Cobalt Age adds a new Overworld mineral: Cobalt.
The cobalt comes with its own set: Cobalt Ore (Stone and Deepslate), Raw Cobalt, Cobalt Ingot, Cobalt Nugget, Cobalt Block and Raw Cobalt Block.
By that, you may combine a Cobalt Nugget with Redstone, obtaining the Cobalt Dust, the base of a new energy system that behaves similarly to Redstone while providing several unique advantages:
Optimized Modern Signal Engine, eventually toggable in configs, which does not cause even a minimum TPS or FPS change. Fully independent from Redstone signals. Can be waterlogged. Underwater automation and circuitry (consequence of Waterloggability) Prevents water flows from breaking dust networks (consequence of Waterloggability) Other than the Cross and Dot states, which are already in Redstone, it has the Retracted state. Allowin the Cobalt Dust to be smarter than redstone (check the last image in "Cobalt Age Showcase" down here for clarifications) Comes with a set of Cobalt Energy Blocks (CEBs): Cobalt Dust Cobalt Dust Block Cobalt Repeater Cobalt Comparator Cobalt Torch Cobalt Rail Cobalt Relay Cobalt Lamp Converter Comes with a set of Decorative Blocks: Cobalt Block Raw Cobalt Block
As you may guess, the Converter will work as a bridge for the two systems.

Cobalt Block is compatible with the Beacon:

The new beacon GUI, the cobalt ingot has been added in the GUI.

Water does not break the blocks:

A closer look into the retracted state:

## High-Performance Signal Engine
Cobalt wires eventually use a modern optimized signal propagation system (toggable with `/cobaltage on` and `/cobaltage off`) capable of dammatically reduce computation costs compared to vanilla Redstone. The reason are mainly because the new engine:
1. Minimizes the number of times a cobalt wire checks its surroundings to determine its power level.
2. Minimizes the the number of block and shape updates emitted.
3. Minimizes memory allocation using bit masks instead of calling the world states
4. Minimizes cpu calculations saving each network in a virtual ram
5. Skips rendering block updates when signal changes
Unlike alternative optimization approaches, cobalt wires and relays eventually preserve vanilla update order and behaviour, including mechanics that rely on update timing and ordering, such as dupe machines.
Benefits are: No computational cost No TPS change No FPS change Maintains compatibility with all mods which may include more signal absorbers (Consumers) and more signal emitters (Emitters), or even signal modification mods like Alternate Current (which does optimisation to redstone in a similar way Cobalt Age does).
Performance Tests
Scatter Test in a 100 x 100 wire linked web with 20 observer clocks. Cobalt dust does not cause not even a minimum server lag or client FPS drops (10 ms over 50 ms), while redstone dust cause a huge lag and a huge delay of 2. 8 seconds from a tick to another one (130+ ms over 50ms). You can see the delay in the redstone update signals in the shown videos.
## Independent Energy Systems
Cobalt Energy Blocks (CEBs) and Redstone Energy Blocks (REBs) completely operate independently. They emit signals on different channels. You may think the system will break when you try to transfer the a signal through a block which is in the set of the other signal channel (example a redstone torch behind a cobalt dust block). Well, it will not break, as the *signal channels will not inter
