Nevertheless, even though in general the transparency of the public blockchain is a desirable feature in the energy domain, the prosumer energy data is sensitive and rather private, thus, a privacy-preserving solution is required. In this paper, we present a decentralized implementation of demand response programs on top of the public blockchain which deals with the privacy of the prosumer\u2019s energy data using zero-knowledge proofs and validates on the blockchain the prosumer\u2019s activity inside the program using smart contracts. Prosumer energy data is kept private, while on the blockchain it is stored a zero-knowledge proof that is generated by the prosumer itself allowing the implementation of functions to validate potential deviations from the request and settle prosumer\u2019s activity. The solution evaluation results are promising in terms of ensuring the privacy of prosumer energy data stored in the public blockchain and detecting potential data inconsistencies.<\/jats:p>","DOI":"10.3390\/s20195678","type":"journal-article","created":{"date-parts":[[2020,10,5]],"date-time":"2020-10-05T14:43:48Z","timestamp":1601909028000},"page":"5678","source":"Crossref","is-referenced-by-count":43,"title":["Blockchain and Demand Response: Zero-Knowledge Proofs for Energy Transactions Privacy"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"http:\/\/orcid.org\/0000-0002-4886-3572","authenticated-orcid":false,"given":"Claudia Daniela","family":"Pop","sequence":"first","affiliation":[{"name":"Computer Science Department, Technical University of Cluj-Napoca, Memorandumului 28, 400114 Cluj-Napoca, Romania"}]},{"given":"Marcel","family":"Antal","sequence":"additional","affiliation":[{"name":"Computer Science Department, Technical University of Cluj-Napoca, Memorandumului 28, 400114 Cluj-Napoca, Romania"}]},{"given":"Tudor","family":"Cioara","sequence":"additional","affiliation":[{"name":"Computer Science Department, Technical University of Cluj-Napoca, Memorandumului 28, 400114 Cluj-Napoca, Romania"}]},{"given":"Ionut","family":"Anghel","sequence":"additional","affiliation":[{"name":"Computer Science Department, Technical University of Cluj-Napoca, Memorandumului 28, 400114 Cluj-Napoca, Romania"}]},{"given":"Ioan","family":"Salomie","sequence":"additional","affiliation":[{"name":"Computer Science Department, Technical University of Cluj-Napoca, Memorandumului 28, 400114 Cluj-Napoca, Romania"}]}],"member":"1968","published-online":{"date-parts":[[2020,10,5]]},"reference":[{"key":"ref_1","unstructured":"(2020, May 15).
