A central code built into every Terra Station (dapp version) that controls all the connected decentralized nodes (dapp stations), (all nodes synced to the same community authorized code) updated from a central location (authorized coder’(s) ‘ dapp) that updates all nodes only after passing of governing proposals (double layered).
Access to make adjustments should have oversight too (all activity visible ~ in real time) through the terra station dapp connected to all other station dapps (nodes) that are connected through an internet connection (others updated when they connect). Unique identity access to coding manipulation would be granted by government ~ coder info (Terra Station ID) included in the governance proposal.
This would require an access point to the core code in all Terra Stations. The code manipulatable on all Terra Stations. Those with access to manipulate it (through their unique Station dapp) would do so following government direction (seen in live time by all others without that manipulative access) and once update is completed on the node with ‘manipulatable’ access, another government proposal (to verify the manipulation was done correctly) should go up for votes, and if passed ~ the coder is granted another access to send the update to all nodes.
