What's new:

Added official Reusable Payment Address (RPA) support. A few new RPCs are offered for servers that have it enabled (default on for BCH only, off for other coins). Also fixed a few minor esoteric bugs.

Summary of changes:

  • Added RPA support (#234 ). This work was community-funded. Thanks to all the contributors to my flipstarter that helped pay for this work.
    • Added a new index, rpa, which is currently only ~42M on mainnet. It starts indexing from block 825000 on mainnet (can be controlled with rpa_start_height= conf file option).
    • RPA is only on-by-default for BCH, off for all other coins. Can be manually enabled/disabled with --rpa or rpa=1 from conf file.
    • A few new RPCs are offered to clients if the index is enabled.
    • Bumped Electrum Cash protocol version to 1.5.3
  • Bugfix: Deal with esoteric 0-input and 0-output txns better (even though they can't happen due to consensus, there was a uint wraparound issue if they do happen to be encountered in some esoteric environments). Fixes #235.
  • Bugfix: In rare circumstances, if the "Download Blocks Task" is interrupted / gets an error, one of the 3 BitcoinD client threads may go out to lunch and never become usable again to do work. Symptoms would include it spamming "Reconnecting ..." messages to the log every 5 seconds. This has been corrected.
  • Lots of code refactoring and code fixups.

Pre-compiled binaries for Linux

I have provided two pre-built binaries for Linux:

  • Fulcrum-1.10.0-x86_64-linux.tar.gz, which is compiled on an Ubuntu 18.04 system using Docker.
  • Fulcrum-1.10.0-arm64-linux.tar.gz, which is compiled on an Ubuntu 20.04 system (for ARM64 bit) using Docker.
  • Fulcrum-1.10.0-x86_64-linux-ub16.tar.gz, which is compiled on a stock Ubuntu 16.04 system (using Docker) but with g++ 8.1.0 installed from this ppa source: ppa:jonathonf/gcc-8 & ppa:jonathonf/gcc

All 3 of the above binaries contain jemalloc, libzmq, Qt5Core, Qt5Network (from Qt 5.15.6), and OpenSSL 1.1.1 statically linked. They still require libz2, libstd++, and the right libc version as dynamic libs on your system (but those are usually present if you are on a recent system).

If the first regular -linux binary fails, try the second one (-linux-ub16), which should work on older systems, hopefully.

Pre-compiled binaries for Windows

  • Fulcrum-1.10.0-win64.zip - Pre-built, statically linked Windows version.
    • It should "just work" on any Windows 10 or above 64-bit system.
    • Includes is a statically-linked Fulcrum.exe, built with jemalloc, libzmq, Qt 5.15.2, OpenSSL 3.0.1, and gcc 11.2.0.
    • Additionally, FulcrumAdmin.exe is included which is the python script, but made into a onefile .exe using PyInstaller.
      • NOTE Windows virus scanners have been known to erroneously identify FulcrumAdmin.exe as containing a virus. This is because many heuristic scanners dislike the use of PyInstaller onefile .exe's. See: #203. Please ignore this -- we contain no viruses! Also please complain to your virus software vendor about this.

See the .asc file for signatures; I signed the sha256 hashes of all the release binaries. My gpg public key can be obtained here: https://github.com/Electron-Cash/keys-n-hashes/blob/master/pubkeys/calinkey.txt

Binary builds for macOS coming soon -- Until then you can always build from source!
