A method for obtaining a blockchain structure includes providing a first data block and a second data block, wherein a first data processing rule is assigned to first data of the first data block, and a second data processing rule is assigned to second data of the second data block. The first data processing rule is linked to the second data processing rule to obtain a third data processing rule, wherein the first data processing rule is executed before the second data processing rule when the third data processing rule is executed. The second data processing rule is linked to the first data processing rule to obtain a fourth data processing rule. When the fourth data processing rule is executed, the first data processing rule is executed after the second data processing rule. The third data processing rule is stored in the second data block and the fourth data processing rule is stored in the first data block to obtain the blockchain structure.

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

The method includes generating an additional block for expanding a blockchain structure, which includes the data to be stored and is intended to be linked bidirectionally to the last block of the blockchain structure; calculating a first check value of the last block for bidirectionally linking the additional block to the last block of the blockchain structure; calculating a check value of the additional block for bidirectionally linking the additional block to the last block of the blockchain structure; adding the first check value of the last block to the last block and; adding the check value of the additional block to the additional block.
