This process does not require a unique ARM toolchain since modern compilers are capable of cross-platform compilation, including building on x86-64 and targeting ARM. The task also involves some linker configurations to manage the assembly functions properly. In the context of the Bitcoin core codebase, there are mentions of x86-specific assembly functions within the secp256k1 library, which are mainly about scalar optimizations. Such details might be particularly interesting, as highlighted in a discussion on the Bitcoin Development Mailing List (Bitcoindev). The focus is not necessarily on compiling the entirety of the Bitcoin core but rather on fine-tuning the libbitcoinkernel engine. The inclusion of RISC-V support for the consensus engine's compilation could mark a significant advancement.

On another note, there's an observation that ARM binaries are available for all major operating systems except Windows, despite Apple Silicon being essentially ARM-based. This raises questions about the feasibility of creating ARM binaries for Windows and whether existing methods support Arm64. The Windows build guide suggests Visual Studio as a potential tool that might facilitate ARM support, but the presence of x86-specific assembly functions in the codebase could pose challenges for the build process.
