關注 cryptocurrency 增長, 對採礦設備的需求都增加了. 幾年前, 每個人都可以使用足夠強大的電腦, 成為礦工, 在過去的一年裡, 形勢發生了翻天覆地的變化, 以前的採礦方法已經變得無效。. 我哋有預測採礦的趨勢將是最受歡迎的 2018.
今日採礦需要相當昂貴的設備, 尤其係, 圖形卡. 去年6月中國在線交易平台通報告說, 它的用戶開始更積極地尋找特定型號的圖形卡, 最適合於創建採礦場. 俄羅斯礦工中最流行的車型係 nvidia 显卡-geforce gtx 1060 與 gtx 1070, 以及 Radeon RX480, 先進的微器件製造 (amd).
呢啲模型不僅喺俄羅斯礦工中流行, 過去的年標誌著 amd 同 #8217 嘅股票上漲 64%, 而 nvidia 公司證券的價值獲得爭啲 88% 自開始 2017. 專家表示, 增長歸囙於 ethereum 網絡和其他受歡迎嘅 cryptocurrencies 嘅礦工數量增加. nvidia 公佈嘅數據說明 6.7% 第二季度的收入 2017 從圖形卡銷售收到, 用於加密挖掘. 就係點解兩家公司同華碩公司已經開始發行獨特嘅圖形卡, 為 cryptocurrency 採礦設計. 也, last summer we knew that AMD was working on 7nm 48 core processor called Starship that would be released in 2018.
Experts, however, warn mining equipment manufacturers that demand for their products is going to shrink. According to Joseph Moore, an analyst at American bank holding company Morgan Stanley, 採礦可能成為一個經濟上無利可圖嘅活動 2018.
“我們相信, 在 ethereum 採礦總圖形銷售 2017 黎緊 $800 百萬左右, 並將下降 50% 在2018年。”
摩尔同 #8217 嘅觀點, 低迷的第一個原因係計劃喺 ethereum 網絡的整體獎勵下降 5 理工學院 3 eth. 第二係由工作證明嘅轉變 (戰俘) 證明利害關係 (pos) 而唔係採礦權, 創建塊並接收相關獎勵的概率與系統中用戶的所有權比例成正比. 维杰勒凯什·索德, 日本投資銀行瑞穗銀行分析師, 又提到這種傾向. 他相信, 在上半年 2018, cryptocurrency 開採的圖形卡就唔再需要, 如乙醚開採.
“我們相信, ethereum 期待在未來六月內轉移到不同的付款驗證系統, 由 proof-of-work 的使用圖形卡到 proof-of-stake 的圖形卡唔再需要。”
The project of modifying consensus protocol of Ethereum network is called Casper. It implies that specialized computer equipment is not needed anymore to create a new block; instead, users will be able to provide their own funds that would be frozen for a while, and in return, they will have the opportunity to participate in transactions confirmation. 因此, Casper will create a system that could resist mining centralization. Once the next fork Constantinople, which can occur at the beginning of 2018, takes place, the Ethereum network update will be activated.
Despite the potential change in consensus protocol of the Ethereum network, the head of Nvidia, Juan Zhjensjun, is sure that revenue made from GPU (graphics processing unit) sales for crypto mining would remain, asserting cryptocurrencies and blockchain are “here to stay.”
“This is a market that is not likely to go away anytime soon, and the only thing that we can probably expect is that there will be more currencies to come. It will come in a whole lot of different nations. It will emerge from time to time, and the GPU is really quite great for it.”
ASIC (Application-Specific Integrated Circuit) that exists in the form of chips was created for effective mining as well. ASICs are used for a specific device and carry out strictly limited functions, which makes execution of these functions cheaper and faster. The chips are more powerful and consuming much less energy; they are many times more profitable than graphics cards. 此外, mining farms require more time to spend on the assembly and completion, while with ASIC-miners you are all set.
This year it was revealed that companies, such as Samsung, Intel, TSMC, and Global Foundries, were developing 7nm chips for ASIC mining. Chips production is scheduled for the first quarter of 2018. They will have improved energy efficiency compared with the previous 14nm chips.
Japanese Internet giant GMO plans to launch a new ASIC-Miner that would be based on 7nm chips. 呢項技術嘅大規模芯片生產計劃五月 2018. 明年轉基囙生物將推出 ico 出售下一代採礦板. 佢哋將發行令牌作為購買下一代採礦板嘅方法. 除咗, 公司計劃喺北歐建立礦業中心:
“我哋將喺北歐使用可再生能源和 cutting-edge 半導體芯片運營下一代採礦中心. 我哋將使用 cutting-edge 7nm 工藝技術, 用於在採礦過程中使用的芯片, and jointly work on its research and development and manufacturing with our alliance partner having semiconductor design technology.”
Last September, Russian Miner Coin (RMC) conducted ICO to support the production of a new miner Sunrise with Bitfury chips and develop another new miner Multiclet with the same chip. The ICO collected $43.2 百萬. RMC involves 15 businesspeople and cryptocurrency activists and unites four companies, including MultiClet, SMARTHEAT, GOODWIN, and RadiusGroup. The company has started Miner Sunrise production and, by the next summer, intends to develop a next-generation processor Multiclet, which will be 35 times more efficient for mining.
It is evident that powerful and expensive equipment, which is extremely energy consuming too, is needed for successful mining. That is why companies have developed an alternative type of mining, called cloud mining. Companies with powerful data centers provide equipment, and lease their resources to the final consumer. Once the contract is concluded and the services are paid, companies such as Hashflare, Genesis Mining, Bit Miner, and OxBtc provide access to mining of several cryptocurrencies.
These services are already trendy. There is no reason to believe that this trend will slow down in 2018, as the cloud mining is an affordable, 可靠, and convenient way to get cryptocurrency, that does not require any expensive equipment. There are some possible drawbacks. The seller of cloud mining contracts can be unfair; a site that provides this type of service may be vulnerable to hacking attacks; users have no control over the commission fee they receive for mining; moreover, unplanned losses may force data center to pay back less to its users under the following contracts.
Currently, no laws are governing the mining activity in Russia and other countries either. The Russian President decree, however, says that the Government and the Central Bank will have to establish taxation and registration order for mining companies the next summer. This initiative will supposedly refer to both companies and private miners.
於12月, the Commissioner under the President of the Russian Federation on protection of the rights of entrepreneurs, Boris Titov, proposed to introduce a tax on crypto mining at the rate of 14%.
