A method for building a blockchain

A computer implemented method for generating a hash value, the method comprising the following steps:

• i) providing a first digital RGB image having first RGB colors of a physical object;
• ii) combining first transaction data and the first digital RGB image, thereby generating a second RGB image having second RGB colors;
• iii) converting color values of the second RGB image from RGB color space to a secondary color space having at least four primary colors and determining a number of respectively colored pixels for each primary color of the secondary color space;
• iv) generating the hash value by converting the determined number of respectively colored pixels for each primary color of the secondary color space to hexadecimal numerals.

A method for transferring crypto currency, wherein each transaction of a crypto currency unit is done by performing the following steps:

• Generating a digital RGB image having RGB colors by scanning a physical object;
• Combining first transaction data and the digital RGB image, thereby generating an intermediate RGB image;
• Combining identity information and the intermediate RGB image, thereby generating an authentication image having further RGB colors;
• Converting color values of the authentication image from RGB color space to a secondary color space having at least four primary colors and determining a number of respectively colored pixels for each primary color of the secondary color space;
• Generating a one-time verification number by converting the determined number of respectively colored pixels for each primary color of the secondary color space to hexadecimal numerals.
