Expand description

Some simple messages The version message

Fields§

§version: u32

The P2P network protocol version

§services: ServiceFlags

A bitmask describing the services supported by this node

§timestamp: i64

The time at which the version message was sent

§receiver: Address

The network address of the peer receiving the message

§sender: Address

The network address of the peer sending the message

§nonce: u64

A random nonce used to detect loops in the network

The nonce can be used to detect situations when a node accidentally connects to itself. Set it to a random value and, in case of incoming connections, compare the value - same values mean self-connection.

If your application uses P2P to only fetch the data and doesn’t listen you may just set it to 0.

§user_agent: String

A string describing the peer’s software

§start_height: i32

The height of the maximum-work blockchain that the peer is aware of

§relay: bool

Whether the receiving peer should relay messages to the sender; used if the sender is bandwidth-limited and would like to support bloom filtering. Defaults to false.
