In the upcoming era of distributed technological integration known as Web3, the built environment will need to adapt. Solving the most significant social, environmental and economic challenges will likely require new approaches to data sharing and efficient data management. This will need to occur within organizations, across software tools, and between partners. However, today’s approach of data fragmentation and a scattered system of data islands prevent efficient data usage in the construction industry.The question that now arises is whether the decentralized marketplace approach has the potential to make construction data sets more uniform, efficient,and usable for all stakeholders through distributed technological integration.Therefore, this paper’s contribution isto provide a conceptual starting point and possible research stream approach towards thisquestion. Doing so by outlining current data management challenges and discussing themin comparison with already existing web3 approaches in research and industry.
The origins of digital money and blockchain technology goes back to the 1980s, but in the last decade, the blockchain technology gained large popularity in the financial sector with the appearance of cryptocurrencies such as Bitcoin. However, recently, many other fields of application have been recognized, particularly with the development of smart contracts. Among them is the possible application of blockchain technology in the domain of land administration, mostly as a tool for transparency in the developing countries and means to fight corruption. However, developed countries also find interest in launching pilot projects to test their applicability in land administration domain for reasons such as to increase the speed and reduce costs of the real property transactions through a more secure environment. In this paper, we analyse how transactions are handled in Serbian land administration and how this process may be supported by modern ledger technologies such as blockchain. In order to analyse how blockchain could be implemented to support transactions in land information systems (LIS), it is necessary to understand cadastral processes and transactions in LIS, as well as legislative and organizational aspects of LIS. Transactions in cadastre comprise many actors and utilize both alphanumeric (descriptive or legal) data and geospatial data about property boundaries on the cadastral map. Based on the determined requirements for the blockchain-based LIS, we propose a system architecture for its implementation. Such a system keeps track of transactions in LIS in an immutable and tamper-proof manner to increase the security of the system and consequently increase the speed of transactions, efficiency, and data integrity without a significant impact on the existing laws and regulations. The system is anticipated as a permissioned public blockchain implemented on top of the Ethereum network.
This research in progress discusses two country use cases of land record modernization by adopting blockchain technology. Through the cases in Honduras and Georgia, we examine how socio-political and technical issues influence the IS readiness of public o
Long Finance’s Distributed Futures research programme is pleased to announce the release of its first three approaches to ‘geo-stamping’, along with a short guide. Time-stamping is an important part of Smart Ledgers (aka block-chains with embedded code), an authoritative record of the time of a transaction. Geo-stamping is a mirror image, an authoritative record of the location of a transaction. Geo-stamping = time-stamping + geo-location information.
Long Finance’s Distributed Futures research programme has an open source project, “GeoGnomo” to research and share methods for geo-stamping. Geo-stamping benefits from having memorable ways of recording areas that also aid efficient retrieval. GeoGnomo has built-to-share three approaches for recording areal information, a Quaternary Triangular System, a Quaternary Rectangular System, and a Variable Rectangular System for geo-stamping. Each can be used to record geographic areas into a block-chain.
GeoGnomo provides source code and an online translation from latitude & longitude areas to geo-codes and back. Thus, block-chain applications have almost an instant ‘global post code’ or ‘global zip code’ system. By using consistent geo-coding data retrieval is easier. Users can share information easily – “tell the drone to come to F49PUR9B7-20”, a resolution of 7.6 metres.
This report was commissioned by the Cardano Foundation in November 2017 and is one of the first outputs from a series of projects in the Distributed Futures research programme. Michael Parsons, CEO of the Cardano Foundation, comments “Geo-stamping and time-stamping are two of the most important functions of Smart Ledgers. Our sponsorship of Distributed Future’s GeoGnomo project is directed at sharing mechanisms for geo-stamping that are memorable, aggregable, proximable, and scalable.”
This chapter expounds the main principles behind blockchain technology and some of its cutting-edge applications. We first present the core concepts of the blockchain. Secondly, we discuss a definition put forward by Vitalik Buterin, we sketch out the shift toward hybrid solutions, and we sum up the main features of decentralized crypto-ledger platforms. Thirdly, we show why the blockchain is a disruptive and foundational technology, but we expose the potential risks and drawbacks of public distributed ledgers that account for the shift toward hybrid solutions. Finally, we present a non-exhaustive list of important applications, bearing in mind the most recent developments.
The introduction of Web GL standards accelerated the arrival of the Web3 D era. The generation and processing of3 D model is the core in Web3D project. On the basis of the three.js engine,the data drive modeling,importing and processing of static 3D model,and importing and analysis of dynamic 3D model in the Web environment are introduced. The experimental results show that the Web3 D technology based on Web GL platform and three.js engine can not only effectively achieve the data visualization and the database-oriented parametric modeling,but also has compatibleness with most of the industrial 3D models and support the whole Web3 D project.
