This book compiles the proceedings of 6th International Congress on Blockchain and Applications 2024 (BLOCKCHAIN’24), held in Salamanca, Spain, in June 2024. The book includes 31 full papers presented in the main track that were selected among 51 submissions, highlighting theoretical advances and practical implementation of blockchain and distributed ledger technologies (DLTs). In addition, it contains 9 papers from the associated workshops and doctoral consortium that cover topics such as cybersecurity, legal aspects, and climate action.Blockchain and DLTs have revolutionized the scientific community by enabling breakthroughs in secure, decentralized data management, fostering transparency, and collaboration. Researchers are boosting innovation in areas like smart contracts, consensus algorithms, and governance models. In combination with cutting-edge technologies such as AI, metaverse, or quantum computing, blockchain and DLTs are shaping the future of digital trust and innovation.

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.
