bootstrap-node bootstrap-nodes	A node to which a daemon connects to give immediate usability to wallets while syncing

The Basics

The @daemon running on a local @node has to sync with other @remote-nodes. While it is not fully synced, @wallet may still be connected to the local node. Therefore, the @wallet cannot access the @blocks that are not yet synced on the local @node.

To allow the @wallet to be immediately usable, the daemon on the local @node uses a bootstrap node to which the RPC request are proxying to, giving access to the missing @blocks.

Note: the replies from the bootstrap node may be untrustworthy.
