While "del-fact.7z" lacks its own dedicated documentation, the evidence strongly suggests it is a , likely a deletion-focused variant of the standard docker-fact.7z test contract. It contains a Go smart contract intended for deployment on the ChainMaker blockchain platform.
# Install p7zip if not already installed sudo apt install p7zip-full # Debian/Ubuntu sudo dnf install p7zip # Fedora/RHEL
If you have recently run data recovery software or a system optimization tool, the file might be an automated artifact.
