- The estimation of the risks’ impact, expressed through three impact levels: LOW, MEDIUM, and HIGH.
4. Discussion
- Blockchain platform: More specifically, the platform Energy Web (EW Chain) [2] is the world’s first open-source enterprise blockchain platform tailored to the needs of the energy sector. As mentioned, the EW-chain is a PoA public blockchain derived from Ethereum blockchain technology, ensuring low energy consumption and efficiency. Since it is EVM-based, solidity can be used to materialise the business logic of each business model into a new smart contract. The Decentralized Data Exchange (DDEx) service supports high-volume, low-latency on-chain transactions, and the DID-based authentication and authorization mechanism provides for trusted and secure participation in energy transactions. The EW chain can be scaled up to support any energy-related use case and will be employed to record the output of all energy service transactions. EW Chain has extremely low transaction costs, stemming from its low instantaneous power draw that is about 7.5 kilowatts, with 50 validator nodes spread across the globe. In comparison, Ethereum draws roughly 1,000,000 times more power, and Bitcoin consumes roughly 2.2 million times more power than EW Chain.
- Smart Contracts service: The Smart Contracts generator follows the factory contract [185] pattern [“https://research.csiro.au/blockchainpatterns/general-patterns/contract-structural-patterns/factory-contract/, accessed on 18 June 2025”] and allows for increased security during the contracts generation, legal compliance and interoperable reporting of energy KPIs. The currently existing paper-based Service Level Agreements (SLAs) for meeting energy KPIs will meet their digital twin on the EW chain, moving closer to legally binding smart contracts. This bridging between the off-chain physical agreement and the on-chain smart contract will enforce secure storage and execution of the SLAs as well as the auditability of historical transactions related to the legal contract and the contract itself in an interoperable fashion. It is important to note that while InEExS contracts aim to enhance transparency and legal clarity, the legal enforceability of any contract, ultimately depends on the jurisdiction in which it is subject to interpretation and enforcement—in our case the InEExS business cases.
- Tokenisation service: extension service of the EW Chain, which has already been deployed in commercial applications to allow token holders to pay for decentralized application services, by using the native cryptocurrency of the EW Chain that is the Energy Web Token (EWT). Within InEExS, EWTs will also be used to tokenize the verified savings and flexibility as contribution of participants in energy services transactions.
- (1)
- Standardisation of grid integration frameworks for renewables and distributed energy sources, involving the creation of national frameworks for integrating renewables and DERs into the grid, ensuring uniform rules for feed-in tariffs and clear guidelines for P2P energy trading through blockchain technology.
- (2)
- Development of GDPR-compliant energy data platforms, involving the creation of secure, interoperable blockchain-based platforms for energy-data sharing that comply with GDPR while enabling real-time optimisation.
- (3)
- Providing consistent support for energy communities by ensuring legal recognition and providing administrative and financial support for energy communities, while also promoting energy efficient behaviour and self-consumption optimisation through blockchain exploitation.
- (4)
- Updating building regulations by revising national building codes to mandate retrofits for energy efficiency and provide financial incentives for compliance that can be combined with P4P guarantees enabled through blockchain.
- (5)
- Enabling demand response and consumer-compensation mechanisms by establishing clear national frameworks and blockchain-based compensation mechanisms for consumer participation in demand-response programs.
- (6)
- Balancing natural gas transition policies by incorporating interim support for improving natural gas systems during the transition to renewable energy.

Focus Area | Key Findings | Study |
---|---|---|
Benefits of blockchain as an alternative to digital payments and cryptocurrency investment business. | With internationally recognized safeguards of confidentiality and the ease of conducting investment transactions and activities without payment, the weaknesses and threats can be controlled for more investors to enter the world. | [55] |
Analysis of the economic perspectives of the blockchain technology in agricultural business. | Blockchain technology has big opportunities in agricultural business and agri-food supply chain in the digital economy; however, there is a research gap related to financing the blockchain implementation and cooperation between businesses and the authorities. | [56] |
Measurement of the stakeholders’ perceptions of the P2P energy trading model using blockchain technology. | The P2P energy trading model using blockchain technology is believed by stakeholders to provide greater benefits to the user community, expand opportunities to consume renewable energy, and contribute to reducing climate change in Indonesia. | [57] |
Evaluating the barriers to blockchain adoption in the energy sector using the SWOT and PESTLE tools and the Analytical Hierarchy Process for Group Decision Making. | Main barriers include legal issues, particularly complex regulations, followed by technological security risks, sociopolitical risk aversion, and high initial costs. The SWOT analysis further helped stakeholders provide a comprehensive understanding of the advantages, challenges, and risks involved, and it guided the development of strategies to address these barriers. | [58] |
Evaluating the blockchain technology strategies for reducing renewable energy development risks. Integration of SWOT analysis and hybrid MCDM methods in the proposed framework. | The key finding is that blockchain technology can help reduce renewable energy development risks by creating a decentralized energy system, lowering costs, and eliminating monopolies. | [59] |
Examination of the current state of blockchain and smart contracts technology in the energy sector, focusing on use cases, key challenges, and potential solutions through SWOT. | The adoption of smart contracts and blockchain in the energy sector offers significant potential for enhancing efficiency, security, and transparency, but successful implementation depends on addressing challenges such as high initial costs, technical complexities, and evolving legal requirements through strategic planning, stakeholder collaboration, and the development of flexible frameworks. | [60] |

Characteristic | Description |
---|---|
Decentralisation | Traditional centralised transaction systems require validation from a central trusted entity, resulting in performance bottlenecks. In contrast, blockchain eliminates the need for a third-party central trusted agency, since data consistency is ensured by the consensus algorithm [71,72]. |
Persistence | Transactions are swiftly validated, and honest nodes reject invalid transactions. Once included in the blockchain, it is nearly impossible to delete or rollback transactions. Any blocks containing invalid transactions can be promptly identified [73]. |
Anonymity | Users interact with the blockchain using generated addresses, preserving their real identities. However, perfect privacy preservation is not guaranteed due to inherent limitations [74,75]. |
Auditability | Every transaction refers to previously implemented transactions that have not been spent yet. When these transactions are added to the blockchain, their status changes from unspent to spent. This facilitates straightforward validation and the tracing of transactions [74,76]. |
