Bitcoin mining: Bitmain could be divided after internal dispute

 

One of the most shocking fights in the world of Bitcoin mining, could cause the division of Bitmain. According to reports, the power struggle between the two major shareholders Wu Jihan and Micree Zhan Ketuan, would lead the company to create parallel sales and shipping departments.

The struggle for control of the company has been going on for a long time. However, it exploded last year when Wu decided to expel Zhan. The latter has been fighting to regain the company and recently won the favour of the authorities.

The dispute between the two former partners has led to serious supply problems for the manufacturer. Bitmain has been ceding control in the sales market to the competition from the powerful MicroBT.

Bitcoin’s mining equipment manufacturer, Bitmain, could be divided into two

Following Wu’s expulsion of Zhan last year, the problems became more radical within the leading mining ASIC manufacturer Bitcoin. In response, Zhan took over the company’s Beijing headquarters, with the support of the mainland authorities.

In the midst of these conflicts, Wu, trying to close the way for Zhan, registered a new firm in Shenzhen called Guiji Yanghang, which is subsidized by another supplier called Guiyuan Dalu, also on Wu’s side.

All of Wu’s plans were thwarted by Zhan’s struggle for control. The latter is now planning to create a new supply and manufacturing chain for Antminer equipment.

The June shipments of Bitcoin mining equipment in Bitmain’s S19 series were again delayed due to internal fighting.

What are the most important crypto companies in the world?

Loss of control in the market
Bitcoin’s mining ASIC manufacturer, Bitmain, could lose the competition to its rivals. The serious internal conflict of the Asian manufacturer is opening the doors for another big company to take Bitmain’s place.

This is the already mentioned MicroBT, which has developed the powerful M30S+ equipment, which mines with a 100T hash. At the same time, they have an efficiency of 30.00 j/TH, which puts them at the level of the Antminers of the most recent S19 series.

Bitmain’s clientele, affected by delays in shipments, which are the result of internal disputes, has turned its eyes to MicroBT. Since 2017, this company has gone from 6% to 30% this year. On the other hand, Bitmain dropped from almost 70% to 40% of sales in the international market.

Efficiency is the key in the ASIC market

The new battlefield will create more confusion
The new phase of the disputes between the two shareholders of Bitcoin Loophole mining company, Bitmain, could increase the levels of confusion among customers. The impact on the manufacturer’s position on the market would be catastrophic because of the threat of competition.

The confusion for global buyers could be that they do not know from whom to buy the equipment. In addition, this may be compounded by the uncertainty that their orders will be delayed or boycotted by one or other of the factions fighting for power in Bitmain.

Another important fact is that, last Friday, Wu sent a letter to the company’s employees. In it he accused Zhan of internal economic problems with the staff, alluding to the fact that the staff would have caused the loss of several hundred million dollars.

He also said that the shipment of Bitcoin mining equipment would have been affected by the disruptions in Shenzhen caused by Zhen’s arrival.

Autópsia de Hackers no Twitter: Coinbase, Binance, BitGo Pode Conhecer Hackers ID

Os hackers do Twitter deixaram discretos rastros de Bitcoin levando e saindo de grandes trocas que deveriam ser capazes de desvendar suas identidades.

Os hackers que conduziram o sequestro massivo do Twitter em 15 de julho não parecem ser usuários sofisticados do Bitcoin (BTC), pois deixaram rastros que levam a e de grandes trocas que presumivelmente guardam as chaves de suas identidades.

O endereço Bitcoin Circuit que os hackers usavam para solicitar doações ilícitas é bc1qxy2kgdygjrsqtzq2n0yrf2493p83kkfjhx0wlh. Um par de horas depois do hack, os criminosos começaram a mover Bitcoin para outros endereços. O rastro de Bitcoin que eles estão deixando para trás sugere que eles não são terrivelmente sofisticados quando se trata de tecnologia de cadeias de bloqueio. Eles estão reutilizando os mesmos endereços, não estão cobrindo seus rastros de e para as trocas o suficiente. Eles quase não têm usado nenhum serviço de mistura.

De acordo com as evidências na cadeia que coletamos, várias trocas importantes deveriam ter suas identidades.

Coinbase & BitMex

Vamos nos concentrar em um endereço a um salto do original – 1Ai52Uw6usjhpcDrwSmkUvjuqLpcznUuyF. Este endereço recebeu 14,76 BTC, a maior parte em 15 de julho; entretanto, o endereço foi ativado pela primeira vez em 3 de maio. Aproximadamente metade do BTC veio do bc1qxy, o restante de várias outras fontes.

Algumas das Bitcoin recebidas tiveram origem nas trocas de Coinbase e BitMex. Dois endereços identificados como pertencentes a Coinbase pela Crystal Blockchain, 37p3PS1hKqzYhiVswbqN6nxbwyUoTZvf1E e 32V6a7K46pSb1XQNGdrmdE2wjgndVfJPet, estão a dois hops de 1Ai52, o mesmo endereço que recebeu transações diretas do endereço original do hacker.

O que parece ser uma retirada de 10 BTC Coinbase ocorreu na manhã de 15 de julho. Algumas horas depois, 0,4 BTC originados da suposta retirada da Coinbase acabaram em 1Ai52U. Como não é uma rota direta, há a possibilidade de as moedas trocarem de mãos no intervalo. No entanto, isto parece improvável, considerando que não há entidades importantes no meio.

O que parece ser uma retirada BitMex de 3BMEXqT4yGBFiVBeJFHF4Ak5PyhqTnidKP está a três lúpulos de 1Ai52. Em 27 de abril de 14.18 BTC foi transferido desse endereço, em 3 de maio, acabou em 1Ai52U.

BitGo, Luno, Binance

Os hackers também usaram o endereço 1NWJd7BfJLJrEcfGiGfFqbhyaiusWwaZS1 para mover os fundos do endereço original. O primeiro também recebeu uma pequena quantidade de BTC do 14kWuX37tgLdYZDSudHuch35NtuGgJqqnz, que, por sua vez, recebeu BTC de vários endereços que parecem pertencer à BitGo. – A mesma transação 89a4ba84043d043d212216216718dae4ac3b74e6d08fd4575edab532c1c188dd961 enviou pequenas quantidades de BTC para várias outras bolsas, incluindo Bittrex, Luno e Binance (BNB).

Binância

Em 16 de julho, 0,0011 BTC acabou em 16ftSEQ4ctQFDtVZiUBusQUjRrGhM3JY identificado como um dos endereços de depósito do Binance. Está a três lúpulos de distância do endereço original do hacker, sem grandes entidades no meio.

Observações finais

Os hackers parecem estar usando um proxy, pois as transações são originárias de diferentes partes do mundo. Os endereços Bitcoin gerados pelos hackers vêm em diferentes formatos, alguns são do mais novo formato Bech32, outros nos formatos mais antigos P2PKH e P2SH. Se nossa análise estiver correta, então várias grandes entidades de criptografia devem ser capazes de identificar os hackers.

Cardano’s (ADA) Shelley Testnetz soll am 9. Juni für alle Pool-Betreiber geöffnet werden

Für Shelley steht eine neue Phase bevor, denn am 9. Juni wird das Testnetz für die Ära des Cardano-Einsatzes allen Betreibern von Einsatzpools offen stehen. Ab Mai stand das Testnetz „Freunde und Familie“ nur einer ausgewählten Gruppe von etwa 50 Stackpool-Betreibern offen, die den Weg für weitere Betreiber ebnen sollten, die sich anschließen wollen.

Jeder Pfahlpoolbetreiber kann nun dem Shelley-Testnet beitreten.

Etwas mehr als vier Wochen nach dem Shelley-Testnet im Freundes- und Familienkreis öffnet das für eine ausgewählte Gruppe von Pionieren geschlossene Netzwerk seine Türen für die breite Öffentlichkeit. Laut Tim Harrison, Marketing- und Kommunikationsdirektor des IOHK, wird das Shelley-Testnetz in eine neue, letzte Phase eintreten, die das Netzwerk von Bitcoin Future näher an die Freigabe des Hauptnetzes bringen wird.

In einem auf Twitter geteilten Video kündigte Harrison an, dass das Shelley-Testnetz am 9. Juni für alle Stake-Pool-Betreiber offen sein wird. Jedem Stake-Pool-Betreiber steht es frei, dem Testnet beizutreten, einschließlich derjenigen, die Stake-Pools auf dem Shelley Incentivized Testnet (ITN) eingerichtet und betrieben haben.

Die Benutzer werden in der Lage sein, den Betrieb von Delegations- und Pfahlpools zu testen und zu lernen, sich im Shelley-Netz zurechtzufinden. Harrison sagte, dass derzeit über 60 Pools auf dem Testnet laufen, und fügte hinzu, er hoffe, dass sich in den nächsten Tagen weitere Benutzer anschließen würden.

Er merkte jedoch an, dass die Benutzer nicht erwarten sollten, dass alles reibungslos abläuft – obwohl dies dem eigentlichen Shelley-Mainnet am nächsten kommt, ist die Umgebung immer noch ein Testnetz, das voller Bugs und Probleme sein wird.

Die neuesten Updates auf Bitcoin Future

Werden andere Betreiber die Stimmung der Pioniere gegenüber Shelley teilen?

Letzte Woche kommentierte Christopher Greenwood, der Leiter der Auslieferungsabteilung von Cardano, die Fortschritte, die im Testnet von Freunden und Familie erzielt wurden, und sagte, dass die Pioniere „überwältigend“ zufrieden mit der Erfahrung oder dem Betrieb von Pfahlpools seien.

Die Pioniere haben alle Übungen im Testnet durchlaufen, einschließlich Delegieren, Ändern von Pool-Parametern und Einreichen von Transaktionen, wobei die meisten sagten, die einzigen Fehler, auf die sie gestoßen sind, seien „kosmetischer Natur“ gewesen. Dies, so Greenwood, wird ihnen helfen, die übrigen Operatoren, die sich am Testnet beteiligen, zu schulen, wodurch das IOHK selbst von einem Großteil der Last befreit wird.

Diejenigen, die daran interessiert sind, Pfahlpools im Shelley-Testnetz einzurichten und zu betreiben, können auf der offiziellen Testnet-Website auf alle erforderlichen Unterlagen zugreifen.

Die morgige Öffnung des Shelley-Testnetzes für alle Betreiber von Pfahlpools verläuft nach den zuvor dargelegten Plänen. Mehr Menschen in die Shelley-Testnet-Umgebung zu lassen, ist der letzte Schritt, den das Unternehmen unternehmen wird, um Cardano von einem föderalen zu einem dezentralisierten Proof-of-Stake-System umzuwandeln.

Was die zukünftigen Pläne für Shelley betrifft, so sagte Harrison heute Morgen, dass die Einspeisung in das Shelley-Hauptnetz im August verfügbar sein wird. Das bedeutet, dass die Inhaber von ADA bis zum Ende des Sommers warten müssen, um durch Absteckung oder Delegierung am Netz teilnehmen zu können.
