“Lastsend” and “Pilecv” fields understanding Bitcoin in RPC
The RPC GetPeerfo request is a fundamental interface provided by Bitcoin Core software for peer -to -peer connected to local nodes. Among the different fields, two are distinguished: “Lastsend” and “Pasecv”. These fields seem to describe a kind of horoding or horoding, but what do they really represent? In this article, we break down the importance of these fields and explore their effects on transmitting P2P messages.
What does “hard” mean?
The “LastSend” field should include Unix (UTC) wishes during which Vertainen sent the store for the last time. This means that if you check the local node with this method, “will take” to give you horodiving when a similar event is interested.
Illustrates this concept more:
Imagine you are on the P2P network and send a new block to someone else (called “peer review”). Once the local node has added the block to the chain, you can check it by using GetPeerfo" with the following settings:
Bash
GetPeerfo Peerraddress 1234567890ABCDEF, Lastsend = 1643723401, Lastrecv = 1643723402
'
Here, "Lastsend" is set to 1643723401 (in a few seconds in January 1, 1970, 00:00 UTC), when peer review A., 1, 1970, UTC), which has been the current horoditive.
What does "PASECV" mean?
"The Lastrecv field should include the time of the Unix period when the peer received the data for the last time. This means that if you check the local node with this method,” PASECV “will give you horoding when the local node has sent or received similar information.
Saying things in another way: “Lastsend” shows you what happened on the other side (event), while “PASECV” shows you what happened on your side (local node sends / receives information).
Here’s an example:
`Bash
GetPeerfo peerraddress 1234567890ABCDEF, Lastsend = 1643723401, Lastrecv = 1643723412
'
In this case, "lasting" is defined when the peer -to -peer network has practiced their event. At the same time, the 'PaseCV' is defined in the current horodal (1643723412), which shows that the local node received information from the peer at the time.
Effects on P2P messages transfer
When you use RPCGetPereinfo” with these fields, you can make conscious decisions about the event or information has been sent and received. For example::
- If the “ lasts’ is not zero and that “PASECV” is zero, this indicates that your local node has sent information to peer users (after the last shipment).
- If these two “durable” and “Lastrecv” are zero, this suggests that many peers have changed information with you recently.
- If one or another field is zero, this may indicate that there has been a certain type of error or loss during the shipment.
In summary, the Bitcoin RPC’s “LastSend” and “Lastrecv” fields provide a means for the transfer of P2P messages by checking when each peer network has sent and received information. These values provide valuable information about the operation of the network’s local node, which will help you clarify strategies to manage incoming messages and events.
