Next to common plagiarism, this is another reason why proving one's authorship becomes increasingly important. One way to support this proof is to document the work process in a certified artifact. Blockchain technology lends itself to this by generation of a data structure that is intrinsically unchangeable and via strong asymmetric cryptographic algorithms tied to the creator. In this paper, we present a concept to record and validate one's creative work. To demonstrate its feasibility, we provide a proof of concept implementation that documents and encodes a sculpting process conducted in the open-source modeling software Blender.enBlenderBlockchainCertificatePrototypeconference paper
