This book constitutes the refereed proceedings of the 7th International Congress on Blockchain and Applications 2025, BLOCKCHAIN’25, held at the University of Lille (France) from June 25 to 27, 2025. Among the scientific community, the advance in next-generation blockchain and distributed ledger technologies (DLT) is seen as a promising combination that will transform the production and manufacturing industry, media, finance, insurance, e-government, agriculture, energy, or even medicine. Besides, the combination of DLT with other cutting-edge disruptive technologies (AI, metaverse, quantum computing) will open a multitude of amazing opportunities that entail an interesting challenge of research at the same time. The book includes 13 full papers presented in the main track that were carefully reviewed and selected from over 20 submissions. Additionally, it contains 20 papers from the associated workshops and doctoral consortium. These contributions present the latest advances in blockchain and artificial intelligence, as well as their application domains. They explore innovative ideas, frameworks, guidelines, theories, models, technologies, and tools, while also identifying critical issues and challenges that researchers and practitioners must address in future research.
