據說是今天比特大陸的出貨文 https://www.reddit.com/r/Monero/comments/84kkw2/antminer_x3_220kh_at_550w/ https://goo.gl/DhiEzq 原來已經有這種東西好一陣子了啊 說不定 CryptoNight 系列幣難度變超高不是 bot net 害的 看來是 3/28 XMR 要升級所以才開始賣 如果 XMR 真的改算法的話,還沒出貨就變磚了 XDD --------------------------------------------------- 全新挖 CryptoNight 幣的 螞蟻礦機X3 上市 -- 8 分鐘前 All new Antminer X3 to mine CryptoNight coins! webmaster@bitmaintech.com to me 8 minutes ago 親愛的讀者, Dear subscriber, 我們非常高興地宣布我們將發表全新的螞礒礦機 X3 -- 挖 CryotoNight 演算法幣的新系列礦機 We are proud and happy to announce that we are launching the all-new Antminer X3, a new Antminer model for mining cryptocurrencies based on the hashing algorithm CryptoNight. 新的螞礒礦機 X3 在消耗 550W 的情況下至少提供 220 KH/s 算力 The Antminer X3 delivers a minmum hashrate of 220KH/s while consuming 550W of total power. 為了避免某些人/經銷商屯貨並保證全球各時區人人都買的到礦機,我們做了以下改進 To prevent hoarding by certain users or resellers and to ensure that more individual miners in different time zones around the world are able to order this new ASIC miner, we have made some changes: 這兩批貨一單一人限購一機。我們將於今天分三次均勻釋出這兩批貨 三月十五 下午 3,6,9 點 (GMT+8) 。點擊下面看價格及出貨時間 There is a limit of one miner per user for all orders in the current (two) batches. We will release both these batches with an equal stock thrice today: at 3PM, 6pm and 9PM (15 March, GMT+8). Click below to learn the price or to order after the scheduled time of launch: 商品頁面:11999 鎂 From product page: 11999 USD 算法:CryptoNight 功耗: 550W 算力:220KH/s Hashing algorithm: CryptoNight Power consumption: 550W Hashrate: 220KH/s 這是最保守的估計,我們指望礦機在準備好出貨時能提供更高的效能和效率 These are the most conservative estimates. We expect the miners to deliver higher performance and efficiency when they are ready to ship. 挖礦有財務上風險,這些風險可能和加密幣的匯率改變、挖礦算法的改變有關。 請在購買前仔細考慮因為我們這批貨將不接受任何行式的退款。 2. There are financial risks associated with mining cryptocurrencies. These risks can be related to changes in exchange rate of the cryptocurrency or to changes in the algorithm that is used to mine the cryptocurrency. Please deliberate well before making a purchase because we will not accept any requests for refund for orders of this batch. 為了確保全球更多買家可以買到這批礦機,我們每人限購一機 To ensure that more buyers around the world can purchase miners in this batch, we have set a limit of one miner per user . 送出單前請填入收貨正確地址。因為這批貨下單後無法改變收貨地址 Please select the correct address for shipping before you submit your order because, for this batch, the shipping address cannot be changed after the order has been submitted. 最近我們的物流提供商已更新運費。故,4 月後出貨的批次運費可能些微不同 (可能會較低) 於 4月前出貨的批次 The shipping cost has been updated by our logistics’ service provider recently. Therefore, the shipping cost for batches that are to be shipped after April 2018 will be slightly different (likely lower) than those that are to be shipped before April 2018. 本批出貨順序先下單先出,於 5/15 出貨那些比特大陸已收到款的訂單 我們建議你事先研究並準備你的國家的海關申報,以避免延誤及出現預料外的費用 The shipping for this batch will start on a first-order-first-ship basis on 15 May 2018 for orders that Bitmain has received full payment for. We advise you to research and prepare in advance for the customs' clearance in your country to avoid delays or unexpected costs. 你會需要至少 10 個 6pin pcie 接頭的 ATX 電供。每個 hashing 板上有 3 個 6pin 接頭。全部三個都要接上電供。比特大陸建議 X3 使用 APW3++ You will need an ATX PSU with at least 10 six-pin PCIe connectors. There are 3 six-pin PCIe connectors on each hashing board and all three need to be connected to the PSU for the hashing board to operate. Do not connect more than one PSU to the same hashing board. Bitmain recommends the APW3++ to power the X3 將控制板另外功電: IO 板上有另外一個 6pin pcie 接頭要接上電供。 請確定所有 10 個 pcie 接頭都接上電供後再開機 Separate power supply to control board: there is one additional six-pin PCIe connector on the IO board which must be connected to the PSU to get power. Be sure to power on the miner only after all the 10 PCIe connectors are connected to a power supply. -- ※ 發信站: 批踢踢實業坊(ptt.cc), 來自: 123.195.1.63 ※ 文章網址: https://www.ptt.cc/bbs/DigiCurrency/M.1521117921.A.477.html ※ 編輯: HamalAri (123.195.1.63), 03/15/2018 20:49:06 ※ 編輯: HamalAri (123.195.1.63), 03/15/2018 20:51:21 ※ 編輯: HamalAri (123.195.1.63), 03/15/2018 21:05:42

35萬一台,現在幣值難度算只要63天回本
03/15 21:29, 1F

03/15 21:50, 6年前 , 2F
5/15出貨...XD 應該足夠全cryptonight幣都改pow了XD
03/15 21:50, 2F

03/15 21:56, 6年前 , 3F
XMR是確定會改pow,其他不改的立刻就會面臨51%攻擊風險
03/15 21:56, 3F

03/15 22:39, 6年前 , 4F
快速換算法分叉是考驗各幣的研發能力
03/15 22:39, 4F

03/15 23:49, 6年前 , 5F
其實都是直接拿XMR的來merge就好了阿
03/15 23:49, 5F

03/15 23:52, 6年前 , 6F
XMR只是微調現行的POW為cryptonight variant 1
03/15 23:52, 6F

03/15 23:52, 6年前 , 7F
接下來每半年的分叉都會調一次 直到開發出真正抗ASIC pow
03/15 23:52, 7F

03/15 23:53, 6年前 , 8F
以半年週期來看 ASIC很難跟得上設計生產所需的時間
03/15 23:53, 8F

03/16 04:05, 6年前 , 9F
意思是之後XMR收益會變高?
03/16 04:05, 9F

03/16 11:01, 6年前 , 10F
如果目前全網算力已經很多ASIC在挖就代表分叉會降不少算力
03/16 11:01, 10F

03/16 11:02, 6年前 , 11F
難度也就會下降 所以收益應該是會回升一些 但也沒人說得準
03/16 11:02, 11F

03/16 11:03, 6年前 , 12F
就期待3/28見真章啦 哈哈
03/16 11:03, 12F

03/16 11:42, 6年前 , 13F
只做crytpnight微調的話,也許有風險
03/16 11:42, 13F

03/16 11:42, 6年前 , 14F
ASIC雖然不能改算法,但可能預留
03/16 11:42, 14F

03/16 11:42, 6年前 , 15F
應付預測未來可能的小改動。
03/16 11:42, 15F

03/16 11:42, 6年前 , 16F
有一點configurable能力。
03/16 11:42, 16F

03/16 11:47, 6年前 , 17F
當初crytonight被形容Asic resistance
03/16 11:47, 17F

03/16 11:48, 6年前 , 18F
是認為2MB資料容量,對於一般
03/16 11:48, 18F

03/16 11:48, 6年前 , 19F
ASIC
03/16 11:48, 19F

03/16 11:48, 6年前 , 20F
只有微小cache/ram很困難
03/16 11:48, 20F

03/16 11:48, 6年前 , 21F
但又小到剛好足以塞進CPU cache
03/16 11:48, 21F

03/16 11:49, 6年前 , 22F
而亂數讀取特性不利於GPU+GDDR5
03/16 11:49, 22F

03/16 11:50, 6年前 , 23F
所以XMR能CPU+GPU雙挖,而無ASIC
03/16 11:50, 23F

03/16 11:59, 6年前 , 24F
但ASIC會進化,2MB顯然不是問題了
03/16 11:59, 24F

03/16 12:49, 6年前 , 25F
演算法也會進化阿,只要確定要對抗,ASIC是跟不上分叉的
03/16 12:49, 25F

03/16 12:51, 6年前 , 26F
只要Monero沒有放棄對抗ASIC,無論是微調或整換都在討論中
03/16 12:51, 26F

03/16 13:06, 6年前 , 27F
甚至有出現極端方案:ASIC friendly https://goo.gl/64PS8d
03/16 13:06, 27F

03/16 13:09, 6年前 , 28F
這就是我喜歡Monero社群的原因 只要有改進的可能性 即使與
03/16 13:09, 28F

03/16 13:10, 6年前 , 29F
核心團隊現行方針違背的方案也都可以攤出來討論觀點
03/16 13:10, 29F

03/16 15:13, 6年前 , 30F
看來要挖XMR用FPGA才是王道
03/16 15:13, 30F

03/16 16:20, 6年前 , 31F
大資本永遠會掌握最多的算力,給誰賺而已
03/16 16:20, 31F

03/16 22:03, 6年前 , 32F
最多,不一定是夠多。
03/16 22:03, 32F

03/16 22:04, 6年前 , 33F
因為PC運算裝置是全球灑.
03/16 22:04, 33F

03/16 22:04, 6年前 , 34F
大資本也沒有很大利潤優勢。
03/16 22:04, 34F

03/16 22:06, 6年前 , 35F
ASIC可以一台抵千台萬台pc
03/16 22:06, 35F

03/16 22:06, 6年前 , 36F
但GPU礦機就大致1台抵1台。
