Fulcrum 2.1.1

on GitHub

What's New:

Fulcrum 2.1.1 is a bugfix version of the 2.x series. Most significantly, it fixes a bug when using BTC on the Windows version of Fulcrum, where sometimes you can get spammy messages about exhausted Win32 API handles. (See: #324 ). This issue has now been fixed. It also contains other minor nits and fixups and 1 new JSON-RPC protocol method.

Detailed Summary of Changes (vs v2.1.0)

• Add RPC method: blockchain.address.get_status & blockchain.scripthash.get_status (#316), providing a way to query scripthash status without actually subscribing. Thanks to @mainnet-pat for suggesting this change.
• Minor nit/tweak to BTC::Address toCScript()
• Performance: Add ability of CScript to push byte blobs from std::span
• Internals: Fix isWindows() returning the wrong result on Windows in Common.h
• PeerMgr: Throttle new connections in process() (fixes issue #324)
• On unclean shutdown and restart, lower the number of blocks we undo to 1 (was: 6).
• Fix for compile issue with rocksdb v11 or greater (thus fixing a build issue on latest arch linux).
• Code nits: Moved the code to figure out rocksdb version into Storage/Compat.cpp
• Pulled latest changes from BCHN sources for: bitcoin/token.h, plus some code quality tweaks to bitcoin/token.h.

Pre-compiled Binaries for Linux

I have provided two pre-built binaries for Linux:

• Fulcrum-2.1.1-x86_64-linux.tar.gz, which is compiled on an Ubuntu 18.04 system using Docker.
• Fulcrum-2.1.1-arm64-linux.tar.gz, which is compiled on an Ubuntu 22.04 system (for ARM64 bit) using Docker.

All of the above binaries contain jemalloc, libzmq, libminiupnpc, Qt6Core, Qt6Network (from Qt 6.10.0), 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-2.1.1-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, libminiupnpc, Qt 6.10.10, OpenSSL 3.3.0, and gcc 15.2.0.
  • 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!
