A very good day to you Sir,

I hope you are doing Great Sir,


I would like to know how many Dis-Similar Bitcoin Networks are there that possesses the following specifications -

      Besides Bitcoin Network.Mainnet - Is there another Bitcoin Network ( EG Network X ) that is separate from the Bitcoin Mainnet Network
      But it is Fully Compatible with Bitcoin Network.Mainnet - And it is able to interface to the Bitcoin Mainnet and can use Transaction ID's of the Bitcoin
      Mainnet ?

Meaning you have 1) The Main Bitcoin Network.Mainnet and 2) The Separate Bitcoin Network.Network-X

Network.Network-X is attached to the Bitcoin Network.Mainnet through a link or tether

Network.Network-X has its own Transaction IDs

But it can use Transaction IDs from Network.Mainnet

Network.Network-X process Network.Mainnet's Transactions and processes just as it is able to process its own Transactions and processes

Network.Network-X can also function on its own as a stand alone Bitcoin Network

Does such a Bitcoin Network Connection Topology Exist with Bitcoin Networks today ?

Is this the case when you sum up all the various other Different Bitcoins together ?

Can some kind soul please advice on this ?

Hope to hear from you soon.

Thank you very much for your time and kind help.

Kind Regards as Always.
