I am trying to simulate the Bitcoin Blockchain using regtest for research reasons but am having lots of trouble. I have a beowulf cluster that I am trying to run the simulation on. For some specifics I am trying to rapidly send transactions and generate blocks with specified block times. I am using MPI in C++ with GitHub.com/minium/bitcoin-cpp-api to attempt this. Can anyone suggest a better or more simple way of approaching this? How would you go about this?
