Starlog, Metadata Blockchain based on Substrate. The goal of Starlog is to research and develop an open source solo chain or potential parachain, which stores metadata for the next generation of the world wide web as non-fungible tokens as well as availability data. The metadata will be signed by the uploaders and includes a unique file hash, a price, a timestamp, a license code, a metadata hash (off-chain information about the uploaded file itself) as well as the location of the initial upload or pinning gateway.
