Decentralized Arcade Machine (DAM) Grant Proposal

DAM x PUSH Grant Proposal

Project Name: Decentralized Arcade Machine (DAM)


About You:
Roshaan Khan:
I am the founder of DAM and have been in the blockchain space professionally for about 4 years, but have been involved as an investor and supporter for about 6 years. My background is as a Technical Product Manager in web3 for major L1s, but also moonlit as a consultant helping startups however I can. After spending my first couple of years in the industry helping nonprofits, funds, and incubators through education and documentation. During this phase, I wrote the original whitepaper for the Government Blockchain Association (GBA). Shortly after I joined Block.One, the creators of the EOS blockchain and EOSIO VM, as a TPM. Here I published my first piece of research in the blockchain industry detailing privacy in public blockchain technologies from an enterprise perspective. You can find that here.

Near the end of my stint at Block.One I began consulting a few projects specifically on economic and tokenomic system design as well as overall web3 product strategy. Then I joined NEM, a chain from 2014 derived from Bitcoin and one of the grandfathers of the blockchain space. They started a new chain named Symbol for which I architected and led the development of Garush, a fully onchain NFT system for encoding NFTs onchain and creating a censorship-resistant marketplace for these onchain assets. I enjoyed my role at NEM, but they were undergoing some organizational changes that would’ve changed my role, so we amiably split paths at the start of 2022.

During the last few years, I have been tinkering with close friends on various products in the space. From DeFi to NFTs to Infrastructure and Dev Tooling. While doing so we built on almost every major L1/L2 in the industry and learned of the shortcomings. Having a full career product managing the advancement of L1s we saw glaring issues in the options available to developers and began work on what is now known as Umbrella Labs. We are building various pieces of technology that focus on easing the end-user and developer experiences within web3.

Finally, we went to Eth-SF on November 4th and met the PUSH team. We pitched our vision for DAM and what we were trying to build. As hardcore gamers ourselves we felt there was a glaring disconnect between how web3 games are built and how gamers actually game. We were met with great support from their team, and they recommended we apply for grants to push our hackathon project to the next level. Now here we are with this proposal!

Project TL:DR
DAM lets devs focus on making good games by offering an “on-switch” for game devs to activate web3 features. DAM uses web3 to power Collectibles, a Metaverse Marketplace, and eSports as a Service through a novel Proof of Victory mechanism.

Proposal Category
Primary Category: Gaming
Secondary Categories: NFT, DAO, Tooling

Project Overview
Building Good Games Is Hard. The average AAA game takes about four years to develop, with a minimum cost of over $80 million. It’s just as hard to build a successful web3 application. In 2021, VCs invested ~$30 billion across 1,278 web3 deals. Making the average raise $23.5M with expectations of needing more.

DAM lets devs focus on making good games.

Connect your game’s APIs to DAM to enable:

  1. “win2earn” contracts that act as PVP lobbies for users. Put your money where your mouth is and test your skills against other players with your proof of victory stamped on-chain for a global leaderboard and bonus prizes.
  2. Integration into DAM’s homepage - a metaverse game marketplace (think Steam) where you can tap a community of gamers.
  3. Enable onchain collectibles and currencies for your games through the DAM Marketplace.

The architecture diagrams are complete, and we know exactly what to build and have clarity on how to build most of it. The biggest lift will be the web2 aspect of creating an API system for games to connect to and relay in-game information to spin up PVP contracts and decide on winners. The Marketplace and NFT features are things our team has done before, so we’re confident that they will not be too difficult.

During the hackathon, we integrated PUSH as a chat mechanism and are using the Skale blockchain to offer gasless environments for both players and game developers. We also have a full business model (fee on PVP Contracts and marketplace) and a utility token ($DAM) that’s used to secure the Decentralized Arcade Machine.

We believe that with a $500k budget (and devs onboarded from day 1) we could get to a fully functioning product within 6 months. We have support from the internal Skale team, so the help of their solution engineers and community is a key factor in our ability to deliver quickly.

Value Proposition to Push Protocol
PUSH is used in two major ways within the DAM ecosystem. For the Eth-SF hackathon, we implemented the wallet-to-wallet chat functionality that’s visible in our Github. We want to use PUSH to create chat lobbies between players before, after, and during matches. Furthermore, this chat function allows developers not to have to worry about creating social functions within their application and can let us handle it through PUSH.

Additionally, we want to utilize PUSH to deliver notifications to users when Collectibles are sold/bought, when games are won/lost, when games begin/end, and when users receive a challenge from another player. Creating a robust notification system is key to a seamless gaming experience, and we believe PUSH is the best way to accomplish this.

Lastly, there are a plethora of game developers utilizing PUSH in their stack. We believe we can help these games reach a larger audience and have more robust features. Consequently supporting the PUSH ecosystem of developers with an easy-to-use tool.

Funding Requested
148,148 PUSH @ $0.27 ($40k USD)


Phase 1: 3 Months

  1. Create PVP smart contract logic
    Smart contract system that handles multiple players’ inbound payments and then sends a win2earn prize to the winning address based on an off-chain signal.
    Logic Includes:
  • Setting up a PVP lobby in-game creates contract on-chain.
  • Variable “Lobby SIze” which is the number of players allowed in the match.
  • Variable “Buy In” which is the amount players must input to contract to play.
  • Contract reads game state to determine who was the winner.
  • Contract pays out the winner of the match after deducting the platform fee.
  • Contract records “proof-of-victory” on-chain for DAM to query.
  1. Publish a multiplayer version of Flappy Bird connected to DAM as a proof of concept
  • Simple game that lets 2-10 players play flappy bird. The player who gets the furthest wins the pot.
  1. Implement a PUSH notification system for PVP Contract
  • Notifications to winners and losers involved in a competitive match. Includes the amount of crypto that was spent and how much (if any) was won.

Future Phases (these are not included as deliverables in the current funding round)

  1. Create API for web2 games to easily implement PVP contracts. The current solution is more web3 friendly.
  2. Create an NFT marketplace for in-game assets with PUSH notifications
  3. Implement a PUSH chat lobby for players that join a game
  4. Design Metaverse experience in Unity

This proposal shows a deep knowledge of the industry and a thorough plan for execution. I believe there is a large market at stake, which this proposal can help tackle.

Of all the proposals I’ve read, this one deserves to be funded/built. There is an excellent team with the background for creating this type of product. I can’t wait to see this project get funding and come to market.


Thank you for your kind words! We are just as excited to build DAM. It’s a solution that can’t be built using web2 and really shows the power of programmable money in web3!

Thankful for all the help
Currently working on our first game
looking forward to showing you guys what we are building for DAM!

Thank you so much for joining Office hours today and explaining DAM in detail.

From my point of view the value proposition for Push is very clear and very attractive. Game developers who decide to turn on the switch will immediately be offering Web3 communication to players through Push Protocol. And there are plenty of use cases that can derive from marketplaces and game basic functions.

Are you connected to game developer communities or groups that can serve as alpha testers for the initial release? Have you been in conversations with them?

Also - maybe is a bit too early to think about this - , but have you given thoughts to your strategy to attract more game developers to implement DAM?

The office hours were great, thank you for the invite! Looking forward to joining more in the future!

We have a few game devs in our network already that we ran our idea by for validation and were met with resoundingly positive feedback, but we havent began any aggressive outreach or sales process.

We have a decent sized cohort of gamers to test our first MVP which will be a Flappy Bird style multiplayer game that has the PVP contract functionality. Itll be on testnet at first so theyll be playing for free and we can use $DAM airdrops to incentivize this activity.

We plan to use this test phase to attract game developers and publishers with existing games on the market and focus on supporting integrations. DAM gets better with the more games available so this is going to be a top priority once we’re ready.

To game studios we have 4 main value propositions:

  • 3% of every game their community plays can scale to making more than a game does in physical sales.
  • They can set a variable royalty fee NFT collectables and skins to create liquid markets for game assets.
  • We modernize their company and integrate web3 which can make them more attractive to future investors and players.
  • Launching eSports leagues can run millions of dollars and take years to become profitable. Games can implement an eSports scene through us with ease. Play, watch, stream, and win.

Thanks for the great questions! Let me know if theres anything else thats unclear. We’re super excited to get this off the ground :grin:
