To read more of this article please go here .   Government Services In principle, blockchain technologies could be used for providing government services that involve the overall handling and management of public documents which, at least in many developing countries, people have a hard time obtaining. More generally, blockchains could be used to support the overall provision of most public goods to citizens and stakeholders, especially those that demand personal interaction and require individual identification. An implicit link between blockchain technology and e-government does exist, and it is now being explored by a selected group of blockchain startups. Procivis , a Swiss startup, will be soon launching a blockchain-based app store delivering selected government services to the public. It will a
