Nice start. Another dumb question: how do individual transactions get to the miners for addition to the blockchain? Is there some P2P-type auto discovery going on? A central server shouting out miner IPs?

There's an article on that here: https://en.bitcoin.it/wiki/Satoshi_Client_Node_Discovery

TL;DR: The peer discovery process is bootstrapped using a few domain names hard coded in the client. https://github.com/bitcoin/bitcoin/blob/master/src/chainpara...

Thanks. Is there anything on the protocol for passing messages around once you've found some peers?

Geez. That seems...vulnerable.
