DIN SPEC 3104:2019
Blockchain-based validation of data; Text in English
This DIN SPEC in accordance with the PAS procedure has been drawn up by a DIN SPEC (PAS)-consortium set up on a temporary basis. This DIN SPEC has been developed and approved by the authors named in the foreword of the DIN SPEC. This DIN SPEC specifies the technical framework and functions of blockchain validation software for blockchain validation processes. In particular, it provides requirements and evaluation criteria for blockchain proof of correctness and blockchain time-stamping functional aspects. The evaluation criteria are given for public proof of work blockchains, as these are the main ones being used in blockchain validation software. The criteria do not specify when blockchain time-stamps are considered good, but instead require the software to provide the users with sufficient information to make a judgment on their own. Other functional aspects of blockchain validation software, in particular the identification of users and the storage of data, as well as topics involving the development of the software itself, such as quality assurance, are not covered by this document. This DIN SPEC is aimed towards blockchain validation software users. A discussion regarding the software of public proof of work blockchain themselves is not part of this specification. This document is applicable to blockchain-based validation in general as well as specific applications, such as: - Proof of physical and intellectual property rights (except form requirements), - Declarations of intent (except written form requirements), - Public registers, - Website and accounting document validation, - Facilitating blockchain-based validation of documents in a multinational environment and - Energy networks and SmartMeter technologies. The certification and notarization of documents is not in scope of this document as these processes are specified by national and European law.
