Please describe your proposed solution

The project will solve the closed source and opaque business model from bet promotors.

• All betting contracts are open source.
• Contracts Audited by third party.
• Bet with Ada get Ada back.
• All Ada used in a bet is distributed to winners (minor minimum lovelaces due to rounding values)
• Values on each bet can be traced in Cardano Blockchain, Contract Addresses.
• Odds are not manipulated; they reflect gamers bets. Verifiable on chain.
• Security of being Cardano Smart Contract.

Currently we have a dozen countries and championships (soccer) in our system but as time and demand grows, we will add more.

How does it work:

A player chooses the result (Home, Away, Tie) for a game.

As he submits his bet, he will receive X bet ticket tokens with the game policy Id with the "name" corresponding to the chosen result, and the X Ada he bet is deposited on the games pot contract.

The Minting and Pot Contracts verify:

• bet ticket is correctly calculated with Ada that is sent.
• the game has not started yet.
• correct amount of ada is sent to the Game Bet Pot Contract Address.

The Odds for the game are recalculated for the dApp.

Gamers can check veracity using any cardano explorer using the policyId and Pot Address for each game.

Every day the platform gets the results of each game from a thrusted Public API.

The result of the game is then stored on the Game Pot Contract.

The UTXO contains the result and the Odd Multiplier for winning bets and is signed by an Oracle Address.

The gamer goes to his winning bets and send the ticket token to the Pot Smart Contract. This verifies that the Ticket Token is:

• the game as occurred
• the game as a UTXO signed by oracle with the result
• the Bet Tickets are from the correct game and winning result.
• with the result UTXO verifies the value to redeem
• aproves the transaction from Pot to Wallet that sent the Bet Tickets.

Each game has its own pot address where all bets are deposited. Each game as a unique policyId that identified.

Most of this can already been seen in <https://preview.betttingada.com>.

This dApp is under development so features might be different from day to day. We hope to have you feedback so we can incorporate it!

Please define the positive impact your project will have on the wider Cardano community

The first impact is the building of a new business that is transparent, breaks "the mold" of opacity from big installed corporations.

More value from ones bet.

The availability of the project in open source allows the community to help it grow, fix shortcoming's, teach how powerful cardano utxo and validators can be.

Looking at our roadmap a lot more is planned.

What is your capability to deliver your project with high levels of trust and accountability? How do you intend to validate if your approach is feasible?

As anyone can see the project is already very advanced.

Already has the smart contracts very solid, but still need some edge cases tunning and audit.

What are the key milestones you need to achieve in order to complete your project successfully?

Milestone 1: The first milestone is to deliver the full experience on preview network.

Betting, Redeeming bets.

1 month

Milestone 2: Audit and Open-Source Plutus contracts

1 Month

Final Milestone: Add more features to the dApp.

• Better filters to find games
• Better own bets navigation from user.
• Add favorite teams, championships.

Open source dApp

2 month

Please provide a cost breakdown of the proposed work and resources

• 10.000 ADA for Design a final logo
• 10.000 For Games/Venues, Result API (estimation)
• 50.000 For Developer fees
• 10.000 For blockfrost (estimation)
• 10.000 for hosting solutions.(estimation)
• 10.000 for marketing and branding

This is at today's ~0,5USD per ADA.

Some of these costs will be covering the next step that is going for mainnet.

The results API that powers the Oracle is centralized. In the future we can shift it to a decentralized oracle.

How does the cost of the project represent value for money for the Cardano ecosystem?

The value created for Cardano Blockchain is:

1. New business case that is both open source and transparent in a clouded business area that are sports bets
2. Demonstration that Cardano technology can power ANY use case with the correct approach.
3. Open source the contracts paves the way to more use cases build on Cardano … all kind of Bets.
