Transports, upgrades, multiplexing and node handling of libp2p.
The main concepts of libp2p-core are:
- A [
PeerId] is a unique global identifier for a node on the network. Each node must have a different [PeerId]. Normally, a [PeerId] is the hash of the public key used to negotiate encryption on the communication channel, thereby guaranteeing that they cannot be spoofed. - The [
Transport] trait defines how to reach a remote node or listen for incoming remote connections. See the [transport] module. - The [
StreamMuxer] trait is implemented on structs that hold a connection to a remote and can subdivide this connection into multiple substreams. See the [muxing] module. - The [
UpgradeInfo], [InboundUpgrade] and [OutboundUpgrade] traits define how to upgrade each individual substream to use a protocol. See theupgrademodule.
