Abstract: In a method for electronically documenting license information via the granting of a license and the use of said license in a network of several electronic data processing devices, the license information is added with a new transaction block to a decentralized transaction database and is managed using blockchain technology. When a license is granted to a licensee, a licensor generates new license information with a licensing input, the licensing input contains at least one license identification, and before, during or after use of the license granted by the licensor the licensee generates new license information with a license use input, and the license use input contains at least the license identification of the licensing input and a use identification. The licensing input can contain a license key encrypted with a public key of the licensee, with which the licensor and the licensee can generate and decrypt encrypted information.
