Pull request description:

  Add a new wallet flag called `avoid_reuse` which, when enabled, will keep track of when a specific destination has been spent from, and will actively "blacklist" any new UTXOs which send to an already-spent-from destination.

  This improves privacy, as a payer could otherwise begin tracking a payee's wallet by regularly peppering a known UTXO with dust outputs, which would then be scooped up and used in payments by the payee, allowing the payer to map out (1) the inputs owned by the payee and (2) the destinations to which the payee is making payments.

  This replaces #10386 and together with the (now merged) #12257 it addresses #10065 in full. The concerns raised in https://github.com/bitcoin/bitcoin/pull/10386#issuecomment-302361381 are also addressed due to #12257.

  ~~Note: this builds on top of #15780.~~ (merged)

Bitcoin Core

Setup

Bitcoin Core is the original Bitcoin client and it builds the backbone of the network. It downloads and, by default, stores the entire history of Bitcoin transactions, which requires a few hundred gigabytes of disk space. Depending on the speed of your computer and network connection, the synchronization process can take anywhere from a few hours to a day or more.

To download Bitcoin Core, visit bitcoincore.org.

Running

The following are some helpful notes on how to run Bitcoin Core on your native platform.

Unix

Unpack the files into a directory and run:

  • bin/bitcoin-qt (GUI) or
  • bin/bitcoind (headless)

Windows

Unpack the files into a directory, and then run bitcoin-qt.exe.

macOS

Drag Bitcoin Core to your applications folder, and then run Bitcoin Core.
