re-requisites -> pre- ?

I skimmed it and nothing jumped out at me. I understand public key crypto.

Your blog post made me think an explanation of bitcoin mining and transfer would occur. It never did. There was this:

What role do public key signatures play in Bitcoin? They are used to prove to the network that the owner of address A1 (A1 also functioning as a public key!) really did authorize the transfer of certain coins to the next address. Other nodes in the network, in turn, are able to easily verify that the owner of A1 signed off on the transfer by checking that the mathematical relationship I mentioned above holds among the A1 public key, the message indicating the transfer, and the signature on the transfer. And if this relationship doesn't hold, the other nodes (per the Bitcoin protocol) ignore the purported transfer, acting like it didn't exist, and refuse to tell other nodes about it.

... which isn't a very complete. The only thing I learned (I know nothing about Bitcoin mining or transaction protocols) is that apparently lots of nodes end up knowing about every transaction (paying attention only to transactions moving a particular coin that are signed by its last known owner).

So, I gather your explanation of Bitcoin is yet to be written.
