The 2nd International Congress on Blockchain and Applications 2020 will be held in L'Aquila from 17th to 19th of June, 2020. This annual congress will reunite blockchain and artificial intelligence (AI) researchers, who will share ideas, projects, lectures, and advances associated with those technologies and their application domains. This meeting will be co-located with that of PAAMS'20. Among the scientific community, blockchain and AI are seen as a promising combination that will transform the production and manufacturing industry, media, finance, insurance, e-government, etc. Nevertheless, there is no consensus with schemes or best practices that would specify how blockchain and AI should be used together.
