This article describes the operations<br /> that deal with this exchange of transactions.<br /> <br /> Transactions are exchanged only if they are standard and [[Invalid block|valid]].<br /> <br /> == Wallet Send ==<br /> <br /> The client periodically calls SendMessages() (in main.cpp) which calls<br /> ResendWalletTransactions to send transactions generated locally.<br /> This routine looks to see if there has been a new block since last time,<br /> and if so, and the local transaction are still not in a block,<br /> then the transactions are sent to all nodes.<br /> This is done only about every 30 minutes.<br /> <br /> Transactions are only rebroadcast if they have a timestamp at least<br /> 5 minutes older than the last block was received. They are sorted<br /> and sent oldest first.<br /> <br /> == Periodic Advertisement ==<br /> <br /> The client periodically calls SendMessages() (in main.cpp) which<br /> determines if a message should be sent to a remote node.<br /> For each message processing iteration, one node is chosen as the<br /> &quot;trickle node&quot;. This node is the only one chosen to receive<br /> an &quot;addr&quot; message, if appropriate.<br /> <br /> In the section for inventory, the client sends 1/4 of the transaction<br /> inventory, determined randomly, UNLESS they are the trickle node,<br /> in which case they receive ALL transactions. Yes, that seems reversed,<br /> but it is what it is. If the node is to receive 1/4 (not all), then the<br /> code also avoids sending any transactions that came from the local<br /> wallet. The comments indicate this is intended to increase privacy.<br /> <br /> == Relay ==<br /> <br /> When the client receives a transaction via a &quot;tx&quot; messages,<br /> it calls RelayMessage, which calls RelayInventory, which queues the<br /> inventory to be sent to all other nodes.<br /> <br /> ==See Also==<br /> [[Transaction_broadcasting | Transaction broadcasting]]<br /> <br /> ==Footnotes==<br /> <br /> ==Source==<br /> <br /> [http://bitcoin.it/ http://bitcoin.it/]<br /> <br /> [[Category:Technology]]<br /> [[Category:Manuals]]</div>
