Blockchain for Cities—A Systematic Literature Review

Blockchain is considered one of the most disruptive technologies of our time. Numerous cities around the world are launching blockchain initiatives as part of the overall efforts toward shaping the urban future. However, the infancy stage of the blockchain industry leads to a severe gap between the knowledge we have and the actions urban policy makers are taking. This paper is an effort to narrow this rift. We provide a systematic literature review on concrete blockchain use cases proposed by the research community. At the macro-level, we discuss and organize use cases from 159 selected papers into nine sectors recognized as crucial for sustainable and smart urban future. At the micro-level, we identify a component-based framework and analyze the design and prototypes of blockchain systems studied in a subset of 71 papers. The high-level use case review allows us to illustrate the relationship between them and the four pillars of urban sustainability: social, economic, environmental, and governmental. The system level analysis helps us highlight interesting inconsistencies between well-known blockchain applicability decision rules and the approaches taken by the literature. We also offer two classification methodologies for blockchain use cases and elaborate on how they can be applied to stimulate cross-sector insights in the blockchain knowledge domain.INDEX TERMS Bitcoin, blockchain, computer networks, consensus, crypto token, distributed computing, Ethereum, Hyperledger Fabric, systematic literature review, smart city, smart contract, system analysis and design, peer-to-peer computing, urban sustainability, use case.

“…The most prominent energy blockchain applications include peer-to-peer trading, electric vehicle charging, sustainability rewards, prepaid metering, energy performance, and demand-side management, to name a few [4]. Of these applications, peer-to-peer and transactive energy trading for smart grids and microgrids represent some of the most compelling and researched use cases, with research contributions focusing on efficient and robust designs to facilitate energy transactions across communities and wholesale markets [5][6][7][8][9].…”

“…This includes the establishment of information streams between physical metering and energy blockchains, which has been highlighted as an important challenge for system regulators and energy providers [3]. Indeed, blockchains cannot be operationalised in real-world energy operations without sufficient cooperation between energy providers, grid operators and government agencies [4].…”

The application of blockchain technology to the energy sector promises to derive new operating models focused on local generation and sustainable practices, which are driven by peer-to-peer collaboration and community engagement. However, real-world energy blockchains differ from typical blockchain networks insofar as they must interoperate with grid infrastructure, adhere to energy regulations, and embody engineering principles. Naturally, these additional dimensions make real-world energy blockchains highly dependent on the participation of grid operators, engineers, and energy providers. Although much theoretical and proof-of-concept research has been published on energy blockchains, this research aims to establish a lens on real-world projects and implementations that may inform the alignment of academic and industry research agendas. This research classifies 131 real-world energy blockchain initiatives to develop an understanding of how blockchains are being applied to the energy domain, what type of failure rates can be observed from recently reported initiatives, and what level of technical and theoretical details are reported for real-world deployments. The results presented from the systematic analysis highlight that real-world energy blockchains are (a) growing exponentially year-on-year, (b) producing relatively low failure/drop-off rates (~7% since 2015), and (c) demonstrating information sharing protocols that produce content with insufficient technical and theoretical depth.

“…Currently, the implementation of decentralized market platforms is possible due to new advances in information and communication technology, such as blockchain and other distributed ledger technologies (DLTs), which support transparent and decentralized transactions. Many studies have already considered DLTs as the base of their P2P energy trading platforms [3], [4]. For example, [5] proposed a P2P energy trading model for electrical vehicles, showing the potential of blockchain to enhance cybersecurity on the P2P transactions.…”

The increasing uptake of distributed energy resources (DERs) in distribution systems and the rapid advance of technology have established new scenarios in the operation of lowvoltage networks. In particular, recent trends in cryptocurrencies and blockchain have led to a proliferation of peer-to-peer (P2P) energy trading schemes, which allow the exchange of energy between the neighbors without any intervention of a conventional intermediary in the transactions. Nevertheless, far too little attention has been paid to the technical constraints of the network under this scenario. A major challenge to implementing P2P energy trading is that of ensuring that network constraints are not violated during the energy exchange. This paper proposes a methodology based on sensitivity analysis to assess the impact of P2P transactions on the network and to guarantee an exchange of energy that does not violate network constraints. The proposed method is tested on a typical UK low-voltage network. The results show that our method ensures that energy is exchanged between users under the P2P scheme without violating the network constraints, and that users can still capture the economic benefits of the P2P architecture.
