Wu Shuo learned that Strategy founder Michael Saylor recently published an article proposing a five-layer architecture of the "Modern Digital Asset Stack" based on Bitcoin. The architecture is sequentially: digital capital (BTC), digital credit (such as STRC yield tools), digital currency (stable yield tools combining fiat liquidity), digital yield (leverage and structured products), and digital equity (stock assets like MSTR that absorb volatility). Saylor stated that this system does not require changing the underlying Bitcoin protocol and can transform BTC's inherent volatility into financial products that meet various investors' needs, which is a key pathway for Bitcoin to integrate into the global financial infrastructure.
