$18,000 EDGE196 Challenge (3)

The participants has to use USDAO stablecoin, participants will be provided with USDAO SDK which can be used to create innovative solutions in the space of the following:

i)Decentralized Lending : Borrowing and lending made easy and accessible for all Have you ever tried to borrow money from a bank? Let’s face it: The current lending industry is inefficient. Especially with lots of documents to fill up, and high-interest rate. P2P lending is rapidly growing in personal finance. Now, both borrowers and lenders are connected all over the world via blockchain. All without giving the bank their cut. As lenders, you can remain completely anonymous and does not need to register anywhere. Just select your preferred loan from the marketplace. Next, initiate from your wallets. Borrowers can return the loan in a low- interest environment.

ii)Trade finance – Supply chain : Margins are already slim in container shipping. Yet, the processing of paperwork is more costly than the shipping container. Improve transparency between vendors ,Quicker documentation verification and Credit/Bill settlement per participants.

iii) Entertainment Industry : Fair Royalty distribution to artist and improved copyright protection.

iv) Tourism: Companies provide traditional paper, plastic tokens, coupons, discount and other sorts of inefficient reward and loyalty rewards to their customers. Lets change that with Blockchain/DLT technology incorporating USDAO.

v) Digital Ads revenue: Are you tired of paying high online advertising costs? Or how about fearful of being banned from your online content? Create ads marketplace where buyers and sellers buy advertising at very low fees. Users can generate revenue through reviewing websites and share data, you can get paid too.

vi) Finance – Payments, Insurance and Investment As crypto currencies are becoming a daily part of life its needed to be simplified for the mass population. so, people can get benefitted from.

vii)Freelancer work portal: Better jobs. Better talent. Remote As the world move towards web 3.0 . The trends have move towards remote jobs, Create a work portal with a payment escrow mechanism which benefits both the company and the job seeker.

The participants can choose any one of the above segment to create a solution with USDAO stablecoin. The application must resolve a current problem tackled through the USDAO and blockchain/DLT technology

$8,000 Cardano Challenge #1 - Marlowe contracts (3)

The challenge is to find existing financial agreements that could be modeled as Marlowe contracts and develop them inside the Marlowe Playground. Given the static restrictions that
Marlowe has, some agreements could require a companion Plutus contract to be realistic, but for this challenge we prefer to limit the scope of the contracts.

Some examples of financial agreements that could be modeled include:

● A year-long gym subscription with monthly payments.

● A car/apartment lease for a fixed amount of time with a tenant, an owner and a

● A product purchase where the VAT is paid automatically to a government tax account.

● Any other transaction where tax can be collected automatically.

● A crowdfunding contract where multiple participants try to reach a goal, if they do, the money goes to the participant that created the fund, if they don’t, it goes back to the

● A derivatives contract, i.e. a contract that references native tokens or other contracts, resp. NFTs. That could be vanilla or exotic options, futures or other derivatives.

● A secondary market contract where parties can trade their Marlowe contracts.

We value innovation: use these ideas for inspiration, but don’t restrict yourself to just these. The blockchain is the limit.

If you can manually add the new contract to the Marlowe Run prototype to see how final users could interact with it (hint: look for web-common-marlowe/src/Marlowe/Market.purs in the plutus repository), you will get extra credit.


Award of prizes is at the judges’ discretion, but their choices will reflect innovation, ingenuity and
achievement in the submissions.

1st prize $5,000, Runner up $2,000, 3rd $1,000.

#1 Pass Through Billing
#2 Pizza Delivery
#3 Turing Toil

$2,000 Cardano Challenge #2 - Marlowe Future (2)

If you don’t feel confident to write Marlowe contracts, you can instead envision how you might
make modifications to the various components of the Marlowe Suite, or describe how you would
build on these components to provide a business service of some kind.

2 winners of $1,000

$5,000 Avalanche Subnet And Virtual Machine

Avalanche subnets allow anyone anywhere to spin up a taylor-made network w/ custom virtual machines and complex validator rulesets. They enable permissionless and permissioned networks to launch with optional privacy and regulatory compliance.

Virtual machines are the application-level logic of your blockchain. Technically they're state machines that include the state of your blockchain, the state transition function and an API that users can interact w/ your blockchain. Avalanche provides APIs for creating DAG blockchains with partial ordering for P2P payments and linear blockchain with total ordering for smart contracts. Developers get thousands of tx per second with sub-second immutable and irreversible finality out of the box and don't need to worry about the underlying networking, consensus or data structures, all of which are handled by the Avalanche network.

Tools or Stack Required

AvalancheGo, AvalancheJS

Judging Criteria

This category is limited to 1 winner. The submission which most closely meets the requirements will be the winner. Partial or unfinished submissions are not eligible for the prize. If no submission meets the requirements then there will be no winner.

$3,000 EnDAOment Challenge (2)

We have become accustomed to “Everything-as-a-Service.” Whether or not you use a platform like Netflix, you’ll be charged the same fee every month. But what if users received some of their money back — that they could reinvest into the platform?

We challenge participants to build a DAO on an Ethereum testnet that returns a pro rata amount of funds to a platform’s users – after they contribute a monthly SaaS payment – based on their monthly use of that platform’s services. The user could then redeploy those funds as desired, either kept as a refund or invested into the platform itself to vote on the direction of its content.

Solidity, Typescript or Go, TheGraph, any static website hosting service (Netlify, Github Pages, Vercel, etc.)

Prizes will be awarded to the most complete and thorough example of functionality, assessed through a visual presentation and a code review. Deployment to the Ethereum mainnet is not a requirement.

Anthony Apollo, Frank Apollo, and Alex Sheehan

One-time cash payment, in United States Dollars.

First Place: US$2,000. Second Place: US$1,000.

Kyodai Technologies, Inc. will be able to promote the teams and their respective entries through the social media accounts for its platform, Rensa Games.

$1,250 Best Technical Demo - Danno Ferrin Challenge

$500 From Danno Ferrin / $500 match from UW Blockchain Center / $250 Upgrade from TheCryptoShow.com

Present the best demonstration of working or hacked code/systems developed at the hackathon. Slideware is great for context and vision, but this challenge will reward the best technical demonstration.

The technical demo will need to be integrated as part of the main presentation. It can be short. Entrants will be ranked first by whether an actual technical demonstration occurred, then by the awesomeness of that demonstration.

Winner will need to submit an Ethereum main net payment address after the announcement of the award. The winning prize will be sent to one address and the team will be responsible for any distribution from there.

Danno Ferrin

This $500 is coming from my personal funds. In 2019 I felt there was too much slideware and not enough sizzle. My solution is to incentivize the demo.

WyoHackathon loves this personal Challenge and matches it with an additional $500!

#1 NFT^2 NFT Derivative Platform

$7,500 DigiByte Challenge - Update DigiByte's Rosetta Implementation

When Coinbase announced the release of their Rosetta blockchain middleware specification, the DigiByte Core Developers completed the implementation against version 1.4.1 of the Rosetta Specification. However, since the completion of 1.4.1, Coinbase has released many subsequent updates.

For this challenge, update DigiByte's Rosetta Implementation to the current stable version of 1.4.10. DigiByte's Rosetta implementation will be used to build the foundation of future DigiByte developer tools. Please reference the following resources for the challenge:

1) Familiarize yourself with the Coinbase Rosetta Data and Construction Specification here: https://www.rosetta-api.org/docs/welcome.html

2) Review the DigiByte Rosetta SDK 1.4.1 Pull Request as a point of departure here: https://github.com/DigiByte-Core/digibyte-rosetta-nodeapi/pull/2

3) Integrate the challenge solution into the DigiByte Rosetta SDK Docker Container here: https://github.com/DigiByte-Core/digibyte-rosetta-docker

4) Validate that the specification implementation is valid by using the DigiByte Rosetta SDK CLI here: https://github.com/DigiByte-Core/rosetta-cli/tree/master
