### Objectives of Study  
This study proposes a blockchain-based system optimized for managing small-scale Digital Asset Trading Platforms (DATPs). Before presenting the proposed approach, it is important to explain why this study focuses on blockchain-based platform management, particularly why small-scale platforms are emphasized. First, the need for blockchain-based platform management stems from the ability to leverage blockchain's decentralized nature to neutralize platform governance. Platform monopolization often has detrimental effects: it restricts fair competition by creating barriers for new entrants and stifling innovation. Users are compelled to conform to monopolistic platform policies and pricing, which limits choice, while the risk of data misuse for private gain raises privacy concerns. Moreover, limited transparency in decision-making can lead to decisions that overlook user needs, ultimately hindering the platform's potential for broad adoption across diverse fields. Next, this study focuses on small-scale platforms because blockchain-based tokenization is highly dependent on the characteristics of the associated physical assets, making it likely that platforms facilitating the trade of tokenized assets will be small in scale. In other words, a specialized small-scale platform tailored to specific physical assets is expected to be necessary. The blockchain-based tokenization model assumed in this study goes beyond merely recording the transfer of digital asset ownership; rather, it considers cases where transactions of blockchain-based tokens directly affect the ownership rights of the corresponding physical assets. For instance, if a tokenized digital asset represents the right to operate a specific electric vehicle, ownership of the token on the blockchain serves as definitive proof of the right to use the vehicle. In such cases, the tokenization process is influenced not only by the attributes of the digital asset but also by the characteristics of the associated physical asset. Therefore, a DATP must account not only for digital token transactions but also for the operational rights of the physical asset--such as driving range, usage duration, and liability--alongside the specific characteristics of the individual vehicle. Given these considerations, small-scale platforms designed for specific assets are expected to be more effective and more widely adopted than large-scale platforms. Thus, this study's exploration of blockchain methods tailored to small-scale platforms for trading specific tokenized assets is particularly valuable and contributes to the growing field of asset-specific digital trading platforms. One of the primary challenges in converting a small-scale platform that trades physical assets or associated rights into a blockchain-based tokenized asset trading platform is the high operational cost associated with blockchain technology. For instance, ensuring the reliability of the platform chain (the blockchain that governs the operation of the tokenized asset trading platform) by incentivizing a large number of participants to engage in block mining is particularly challenging for platform chains designed for small-scale digital asset trading. This is because, if the incentives are insufficient, the number of participants will decrease, making it difficult for the blockchain to satisfy conditions **C1**, **C2**, and **C3** at any meaningful capacity. Conversely, if the rewards are set too high, the operational costs of the platform chain will increase, thus reducing the benefits of adopting the platform chain. Most existing blockchain projects seek to mitigate this cost issue through the use of native cryptocurrencies. However, for this model to be sustainable, it relies on the assumption that the value of the cryptocurrency will continuously increase or at least remain stable. This assumption is often unrealistic, and without it, most blockchain networks cannot sustain their operations.
