Developer t4t5 has rebuilt Satoshi's 2009 bitcoin.exe byte for byte. Nobody had previously managed to recreate the published executable from source, because the exact build environment was unknown.
Using AI, he reverse-engineered the build machine from the binary itself — the resulting exe now produces the exact same SHA256 hash as the original 2009 release.
