MARBLE 2019 of conference of international of research of maths of economy of catenary of first area piece is in at present Greek Shengtuolini is held. Official data shows, area of MARBLE 2019 focusing piece the mathematical research of catenary backside, the chasm between close practice and theory, scientist of the mathematician that aims to be world center, computer and economist provide communication platform, show the newest progress with academic key of area piece catenary and innovation gain.

Wu Ji of author of bit mainland combination is cold participated in this second congress, it is on the meeting around add close money and dig mine and why should choose wide the PoW that gets dispute and ASIC mine machine made a presentation.

Look in him, the existence of PoW is to solve double paying issue, substantially it is mode of economy of a kind of market.

On the conference, london king institute adds close money to reach go to a center changing systematic expert Patrick McCorry to taught cold to Wu Ji speech to undertake whole journey direct seeding, it is to come from Patrick McCorry to push below special Zhang date is cold to Wu Ji of speech text delimit key:

PoW consensus is most intuitionistic to supply and demand reflect, not be the program that turns through the center, move through economic drive however. A system that goes to a center changing, should contented anybody is OK participate in competition with fair drive.

Why do we want a care to go to a center changing? 3 reasons: The stability on social bond level - can change fixed contract without central influence orgnaizationThe network is stretch - shut individual node to won't affect network operationCapital is safe - can be frozen without central orgnaization or operate trade

Specific and character, wu Ji is cold the center goes changing in what 3 dimension spoke of spending in the speech, administer dimension to spend namely, physical dimension is spent and market dimension is spent. In processing dimension is spent on, he discussed examination and balance system. Market dimension is spent on, all participator should can participate in freedom and fair competition, fair land measures his workload.

He also spoke of, the market also can be out of order, and brought about the occurrence of the PoW that the center changes.

Go-between of the industry that dig mine is the obstacle of the setting. E.g. , after bit money two after arriving 3 years, a few added close money to introduce admittance license to dig mine. . . . In addition, return the price twist that somebody causes to operate.

He speaks of drive finally not quite sufficient. For instance, a few colliers are not to stem from economic purpose digging mine (for example BSV) , stem from however a few otherer factitious reason is digging mine.

Wu Ji is cold think, everybody can bring about a center to change to ASIC is a kind of misunderstanding. In fact, use GPU digs the aether lane network of mine, also can bring about a center to change. The XMR to preventing ASIC actively also is such likewise.

And ASIC of use bit money digs mine algorithm, the circumstance is not met more flooey. At present control of the biggest two mine pool comes in 28.3 ％ of 34.3 ％ calculate force. This is close friends more than the circumstance 2014. (but prove two mine pool puts in same person 's charge very hard all) .

To a lot of add close money for, do not think to just use the mine machine that fights ASIC because of what design, be based on pair of collier cost however think, because fight the mine opportunity cost of ASIC a lot of lower.

The occurrence of special mine machine is inevitable, it is the inevitable result that opens competition freely, choose by the market.

And trying to design the mine machine that fights ASIC just have a problem, unfair competition is for the person that uses ASIC mine machine to those especially.

In addition, use GPU digs another problem of mine to depend on, it is controlled by two big companies, include AMD and Nvidia. This lets manufacturer of new mine machine hardware enter become very difficult.

Wu Ji is cold still raised cost / the concept of operation rate, he thinks, ASIC won't bring about a center to change not only, can promote instead go to a center changing.

Specific and character, if of mine opportunity cost and operation expenses lower than jumping over, gain gets more easily the influence of electric power cost.

E.g. , buy machine of mine of a ZEC very expensive, but the elapse as time, can become cheaper and cheaper, to it contrary, of the cost of bit money and operation expenses than relative balance.

This is meant, ASIC can be driven instead go to a center changing.
