Maintaining register of shareholders with the use of blockchain

The article deals with use of hash technology and blockchain technology for the purpose of running register of shareholders in private companies in Poland. Different applications for these technologies are considered. Firstly, publication of hash of each subsequent version of the register of shareholders, what would serve to ensure that a hashed version was indeed an original of the register of shareholders at a given moment in time. Secondly, publication of hash together with publication of each subsequent version of the register of shareholders. That would serve the purpose of making the current version of the register of shareholders widely available, while hash would allow to ascertain that the published version is indeed the original one and no error has been made while publishing it. That would be useful in particular if the register of shareholders could not be otherwise accessed on distance. Thirdly, hashing of the current version of the register of shareholders together with the previous hash to create a blockchain. That would allow to ensure the sequence between different versions of the register of shareholders, preventing omission of any version or retroactive changes to the register of shareholders.
