“…As a result, such IoT devices can store faulty, incomplete, or imprecise waste management-related data on the blockchain. Making correct decisions in the context of waste management policies using such immutable garbage data becomes challenging and often results in inefficient waste resources management and economic losses [70], [71]. The resource-constrained IoT devices cannot directly communicate to the blockchain network; instead, edge nodes generate transactions to the blockchain for storing or receiving data on the behalf of IoT devices via wired or wireless links and various protocols such as HTTPS or TCP/UDP-based protocols.…”

Smart cities have the potential to overcome environmental problems caused by improper waste disposal by improving human health, protecting the aquatic ecosystem, and reducing air pollution. However, today's systems, approaches, and technologies leveraged for waste management are manual and centralized. This fact makes them vulnerable to manipulation and the single point of failure problem. Also, a large portion of the existing waste management systems within smart cities fall short in providing operational transparency, traceability, audit, security, and trusted data provenance features. In this paper, we explore the key role of blockchain technology in managing waste within smart cities as it can offer traceability, immutability, transparency, and audit features in a decentralized, trusted, and secure manner. We discuss the opportunities brought about by blockchain technology in various waste management use cases and application scenarios, including real-time tracing and tracking of waste, reliable channelization and compliance with waste treatment laws, efficient waste resources management, protection of waste management documentation, and fleet management. We introduce a framework that leverages blockchainbased smart contracts to automate the key services in terms of waste management of smart cities. We compare the existing blockchain-based waste management solutions based on important parameters. Furthermore, we present insightful discussions on several ongoing blockchain-based research projects and case studies to highlight the practicability of blockchain in waste management. Finally, we present open challenges that act as future research directions.

“…A great deal of research has been done on blockchain due to its enormous potential for the construction sector [2][3][4][5]20]. The latest literature reviews on AEC-related applications of blockchain identify different research priorities and use cases [2][3][4][5]20,37].…”

“…The high complexity and structural fragmentation of the sector, the limited degree of repeatability of construction projects, weak collaboration, and insufficient investment in innovation are the most common reasons for the low level of digitization and productivity [1]. Blockchain is predicted to be a technology that could have an extremely positive force of change in the architectural, engineering, and construction (AEC) industry [2][3][4]. The potential of blockchain has been recognized in the scientific community and is getting more and more attention [2,3,5,6].…”

“…Notwithstanding the great scientific interest in this area, there is widespread skepticism about the usability, acceptance, and readiness of the AEC industry for adoption of blockchain solutions [2,3,20]. Regarding this matter, this contribution focuses on the question of how BIM can be combined with blockchain-based smart contracts to reach a practicable and enforceable solution for automated payment between clients and contractors.…”

Automated Payment and Contract Management in the Construction Industry by Integrating Building Information Modeling and Blockchain-Based Smart Contracts

Construction projects usually involve signing various contracts with specific billing procedures. In practice, dealing with complex contract structures causes significant problems, especially with regard to timely payment and guaranteed cash flow. Furthermore, a lack of transparency leads to a loss of trust. As a result, late or non-payment is a common problem in the construction industry. This paper presents the concept of implementing smart contracts for automated, transparent, and traceable payment processing for construction projects. Automated billing is achieved by combining Building Information Modeling (BIM) approaches with blockchain-based smart contracts. Thereby, parts of traditional construction contracts are transferred to a smart contract. The smart contract is set up using digital BIM-based tender documents and contains all of the relevant data for financial transactions. Once the contracted construction work has been accepted by the client, payments can be made automatically via authorized financial institutions. This paper describes the framework, referred to as BIMcontracts, the container-based data exchange, and the digital contract management workflow. It discusses the industry-specific requirements for blockchain and data storage and explains which technical and software architectural decisions were made. A case study is used to demonstrate the current implementation of the concept.
