There are one and a half million properties on the National Register as historic landmarks, and probably 10 times more on state and local registers. Each of them may have an intangible value ranging from tens of thousands of dollars to a few million dollars. The total value of intangible assets of historic landmarks, therefore, should be in hundreds of billions dollar range, and may be over a trillion dollars. Prominent historic landmarks can usually monetize their intangible value from tourism and sales of franchised commodities, such as books, videos, and souvenirs. The majority of historic landmark properties, however, lack the renown to draw significant tourist traffic or generate meaningful merchandise sales. Most of their intangible values are untapped. Great Estate Blockchain develops solutions which will combine crypto token strategy with short-term rental business model to monetize the intangible value of these historic landmarks.
