Unlike shares owned in the public market, shares owned in private companies are purchased during various fund raising rounds (generally called “Series”) and come with a variety of purchase rights and provisions. When shares are sold, transferred, repurchased, or split, it is important that the original share issuance information is transferred to the certificate. By utilizing private blockchain technology, Astrella allows issuers to manage and track the ownership history (or geneology) of each share from the time they are issued until exit. Visualizations showing the change in ownership can, with proper credentials, be shown to either on a browser, on a mobile device or from a printed copy using a QR code.
