Supplementary file 1_Impact-finance protocol for digital sustainable finance: institutional architecture for outcome-based capital allocation.pdf

Yet the infrastructures linking trusted representations of real-world social and ecological performance to financial decision-making remain underdeveloped. This challenge is particularly acute within sustainable, impact and development finance, where capital allocation continues to rely heavily on retrospective reporting, proxy indicators and fragmented information flows.</p>Methods<p>This study addresses this gap through a design science approach, developing an Impact-Finance Protocol as a conceptual systems architecture for Digital Sustainable Finance.

Drawing on systems mapping, comparative protocol analysis and the Integrated Capitals Assessment (ICA) framework, the research identifies the functional requirements for translating verified non-financial performance into adaptive financial processes.</p>Results<p>The resulting architecture comprises six interdependent protocol layers encompassing data, logic, value, governance, community and assessment. Together, these establish an integrated infrastructure through which verified impact information can inform financial decision-making, capital allocation and institutional governance within continuous feedback systems.</p>Discussion<p>Rather than proposing a new financial instrument, the protocol reconceptualises finance as an adaptive information system in which trusted digital infrastructure enables financial flows to respond dynamically to verified real-world conditions.
