Michael Saylor Outlines a Five-Layer Framework Built on Bitcoin as Digital Capital

Strategy founder Michael Saylor proposed a “Modern Digital Asset Stack” framework that positions Bitcoin as the foundational layer of digital capital. According to Foresight News, the model defines Bitcoin as the base asset and describes five layers built above it to serve different risk and return preferences. Saylor described the bottom layer as Digital Capital, referring to Bitcoin itself as a scarce base asset. Above that, he outlined Digital Credit, citing Bitcoin-backed yield instruments such as STRC-like products that aim to reduce volatility through capital structure. He then described Digital Money as stable-value yield tools that combine digital credit with fiat equivalents. The fourth layer, Digital Yield, covers higher-risk, higher-return leveraged or structured products. The top layer, Digital Equity, includes equity-style exposure similar to MSTR, intended to absorb residual volatility and capture upside. Saylor said the framework does not require changes to the Bitcoin protocol, arguing instead that innovation in capital markets built on top of Bitcoin can broaden participation in the Bitcoin ecosystem across varying risk appetites.
