Grin

Grin is open-source software for Linux that provides access to the Grin digital currency project. It is listed in MirrorNest’s Business category and is suited to Linux users who need the project’s node or wallet applications. Grin is designed as a privacy-preserving currency based on the Mimblewimble protocol, with no public transaction amounts or addresses.

The Snap includes the grin blockchain node, which can be started with default settings by running grin in a terminal. It also includes grin.wallet for creating an account and sending or receiving transactions. Running grin.wallet help displays the wallet’s available commands. Mimblewimble allows transactions to be aggregated for more efficient storage and permits past transaction data to be removed without compromising security.

During a refresh, Grin can report an error such as a failure to create a logfile because of insufficient permission. This can happen when configuration paths refer to a version-specific Snap directory instead of the current installation path. The paths can be corrected with sed -i 's/grin\/[0-9]\/.grin/grin\/current\/.grin/g' ~/snap/grin/current/.grin/main/grin-*.toml. Removing and reinstalling the Grin Snap is another option, but it requires the software to synchronize again. Use of Grin through Snap may reduce privacy because IP addresses and usage patterns may be tracked.

MirrorNest mirrors the official Grin build directly onto its own storage and scans it for malware before publishing it. This gives Linux users a catalog-based way to obtain the build while retaining its Linux platform and open-source classification. Its node and wallet functions explain its placement in the Business category for users working with the Grin project’s currency tools.
