Limestone Network is a digitalisation initiative by Global Tech Exchange, a South East Asia real estate developer. It aims to address challenges faced by governments, real estate developers, and estate management service providers. By implementing Limestone Network into real estate projects and existing infrastructure, facilities management will become simpler and more secure. This initiative aims to enable businesses, retail shops, building facilities, consumers, tourists, and daily visitors to interact with each other in a smarter and more effective manner, offering a meaningful Smart City experience. The first deployment of Limestone Network will be in a city centre with 10,000 business tenants and a daily population of 190,000. Spanning across 20 hectares, it will include workspaces, shopping malls, schools, retail outlets, and the largest exhibition hall for business. Additionally, it aims to become the financial hub, convention centre, and go-to business place in the capital of Cambodia, providing a mandatory use case for this blockchain project.
