Pin argenté is a libp2p transport on working on yggdrasil, Ironwood and go-QUIC.
It allows libp2p nodes to efficiently exchange data on the yggdrasil network.
Note, Pin argenté is NOT part of the yggdrasil IPv6 overlay network. It can route data with yggdrasil's nodes (in both directions), but yggdrasil nodes can't connect to Pin argenté one since we do some custom crypto and packeting (we use QUIC instead of IPv6).
