The paper presents a new digital infrastructure layer for buildings and architectural assets.
The infrastructure layer consists of a combination of topology graphs secured on a
decentralised ledger. The topology graphs organise non-fungible digital tokens which each
represent and correspond to building components, and in the root of the graph to the
building itself. The paper presents background research in the relationship of building
representation in the form of graphs with topology, of both manifold and non manifold nature …
