Alerts are cryptographically signed by a public key. The corresponding private key is held by a few selected members of the core development team. The digital signature ensures that fake alerts will not be propagated on the network.

Each node receiving this alert message will verify it, check for expiration, and propagate it to all its peers, thus ensuring rapid propagation across the entire network. In addition to propagating the alert, each node may implement a user interface function to present the alert to the user.

((("Bitcoin Core client","alerts, configuring")))In the Bitcoin Core client, the alert is configured with the command-line option +-alertnotify+, which specifies a command to run when an alert is received. The alert message is passed as a parameter to the +alertnotify+ command. Most commonly, the +alertnotify+ command is set to generate an email message to the administrator of the node, containing the alert message. The alert is also displayed as a pop-up dialog in the graphical user interface (bitcoin-Qt) if it is running.
Other implementations of the bitcoin protocol may handle the alert in different ways. ((("mining","hardware, alerts and")))Many hardware-embedded bitcoin mining systems do not implement the alert message function because they have no user interface. It is strongly recommended that miners running such mining systems subscribe to alerts via a mining pool operator or by running a lightweight node just for alert purposes.(((range="endofrange", startref="ix_ch06-asciidoc0")))
