What's new:

This is a minor update to Fulcrum. The most significant feature added is support for BTC's new testnet4, which was recently merged into Core master but is as yet unreleased. BCH and LTC users of Fulcrum don't really have a pressing need to upgrade to this release, but are welcome to do so to take advantage of the minor performance fix contained in this release.

Summary of changes:

  • Added BTC testnet4 support (auto-detected) #255. Requires a bitcoin core bitcoind built to support this new chain.
    • There are currently 2 active servers, one Fulcrum, the other ElectrumX that serve blockchain data for testnet4.
  • Slight performance improvement to the UTXO Cache pre-fetcher mechanism
  • Various code quality fixes and nits

Pre-compiled binaries for Linux

I have provided two pre-built binaries for Linux:

  • Fulcrum-1.11.1-x86_64-linux.tar.gz, which is compiled on an Ubuntu 18.04 system using Docker.
  • Fulcrum-1.11.1-arm64-linux.tar.gz, which is compiled on an Ubuntu 20.04 system (for ARM64 bit) using Docker.

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

Pre-compiled binaries for Windows

  • Fulcrum-1.11.1-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 5.15.13, OpenSSL 3.3.0, and gcc 13.2.0.
    • 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!
