In our previous post shared our mission at ETHDenver to drive interest in Ethereum smart contract applications that are run over the air with radio transactions and sensors to further connect blockchains to the physical world with FOAM Lite.
Today we are happy to share our bounty prizes for hackers developing on FOAM Lite and share updated developer guides and resources.
On the FOAM Developer portal you can find an overview of FOAM Lite, design considerations, real world examples, the cryptographic signature process and considerations for future work. There are also links to our github repositories and resources for installation steps. We hope it serves as a useful reference to show you how the concepts demonstrated here come together to enable an Ethereum-of-Things application.
We will be running a FOAM Lite relay node at ETHDenver and will be providing hackers a limited number of sensors that are 'Web3 ready transmitter' platforms for development.
Get onboarded with the FOAM Lite platform and learn how to bring your ideas to life! We will be hosting a FOAM Lite Developer workshop February 16th, 9-11am, at Mirus Loft (2nd Floor) *1144 Broadway, Denver, CO 80203, USA *part of BuidlWeek. This is an opportunity to get your hands on hardware and go in depth with our lead developer, Ilya Ostrovskiy.
BOUNTIES $15000
$7500 IN-PERSON // $7500 VIRTUAL
1. FOAM LITE DEMO APPLICATION
Description
FOAM Lite is designed to connect physical sensors to the Ethereum blockchain with radio transactions. For this bounty we ask hackers to explore applications that can take advantage of authenticated sensor data and consider impact and public goods tracks.
This consists of a smart contract evens that can be triggered by a radio transaction. For example, hackers can think about ideas ranging from environmental or air quality sensors that can open new forms of data markets to a people counter sensors that effects the attributes of an NFT on chain or unlock a drop when a certain number of people show up at a location.
An end to end application with a front end, on chain event and integration with additional protocols will win this bounty to show a FOAM Lite Demo Application in use.
Prize Amount
$1,500 IRL

2. FOAM LITE TECHNICAL INFRASTRUCTURE
Description
FOAM Lite is currently in early stages of development and need a number of improvements to be a full fledged protocol. We ask hackers to explore the depths of the protocol and investigate developments in areas related to how sensors pay gas fees and how fee markets could operate.
The main area we would like to see explored is a smart contract mechanism which allows for delegating the relay fee for a sensor to another address on chain that can sponsor transaction fees on behalf of an end node.
You can also expand the supplied tools to do all sorts of interesting relayer behaviors, such as maintaining a fee market for transactions you choose to relay, or creating special types of messages to display in the UI.
Prize Amount

3. FOAM LITE FIRMWARE IMPROVEMENTS
Description
At scale, a single FOAM Lite node would be receiving transactions from a number of sensors, which can be thought of as a fleet. Fleet management tools for sensor operators to provision their devices will expand the utility of FOAM Lite tools.
The firmware we provide is designed to get developers experimenting with FOAM Lite transactions over radio rapidy. However, it is very much a developer tool and lacks certain features that would be useful for more production grade applications.
Functionality such as persisting the private key and tracking the last nonce used as radio messages are sent is essential for enabling real world applications. The sensor board provided at the hackathon has a flash chip that can do this on board, but it is not currently utilized. Porting the firmware and writing a library to additional hardware platforms is also an acceptable avenue to explore for this bounty.
