🔲Alloy Constructs - Utility

This page is a deep dive into the following Alloy Construct metadata:

1. Alloy Construct Types

2. Alloy Construct Grade

3. Alloy Construct Rank

4. Alloy Value

Alloy Construct Types

Alloy Constructs will be composed of multiple Alloy Parts that have various Part Types, but will be assigned a new Construct Type when the parts are assembled. This table shows the 8 possible Construct Types and their future application.

Construct Types	Construct Application
Defense	Shields, cloaking, evasive technology, and weapon defense systems
Energy	Power generation and energy storage equipment
Electromechanical	Robotics, manufacturing equipment, electrical systems, cooling systems
Communication	Communication technology, ansible, sensors & navigation
Whoosh	Spacecraft, engines, thrusters, propulsion drives, rovers, vehicle components
Structural	Spacecraft hulls and skeletons, Walkways, Habitats, Warehouses, Ducting, etc
Biocontrol	Life support, agriculture, medical equipment, medicine production
Neotech	Space-age technology including warp machines, antigravity drives, nanotech, transmutation

Construct Grade

Construct Grade summarizes the value and rarity of an Alloy Construct using six categories:

1. Standard

2. Choice

3. Superior

4. Premium

5. Elite

6. Legendary

Alloy Construct NFTs are tagged with their Construct Grade. To assign a Construct Grade, we must calculate the Construct Score, which is the sum of normalized Construct Value and normalized Construct Complexity. These are both in the range 0 - 1 so that Construct Score is in the range 0 - 2.

Normalized Construct Value = (Construct Value - Min Construct Value)/(Max Construct Value - Min Construct Value) Normalized Construct Complexity = (Construct Complexity - Min Construct Complexity)/(Max Construct Complexity - Min Construct Complexity) Construct Score = Normalized Construct Value + Normalized Construct Complexity

In other words, the Construct Grade will be determined by the combined values of the Alloy Value and Part Complexity of the Alloy Parts that were assembled to mint the Alloy Construct.

Construct Grade	Construct Score Range	Estimated Proportion
Legendary	1.95 <= CS	2.5%
Elite	1.85 <= CS < 1.95	5.0%
Premium	1.65 <= CS < 1.85	10.0%
Superior	1.35 <= CS < 1.65	15.0%
Choice	0.8 <= CS < 1.35	27.5%
Standard	CS < 0.8	40.0%

Alloy Construct Rank

Construct Rank is a dynamic value that depends on the circulating Alloy Constructs in the Alloy Space Ecosystem, and must be recalculated for all similarly named constructs when a new Construct is minted. As such, this Rank cannot appear on the NFT, but is only shown in the Alloy Space Marketplace and player Inventory.

For example, if a new Quidifier is minted, all circulating Quidifier Construct Ranks will have to be recalculated.

Construct Rank is calculated as follows:

1. Calculate the Construct Score and Construct Grade as per the above section.

2. Sort all minted constructs of the same name by their decreasing construct score. Suppose there are N of these.

3. Assign the row number to the sorted constructs, such that the construct with the highest Construct Score gets a rank of #1 and that with the lowest receives a rank of #N

4. In the marketplace and inventory for this construct, the following will be displayed on the Alloy Construct cards: "Rank: #x of N <Construct Name>s" (e.g. "Rank: #2 of 20 Quidifiers")

The purpose of this dynamic ranking system is to display the scarcity and relative rank of a given Alloy Construct. This is not necessarily representative of its offer price value in the game, but is important for subjective valuation. This scarcity information could be valuable to a marketplace trader setting prices, or to a collector striving to get the top ranked individual of each Construct. A Construct with a low offer price (due to low constituent part value) could still fetch a high price in the marketplace if there are only a few of those Alloy Constructs in circulation.

Calculating Alloy Value

The Alloy Value of an Alloy Construct is a unit-less quantification of the objective value of a part relative to other parts. It is a function of combined Part Complexity$(c)$, Part Purity$(p(a))$, and Part Age$(a)$. After assembling a construct, you will be given a single opportunity to sell it for the Echo-9 Offer Price, which depends both on Construct Alloy Value ($v$) and the current Alloy Value to Echo-9 Alloy Token exchange rate ($R$). The formula is: Echo-9 Part Offer Price = $R v = R (\gamma (\sum_i^n c_i + p_i(a_i))^\lambda)$ [in $NIOZ] Where $\gamma$ is the Construct Alloy Value multiplier and $\lambda$ is the Construct Alloy Value exponent, composed of $n$ parts indexed by $i$.
