Peer discovery via a list of bootstrap peers
npm install @libp2p/bootstrap
> Peer discovery via a list of bootstrap peers
The configured bootstrap peers will be discovered after the configured timeout. This will ensure there are some peers in the peer store for the node to use to discover other peers.
They will be tagged with a tag with the name 'bootstrap' tag, the value 50 and it will expire after two minutes which means the nodes connections may be closed if the maximum number of connections is reached.
Clients that need constant connections to bootstrap nodes (e.g. browsers) can set the TTL to Infinity.
