The "GPT Moment" of Stablecoins: Blockchain Drives Transformation in Finance and Public Sectors

Although blockchain technology originated from anti-establishment ideas, it has gradually moved towards the mainstream in recent years. The year 2025 may become the "ChatGPT moment" for the application of blockchain in the financial and public sectors, primarily driven by the demand for regulatory clarity and transparency.

Stablecoins, as an important component of the Blockchain ecosystem, are expected to continue to grow rapidly. By 2030, the total supply of stablecoins could reach $1.6 trillion in the baseline scenario and as high as $3.7 trillion in the optimistic scenario. The U.S. dollar will remain dominant, accounting for about 90%.

The growth of stablecoins will create new business opportunities for banks, but it may also pose a threat to traditional deposit businesses. The introduction of a regulatory framework for stablecoins in the United States is expected to drive new demand for U.S. Treasury securities, making stablecoin issuers one of the main holders of U.S. Treasury bonds.

The application prospects of blockchain technology in the public sector are broad, with main use cases including:

• Public Expenditure Tracking and Financial Management
• Funding and subsidy distribution
• Public Record Management
• Humanitarian Aid
• Asset Tokenization
• Digital Identity

These applications are expected to enhance the transparency, efficiency, and accountability of government operations. Although the on-chain transaction volume in the public sector may initially be small, its increasing interest is an important signal for the broader application of Blockchain.

However, the large-scale application of Blockchain in the public sector still faces many challenges, including: lack of trust, interoperability and scalability issues, difficulty in transformation, regulatory uncertainty, risk of abuse, etc.

In general, with the clarification of regulatory frameworks and the maturity of technology, Blockchain is expected to reshape the operations of the financial and public sectors in the next 5-10 years, bringing profound impacts.
