This repository is intended for developers who want to work on existing "bounties", or community members who want to fund their own IoTeX projects and are looking for developers.

Halo Bounties

Halo bounties are a "wishlist" of new features, bug fixes, or standalone projects proposed by the community or by the IoTeX Foundation. Bounties have a well defined scope of work, verifiable deliverables, and a funding limit. Anyone can start a bounty to fund their favorite idea and help the growth of the IoTeX ecosystem, and anyone can work on existing bounties and claim the reward once work is done.

Work on a bounty

If you are a developer, or an ecosystem builder, choose from the current list of bounties any project you feel confident to complete: pay special attention to the bounty description, the expected deliverables, and get in contact with the Bounty funder for clarifications by either commenting under the Bounty, or reaching out to the funder contacts.

Please notice: Bounties can have different formats, make sure to clarify with the funder if multiple people are allowed to work on the same bounty, what are the rules to select who gets paid. If you feel like you are the right person for a specific bounty, you may try asking to get it reserved for you.

Fund a bounty

If there is a new feature, a bug fix, or a project that you would to get implemented on IoTeX, you can fund your own bounty by adding it to this repository issues:

Please notice: if you create a bounty you are responsible for paying out the reward when work is submitted that fulfill all the requirements.

Power your dApp with Verifiable Real-world Data

Power your dApp with Verifiable Real-world Data

Welcome!

Thank you for your interest in IoTeX. You are welcome to participate in our competitions. Also, take a look at the other prizes:

• Power your dApp with Verifiable Real-world Data (this prize)
• An Analytics Dashboard for our ioTube Bridge
• Port your favorite dApp to IoTeX using Web3

Please join our Discord to discuss the bounties.

Bounty Prize

2500 USDT
to the most creative submission

The Challenge

Pebble Tracker is a multi-sensor IoT board that converts real-world phenomena into verifiable, blockchain-ready data. We would like you to create a simple dApp that gets periodically fed by these verifiable data messages containing sensor values, verifies the message signature, and takes specific actions based on the sensor's values.

Below we provide the basic specifications, but anyone is free to extend it and get creative:

1. Use our Pebble Simulator to generate a set of Pebble sensor data points along with their signature.
2. Create a smart contract that stores a list of "registered" devices. The contract owner can allow or block/delete devices. Anyone can "register" a new device (use the device IMEI and Public key for identification).
3. The contract should have a method to receive a Pebble data message and verify both data source device and data integrity.
4. The contract will reject data messages that come from non-whitelisted devices or whose signature is invalid.
5. For valid data messages, The contract will take some action based on the sensor values it received (e.g., store the latest values, transfer funds if a specific event is detected, etc...)
6. Create a frontend for the smart contract that allows users to log in with Metamask; allows any user to register a device, and the contract owner to allowlist, block, or delete registered devices, and displays any data relevant to the smart contract (e.g., display all devices, display latest data per device, display token transfers, contract balance, etc...)

For the Smart Contract, you are required to use Solidity 0.5.13, for the frontend we suggest our dApp sample (though not a strict requirement)

Acceptance Criteria

• Code must be clear and well documented
• Applicants work must be open-source on GitHub
• Although simple, the frontend should be clean and pleasant
• You will are allowed to be creative and build your own IoT data service, as long as all the functions described above are included
• The dApp repository must include a detailed installation & usage guide
• Additional grant via Halo Program if strongly exceeds expectation

Judging Criteria

• We will require a demo of the submission
• We will assign the prize to the dApp that uses the IoT data in the most creative way

Pebble Message Verification

Important notice: the simulator only support Linux and macOS

Data message verification is the key concept behind the verifiability of Pebble Tracker data: you can both verify the source (i.e. the device public key) of the data, and the integrity of the data in one single step using the signature included in the Pebble Tracker data messages:

...
"signature": {
  "r":"4c05a4fa3eba782780a517ba03ef6fdd65e5b560a027808b47fcc6ed2b864169",
  "s":"05bde29104febe10c096c550b91f5d8ed2cf0d15fe48e164ee0e9765dda76f34"
}

rand s are the two components of the elliptic curve signature (using secp256k1 curve) of the data message, obtained by signing the keccak256 hash of the JSON object rendered to a string without any formatting. A possible example to verify the message signature would be the following, using the solidity ecrecover function:

// The verification function is called with all Pebble IoT data values, including the signature `r` and `s` components
function receiveData(string temperature, string latitude, string longitude, ..., bytes32 r,  bytes32 s)

// buildJsonString should just rebuild the original pebble data message into an unformatted
// json string using the data passed to receiveData(), and returns the string cast to bytes  
bytes32 hash = keccak256(buildJsonString(temperature, latitude, longitude, ...));
 
// Recover device address from the data message signature 
bool hit;      
address deviceAddress;
// the signature version "v" can be either 27 or 28, the device does not provide it so
// we test both of them       
for (uint8 v = 27; v < 29; v++) {        
  deviceAddress = ecrecover(hash, v, r, s);        
  if (whitelist[deviceAddress] == 1) { 
    hit = true;          
    break;        
  }     
}

If ecrecover() returns a valid, non-zero address, this means that the data integrity is assured (i.e. the data passed to the contract correspond to those originally signed by the device). If the returned address is also included among the whitelisted devices then both the source and integrity of the data are verified, all is good and the contract can go ahead processing the sensors data (which is now trusted data!) and taking the specific actions required by the dApp.

proposal: use Github Pages as a simple dashboard to track all halo projects

Note I create this as an issue instead of a pull request because Github does not allow me to create pull request for this rare case

This proposal is to address the RFP idea Dashboard to Track Halo projects.

The solution is to use Github Page to show all the proposals and their milestones.

Demo: https://ykou.github.io/halogrants/

Tradeoffs:

• The whole website is backed by a markdown file https://github.com/ykou/halogrants/blob/gh-pages/index.md which means it has very low maintenance cost and everyone can update it easily without setting up development environment. We don't need a frontend engineer to maintain the site.
• It is possible that the page becomes long as the number of projects grows, but I don't think that is going to happen any time soon.
• Github provides several beautiful themes that work automatically on the site. Switching themes can be done in a few clicks. We don't need designer resources for the site.
• no $ cost on server/CDN/pipeline.
• The downside is it is not flexible enough to do the management work. We'll need to go through the pull request review process to update the proposals and milestones.
• Currently it does not handle project traction, e.g., DAU, daily active txs and so on. But we could do it by asking the individual projects to expose some live status icon urls so that we can include the icons in the markdown, similar to how other github repos include pipeline status icons in the README files.

Port UMA Protocol On IoTeX

Bounty Description

Port and deploy UMA protocol (Universal Market Access) on IoTeX to allow any dApp on IoTeX to use UMA to build synthetic financial products.

Context

As IoTeX is fully compatible with Web3 and EVM (up to solidity 0.5.17), both the contract part and the frontend part for any Ethereum dApp can be easily ported to IoTeX. Specifically, UMA is a product that allows to the creation of priceless financial contract templates that can be used to create synthetic tokens, Decentralized Oracle Service used to manage and enforce contracts on UMAm which would be very useful on IoTeX especially in combination with out real-world data oracle protocol.

Acceptance criteria

Set clear and verifiable acceptance criteria for the project. If required, split into milestones and split the following Reward section accordingly:

Milestone 1

• Deploy UMA on IoTeX (IoTeX developers should be able to deploy any financial product made available by UMA)

Reward

• Milestone I: $2500 in IOTX tokens.

P2P Prober for IoTeX Mainnet

Description

Build a system of probers to listen to P2P traffics on the IoTeX mainnet, collecting and aggregating P2P traffics, sample-storing some of them and visualizing the metrics on a dashboard.

Context

IoTeX mainnet is growing - it is now composed of over 100 delegate nodes talking to each other in a P2P fashion, to process transactions, produce blocks by reaching consensus and help others to sync. When debugging an issue on the IoTeX mainnet recently, the developers complain about the lack of visibility of the network at the p2p layer, e.g, which types of messages are congesting the network, from which nodes and why. Such a system would greatly help the developer to understand the current status of the network, implement new features that keep the protocol improving and scaling up.

Misc/References

This project should be composed of 4 parts:

• An P2P prober written in Golang; multiple instances of which will be deployed and connects to IoTeX mainnet's P2P layer
• A backend written in Golang that aggregates all collected information from probers
• A dashboard (e.g., ELK) that visualizes the network status and let the developers dive into some of the P2P messages that happened on the network
• The script (e.g., helm, dockercompose) to easily deploy the whole system to AWS or GCP, e.g. 10 probers + 1 backend + 1 dashboard

Acceptance criteria

• Milestone 1

• Architectural Design
• PoC (one prober + one backend + one dashboard with basic flows implemented)

• Milestone 2

• Full-features implementation with production quality
• Read to deploy to testnet and mainnet

🔥 Build a Dapp based on verifiable real-world data (NFT/Loot)

[THIS BOUNTY IS CLOSED]

Bounty Description

This bounty is part of a set of three bounties for the Gitcoin GR11.

Each one of the three bounties requires building a Dapp that makes use of the novel IoTeX architecture called TruStream, but with different levels of complexities.

If you apply for this bounty, you can build a custom Dapp that makes use of the Pebble Tracker IoT data fetched from the TruStream network. Additionally, you are supposed to integrate the NFT concept.

Prizes

• Winning up to 7000 USDT (IOTX equivalent)
• Based on the complexity and creativity of the project
• 1 Winner

Context

TruStream is a decentralized protocol developed on top of the IoTeX public blockchain. Its mission is to seamlessly connect devices and machines to the blockchain, contribute their data and utilities to Dapps autonomously, and power unprecedented innovations.

TruStream can be used to implement DAOs ("Decentralized Autonomous Organizations") of a group of devices or machines for a specific application.

Example applications

🔥 Build a "Loot-type" Dapp (preferred)

• Mint NFTs whose features are randomly created out of the device data (or the data a hash), and mint a "loot-style bag"

Generative NFT based on device data

• Generate an NFT where the features are represented by actual device readings (e.g. generate art based on latitude/longitude, temperature, ambient light, etc...)

• Mint an NFT based on device location (e.g. close to European capitals, World Heritage places), allow for more "valuable" NFTs to be generated by combining existing ones (e.g. "All European Capitals NFT" generated by combining the NFTs of each single city)

• Mint an NFT when the device has traveled along a route, combine multiple NFTs to obtain more valuable NFTs (e.g. "over 100km bike riding in 1 week", and generate the NFT card where the graphic is the actual route on the map

Acceptance criteria/rules

-🔒 Make use of the Pebble Tracker IoT data from the TruStream Network
-🔒 Integrate the NFT concept
-🔒 The project must be a fully working Dapp (i.e. smart-contract + Frontend)
-🔒The project must be uploaded to a web server incl. domain name
-⭐️ Extra points to projects that show care in the web design of the frontend
-⭐️ Implement the Dashboard + IFTTT concept (optional)

Antenna SDK for Arduino boards

Description

This port will provide transaction signing and broadcasting for IOTX token (transfers, balance, etc...), XRC20 tokens (transfers, balance, etc...), and smart contracts interaction, as well as utility functions like account creation, token units conversion etc... It will interact with a JSON-RPC API server (like our Babel service that implements Ethereum JSON-RPC API, or any other API server. communication with IoTeX Full-Node to broadcast transactions.

The library will suport popular Arduino boards, including ESP32, ESP8266 and Arduino Nano 33 IoT

Context

Arduino is a great platform for people & makers to experiment, learn and build IoT applications.
Joining Arduino & IoTeX would take these IoT projects to the next level, allowing users to effectively integrate an IoT-friendly Blockchain into their devices and applications. While IoTeX already provides some C++ examples (antenna-embedded), a comprehensive antenna-arduino library that implements IoTeX Antenna SDKs and is easily imported into Arduino projects is missing.

Acceptance criteria

The final deliverable will be made up by an Arduino library with PlatformIO compatibility. The library will follow the Arduino code standards. Along with the library, a set of examples and documentation will be created for the supported Arduino boards.

Below the Milestones with respective acceptance criteria:

Milestone 1: JSON-RPC over HTTPS

• JSON-RPC parser/serializer
  This is a Class including utilities to construct and parse JSON-RPC requests and responses. This will leverage a third party lightweight JSON library such as JSMN or cJSON
• IConnection
  This is an Interface for a HTTP/HTTPs connection. Possibly a mock implementation or an implementation for one board (eg. ESP32)
• Api
  This is a class/interface for the IoTeX JSON-RPC api. Will implement the following methods, which construct the payload using the JSON-RPC parser, send a request over HTTP using IConnection, parse the response and return it in an adequate struct/class. Implements the following methods (initially)
  • getAccount()
  • getNonce()
  • getTransactionByHash()

Milestone 2: Signature

• Transfer
  This is a class that represents a transfer. Holds the following data, as well as possibly some utility methods: amount, recipient, payload, gasPrice, gasLimit

• Wallet: a class that represents a wallet. Provides the following methods:

  • getPrivateKey(): creates a new wallet and returns the private key
  • getIoTeXAddress(): returns the native IoTeX address
  • getEthereumAddress(): returns the address in the Ethereum format
  • signMessage(): hashes a message using the private key and returns the hash
  • signTokenTransferAction() this will construct the token transfer message then call the signMessage and return the signature.

• Api: the following methods will be added to the Api class

  • sendTokenTransfer(Wallet, Transfer): Signs and broadcast a IOTX transfer

Milestone 3 - Contract execution

• Execution: class that represents a smart contract. Holds the following data and methods

  • contractAddress
  • amount
  • Methods to generate contract data:
    • setupContractData()
    • getData()

• Wallet: add the following methods

  • signContractExecution(amount,execution)

• Api: add the following methods

  • sendContractExecution(wallet, execution)

Milestone 4 - Test boards, Examples & publish

• Implement the existing interfaces for each of the supported boards:

• ESP32
• ESP8266
• Arduino Nano 33 IoT
• Cellular board - Possibly, depending on time

• Create a set of examples and documentation
• Publish the library

Time estimation

No specific deadline, but we'd like to have it ready by July 15th, 2021

Misc/References

Signature of actions

The message must be “constructed” in protobuf format (version is 1, nonce can be obtained from milestone 1, action will be of type Transfer for token transfers, Execution for contract calls and fields are passed as arguments to the call). https://github.com/iotexproject/iotex-proto/blob/28696168bf02b64a9fbf71edda0a68a4ad714c08/proto/types/action.proto#L205

Refer to the existing antenna-embedded signing module. If any fix is required to the signature function the IoTeX team will provide help on this

Protobuf

Protobuf encoding is needed for sending actions to the server. This will be handled by integrating a lightweight third party library such as NanoPb

Reward

3500 USD

• Milestone 1: 750 USD
• Milestone 2: 750 USD
• Milestone 3: 750 USD
• Milestone 4: 1250 USD
