Magnet Link Downloading

A magnet link (Magnet URI scheme) is a computer program that retrieves information and downloads documents in a peer-to-peer network. Unlike Uniform Resource Locators (URLs), which are linked based on “location”, magnet links are based on metadata (metadata) file content and belong to Uniform Resource Names (URNs). That is to say, the magnet link is not based on the IP address or locator of the document, but in the distributed database, through the hash function value to identify, search and download the document. It is especially suitable for peer-to-peer networks without a central server because it does not rely on an active host to download documents.
