Abstract: A computer implemented method for detecting malicious events occurring with respect to a blockchain data structure comprising: defining a transaction creation profile according to which transactions can be generated and submitted to the blockchain; submitting a transaction to the blockchain, the transaction causing the generation of a profiler data structure in the blockchain including executable code to generate profile transactions to be submitted to the blockchain according to the transaction creation profile; monitoring the blockchain to identify profile transactions; and comparing identified profile transactions with the transaction creation profile to detect a deviation from the transaction creation profile, such detection corresponding to a malicious event occurring with respect to the blockchain.
