Method for tamper-proof storage of information in respect of object-related measures, wherein the measures relating to the object are contained as transactions (T 11 , ..., T 1N1 , T 21 , ... T 2N2 , ..., T M1 , ...T MNM ) in transaction blocks (TB 1 , ..., TB M ) that are linked together in a transaction blockchain, TBK, of the object , said transaction blockchain being stored in an object data memory assigned to the object , wherein at least one transaction (T 11 , ..., T 1N1 , T 21 , ... T 2N2 , ..., T M1 , ...T MNM ) is captured (S51), each transaction (T 11 , ..., T 1N1 , T 21 , ... T 2N2 , ..., T M1 , ...T MNM ) contains a validation program code, VPC, wherein the VPC defines rules that specify which transactions are admissible and wherein each transaction block (TB 1 , ..., TB M ) comprises at least one transaction (T 11 , ..., T 1N1 , T 21 , ... T 2N2 , ..., T M1 , ...T MNM ) that specifies a measure undertaken on the object or a measure undertaken by the object itself, wherein an additional transaction block (TB 1 , ..., TB M-1 ), following its successful validation, is linked to the last transaction block (TB M ) situated at the end of the transaction blockchain, TBK, of the object , wherein the transaction blockchain, TBK, of an object is read from the object data memory of the object and the transactions (T 11 , ..., T 1N1 , T 21 , ... T 2N2 , ..., T M1 , ...T MNM ) contained in the transaction blocks (TB 1 , ..., TB M ) of the transaction blockchain, TBK, are verified as admissible on the basis of their respective validation program code, VPC, and wherein a transaction (T 11 , ..., T 1N1 , T 21 , ... T 2N2 , ..., T M1 , ...T MNM ) verified as admissible on the basis of its validation program code, VPC, at the time of writing to the object data memory of the object and/or at the time of reading from the object data memory of the object confirms the measure being undertaken on the object . wherein the measures relating to the object are contained as transactions (T 11 , ..., T 1N1 , T 21 , ... T 2N2 , ..., T M1 , ...T MNM ) in transaction blocks (TB 1 , ..., TB M ) that are linked together in a transaction blockchain, TBK, of the object , said transaction blockchain being stored in an object data memory assigned to the object , wherein at least one transaction (T 11 , ..., T 1N1 , T 21 , ... T 2N2 , ..., T M1 , ...T MNM ) is captured (S51), each transaction (T 11 , ..., T 1N1 , T 21 , ...

T 2N2 , ..., T M1 , ...T MNM ) contained in the transaction blocks (TB 1 , ..., TB M ) of the transaction blockchain, TBK, are verified as admissible on the basis of their respective validation program code, VPC, and wherein a transaction (T 11 , ..., T 1N1 , T 21 , ... T 2N2 , ..., T M1 , ...T MNM ) verified as admissible on the basis of its validation program code, VPC, at the time of writing to the object data memory of the object and/or at the time of reading from the object data memory of the object confirms the measure being undertaken on the object . <EOS>
