 Bootstrapping new peers to existing peer-to-peer networks is a very well studied problem with several known solutions, each with their own distinct trade-offs. The simplest solution to this problem is simply to package a set of _hardcoded_ bootstrap peers into the packaged P2P node software. This is simple in that each new node has a list of bootstrap peers in the software they're running, but rather fragile given that if the set of bootstrap peers goes offline, then no new nodes will be able to join the network. Due to this fragility, this
 option is usually used as a fallback in case none of the other P2P bootstrapping mechanisms work properly.
