How is a transaction broadcasted?
How is a transaction broadcasted? Let's say UserA uses electrum, connected to ServerB, and hits the "Send" button to do a transaction. What happens? The transaction is sent to ServerB only or The transaction is sent from UserA to ServerB but also to 2 (or 10 or 100?) other servers (UserA's electrum has a list of 100 servers to connect, one after another, when he does a transaction) or The transaction is sent from UserA to ServerB only, but ServerB broadcasts it immediately to 2 (or 10 or 100?) other servers Especially if ServerB is late of 1 or 2 blocks from the rest of the network, what happens? Is the transaction lost? Broadcasted anyway? Where are these rules specified in the official implementation? http://ift.tt/2zD7nXF
