... In simple terms, a cost of trust is referred to as 'trust cost'. Therefore, as ICT has extended the sphere of consumers in the global energy value chain with the ability to generate and trade energy over the Internet, trustworthiness has come under stress among participants in the DET value chains (Shyamasundar and Patil 2018). Although the invention of blockchain seems to have addressed the trust issue with distributed control, transparency, and provenance, the available blockchain frameworks incur high communication and computation cost. ...
The increasing adoption of clean energy technologies, including solar and wind generation, demand response, energy efficiency, and energy storage (e.g. batteries and electric vehicles) have led to the evolution of the traditional electricity markets from centralised energy trading systems into Distributed Energy Trading (DET) systems. Consequently, savvy business executives are exploring how blockchain might impact their competitive advantage in the emerging DET markets. Due to its salient features of distributed ledger, consensus mechanisms, cryptography, and smart contracts, blockchain technology is being used to provide decentralised trust, immutability, security and privacy, and transparency in DET system. However, integrating blockchain in DET systems is facing technical, administrative, standardisation and economic barriers. Consequently, we seek to conduct a comprehensive market analysis to identify the specific challenges hindering the integration of blockchain in DET systems. Nonetheless, we noticed that there isn't any evaluation and review framework for conducting a systematic literature review on blockchain-based DET systems. Therefore, in this work we first proposed a conceptual evaluation and review framework for conducting a systematic literature review on blockchain-based DET systems. Then, using the proposed framework, we reviewed the current studies on blockchain-based DET systems to the identify specific challenges hindering the adoption of blockchain and their proposed solutions. Our review found that, although there has been tremendous progress in addressing the technical barriers, the administrative, standardisation and economic barriers have grossly been under reviewed.
... While confidentiality mechanisms can be enforced, these systems fall short in maintaining an immutable trail of operations performed on land records, because tuples in a database can be overwritten. Double-entry book-keeping is used in identifying discrepancies in records, however malicious records can only be traced with the help of a digital log management system, which in turn is susceptible to tampering [18]. Tripleentry book-keeping can be adopted, where each transaction is digitally signed by the subject of transaction; irrespective of the transaction being valid, erroneous or malicious -thus fixing accountability. ...
Blockchains ensure integrity, transparency, and immutability of transactions they process. It also guarantees the eventual inclusion of all the transactions submitted to the blockchain and records them in its ledger. Bitcoin and Litecoin are examples of time-tested, reliable public blockchains that handle only one type of transaction – send/receive money (i.e., transfer-of-value) from one user to another. Whereas, general-purpose blockchains like Ethereum provide means and methods to encapsulate transfer of not only value but anything fungible that can be digitally represented with the help of programs aka smart contracts. However, with a high-level Turing-complete programming language to write smart contracts, Ethereum encountered vulnerabilities in its contracts thus forgoing the claim of immutability. On the contrary, script-based blockchains like Bitcoin and Litecoin have withstood the test of time and hence are perceived reliable – a very important aspect while managing assets like land. In this paper, we present a transfer-of-asset system for land management that borrows from Litecoin protocol its script, underlying consensus, and block structure. Our resultant system is a permissioned blockchain, where only a set of pre-approved miners can append land records to the blockchain. We introduce sidechains that are roped in a mainchain. The mainchain stores land records, which can be queried by citizens; whereas, sidechains hold intricate details about intermediate validations performed by regulators, registrars, and notaries. The process of land management used in this paper is a typical process in the states of India. Our system can be used to manage any asset class that is finite in nature. Our approach provides transparency of transactions at a higher level and privacy to individual transactions.
