Last updated 29 days ago

The SCG project's technical architecture consists of a hybrid on-off-chain system based on a multi-layered design with the NFT chain as its core structure. This ensures high transaction efficiency and asset traceability, while flexibly accommodating real-time gameplay requirements arising from various sports games. SCG's main goal is to simultaneously achieve a balance between blockchain security and user experience throughout the technical architecture.

  1. Hybrid On-Chain/Off-Chain Processing Architecture

The hybrid on-chain/off-chain processing architecture of SCG is designed as a technical solution to simultaneously satisfy the blockchain-level asset security and the real-time responsiveness of game services. This structure is built on the high-speed processing capability of the Solana mainnet, and by handling frequent non-core operations off-chain, the system secures both efficiency and scalability.

  • Off-chain Logic Layer

Real-time board movement, animations, NPC responses, mission condition evaluations, and other UI and UX-related functions are processed on the client or game server side.

This layer is responsible for user experience–focused operations, and the server performs state synchronization with the on-chain system either periodically or event-driven.

  • On-chain Integrity Layer

Key transactions related to NFT creation, enhancement, combination, burning, reward claiming, league result recording, and governance voting are recorded on the Solana mainnet via smart contracts.

All on-chain transactions include verifiable hash values and timestamp data to ensure tamper resistance and traceability, guaranteeing immutability of user asset ownership and activity logs.

  • Chain Sync Trigger Engine (On-Off Chain Synchronization Mechanism)

The game client and server generate trigger events for state changes that require blockchain interaction (e.g., successful NFT combination, rewards from match results).

Only at this point is the on-chain record created. This approach minimizes blockchain call frequency and enhances responsiveness through integration with off-chain caching systems.

  • Asynchronous Integration via Message Queue

The data flow between on-chain and off-chain systems is connected asynchronously via message brokers (e.g., RabbitMQ, Kafka).

By parallelizing processing between request and result queues, server load is efficiently distributed.

This layered hybrid structure enables SCG to achieve high-level gameplay quality, data reliability, and the decentralized data integrity inherent to blockchain in a Web3 environment.

  1. Technical Core Structure of the NFT Chain

The NFT Chain in the SCG ecosystem is structured to provide users with high reliability and transparency, while simultaneously enabling efficient game operations. This structure is designed to meet both the trustworthiness of blockchain and the high-speed processing required for games.

The structure of the NFT Chain is composed of the following four key layers:

Player Interaction Layer The Player Interaction Layer is the top-level layer through which users interact with the game. Users manage NFT assets through the game interface and perform activities such as character development and league voting. This layer provides users with an intuitive and convenient gameplay experience.

Mirror NFT State Engine The Mirror NFT State Engine manages the real-time off-chain state of the game to provide high-speed processing and efficiency. It quickly processes frequently changing data—such as NFT asset levels, upgrades, and history—supporting the user’s gameplay experience without delays. This layer plays an essential role in minimizing blockchain transaction costs and processing time.

On-chain NFT Ledger Layer The On-Chain NFT Ledger Layer permanently records the ownership and critical information of NFTs on the blockchain, ensuring high transparency and reliability. Key transactions such as NFT minting, burning, and combination are recorded on the blockchain to protect the value of NFTs as immutable digital assets. This guarantees maximum trust in users’ assets and ensures transparency in all asset transactions.

Blockchain Infrastructure - Solana The Blockchain Infrastructure Layer utilizes Solana, which supports fast and cost-effective transaction processing. This allows for economical and rapid NFT transactions, ensuring the sustainability of the in-game economy. The infrastructure offers high throughput and low transaction fees, providing an efficient environment for both users and developers.

Through this layered architecture, the SCG ecosystem simultaneously enables a smooth gameplay experience and a trustworthy economic system. By combining fast off-chain processing with the high transparency of blockchain, it enhances technical efficiency and supports a sustainable ecosystem in which asset value is preserved and transparent economic activity is ensured.

  1. NFT Chain Game API Integration Structure

The API integration structure of the NFT Chain within the SCG ecosystem is designed to efficiently and transparently manage and process in-game asset operations and transactions. This structure consists of the following core components:

Game Client

The game client receives user requests and delivers various commands—such as NFT minting, enhancement, and status queries—to the NFT middleware API.

It acts as the player-facing interface that initiates all asset-related actions within the game.

NFT Middleware API

The NFT middleware API receives requests from the game client and appropriately routes them to the smart contracts and IPFS/metadata storage.

This layer increases efficiency and stability in executing blockchain transactions and managing metadata.

Smart Contract - Solana

The smart contracts, operating on the Solana blockchain, execute core transactions such as NFT issuance and record the on-chain state permanently.

This ensures the ownership and transaction transparency of digital assets.

IPFS/Metadata Storage

Metadata related to NFTs is stored in the decentralized IPFS system, increasing security and permanence of data.

Mirror NFT Engine

The Mirror NFT Engine performs real-time synchronization between on-chain and off-chain states, maintaining data consistency while supporting fast and accurate game state processing.

Through this integrated structure, the SCG ecosystem effectively supports the management and economic operation of NFT assets, providing users with high-level trust and a smooth gameplay experience.
