Answering the question what is Libre. Libre - an ecosystem that includes the economic, social, political and cultural components (4 areas of human life by Marx). We mainly talk about the economic sphere (about production) and about the use of new technologies. In particular, about the technology of blockchain, as a very good tool for accounting for various parameters and relationships. For example, debentures, promissory notes, options, forward contracts, sales contracts, rights of claim, ownership rights, shares, bonds, etc.
