Abstract
A computer-implemented method for proof-of-work for generating and validating a block of a blockchain using at least one printing device is disclosed. The printing device is configured for generating at least one digital image depending on a printer control setting. The method comprises the following steps: The method comprises repeating steps ii) () to iv) () until the colored pixels of the mining digital image () and the task digital image () are found to be identical. In each case in step ii) () a different mining printer control setting () is selected. The mining printer control setting () for which the mining digital image () and the task digital image () are found to be identical, at least within tolerances, is used as the proof-of-work for generating and validating the block of the blockchain.
