SDA Methodology: Tokenization of the Value Creation Chain A Method of Engineering Design for Digital Economic Constructions

Abstract

This paper introduces the SDA (Structured Digital Assets) methodology for tokenizing value creation chains — a novel approach to Real World Asset (RWA) tokenization where the object of tokenization is not a static asset but the dynamic process of economic value creation. Unlike conventional tokenization models that digitize ownership rights to existing assets, SDA treats each stage of a production chain as a separate tokenizable unit with mathematically defined value accumulation. The methodology integrates value chain theory, structured finance principles, institutional economics, and distributed ledger technology into a unified framework for engineering digital economic constructions.
