# Request: Get Data (“getdata”)
|
|
|
|
Requests information (generally previously announced via an [inv](/protocol/network/messages/inv) message) from a peer.
|
|
As such, a getdata request carries the same general format as an inventory message and is used to request any items that the node was previously unaware.
|
|
|
|
