Abstract 

Block­chains became a game changer in the distri­buted storage area due to their ability to mimic the func­tio­ning of a clas­sical tradi­tional ledger such as trans­pa­rency and falsi­fi­ca­ti­on-­proof in an untrusted envi­ron­ment. However, block­chain inte­gra­tion in indus­trial appli­ca­tions strongly depends on the formal guaran­ties of the quality of services provided, espe­cially in terms of consis­tency. In this presen­ta­tion we forma­lize the block­chain as a compo­si­tion of abstract data types which helps us to define a hier­archy of consis­tency criteria that formally charac­te­rises diffe­rent typo­lo­gies of block­chains. More­over, we present some results on imple­men­ta­bi­lity and a mapping of repre­sen­ta­tive exis­ting block­chains from both academia and industry against the defined consis­tency criteria.
