helpful to look at how Nym's existing network requester service provider is set up in the documentation. 

Further reading regarding each node type in the Nym network can be found here, and a simple easy-to-read introduction to mixnets here. 


For historical/contextual information regarding the title of this challenge, Nym recommends reading Ross J. Anderson’s The Eternity Service.

SOLAR PRIZE : CHALLENGE INJECTIVE

Injective Protocol is pioneering a new decentralized economy to create a freer and more inclusive financial system. Injective has created a solution that allows crypto exchanges to become a decentralized public utility, giving users and their community much-needed value-capture in the exchange landscape.

Injective's HackAtom VI challenge is to build a new simple single-page application trading interface for trading spot and perpetual markets. The purpose of this is to provide mass market users (not pro traders) an accessible, user-friendly interface for trading (Like Matcha on Ethereum, for example). This will allow novice traders to access Injective easily.

On Injective such frontend interfaces are referred to as a Relayer. A relayer is essentially a frontend interface that allows users to interact with Injective Protocol. Relayers are able to earn 40% of all trading fees generated. So if you build a relayer you can continue to earn fees in perpetuity. Relayers come in all forms. Currently there exists a number of different relayers such as Injective Pro and Picasso Exchange. A relayer can include new features and even be region specific (for instance there is currently a relayer being built entirely in Chinese).

The easiest way to get started without worrying about underlying business logic implementations is to fork our [injective-dex](<https://github.com/InjectiveLabs/injective-dex>) repo. This repository already contains two of the three components required for the application. It also has a lot of example usage of our [injective-ts](<https://github.com/InjectiveLabs/injective-ts>) monorepo packages that are used to easily build user interfaces that consume and interact with the Injective Chain.

You can find tips and more details in the following page:

REQUIREMENTS

  • Make a meaningfully unique/better designed product. Submissions that simply restyle a few components will not be awarded.

  • Proper project structure.

  • Clean and readable codebase.

SOLAR PRIZE : CHALLENGE LIKECOIN

 

ISCN is a NFT-like content registry record running on the LikeCoin chain. We allow content creators to register their content metadata on the chain through ISCN transactions. 

Currently, there are three ways for creators to register their content metadata to the LikeCoin chain, 1) register via app.like.co, 2) ISCN batch uploader, 3) LikeCoin Wordpress plugin. Unlike traditional NFT, ISCN owners might have to view, manage or edit ISCN records in batch, since talented creators can produce creative works quickly, and have a huge collection of series of metadata.

In this challenge, we hope developers can develop a wallet interface to allow users to manage their pre-NFT credentials (metadata) records. Useful features include visualization of the metadata records, and organizing them into directories or groups; interface for viewing and editing metadata records, and sending and trading of metadata records (change of owner).

 

REQUIREMENTS

  • Develop a dApp interface for users to view and manage their ISCN records

  • Visualization of users’ ISCN records, allow users to organize their collection in UI

  • Editor for ISCN records, figure out a user-friendly way for editing in batch mode

  • View-only mode to discover contents of a specific address/creator

  • Global ISCN browsers, preferably with a way to discover groups, series, and relationships between works

  • Other features that might be useful for content creators to manage their ISCN records

OVERVIEW: DEFI APP OR MODULE WITH THE COSMOS SDK

DeFi is a blockchain-based alternative financial system to the legacy system of banks, exchanges, insurance companies, mortgage providers, etc., but reimagined from the ground up with no intermediaries in the middle. Unlike traditional finance, with no gatekeepers to turn down your application, DeFi lowers the barrier to entry, allowing more people to access financial services, take out a collateralized loan, or earn a yield on their assets. Help expand the capabilities of DeFi by building an app or module with the Cosmos SDK.

 

GALAXY PRIZE: CHALLENGE KAVA

Kava is a software protocol that uses multiple cryptocurrencies to allow its users to borrow and lend assets without the need for a traditional financial intermediary. Kava's HackAtom VI challenge asks you to build a fully autonomous options protocol as a Cosmos SDK module. You can assume that you have access to a price oracle.

 

REQUIREMENTS

All projects must be built using the Cosmos SDK, version 0.39+. Submissions should have at least minimum-viable functionality (ie, the main user actions are all supported by the protocol).

GALAXY PRIZE: CHALLENGE KI FOUNDATION

The Ki Foundation bridges CeFi and DeFi through an innovative range of products that provide users with an easy and seamless way to engage in DeFi operations, including its flagship Ki Chain blockchain and bridges to other blockchain ecosystems. The Token transfer capability of IBC was the first step showcasing the power of interoperability between Cosmos SDK-based chains. In order to grow the value of this thriving ecosystem, we need to implement the next step of cross-chain interoperability through the Interchain Account feature. 

For this challenge, developers will need to implement the module enabling cross-chain interoperability with features such as delegating, undelegating, sending coins, or operating an application-based action such as swapping on a chain like Osmosis.

The idea is to leverage IBC capabilities and be able to use application-specific features on different sovereign chains in the Cosmos ecosystem. Specifically, we would like to be able to call any custom Cosmos SDK message on any IBC-enabled chain from an interchain account. 

A concrete use case we want to implement is the possibility to interact with the Osmosis GAMM module. For instance, we would need to deposit liquidity in pools and swap tokens. Another important aspect is the first class support of Interchain Accounts on CosmWasm smart contracts. We would like to use InterChain Accounts features from a CosmWasm smart contract and be able to interact through IBC with a CosmWasm smart contract on another chain.

 

REQUIREMENTS

Here is how we see the global architecture of the project and how we imagine the delivery. Basically, the challenge will include the below major tasks:

 

  • Specifications:

  • IBC Relayers Implementation:

    • Analyze the ongoing initiatives from different parties regarding ICS-27 support in the different relayers implementations

    • Identify the missing features to fully support ICS-27

    • Submit a PR to at least one major relayer implementation (Hermes, Go relayer, or confio typescript relayer)

  • Cosmos SDK:

    • Identify if the Interchain Account feature could be designed as a Cosmos SDK module, easily integrable to any IBC-enabled Cosmos chain

    • Submit a PR to Cosmos SDK with the implementation of an Interchain Account module

  • CosmWasm / Wasmd:
    • Identify the ongoing initiatives from different parties regarding ICS-27 support in CosmWasm contracts
    • Identify the missing features to fully support ICS-27
    • Submit a PR to wasmd with the implementation of ICS-27 specification

  • MVP: Implement an MVP showcasing the different features

    • End to end test repository with a working demo

    • Documentation and guides on how to use the product

    • Interoperable product

    • Deployed on Juno testnet

STARSHIP PRIZE: CHALLENGE SECRET NETWORK

Secret Network is an open-source protocol that performs computations on encrypted data, brining privacy to smart contracts and public blockchains.  Secret's challenge is to build a game on Secret Network using CosmWasm, Secret NFTs, and on-chain randomness.

 

Blockchain NFT gaming is taking off, even though main components of gaming are non-existent with traditional blockchains, namely private data and randomness. To create Games of Incomplete Information, private data must be utilized, and to create fair games, randomness must be utilized. Randomness can also be utilized to generate unpredictable mazes, puzzles and maps, to roll dice, to shuffle cards and cubes, to create gaming AIs, and to add "chaos" in order to enhance in-game experiences.

 

Traditional blockchains like Ethereum don’t have data privacy or on-chain randomness, therefore gaming creators resort to centralized solutions. This makes for less fair and transparent games, and also leads to non-ideal UX at times (getting randomness from off-chain sources takes time).

 

On Secret Network, all contract’s data is private by default. Only the contract can read its own state, and only the transaction sender can read the transaction inputs and outputs. By utilizing private state, contracts can store a private entropy pool and from it derive private random numbers instantly and at will.


The participants to this challenge will need to build a game on Secret Network using CosmWasm, Secret NFTs and on-chain randomness.

 

REQUIREMENTS

Implementation of blockchain gaming app on Secret Network

Write contracts using CosmWasm

Utilize private data (Game of Incomplete Information)

Utilize on-chain randomness 

User interface in a mobile app or a web browser

Using Keplr is optional

May implement a simple local wallet for better UX

 

BETTER POINTS:

Use Secret NFTs (SNIP-721)

Use query permits

Don’t use viewing keys

EARTH PRIZE: EARTH

 

OVERVIEW: EARTH SUSTAINABILITY AND ECOLOGICAL REGENERATION ON COSMOS SDK

The ultimate purpose of the Internet of Blockchains is to empower people everywhere with digital technologies that enable communities to prosper. When communities prosper, they can regenerate the planet, and respond more effectively to the climate crisis. Change the state of the planet by building modules, accessible apps and integrations for local currencies, self-sovereign identity, non-fungible impact tokens, verification oracles, decentralised impact exchanges, and earth intelligence data. This is the Interchain Earth Mission!

 

EARTH PRIZE: CHALLENGE REGEN NETWORK

Regen Network is a platform for a thriving planet, that aligns economics with ecology to drive regenerative land management. Regen Network is soon approaching its first mainnet upgrade, which will include the launch of the first module for representing carbon credits (“ecocredits” on Regen Network) as on-chain assets on a Cosmos SDK-based blockchain.

 

Regen Network's challenge for HackAtom VI under the EARTH category is to bridge ecocredits into the interchain ecosystem—by implementing an IBC application that allows users to move these new types of ecological assets across different blockchains.

 

Ecocredits are more feature rich than other familiar standards such as ERC-20 tokens, and allow for additional ecologically pertinent metadata, as well as the ability for a holder to “retire” these credits—thus claiming the credit as an “offset” in carbon accounting terms. As such, your submission should take into account these nuances and provide for cross-chain access to metadata, as well as cross-chain capabilities for retiring credits.

 

REQUIREMENTS

The challenge submission should include:

A complete IBC application in its own repository

Documentation of the specification and functionality

A readme with instructions for use

A demo showcasing cross-chain ecocredit transfer & retirement using a fork of regen-ledger and a testnet of another IBC ecocredit enabled blockchain.

Bonus points will be provided for extending this functionality into a dApp where end-users can issue, transfer, and retire ecocredits in a cross-chain capable way.

EARTH PRIZE: CHALLENGE CO-SPONSORED BY GRANT.FISH AND JUNO

Juno is an interoperable smart contract network that is highly scalable, robust, secure, and easy to deploy. Grant.fish is a validator operated by stake.fish that has launched with the Cosmos Hub 3 upgrade. Both believe that the ultimate purpose of the Internet of Blockchains is to empower people everywhere with digital technologies that enable communities to prosper. When communities prosper, they can regenerate the planet and respond more effectively to the climate crisis. 

 

For this important challenge, Juno and grant.fish are teaming up to ask you to change the state of the planet by building modules, accessible apps, and integrations for local currencies, self-sovereign identity, non-fungible impact tokens, verification oracles, decentralized impact exchanges, and earth intelligence data. 

 

Create something that can leverage the power of the Juno platform and Cosmos IBC functionality that can support carbon emission reduction initiatives. Identifying ways to tie in existing Juno functionality with regenerative-focused networks like Regen Network could be a great opportunity as well.

EARTH PRIZE: CHALLENGE IXO FOUNDATION - The EARTH CRISIS CHALLENGE

Humanity is on the brink of a fundamental state-transition into planetary chaos. Erratic weather patterns and natural disasters resulting from flooding, droughts and wild-fires are becoming more frequent each year, as climate-change accelerates. Mass human migrations away from disaster zones are already beginning and we see conflicts and famine. Re-emerging tropical diseases and lethal new infectious agents, such as COVID-19, threaten human and animal life. Natural resources are being depleted at an alarming rate, way beyond the planetary boundaries for sustainability, and imperial wars to control and own these resources have already begun! 

 

What can we do to avoid mass extinctions of life-forms on Earth and to reverse the threat of losing centuries of human progress?

 

We must develop responses to the Earth Crisis using anti-fragile digital technologies and data about the state of the world that is verifiable and increases our intelligence. The ultimate sense-and-response system must become globally distributed and enable intelligent, rapid, effective local coordination, with incentives for people to take action, and to get sufficient resources to flow where these are most needed. 

 

The ixo-Cosmos Internet of Impact Hub and connected sovereign Impact Zone networks can provide the blockchain infrastructure needed to respond to the Earth Crisis. ixo describes the Internet of Impact as a global digital immune system for humanity.

 

Your challenge is to build and demonstrate applications using the Internet of Impact, or software components that add capabilities to The Impact Stack, for preventing and responding to specific types of real-world Earth Crisis events. 

 

You will collaborate with Problem-owners who have place-based or domain-specific knowledge and expertise about use cases that may range from making earth state observations for early-warning systems, to financing earth state-changes, to enable local citizen action, and to create global change. 

 

This is an enormous, urgent opportunity space of the highest priority, in which to apply your skills, connect and interoperate with existing systems, integrate the latest AI technologies, and build better alternative decentralized financing and data verification mechanisms.

 

REQUIREMENTS

Demonstrate a solution for a specific real-world use-case that is ideally built in collaboration with a problem-owner who understands an Earth Crisis events domain. For instance, The Red Cross International Disaster Bonds insurance mechanism for rapidly delivering relief financing to communities threatened by natural disasters. The Earth Crisis problem space is rich with opportunities, so we look forward to seeing really interesting use cases that address real needs.  

Build your solution on the Internet of Impact using the ixo-Blockchain SDK. The blockchain base layer can either use the current Go modules and capabilities implemented in the ixo Pandora-4 Testnet (which has the same configuration as the ImpactHub-3 main-net), or you can build and configure new chains that include base ixo-Blockchain modules, with additional modules imported from the Cosmos SDK, or other projects. You may even decide to build your own custom module/s, using the Cosmos SDK framework, or implement smart contracts–for instance, using the CosmWasm module.

Create entities with specific roles and capabilities in your solution, using ixo Decentralized Identifiers (DIDs) and combinations of the following entity types:

Agents that are Individuals or groups with Self-sovereign Digital Identity.

Projects for managing agents to finance, deliver, claim and verify pre-defined results. 

Investments for forming and distributing capital assets to invest into other entities, using sustainable DeFi mechanisms, such as ixo Alphabonds.

Oracles that provide trusted information from the real-world, or offer prediction services for proofing and verifying claims, personalising services, prescribing interventions, preventing risks, protecting against threats, and enabling more effective human participation in decision-making. 

Assets that are tokenized using Interchain Identifiers, to represent any digital asset types such as tokenized Carbon Credits or other classes of Impact Tokens, tokenized titles and rights over physical assets, tokenized data assets, etc.

Templates that encode the claims and data models for the Internet of Impact Linked-data Graph, which enable users to quickly configure new entities from template libraries.

Cells for coordinating groups of agents with a shared purpose, including through DAOs mechanisms.

Provide a compelling user interface to demonstrate from the target user’s perspective how the solution works to meet their needs. Using personas and user journey maps would be helpful in your presentation of the solution. You can build your interface using the ixo-Webclient (React, Typescript), with the option to add new features and systems integrations into the current version of the web-client. Alternatively, you can build entirely new client applications, using the ixo-Client SDK and javascript libraries. For instance, an IoT device client that feeds information into the  integrating IoT devices with the ixo system.

Consider building service integrations that extend the capabilities of the Internet of Impact to receive information and services from other Web3 or Web 2.0 networks, and/or to provide information and services into other networks.

EARTH PRIZE: CHALLENGE IXO FOUNDATION EARTH TOKENS

The Earth Tokens Challenge

For this challenge “Earth Tokens” are defined as classes of tokens that are created and used for the purpose of sustainable socio-economic development, climate action, and ecological regeneration.

Tokenization is transforming how people are incentivised, how decentralised economies and communities are secured and governed, how capital gets formed and allocated, how products and services are financed, and how digital or physical assets are used for financial or non-financial applications. 

Across this wide range of applications there are many different classes of tokens. 

Each token class has a unique set of token properties and token behaviours.

The Interchain Identifier (IID) Specification describes how to configure various classes of tokens, using token templates and standards that are designed to be interoperable across all blockchain networks, and addressable from the web.

 

Consider these 3 use-cases as examples of how different classes of Earth Tokens could be configured,:

Community Currency Tokens enable people to exchange their time, goods and services to grow a local economy. A token issuer may define a class of fungible, fixed-supply tokens that can only be transacted between identified accounts with verifiable credentials.

Mutual credit Tokens enable small businesses to transact with less reliance on external capital and this token class may have more characteristics of non-fungible tokens, when they are linked to verifiable claims about the provenance of goods produced–for instance, in sustainable supply-chains, or if these tokens accord the holder an automated right to be paid for invoices when orders are delivered.

Renewable Energy Tokens enable independent power producers to sell certified green electricity, or to claim Carbon Credits that can be sold as offsets. Non-fungible Renewable Energy Certificate (REC) tokens may include the right for a token-holder to mint fungible fractional units of the REC tokens, to trade for electricity supply.

 

These examples only begin to demonstrate the incredible potential for configuring classes of tokens for different Earth Token use-cases. For this challenge you will build and demonstrate innovative ways for Earth Tokens to be issued, traded and used in Sustainable DeFi and Regenerative Finance (ReFi) applications. 

 

Suggested areas for innovation include (but are not limited to):

 

Great UX for creating and using Token Templates to mint and different classes of Earth Tokens.

Decentralised marketplace mechanisms for trading different classes of Earth Tokens. This may include new types of services that enable tokens of different classes to be bought or sold, auctioned, used as collateral, lent or borrowed, used as offsets, etc. 

Automated market-makers for trading heterogeneous token classes, such as a liquidity mechanism for pooling fungible with non-fungible token classes.

Authorisation Capabilities (zCaps) to provide secure delegated authorisation mechanisms for interacting with token services.

Clever ways of using Liquid Staking or other token derivatives, to unlock capital for sustainable development and ecological regeneration.

Software tooling or integrations that further enable Earth Tokens use-cases.

 

REQUIREMENTS

Address a real-world need that is relevant to the Interchain Earth Mission, based on a real or fictitious use-case that has a great user story.

Implement the Interchain Identifiers (IID) specification and Token Templates.

Use the standard Cosmos SDK modules, and/or add new features to existing Cosmos modules, and/or create new module/s.

(Optionally) build on the ixo-Webclient, with the possibility of adding new features and/or integrations. 

(Optionally) contribute new software tooling for implementers of Earth Tokens applications.
