Bitcoin Magazine published an article delving into business models for digital credit, digital currency, and digital yield based on Bitcoin balance sheets. The article defines "digital credit" as Bitcoin-denominated credit instruments issued by companies, citing five Nasdaq-listed perpetual preferred stocks (STRC, SATA, STRK, STRF, STRD) as examples. "Digital currency" refers to stablecoin-denominated products based on digital credit, while "digital yield" refers to products that amplify digital credit returns. The article also describes two main architectures: debt tranching structures (such as the Saturn/Strata protocol, with UTXO Preferred Income Strategies LP offering a 7.5% annualized yield) and full-reserve spendable balance structures.
