user33736: I am doing research on block chain malleability and I want to build my own blockchain prototype / testbed in order to practically see the malleability issues in blockchaining mechanism (like bitcoin). Is there any ideal tool available (esp in Python) which can best serve the purpose.

user12983: You do not need to have private blockchain to investigate malleability issues. You should start with learning ECDSA algorithms and data structures.
Trust me.
