比特幣完成減半之後，超 50% 礦機已關機或瀕臨關機狀態

律動 BlockBeats 消息，據幣印礦池數據顯示，比特幣減半後，按當前幣價計算，在非豐水期電價（0.37 元）情況下，螞蟻礦機 S19 Pro、神馬 M30S+、芯動礦機 T4+等新一代高算力礦機電費佔比已幾乎達到 50%，淨收益較比特幣減半前的 90 元/天下降約 66%，當前收益僅爲 30 元/天。而同樣也是剛推出不久的新礦機 S17 系列，神馬 M31s 系列等每日淨收益已不足 10 元。螞蟻礦機 T17、神馬 M21s、芯動 T3、阿瓦隆 A1045 等多個礦機已達到關機幣價。

若按照豐水期電價（約爲 0.22 元）計算，其中螞蟻 S19 Pro 日淨收益近爲 41 元，神馬 M30s 日淨收益爲 41 元左右。如果考慮礦場其他運維成本，收益或還會減少。不過豐水期對老礦機來說還是最後一個機會，豐水期電價下，螞蟻礦機 T17 系列、神馬 M21s、芯動 T3 等礦機仍可保持每日 16 元左右的淨收益。

不過，不論是否處於豐水期，老一代機皇 S9 都應已完成使命了。即使豐水期電價的情況下，S9 系列礦機如果開機，也是在關機邊緣試探，其中S9雙筒每日收益僅爲2.5元，而 S9 礦機每日淨虧損 1.77 元左右。

按此前比特大陸吳忌寒預計，減半後全網算力或將下降 20%。目前來看，全網超半數礦機在非豐水期電價的情況下已經達到關機幣價或瀕臨關機幣價。即使豐水期電價下調，對於礦業來說仍是一大挑戰。S9 似乎已經無力迴天，而幾乎 2018 年左右推出的礦機也已不具備算力優勢。早期佈局新礦機的礦工或可佔領更大市場。

The program is currently being tested online for Security Review and will first attempt to integrate with the ETH blockchain. According to the law, all processes of generating random numbers can be divided into two categories: true random numbers and pseudo random numbers. True randomness can be generated by some basic procedure, such as rolling dice or flipping coins. PSEUDORANDOM is generated by computation, usually with the aid of the PSEUDORANDOM number generator number generator, PRNG. In practice, the latter is more prominent because it can be easily integrated into a variety of computer applications. The key is to ensure that the random numbers generated by these algorithms are indeed unpredictable. Until now, even decentralized applications have had to rely on random centralized sources. CHAINLINK's solution to this problem uses old cryptographic primitives and utilizes a decentralized incentive mechanism. A smart contract that wants to take advantage of Chailink's VRF, passing a seed to a node, which then uses its key to generate a random number. The results are posted on the chain along with the proof of the password. Anyone can verify it with an oracle public key, just like a bitcoin signature. A malicious node can not return a forged random number because the signatures do not match and the malicious node faces a fine. The first use case currently being explored is lossless lottery pool together. Although it is called a "game" , it is more of a mechanism to stimulate savings. Participating customers lock up the principal and purchase the "deposit ticket" . One vote and one draw will win the reward. But participating users can get their full principal back even if they don't win the Grand Prize. So far, the game's game administrators have been using highly centralized random resources, which could be a source of contention. As for CHAINLINK's solution to some of the game's problems, Chainlink's founder and CEO said, "in Blockchain Games, my view is that decentralized blockchain games will not be affected by centralized games. ". The problem with Centralized Games is that they focus on the idea that the people who create them are manipulating them for their own benefit, or that they are devaluing the goods in the game. "
