Limestone Network is a blockchain infrastructure for modern cities.
We called cities powered by Limestone Network, smart cities.

Smart City
We believe that to build a smart and efficient city, the city first needs to be understood. It starts by having a digital ecosystem that allows real time analysis of living and moving data. The end result is a greener city through optimal energy production, enhanced security via distributed ledger technology and an urban civilization that provides efficiency yet with simplicity.


As ardent technologist, the founders created Limestone Network with the vision to transform the long established real estate industry with smart digital capabilities.

The is achieved by integrating blockchain technology to the physical real estate assets. Thus forming a digital network that connects urban cities into the daily lives of the residents that exchanged information seamlessly in the background to bring convenience, efficiency and enhance security to their day to day business and life.

Proposed Solution
Through the expertise of the team and their network in the industry, Limestone Technology aims to build a smart-city ecosystem for real estate developments and infrastructure across South East Asia

This will be accomplished through the digitalisation of the city via the development of a blockchain infrastructure - Limestone Network.

Our team envisioned Limestone Network to be the final solution that resolves existing challenges faced by governments, real estate developers and estate management service providers. When Limestone Network is implemented into a real estate project or existing infrastructure, we allow the facilities management to be taken to a simpler yet more secured level. Businesses, retail shops, building facilities, consumers, tourists and the daily visitors would be able to interact with each other in a smarter and more effective manner to provide a meaningful Smart City experience.


Digital Passport
Residents who work or reside in the city are required to register themselves with the Limestone mobile app. The submitted identities are then verified automatically through application programming interface (API) and added to the blockchain of Limestone Network.
Digital Wallet
Limestone digital wallet is setup to hold mutiple currencies of the solution providers within the cities. It will automatically be available to residents who have registered themselves over the digital passport. Residents will be able to make payment within the cities’ ecosystem.
With both physical and digital infrastructure to welcome third party, blockchain solutions, Limestone Network will partner with good blockchain projects by providing interoperability via the exchange for the Smart City.
Application Programming Interface (API) production
Limestone will invite third party developers and service providers to develop their blockchain applications on Limestone architecture to create a three-dimensional ecosystem to transfer contents and knowledge through an open API.

The Pilot Project

Limestone Network, an initiative of Global Tech Exchange, South East Asia real estate developer, will first be deployed in a city centre with up to 10,000 business tenants and 190,000 daily population, spanning across 20 hectares of work spaces, encompassing shopping malls, schools, retail outlets and housing the largest exhibition hall for business, it aims to be the financial hub, convention centre and go-to business place in the capital of Cambodia and thus giving this blockchian project a mandatory use case.
The concept of the Limestone Network (LSN), a blockchain technology application to a city development that creates an ecosystem that enables a secure and decentralized smart city environment.

This smart city development ecology is distinctively characterized by the extensive application of the blockchain technology. Relying on large amounts of data and other digital technologies, LSN aims to achieve a multi-faceted transformation of the urban ecosystem with intelligence and efficiency.
