Project Overview 📄​

Overview​

Introduction​

SubGame is a decentralized game platform. There are a large number of game templates running on the platform, so that participants can quickly start the game. The NPOS consensus mechanism is adopted to ensure the fairness of the entire platform. After the mainnet is launched, community autonomy allows the entire ecosystem Cycle forward. SubGame will also provide a friendly game front end, allowing players to enjoy the joy of the game.

The early stage will be based on quiz and probability game templates. For example, you can choose a random factor to create a guessing game and play with your friends. You can also play World Cup quiz with your own friends, and of course you can also buy lottery tickets on it. The above games all exist as templates, you can start the game or participate in other people’s games

Integration​

SubGame is based on the Substrate 2.0 Framework. Substrate's powerful non-fork upgrade solution will provide more help to the changing game platform. We will also use OCW to introduce more game random factors. SubGame will serve as a parachain , To provide more possibilities for the entire Polkadot ecology

Team Interest​

All members of the team are convinced that blockchain will change the world, and have been working hard to create more transparent rules of the game. We have been observing and learning Substrate technology for more than a year. From the current point of view, substrate is our best choice.

Project Details​

Components​

The SubGame project contains SubName Node, Game Template Library, Gamee Chips, Game Center and Front End. modules

  • SubGame Node is the customized chain node for SubGame network build by Substrate 2.0 ,it contains the basic functionalities as a normal chain node but also provides the ability to fetch external data needed for games with the OCW (Off-chain Worker) from Substrate 2.0 Framework.
  • SubGame Token SGB∗∗isthenativetokenoftheSubGameNetwork,anditwillplaytheroleofgovernanceandotherutilities.∗∗SGB** is the native token of the SubGame Network, and it will play the role of governance and other utilities. **SGB like $DOT
  • Game Chips: is one of the core modules of SubGame, mainly including chips purchase, redemption and income distribution.
  • Game Template Library is an ever-increasing library of game templates, and new game additions continue to increase through public chain upgrades. for
  • Game Center stores all game instances and player data. It is the data center of the entire platform
  • Front End will adapt to the basic game front end to ensure a friendly user experience

Scenarios​

  • Scenario to buy chips and transfer

transfer

As shown above, we will realize the chip exchange of $SGB in the first stage, and the ETH exchange in the later stage, and the chips of each address can also be freely transferred

  • Scenario to create new game and play games

playgames

Players can build their own games or participate in other people’s games. Each game has a gameplay designed in the pallet-gametemplates. The first pallet-gametemplates will be continuously designed and adjusted during the first development stage.

First Game Template​

  • Template Name: Guess

  • Design

    • Random factor: the hash string of the future block
    • Gameplay:
      1. Players create a new game instance and set parameters
        1. Block number used for guessing
        2. The smallest and largest bet amount
        3. Game odds
        4. Chips amount
      2. All players can participate in the game and bet before the guessed block appears
      3. When the target block is generated, the game chips are settled according to the game rules on the chain (this logic can be written in decl_module -> on_finalize)

  • UI mock-ups

    mock-ups

  • The hash string of the future block: This random factor can actually be modified a lot to make more interesting games, such as lottery games.

  • In addition to the above-mentioned future block hash as a random factor, we can still introduce off-chain data through OCW from the game design, for example, we want to guess the World Cup or NBA The imagination of the game is endless, but the core of our first phase is to create a fair and reasonable distribution of benefits, and we will continue to increase game templates.

Ecosystem Fit​

At present, there is no real decentralized game platform, but more decentralized games. Unlike the past, this time we are going to build a truly decentralized game ecological platform.
