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 differentPeerId
. Normally, aPeerId
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 thetransport
module. - The [
StreamMuxer
] trait is implemented on structs that hold a connection to a remote and can subdivide this connection into multiple substreams. See themuxing
module. - The [
UpgradeInfo
], [InboundUpgrade
] and [OutboundUpgrade
] traits define how to upgrade each individual substream to use a protocol. See theupgrade
module.
