A downward arrow labeled “Drawings and materials quantity” points to a label “B C”. Surrounding “B C”, three box icons are shown arranged in a circular manner and connected in a circular flow with a curved arrow. From “B C”, a double-headed arrow labeled “Transparency” and “Traceability” points to a box labeled “Owner”, illustrated with a person icon. Likewise, from “B C”, a double-headed arrow extends leftward, labeled “Market price” and “Product” and points to a box labeled “Supplier”, shown with a delivery truck icon. From “B C”, an arrow extends downward and points to a box labeled “Peers”, which includes a document icon. From “Peers”, an upward arrow labeled “Interaction without delay” points back to “B C”. From the downward arrow arising from “B C”, a rightward pointing arrow labeled “Smart Contract” arises and points to a box labeled “1. Real-time monitoring” and “2. Order on demand”. On the left side of “Peers”, a small box labeled “Labor”, containing a construction worker icon, is shown. From “Labor”, a rightward pointing arrow with a box icon points to “Peers”.
