Method for linking a first data block to a second data block, method for checking the integrity of a blockchain structure, device and computer program product

A method for checking the integrity of a block chain structure, comprising:

• obtaining the block chain structure, wherein the block chain structure links a first data block with a second data block, wherein the first data block comprises first data and wherein the second data block comprises second data, wherein a first data processing rule is assigned to the first data and a second data processing rule is assigned to the second data, wherein the second data block comprises a link of the first data processing rule and the second data processing rule to a third data processing rule, wherein the first data block comprises a link of the first data processing rule and the second data processing rule to a fourth data processing rule, wherein the second data processing rule is configured to be executed after the first data processing rule when the third data processing rule is executed, wherein the second data processing rule is configured to be executed before the first data processing rule when the fourth data processing rule is executed;
• assigning a fifth data processing rule to the second data block based on the second data of the second data block and assigning the second data processing rule to the second data;
• executing the fifth data processing rule in a predetermined order with the fourth data processing rule to obtain an execution result;
• and
• confirming the integrity of the block chain structure when the execution result corresponds to a predetermined reference result.

• assigning a further second data processing rule to the second data block based on the second data of the second data block;
• assigning a further first data processing rule to the first data block based on the first data of the first data block;
• obtaining a further third data processing rule by linking the further first data processing rule with the further second data processing rule;
• comparing the third data processing rule with the further third data processing rule;
• and
• confirming the integrity of the block chain structure if the result of the comparison shows that the third data processing rule matches the further third data processing rule.
