light node reference for Celestia Mocha testnet

Executable installation and upgrade automation is withheld

The legacy guide pinned obsolete source tags, replaced system Go and removed node directories. Confirm the supported Mocha network, current release and official checksum or signature before installing or upgrading.

Planning requirements

Read-only diagnostics

These checks do not install, initialize, restart, upgrade or delete services or nodes.

STORE="$HOME/.celestia-light-mocha-4"

command -v celestia >/dev/null || { echo "celestia binary is not installed" >&2; exit 1; }

Reversible decommission

This stops and disables the service, then moves the complete node store to a retained timestamped path. Nothing is removed.
