My understanding is this, that, MultiChain, internally, manages collection of blocks, in the form of "Merkle Tree".
In my chain, "getblockchaininfo" command depicts, "blocks: 81"....i.e. my chain is having "Total Block Count = 81".
Initially, I thought, 81th-block, shall be the leaf in my "Merkle Tree".
but, I was wrong, as, from the output of commands "getblockhash & getblock".....I had seen that 81th-block is actually the root of the Merkle Tree.
How I reached to that conclusion ?
Well, because total confirmations in the output of "getblock" ...was ONLY ONE.
So, the analogy I have build from aforesaid observations is as follows:
Any "New Block", in the MultiChain, shall increase the "Height" of existing blocks, BY ONE.
Am I building correct analogy ?
Following was the output of getblockhash & getblock for the reference:
