Let me try.

1) Is LayerZero compatible with decentralized blockchain networks such as Bitcoin? What are prerequisites for compatibility of LayerZero with existing or future blockchain networks?

2) > LayerZero is a communication protocol

Who is supposed to use this protocol? Could you list all groups of participants based on their role? What data they should poses in order to be able to play their role in the network?

3) > Its core function is to ensure "valid delivery." This means the receiving chain correctly matches and verifies transactions from the sender chain, eliminating the need for middlemen.

What it means to "verify the transaction"? What verification steps can LayerZero support and what steps it can't support?

4) > The protocol implements generic messaging that provides trustless valid delivery of arbitrary data.

What means "trustless valid delivery of arbitrary data"?
