Abstract: A general purpose blockchain (GPB) providing the capability of native arbitrary computation and storage of any type of digital object with distributed verification technology (DVT) implementation that not only allows scalable arbitrary computational verification of digital objects, but also is agnostic as to the types of object. The GPB platform comprises an interface for interacting with arbitrary objects (“GPB arbitrary objects”). The interface transforms unstructured data into structured, extensible data without loss of fidelity of the underlying data. This is accomplished through a transformation function, which takes as input any arbitrary form of data and provides as output a structured data object upon which cryptographic and other operations necessary to the functions of DVTs can be performed collectively by a plurality of GPB blockchains. One proposed method of creating this structured output uses open-standard, extensible markup language (XML) data.
