U.S. PATENT 9,807,106

British Telecommunications 

1. A computer implemented method for detecting malicious attacks presenting a threat to a blockchain associated with a blockchain data structure of a computing device comprising: defining by the computing device 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 by the computing device the blockchain to identify profile transactions based on profile transactions submitted by the profile data structure generated in the blockchain; 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 attack occurring with respect to the blockchain.
