“…Small-sized CRS data, e.g., a smart meter's signature verification key, can be managed on the blockchain. On the other hand, large-sized CRS data, e.g., an evaluation key of the electricity-tracking proof, can be managed on a decentralized storage service, such as Arweave [60]. Therefore, the disadvantage (3) is permissible for ZGridBC.…”

The total number of solar power-producing facilities whose Feed-in Tariff (FIT) Program-based ten-year contracts will expire by 2023 is expected to reach approximately 1.65 million in Japan. If the facilities that produce or consume renewable energy would increase to reach a large number, e.g., two million, blockchain would not be capable of processing all the transactions. In this work, we propose a blockchainbased electricity-tracking platform for renewable energy, called 'ZGridBC,' which consists of mutually cooperative two novel decentralized schemes to solve scalability, storage cost, and privacy issues at the same time. One is the electricity production resource management, which is an efficient data management scheme that manages electricity production resources (EPRs) on the blockchain by using UTXO tokens extended to two-dimension (period and electricity amount) to prevent double-spending. The other is the electricity-tracking proof, which is a massive data aggregation scheme that significantly reduces the amount of data managed on the blockchain by using zero-knowledge proof (ZKP). Thereafter, we illustrate the architecture of ZGridBC, consider its scalability, security, and privacy, and illustrate the implementation of ZGridBC. Finally, we evaluate the scalability of ZGridBC, which handles two million electricity facilities with far less cost per environmental value compared with the price of the environmental value proposed by METI (= 0.3 yen/kWh).

“…As the term “weave” indicates, the blockweave does not have a simple chronological chain data structure. Each block in the blockweave is linked to two blocks: its previous block and a recall block – a randomly but deterministic selected block in the history of the weave (Williams et al. , n.d.).…”

“…Once the transaction is created, it is sent to a node in the Arweave network that validates the transaction and scans it against its content policy. A node's content policy allows for the rejection of certain types of data that might not comply with the rules in the jurisdiction in which the node operates (Williams et al. , n.d.).…”

Distributed records in the Rohingya refugee diaspora: Arweave and the R-Archive

PurposeThis article delineates the pilot implementation of the Rohingya Archive (R-Archive). The R-Archive seeks to both confront and exploit the roles of documentation and recordkeeping in forced displacement of Rohingya people through targeted physical and bureaucratic violence in Myanmar. This grassroots activist intervention is located at the intersection of technology, rights, records, jurisdictions and economics. Using Arweave's blockweave, the R-Archive secures copies of records, such as identity documentation, land deeds and personal papers, carried into diaspora by Rohingya refugees against unauthorised alteration, deletion and loss, providing a trust infrastructure for accumulating available evidence in support of rights claims and cultural preservation.Design/methodology/approachIterative development of functional requirements, data collection processes and identification of a technological solution for the community-based, post-custodial, blockchain-inspired R-Archive; design and testing of the R-Archive pilot; and analysis of trust and economic concerns arising.FindingsA complex set of interconnecting considerations is raised by this use of emerging technologies in service to a vulnerable and diasporic community. Hostile governments and volatile cryptocurrencies are both threats to the distributed post-custodial R-Archive. However, the strength of the community bonds that form the archive and articulated in its records speak to the possibility of perdurance for a global Rohingya archive, and working through the challenges surfaced by its development offers the possibility to serve as a model that might be adaptable for other grassroots archival activist projects initiated by oppressed, marginalised and diasporic communities.Research limitations/implicationsPersonal and community safety and accessibility concerns, especially in refugee camps and under Covid-19 restrictions, presented particular challenges to carrying out the research and development that are addressed in the research design and future research plans.Practical implicationsThe goal of this pilot was to collect and store examples of a range of documents that demonstrate different aspects of Rohingya culture and links to the homeland as well as those that record formal evidentiary relationships between members of the Rohingya community now in diaspora and the Burmese state (e.g. acknowledgements of citizenship). The pilot was intended to demonstrate the viability of using a blockchain-inspired decentralised archival system combined with a community-driven approach to data collection and then to evaluate the results for potential to scale.Social implicationsThe R-Archive is a community-centred and driven effort to identify and preserve, under as secure and trusted conditions as possible, digital copies of documents that are of juridical, cultural and personal value to the Rohingya people and also of significance as primary documentary evidence that might be used by international legal institutions in investigating genocide taking place in Burma and by academic researchers studying the history of Burma.Originality/valueThe R-Archive is novel in terms of its technological application (Arweave), the economic concerns of a vulnerable stateless population it is trying to address, and its functional complexity, in that its goal is simultaneously to serve both legal evidentiary and community archive functions. The R-Archive is also an important addition to other notable efforts in the diasporic Rohingya community that have attempted to employ the tools of technology for cultural preservation.
