The main object of interstellar trade is the emerging star sector.

These but complete civilization system components of the star region require a long time to carry out infrastructure projects, from the exploitation of star resources to the establishment of a space industry on the surface, it is a long process from scratch.

However, as long as the infrastructure of the star sector is completed, the emerging star sector can basically maintain its own civilized operation and ensure the development of the star sector society.

So depending on whether an emerging new area has a complete industrial system, the goods of interstellar transportation are divided into two stages.

The first stage is the follow-up support that arrives after the initial construction of the colony.

Such a transport fleet can also be called a colonial fleet, such a fleet contains a large number of people, industrial equipment, and a life support system, all the way to the colonized planet to establish an ecological region, and has a complete industrial system and sufficient population development.

Interestingly, the former Federation human civilization was plagued by overpopulation when it was still on its home planet.

And in the interstellar age, the population problem is also troubled, this time because of the low population.

Even if it is tens of billions, hundreds of billions of human civilization population, facing the vast galaxy is just a drop in the water, and any star region can easily swallow these populations.

There are countless star systems waiting to be developed in the galaxy, and the actual citizen-inhabited planets owned by the four major civilizations of the entire Federation are just a drop in the ocean, and most of the planets in the star regions controlled by them are just automated collection factories to collect resources.

The inadequacy of the population and the high cost of interstellar travel doomed the low mobility of the interstellar population.

Although human civilization has a history of thousands of years, it has entered the interstellar era for less than a thousand years, and so far, there are only a few star regions that are close to the home star region and several bordering star regions that have been established with the other three federation civilizations.

As for the three major war zones of the Silver Heart, a large number of military bases and spacedocks were added after the outbreak of the war, and if you want to say that the citizens live in it, it is basically a barren area, and the star area from the home star area to the Silver Heart is basically a no-man's land in addition to a large number of navigation node planets.

In general, the galaxy is too big to be developed, and if the first stage of the star sector is a primary star sector, then it needs a large amount of material support from the intermediate development star sector or the advanced mature star sector with a complete industrial system.

The intermediate development star sector in the second stage already has a complete scientific and technological industrial system, and can achieve self-sufficiency in basic materials and materials, and the star sector can develop sustainably on its own.

Therefore, the required cargo attributes for interstellar transportation in the relay star sector are also determined.

First of all, there is a huge amount of data in various scientific research fields, because interstellar communication is blocked by a moat in space measured in light years, and warp speed navigation itself can be regarded as an active means of communication beyond the speed of light.

As for the passive over-the-distance communication technology, it cannot be said that there is no in the federal technology tree, but the efficiency of inter-satellite communication is terrible compared to the low warp speed of the starship, and the channel stability and data bandwidth are incomparable.

The second is the advanced scientific and technological products from the advanced mature star region, including the matrix host, antimatter furnace, warp speed engine and other high-tech integrated products, etc., these high-tech creations require deep technology and talent accumulation, which is also a hard defect of the intermediate star region.

The accumulation of technology can be quickly compensated, and it is enough to establish a production plant system again, but this only has production capacity. It is necessary to go through the process of talent accumulation in order to have similar scientific and technological research and development capabilities belonging to its own star region.

Before the R&D capability is formed, such advanced high-tech products need to be continuously supplied by the advanced star sector through interstellar transportation.

Just like Su Zhao rushed from the Arcturus region to the developed South Gate Second Star Zone, he rushed to the South Gate Second Star Zone to exchange for the Sirius with the resources raised by the Arcturus Region, precisely because the starship production capacity of the Arcturus Region was not enough to produce and manufacture the latest generation of Sirius starships.

The third part, biological tissue transportation, is the most important supporting part of many industries led by the pharmaceutical and biological industries in the major star regions.

Compared to the extravagant behavior of the Archons of the Arcturus Archon raising sheep for ornamental purposes, the pharmaceutical and biological industries, which have a great demand for biological tissues, are the big customers of this business.

These tissues are used in biochemistry-related fields, such as human life-sustaining, prosthetic limb modification, disease treatment, drug production, high-energy nutrient solution production, ecological maintenance, etc., involving all aspects of the life of the citizens of the colonial sector and the development of the sector.

In the case of dormancy-related liquids and medicines, if you want to establish a complete production system, you must first obtain the biological tissue mother and related technical information from the star sector that owns this industry, and even build a corresponding breeding environment for some living organisms to multi-generational reproduction.

It will take a lot of time to go into mass production until a specific biological secretory tissue of a specified size is available, and then it will take a lot of time to scale up to the point where supply and demand are balanced.

The last part is naturally the transportation of antimatter raw materials, which are essential for interstellar travel.

Antimatter raw materials are mainly obtained by mining antimatter fountains distributed in the Milky Way, and the scientific and technological explanations of the formation of these antimatter fountains are very complex, in simple terms, the mass distorts space, and the complex energy channels gathered by mass stress points and the interaction of nearby high-mass density stars form antimatter fountains.

Macroscopically speaking, antimatter fountains can be found near black hole objects of a certain scale, and suitable star regions outside the safe distance of these black hole objects are naturally near the water, which is the object of priority colonization and development of the Federation.

The Silver Heart Antimatter Fountain is naturally the largest antimatter resource point in the entire Milky Way, and the only fountain in the center of the Greater Magellanic Nebula is more distant is the same status.

The interstellar voyage of the entire federation relies on the antimatter collected and transported by these resource points, so that the antimatter can even serve as part of the currency function in the interstellar space, directly exchanging resource points.

This is the main cargo characteristics of interstellar transportation, and where there is transportation, there is naturally trade, but the financial system in the interstellar era, catalyzed by the long distance between the star regions, has a completely different performance from the traditional financial industry.

The first point is the settlement of off-site settlements between star zones.

Hundreds of thousands of light-years of distance limitations, it is impossible for the Federation to establish a unified financial system, each star system, and even each planet such as star regions will have its own financial system, the basic exchange equivalents are even more indefinable, Arcturus gold and rock prices such examples abound, and the difference in resource abundance leads to the inability to define interstellar equivalence.

However, ordinary electronic credit money cannot be settled in real time, and it is even more difficult to move an inch after it is beyond the scope of the stars.

The electronic currency in the form of the result of mathematical calculation through the distributed network can be used due to the difference in the size of the network between star regions, even if the output of the same algorithm is different, coupled with the difference in the market price of their respective regions, it can be used, but it is extremely troublesome and the value fluctuates greatly.

So, how to determine the equivalence between the stars, it seems difficult.

Yes, it looks difficult, but it's actually very simple, and it's a kind of interstellar cargo in itself.

That's it - starships.

A starship that travels between the stars can itself be a kind of interstellar equivalent.

The models of starships are vast, but as long as they are starships of the same level and size, they can be regarded as of the same value except for battleships.

The transportation of oversized cargo is generally directly undertaken by the federal government, and the resource index level is basically above the level of large starships, or military personnel such as warships.

Such interstellar transportation has nothing to do with trade, so there is no need for financial settlement procedures at all.

Therefore, resource points are basically equivalent to small and medium-sized starships, and the specific process is as follows.

In the financial system of the Star Zone, conquering the Star Sector with sufficient monetary solvency and exchanging resource points at the market price of the starship proves that Su Zhao has exchanged the small Star Ship resource points of the Sirius level in the Arcturus Region.

After arriving in the alien zone, this resource point certificate is submitted to the relevant unit, which is equivalent to the corresponding starship owned in the sector, and according to the market price of the alien zone of the starship, it can be exchanged for the corresponding current star currency.

The starship's warp engine, antimatter crew and ion engine propulsion system ensure the stability of its value fluctuation range in different star regions, because these three major pieces basically account for 80% to 90% of the value of a starship due to their own production difficulty and the deliberate control of the Federation, and the value of any star with starship production capacity is not much different.

Starships as a whole, relying on their own interstellar navigation capabilities, have become the cornerstone of interstellar finance, and the resource point proof is also issued by those star sectors that can produce starships, radiating to the star sectors within the effective range.

This system enables the trade attribute of interstellar transportation to be brought into play, and it is also the basis for Su Zhao's commercial activities on the Trident, where he was originally located.

As for the anti-counterfeiting means of resource point vouchers, it is another set of complex and sophisticated measures.

In addition to the home star region, the federal human beings take the antimatter fountain as the core, the nearby high-level star region as the cornerstone, and then radiate outward to the celestial body region within the effective range, which constitutes a different star field.

Interstellar finance also refers specifically to the transportation and trade of goods within the star field, and as for beyond the star field, there is basically no need for trade, and there is no need to establish a financial system.

The reason is very simple, the distance is too far, the voyage is recorded for ten years, except for the exchange of some civilization and technology, there is no need for the circulation of personnel and goods, each star field can be said to be its own civilization individual, the development of the human federation in the past thousand years, with five independent star fields as members of the federation, three of which are developed in cooperation with the civilizations of the members of the interstellar federation, that is to say, only two star fields are completely self-established.

If the Silver Heart Theater can win the war, perhaps after hundreds of years of development, it will be able to become another emerging star field for the entire Interstellar Federation.
