    Background: Currently, a node will only rebroadcast a transaction if it is the originating wallet. This is awful for privacy.
PR #16698 reworks the rebroadcast logic to significantly improve privacy.
Overview of changes


Instead of the wallet directly relaying transactions to peers, the wallet will submit unconfirmed txns to the node, and the node will apply logic to trigger txn rebroadcasts.
The node will apply rebroadcast conditions to all transactions.
The wallet will attempt to resubmit unconfirmed transactions to the node on a scheduled timer. This is only useful if the txn is dropped from the local mempool before it gets mined.
The mempool tracks locally submitted transactions (wallet & rpc) to ensure they are succesfully rebroadcast. Success is defined as receiving a GETDATA for the txn.

Debugging Bitcoin Core

This guide is designed to give beginners of C++ development and/or people new
to the bitcoin core code base an overview of the tools available for debugging
issues as well as giving hints where issues may trip you up.

    Network partition resistance

For the Bitcoin network to remain in consensus, the network of nodes must not
be partitioned. So for an individual node to remain in consensus with the network,
it must have at least one connection to that network of peers that share its
consensus rules. This document describes how we attempt to achieve this.
We can't rely on inbound peers to be honest, because they are initiated by
others. It's impossible for us to know, for example, whether all our inbound
peers are controlled by the same adversary.
