"Unfortunately I am having trouble fully understanding the system. The paper describes key concepts and some data structures, but does not clearly specify the various rules and verifications that the participants in the system would have to follow
In particular I don't understand exactly what verifications P2P nodes perform when they receive new blocks from other nodes, and how they handle transactions that have been broadcast to them. For example, it is mentioned that if a broadcast transaction does not reach all nodes, it is OK, as it will get into the block chain before long. How does this happen - what if the node that creates the "next" block (the first node to find the hashcash collision) did not hear about the transaction, and then a few more blocks get added also by nodes that did not hear about that transaction? Do all the nodes that did hear it keep that transaction around, hoping to incorporate it into a block once they get lucky enough to be the one which finds the next collision?"
