PANews reported on June 16 that Strategy founder Michael Saylor published a lengthy article on the X platform, proposing a five-layer architecture for the modern digital asset stack: digital capital (BTC), digital credit (Bitcoin-backed yield instruments), digital currency (stable-value yield instruments), digital yield (leveraged or structured products), and digital equity (MSTR-style residual equity).

Saylor argues that Bitcoin itself does not need to generate returns, nor does it require staking, inflation, or protocol changes. Returns should be created through capital structures built upon Bitcoin. Digital currency combines digital credit with fiat currency cash equivalents to form a stable, daily-liquid, and yielding instrument with a target return of 6-8%. This architecture does not alter Bitcoin's underlying structure or weaken its core principles; rather, it expands Bitcoin from a single asset into a global financial infrastructure through capital markets.
