Alliance: Loch Modan and Duskwood

Kalimdor (It is particularly difficult to collect silver in Kalimdor, so it may be easier to keep collecting tin until you reach 125)

Neutral: Ashenvale

After collecting enough ore to reach 125, you should return to the trainer and learn Advanced Mining. After this stage, all mineral points will appear in disputed areas.

3.: Iron ore and gold ore

Iron Ore/Iron Ore Vein (Requires Mining 125)

eastern kingdom

Duskwood, Alterac Mountains, Arathi Highlands, Badlands

In Duskwood, the best route starts at the border closest to Stranglethorn Vale, continues along the border of Swamp of Sorrows, then ends along the ridge near Darkhold and circles outside of Duskwood.

In the Badlands, the standard route is fine, but you can also complete a smaller route on the cliffs between Kargas and the volcanic caves for extra speed.

Kalimdor

Thousand Needles, Desolace, Ashenvale, Tanaris

In Desolace, the most efficient route starts at Shadowburst Village.

In Ashenvale, you just need to circle around the east side of the area.

To gather in Tanaris, the quickest starts in Gadgetzan, goes around the outside of the Caverns of Time, and then returns to Gadgetzan.

Gold Mine/Gold Vein (Requires Mining 155)

eastern kingdom

Burning Steppes, Alterac Mountains, Arathi Highlands, Badlands

In the Badlands, in addition to the standard, larger routes, it is possible to create mini routes identical to those used to collect iron ore.

Kalimdor

Tanaris, Thousand Needles, Un'Goro Crater

In Thousand Needles, you can stop your path and turn around at the edge of the Shimmering Plains.

In Un'Goro Crater, the highest concentration of gold is on the northwest edge.

After completing these mining routes, you can train to Expert level! When you reach Expert level and start collecting Dark Iron Ore, it will be necessary for you to go to the Eastern Kingdoms because Dark Iron Ore does not generate in Kalimdor.

: Mithril ore, true silver ore, black iron ore, thorium ore.

Mithril Ore/Mithril Vein (Requires Mining 175)

eastern kingdom

Burning Steppes, Alterac Mountains, Arathi Highlands, Badlands

In the Badlands, the same route used for tin and gold can be followed.

In the Alterac Mountains, mithril is concentrated around the ruins of Alterac.

Kalimdor

Tanaris, Desolace, Azshara

In Desolace, the most efficient route is to build a route around the valley.

In Azshara, your route should follow this road until you reach the Ruins of Edarath. After that, you need to follow the mountains north of the ruins, then along the northern edge of the area, around the mountains on the northeast coast, and back to the ruins.

Truesilver Ore/Truesilver Vein (Requires Mining 205)

eastern kingdom

Burning Steppes, Blasted Lands, Arathi Highlands, Alterac Mountains

The largest concentration of truesilver ore in the Burning Steppe is the Greatmaul Stone.

In the Blasted Lands, truesilver does not generate at all in Mark of the Blade.

In Alterac Mountains, you can follow the same route as for Mithril Ore.

Kalimdor

Tanaris, Azshara, Un'Goro Crater

In Tanaris, the most truesilver generates along the mountains on the western edge of the area, so you should be able to do a loop with them.

The route you take for mithril in Azshara also works for truesilver, but the spawns are much rarer.

In Un'Goro Crater, the truesilver spawn is located to the southeast of the area, making it possible to reach where you stopped collecting gold previously.

Dark Iron Ore/Dark Iron Ore Vein (Requires Mining 230)

eastern kingdom

Burning Steppes, Searing Gorge

Thorium Ore/Thorium Ore (Requires Mining 250)

eastern kingdom

Burning Steppes, Felwood

The recommended location is Burning Plains or Felwood. There are several mining spots in Fatty's Cave, but it's not easy to figure out which cave they are in, so if you are not very familiar with the conditions in the cave, it is recommended not to mine them. . Just go around the mountain. You don’t need to stay in these two places for a long time, just get to 275.

Thorium Ore, Arcane Crystal/Rich Thorium Vein (Requires Mining 275)

eastern kingdom

Feralas, Silithus, Winterspring

The recommended location is the wormhole in Silithus. This is absolutely paradise. As long as you choose the time so that no one can grab it, you will reach 300 in no time. The key is to be familiar with the wormhole map. Or you can choose to go to Winterspring Valley. There are also many rich ores there, but the map is too big and tiring to run.

Once your mining level reaches 275, you can go through the dark portal and learn the Mining Master.

Outland

4.: Demonic iron ore, adamantine ore

Magic Iron Ore/Magic Iron Ore Vein (Requires Mining 275)

Hellfire Peninsula, Zangarmarsh

After you've mined enough sharpened iron, you'll start collecting adamantite, but there are two different veins at different levels: an adamantine-rich vein at 325 and adamantine-rich vein at 350.

Generally speaking, "rich" or "pure" points will produce more ore and have a higher chance of dropping rare minerals (in this case eternite ore). In this case, adamantine-rich veins have an additional unique advantage. After players reach 350, most people usually head to Northrend and start mining cobalt ore immediately, but this creates a lot of competition in the starting area. To circumvent this, you can continue collecting adamantine-rich ores until you reach 375 and speed up the upgrade process in WLK content.

Adamantite Ore/Adamantine Vein (325) + Rich Adamantite Vein (350)

Adamantite Ore(325)

Nagrand, Terokkar Forest, Blade's Edge Mountains

In Nagrand, you can exclude the area around Washu Valley from your route.

In Shadowmoon Valley, start near Legion's Keep, follow the path southeast to Illidari Post, north to Hand of Gul'dan, and then directly back to Legion's Keep.

In Netherstorm, start south of Mana Forge Bunar, head east to Kirin'Var Village, north to Mana Forge Utis, and then west to Forge Base. From there then pass through the ruins of Enkat and return to Bunar.

Whether you choose to stay in Outland or not, once you reach 350, you can head to Northrend and become a Grandmaster Miner.

Northrend

5.: Cobalt ore, Saronite iron ore

Cobalt Ore and Saronite also generate in rich veins. For these, they occur in relatively similar locations to standard nodes, so you can continue to make standard routes while specifically looking for them. Additionally, there is a location where pure veins of Saronite iron can be found, discussed below.

Cobalt Ore/Cobalt Vein(350)+Cobalt-rich Vein(375)

Cobalt Vein(350)

Borean Tundra, Grizzly Hills, Howling Fjord

Cobalt-rich veins(375)

Borean Tundra, Grizzly Hills, Howling Fjord

Saronite Ore/Saronite Vein (400), Rich Saronite Vein (425), + Pure Saronite Vein (450)

Saronite Iron Ore Vein(400)

Icecap Glacier, Sholazar Basin, Storm Cliffs

Fusalongite Iron Ore Vein(425)

Icecap Glacier, Sholazar Basin, Storm Cliffs

Pure Saronite Iron Ore Vein(450)

The only pure Sharonite vein occurs in Ulduar. After completing most of the raid and reaching Yogg-Saron's prison, players will have to defeat General Vezax. In his room, before the final encounter, there is a vein of pure ore that has a chance to generate. Unlike other pure veins, this vein does not have a chance to provide rare Titanite ore, but it does have a chance to produce Eternal Shadows and Eternal Earth.

With that, you've completed your upgrade! Congratulations! Read on to learn about Titanium Ore, Titan Steel Ingots and their potential to bring you huge profits.

Summary (Titan Iron and Titan Steel)

Regardless of whether you use the ore for crafting or not, all miners can benefit from collecting Titan Iron Ore. It is a key material in many high-level equipment. The ore is collected from Titan Iron Veins. It is most abundant in Icecrown Glacier, Sholazar Basin, and Storm Peaks, but be careful! Competition in these locations is usually very fierce.

Titan iron ingots are also the main material for making Titan steel ingots. Even more so than Titanium, Titanium Steel is coveted by all professions that require bar making. Besides Saronite, it is the only mineral used in crafting ToC and ICC drawings and enchantments. It is also the primary material used in crafting coveted engineering items.To make Titansteel, you need to smelt Titansteel, which requires: 3x Titanium Bars + 1x Eternal Flame + 1x Eternal Earth + 1x Eternal Shadow

So the above is all about how to level up 1-450 mining in World of Warcraft. I hope it will be helpful to you.

What goes with the WLK mining profession in World of Warcraft?

If you want to make money, just double mine and add herbs. If you want to make some money and improve yourself a little, choose some majors that don't require minerals, such as enchanting, inscriptions, etc. I just mine and enchant. , Niutou ZS; mining and forging are good in the early and late stages. You can make some equipment and sell them. Mining and jewelry may be more popular. After all, not many people learn jewelry but not mining, unless they are high-end rich people.

Which one is better, wlk mining or medicine gathering?

medicine, mining. You can study two majors in one profession. In this gathering profession, mining to earn gold is definitely much faster than gathering medicine, especially in WKL, all the diligent miners are game millionaires.

As far as 74 is concerned, I personally recommend mining and forging. That is to say, it can ensure that there is sufficient G, and it can be used to forge 3 series equipment. The equipment made by wlk is of very high level. For 74, there are already many blood-increasing skills, and adding some endurance is really useful.

Will wlk mining produce sapphires?

WLK mining will produce sapphires

Blue gemstones can be mined.

There are three ways to get purple gems:

1 As long as you have money, the simplest and most direct way is to buy it directly from the auction house.

2 badges can be exchanged for gems. There are NPCs in Dalaran who can exchange them for gems.

3 Honors are exchanged for gems, the Alliance is in Stormwind City, and the Horde is in Orgrimmar.

Where is the magic iron ore in wlk?

Distribution location of magic iron ore

1. Magic iron ore is produced from magic iron veins, most of which are found in Hellfire Peninsula;

2. In addition, Terokkar Forest (63), Zangarmarsh (51), Shadowmoon Valley (49), Nagrand (45), and Blade's Edge Mountains (35) also have refresh locations. Mining skill points of 275 are required to collect magic iron ore. point.

Magic iron is a trade item, and the selling price is 10 gold coins. This magic iron ore is still sought after by many players!

Mining is perhaps the most important and profitable gathering profession in all of World of Warcraft. Ore collected by miners is smelted into essential materials for engineering and blacksmithing, and raw ore is explored for gemstones by jewelry processing. As a result, demand for ores and various ingots is usually high, allowing sellers to control the market more directly than either herbs or skinning spells. After reaching max level, miners can also produce Saronite iron ingots and Titan steel ingots, which are the two most important final crafting materials.

The most important skill in mining is finding minerals. It functions similarly to Herbalism's finding herbs and Fishing's finding fishing spots, and displays ore locations on your minimap. Once you find a vein, you need to use your miner's hoe to dig for it. Engineers are also able to craft special tools to replace the miner's hoe, such as the gnome saber and hammer pick.

Learning the old world of mining

Like most other professions, a trainer in any main city can teach you from apprentice to master, so at this stage you need to go to a specific city to learn. You can also mine while upgrading with your character, so that you can practice the corresponding mining skill level on a map that is similar to your own level.

However, as explained in the next section, it is easier and faster to train your mining in the Eastern Kingdoms in order to get a balance between your own level and your mining level, so the Alliance should consider visiting Gilflam Stonetoe in Ironforge (50.0, 26.3) or Stormwind’s Gilman Stonehand (59.3, 37.8). Likewise, the Horde should consider finding Brom Killian in Undercity (56.0, 37.5) or Belil in Silvermoon (78.9, 43.2).

Outland

Upon arriving in Outland through the Dark Portal to Outland, the Mining Training Master will be located in your faction's first mission area. For the Alliance, it's Honak Grimaud of Honorfort (56.7, 63.9), while for the Horde, it's Krugesh of Thralmar (55.4, 37.6).

If you have access to Shattrath, you can also find two neutral trainers: Furnor of Aldor (36.1, 48.7) and Hanliel of the Astrologer (58.8, 75.1).

Northrend

In Northrend, the Grand Master Mining Trainer should be with all the other Grand Master Class Trainers after you land in your camp from the airship. The Alliance needs to find Findrig Redbeard (57.7, 66.1) in Dauntless Fortress, while the Horde needs to find Broanna Ironaxe (42.6, 53.2) in Warsong Fortress.

Jedian Handles is an additional neutral trainer if you have access to Dalaran, but since you have to actually be out there collecting ore rather than learning new blueprints, you can definitely learn it in the first mission area Mining and no need to rush to Dalaran.

Mining skill level

Like most other mining professions, the quickest way to find mineral spots and improve your mining skills is to cycle around the outer borders of a zone. Connecting all mining sites with the shortest distance is called the "optimal line" and is the most desirable route for mining. When areas are mentioned below, this collection strategy should be to complete the optimal line unless stated otherwise. While it may seem tedious, it will help you reach max level faster than other methods.

old world

Surprisingly, Old World ore distribution is actually the most difficult part of practicing mining. There are two reasons for this. Firstly, the location of mineral deposits between Kalimdor and the Eastern Kingdoms is very uneven. For example, between 175 and 250 it's possible to stay in 3 or 4 zones in the Eastern Kingdoms, but in Kalimdor you have to move within the same horizontal span. Secondly, the lack of flying mounts greatly increases the time required to complete mining routes around the area.

Therefore, if you are interested in quickly increasing your mining level, we recommend that you train in the Eastern Kingdoms with mining skill levels 1-275 (or 1-300).

First, find any mining trainer and learn basic mining. Before Expertise, ore veins would generate in faction-specific areas, so they would be distributed that way below.

1 – 65: Copper Ore/Copper Vein (requires Mining Level 1)

After you've collected enough mining resources, return to your trainer to learn the intermediate level.

65 – 125: Tin Ore and Silver Ore Kalimdor Silver Ore/Silver Ore (requires Mining 75) Alliance: Loch Modan and Duskwood Kalimdor (gathering silver in Kalimdor is particularly difficult, so wait until you reach It might be easier to keep collecting tin before 125)

After collecting enough ore to reach 125, you should return to the trainer and learn Advanced Mining. After this stage, all mineral points will appear in disputed areas.

125 – 175: Iron Ore and Gold Ore Kalimdor Gold Ore/Gold Vein (Requires Mining 155) Kalimdor

After completing these mining routes, you can train to expert level! When you reach expert level and start collecting Dark Iron Ore, it will be necessary for you to go to the Eastern Kingdoms, as Dark Iron Ore does not generate in Kalimdor.

175 – 275: Mithril Ore, True Silver Ore, Dark Iron Ore, Thorium Ore. Kalimdor Truesilver Ore/Truesilver Vein (Requires Mining 205) Kalimdor Dark Iron Ore/Dark Iron Vein (Requires Mining 230) Thorium Ore/Thorium Vein (Requires Mining 250) Thorium Ore, Arcane Crystal/Rich Thorium Vein (Requires Mining 275)

Once your mining level reaches 275, you can go through the dark portal and learn the Mining Master.

Outland 275 – 350: Demonic Iron Ore, Adamantite Ore

After you've mined enough sharpened iron, you'll start collecting adamantite, but there are two different veins at different levels: an adamantine-rich vein at 325 and adamantine-rich vein at 350.

Generally speaking, "rich" or "pure" points will produce more ore and have a higher chance of dropping rare minerals (in this case eternite ore). In this case, adamantine-rich veins have an additional unique advantage. After players reach 350, most people usually head to Northrend and start mining cobalt ore immediately, but this creates a lot of competition in the starting area. To circumvent this, you can continue collecting adamantine-rich ores until you reach 375 and speed up the upgrade process in WLK content.

Rich adamantine ore (350)

Whether you choose to stay in Outland or not, once you reach 350, you can head to Northrend and become a Grandmaster Miner.

Northrend 350 – 450: Cobalt Ore, Saronite Iron Ore

Cobalt Ore and Saronite also generate in rich veins. For these, they occur in relatively similar locations to standard nodes, so you can continue to make standard routes while specifically looking for them. Additionally, there is a location where pure veins of Saronite iron can be found, discussed below.

Rich Cobalt Vein (375) Saronite Ore/Saronite Vein (400), Rich Saronite Vein (425), + Pure Saronite Vein (450) Rich Saronite Vein (450) Iron Ore Vein (425) Pure Saronite Iron Ore Vein (450)

With that, you're done upgrading! congratulate! Read on to learn about Titanium Ore, Titan Steel Ingots and their potential to bring you huge profits.

Summary (Titan Iron and Titan Steel)

Regardless of whether you use the ore for crafting or not, all miners can benefit from collecting Titan Iron Ore. It is a key material in many high-level equipment. The ore is collected from Titan Iron Veins. It is most abundant in Icecrown Glacier, Sholazar Basin, and Storm Peaks, but be careful! Competition for these locations is usually fierce.

Titan iron ingots are also the main material for making Titan steel ingots. Even more so than Titanium, Titanium Steel is coveted by all professions that require bar making. Besides Saronite, it is the only mineral used in crafting ToC and ICC drawings and enchantments. It is also the primary material used in crafting coveted engineering items. To make Titansteel, you need to smelt Titansteel, which requires:

But remember: smelting has a 20-hour cooldown, so choose wisely what you do with it.

A Review Of The Processing Process Of A Mining Virus

Leave a comment , , , ,

1. A brief introduction to mining viruses

Mining viruses can be said to be "old acquaintances" in the security circle, and they have always been active in various security incidents. The "2020 Security Threat Review and Forecast" released by AsiaInfo Security shows that mining viruses will continue to be active in 2020. Not only are old viruses frequently updated, but also multiple new mining viruses have emerged. Among them, there are hidden in the scheduled tasks of Linux devices, downloading and executing mining programs and "Tsunami" backdoor programs through scheduled tasks, and launching DDoS attacks; there are also WMI fileless mining to achieve dual-platform infection; disguised as system files mining virus; and the "" fileless mining virus spread through "new coronavirus" emails.

Entering 2021, mining virus attacks against developing countries are on the rise. The reason is that countries such as India and Thailand have low investment costs in network security, relatively weak personnel security awareness, and a higher probability of successful mining virus attacks.In addition, manufacturing, government, medical, financial and other industries are still the main targets of mining viruses.

QQ Three Kingdoms Mining, QQ Three Kingdoms: Mining Resources

Leave a comment , , , ,

1. QQ Three Kingdoms: The Importance of Mining Resources

QQ Three Kingdoms is a popular mobile game that attracts countless players. In this game, mining resources is a very important part. Players with sufficient resources can improve their level and strength faster, thereby occupying a more advantageous position in the game. Therefore, mining resources has become something that many players must do in the game.

2. How to conduct resource mining

In the QQ Three Kingdoms game, resource mining is divided into two types: mineral mining and resource collection. Mining minerals needs to be done in mining areas, while gathering resources needs to be done in resource points. Different areas have different minerals and resources, and it is very important to choose the right area for mining. In addition, you need to pay attention to the refresh time of resources when mining. Only by mining in time can you obtain more resources.

3. How to improve resource mining efficiency

Improving mining efficiency allows you to obtain resources faster while also saving valuable time. Here are some ways to improve resource mining efficiency:

(1) Joining a team in the game: Joining a team in the game can increase social interaction, and at the same time, you can collaborate with each other in the team to improve mining efficiency.

(2) Use excavation props: The game provides some excavation props, such as excavation speed bonus props, resource increase props, etc. Using these props can improve excavation efficiency.

(3) Purchase VIP privileges for mining: VIP privileges in the QQ Three Kingdoms game can obtain more mining times and resources and improve mining efficiency.

(4) Choose a suitable time period for mining: Choosing a time period with fewer people to mine can reduce the number of people digging, thereby improving your personal resource acquisition efficiency.

4. Precautions

You need to pay attention to the following points when conducting resource mining:

(1) Avoid mining other people’s resource points: Resource points in the game are shared, and different people can mine them at the same time. Therefore, avoid digging into other people's resource points, otherwise it will affect the game experience.

(2) Pay attention to the safety of mining: In the QQ Three Kingdoms game, other players will attack, so you should pay attention to your own mining safety. It's best to dig in a safe area or with a teammate.

In short, in the QQ Three Kingdoms game, mining resources is a very important part. By choosing appropriate resource points and digging them, using corresponding props and efficiency-improving methods, you can obtain more resources and bring more help to your character improvement.

QQ Three Kingdoms Mining Strategy, QQ Three Kingdoms Mining Strategy Collection

Leave a comment , , , ,

During the mining process, players need to continuously perform operations, such as clicking buttons on the screen, clicking on the ground, etc. These operations will affect the results of the game. Below, the editor will bring you relevant strategies for mining in the Three Kingdoms. Interested players can quickly follow the editor to take a look!

1: How to enter the Three Kingdoms mining?

1.

In the search bar above the main interface, enter "Three Kingdoms" and click search.

2.

If the player does not find the game, he needs to open the mobile application store first, download the game, and then log in directly.

3.

On the main page after logging in, we can see the option of "General Recruitment", where we can upgrade, advance, awaken and other operations on generals to obtain higher combat effectiveness. If you want to quickly increase your combat power, you might as well choose "General Recruitment".

4.

When we are on the general recruitment page, we will see an [Activity] icon at the top of the page. At this time, we need to move the mouse to this icon and then click it. Next, the system will pop up a new window, in which we will see a [Mining]. At this time, we need to follow the prompts to operate step by step.

5.

When we enter the [Coal Mining] interface, we can see that there are many different props here, such as gold bars, copper coins, silver coins, ingots, equipment fragments, etc. The most valuable among them are gold bars. However, if you want to obtain gold bars, you need to continue fighting to obtain them, so it may be difficult for some novices. But as long as you persist, I believe you will gain a lot. Another thing to note is that after each battle is won, a large amount of experience will be rewarded, so don’t waste it~

6.

In addition to getting gold bars, we can also use various props to strengthen our weapons and armor. For example, if we are using a character with cold weapons such as a knife or a gun, we can use copper coins to strengthen it; if we are using a character with a hot weapon such as a bow or halberd, we can use silver coins to strengthen it. Of course, if you want to get more powerful equipment, you can also go to the mall to buy it. In short, as long as you use your brain more, you can get more resources!

QQ Three Kingdoms Mining (Where To Buy QQ Three Kingdoms Mining Tools)

Leave a comment ,

What are the features of the mining miners in QQ Three Kingdoms?

The QQ Three Kingdoms mining tools are mainly for technical support of the mining system. There are three main mining tools: drilling rigs, hooks and mining machines. Drilling rigs are the main mining tools that dig out rocks and collect energy resources. The hook is an important tool for mine safety protection. It can help make excavation work safer and more efficient. The mining machine is the most important mining tool in QQ Three Kingdoms. It can mine deeper and higher-grade ores and obtain more resources.

Where can I buy QQ Three Kingdoms mining tools?

QQ Three Kingdoms mining tools can be purchased through the official mall or third-party malls, such as Taobao, JD.com, etc. If you buy mining tools in the official mall, you can get official security guarantees to ensure the safety of the game; if you buy mining tools in third-party malls, you can get more favorable prices, but there are also security risks. Therefore, when players purchase mining tools, they should carefully choose the purchasing channel based on their own needs.

How to mine?

QQ Three Kingdoms mining first requires players to prepare mining tools, such as drills, hooks and mining machines. Before mining, players need to go to the mining site to select a suitable mining site, then place the mining tools at the mining site and start mining. Pay attention to safety during mining and evacuate immediately if you find a dangerous situation. After mining is completed, players can go to the official mall or third-party mall to sell and obtain resources.

Summarize

QQ Three Kingdoms mining is an interesting game activity, but it is also a job that requires technical support. When preparing to mine, players need to prepare suitable mining tools, then choose the official mall or third-party mall to purchase mining tools according to their own needs, and finally start mining, complete mining tasks, and obtain more resources and energy.

Confessions Of A Bitcoin Miner

Leave a comment , , , ,

In the world of digital currency Bitcoin, there is a mysterious type of work – "mining". As the name suggests, it is to "dig" Bitcoin like gold. People who mine Bitcoin are called "miners", and Sun Xiaoxiao (pseudonym) is a "miner".

Sun Xiaoxiao is the person in charge of a self-operated mine. Before entering the Bitcoin industry, he worked as a project manager for a certain company. After 2013, Bitcoin became popular in China, and he began to get involved in Bitcoin peripheral products, mining machine sales, Bitcoin Navigation Website. He revealed to The Paper that in the past few years of dealing with Bitcoin, although he had avoided many "pits", he still stepped on "thunders". At the most serious time, he lost all his belongings and almost had to leave. To the point of begging.

Hash collision

It all starts with mining.

The concept of Bitcoin was proposed in 2009 by an Internet geek with the pseudonym "Satoshi Nakamoto". It is a decentralized digital currency that is not issued by a specific monetary institution and is generated through a large amount of calculations based on a specific algorithm.

"It can be understood that the Bitcoin system is a huge, constantly updated ledger. Each page is called a block, and when connected in chronological order, it is called the Bitcoin blockchain. A new block is added every 10 minutes , the content inside is some transactions that occurred in the system in the past 10 minutes. Every transaction will be completely recorded in this ledger, and Bitcoin is the money recorded in the ledger." Sun Xiaoxiao explained, "In fact, our e-banking The system is also a ledger, and Alipay is also a ledger, which also records everyone’s transaction records. But the difference between Bitcoin and banks and Alipay is that Bitcoin transaction information is not stored in the central server, but is stored in all connected In computers on the Bitcoin network.”

Under Bitcoin's proof-of-work mechanism, anyone in the Bitcoin network can compete for the right to keep accounts. Whoever solves a math problem related to accounting first will be the first to keep accounts. This kind of mathematical problem has a characteristic – it is difficult to solve but easy to verify.

"Suppose the problem is to throw three dice. Whoever throws the number is less than 5. It is more difficult to throw, but the verification is very simple," Sun Xiaoxiao used an approximate example.

But the real question is not that simple. Its difficulty is equivalent to throwing 100 million dice and throwing a number less than 105,000. Whoever throws it first will get the right to keep accounts. At this time, 100,500 is a hash value. The process of throwing dice is called hash collision, and the unit of mining power is the number of hash collisions per second.

At present, the computing power of the entire Bitcoin network reaches 2.36 trillion hash collisions per second, which is equivalent to the number of water droplets in more than 200,000 50-meter-long standard swimming pools. But even with such a large amount of computing power, it takes about 10 minutes to collide with a hash value that meets the requirements.

Unit of mining power

The task of "miners" is to participate in the competition for accounting rights. They perform hash collisions 24 hours a day. This process is called "mining". The reason for this motivation is that whoever keeps the accounts will be rewarded with the newly generated Bitcoins.

But the reward for accounting is diminishing. At the beginning of Bitcoin, for every page of the ledger containing dozens of transactions generated by the system within 10 minutes, you could get 50 Bitcoins. However, according to Satoshi Nakamoto According to the algorithm, 25 rewards will be recorded on one page, and the rewards will decrease in sequence. Just like digging for gold, more will be dug at the beginning, and then less and less. Every time the new reward is reduced by half, it is called Bitcoin production halving.

Bitcoin accounting reward halving rule

In 2012, Bitcoin's output was halved for the first time. In July 2016, Bitcoin's output was halved for the second time. Currently, the reward for keeping a page of ledgers is 12.5 Bitcoins. The next halving will occur around 2020, and the total number of Bitcoins will not increase until 2040, with the total number being 21 million.

In addition to the new Bitcoins, the rewards for "miners" also include the handling fees for new ledger entries. After the total number of Bitcoins does not increase in the future, the latter will become the main income of miners.

Sun Xiaoxiao concluded that "mining" has four main functions: first, issuing new Bitcoins that can be circulated; second, confirming transactions and keeping accounts; third, adding one page to the ledger, that is, packaging transactions to form a "mine". "; Fourth, through the workload proof mechanism, the Bitcoin ledger cannot be tampered with at will.

The world's first miner is undoubtedly Satoshi Nakamoto. This block is called the "Genesis Block". Satoshi Nakamoto wrote on it "On January 3, 2009, the Chancellor of Finance was in the process of implementing the second "on the verge of a round of bank emergency aid" and used this to express dissatisfaction with the existing monetary system. The person who accepted the first Bitcoin transfer was cryptography master Hal Finney. He was also the second miner in history. In the original Bitcoin network, there were only two people, Satoshi Nakamoto and Hal Finney.

genesis block

Crazy money printing machine

"Your computer may have been a money printing machine at one time. I'm not talking about fantasy. If you had realized the value of Bitcoin when it was first born in 2009 and had easily mined a lot of Bitcoins with your own computer, If it were kept to this day, it would be a huge fortune," Sun Xiaoxiao said.

In fact, many Chinese people have become rich overnight through Bitcoin. The Paper once contacted a person who achieved financial freedom through Bitcoin. He is currently engaged in research on the underlying technology of Bitcoin – blockchain. However, due to China A large number of speculators poured into the market. He thought it was too noisy and noisy, so he chose to withdraw and was unwilling to talk about the price of Bitcoin.

In 2010, an American named Laszlo purchased 2 pizzas with 10,000 Bitcoins, which was the first commercial transaction in the history of Bitcoin. As of January 11, 2017, the price of one Bitcoin has risen to more than 6,000 yuan.

In the past, Bitcoin was very easy to "mine". It could be done by an ordinary computer CPU. You only need to download software to automatically "solve the problem". However, as the currency price rises, more and more people want to "solve problems", so every time 2016 pages of ledgers are generated, the difficulty of the questions is dynamically adjusted.

By June 2010, someone started using graphics cards for mining, bought more than 40 graphics cards, and built a mine in Tianjin. However, due to lack of timely maintenance, it was shut down before many Bitcoins were mined, and it was shut down at a loss.

Later, graphics cards gradually became unable to solve problems, and personal "mining" became less and less advantageous, so the "mining pool" was invented.

"The 'mining pool' collects everyone's computing power, and if they win, everyone shares the profits, just like a game group," Sun Xiaoxiao said.

More energy-saving mining tools were soon invented. "Pumpkin Zhang", a doctoral student in the Department of Computer Science at Beihang University, began to make money by selling equipment. The efficiency of his mining machine chip Avalon is equivalent to hundreds of computers. In September 2012, Pre-orders will be accepted starting this month, and shipments will begin in the first quarter of 2013.

At that time, there was an economic crisis in Cyprus, the price of Bitcoin rose to a historical high of $266, and the market was booming. "Assembling a mining machine is like assembling a money printing machine." A group of people spent 8,000 yuan to buy the first three batches of 1,500 mining machines from "Pumpkin Zhang" and "made a lot of money."

But a "deep pit" in the history of mining began to appear. A company bought Avalon chips and assembled them. It claimed to pay back the money in 3 months, but in fact it was impossible to pay back the money because it was selling futures mining machines—— Pay the money first and get the mining machine a few months later. Because it did not receive the Avalon chip in time, the company delayed production. In the mining industry where "time is life", users who ordered mining machines basically cannot get back their money.

However, due to the impact of this mining machine, the difficulty of "mining" rose very quickly at that time. Those who could mine one coin a day in the past could only mine 0.8 coins a day.

Bitcoin stocks hit zero

"I almost jumped into this pit, but I was smart enough to avoid it and jumped into another pit," Sun Xiaoxiao was referring to the most famous Roast Cat mining machine in the Bitcoin circle.

In August 2012, a person with the pseudonym "Roasted Cat" posted on the Bitcoin forum that he would conduct an IPO on the Bitcoin stock exchange GLBSE. He had established a company and issued 400,000 shares, which were expected to be held by the public. 40%, Shenzhen Bitquan Information Technology Co., Ltd. holds 60% of the shares, and the original share price is 0.1 Bitcoin (0.1B) per share. The company spent approximately 2 million yuan to produce the first-generation roasted cat mining machine.

“In fact, we can’t say that Roast Cat is a trap, because it really made mining machines and mass-produced many mining machines. It earned a lot of Bitcoins by mining and selling mining machines, and the dividends to shareholders were very considerable. At the time of the IPO 0.1B, and later the stock price increased 50 times, suddenly becoming 5B, and the price of a coin increased from dozens to hundreds of yuan, creating many rich people," Sun Xiaoxiao said.

When Sun Xiaoxiao's stock price of BBQ was 2B, he bought all the money in Bitcoin, and then bought all the coins into BBQ stocks. His idea at the time was: the dividends of the BBQ stocks he held and The currency price is enough to support all daily expenses. Whether the stock price rises or the currency price does not rise, or vice versa, I can maintain a normal life. "If both of them rise, I will be happy."

However, after Bitcoin experienced a skyrocketing surge at the end of 2013, both the stock price and the currency price of Roast Cat plummeted, but Sun Xiaoxiao still held on to a glimmer of hope because a new generation of Roast Cat mining machines was about to be launched. But in fact, the mining machines of Bitmain, the later Bitcoin mining giant, also began to quickly occupy the market.

In May 2014, before Bitcoin Mainland’s Ant Mining Machine was launched, Sun Xiaoxiao got the opportunity to go to Shenzhen to help Roast Cat sell mining machines. “I accepted it without hesitation because I felt it was helping shareholders. Make money." However, sales in Shenzhen did not go very smoothly, and Sun Xiaoxiao later left the team. At that time, his good friend "Lightning" repeatedly advised him to sell the stock, but he chose to hold it because he had the illusion in his heart that Roasted Cat would make a comeback. Unfortunately, God failed to fulfill his wishes. In 2015, Roast Cat lost contact, and Sun Xiaoxiao’s stocks returned to zero.

"You must learn to get off the car. Getting off the car can save your life," Sun Xiaoxiao concluded.

speed of life and death

China has the largest Bitcoin transaction volume, the largest number of mining operations, and the largest number of large mines and mining pools, and the latter is determined by cost. Sun Xiaoxiao said that many of the top mining pools are in China, and the computing power of these mining pools accounts for about 70% of the entire network.

The Bitcoin computing power of the mine that Sun Xiaoxiao is responsible for is more than 100P, accounting for 6% of the total computing power of the global Bitcoin network. In other words, for every 100 Bitcoins generated by the Bitcoin network, 6 are mined by Sun Xiaoxiao’s team, and about 100 Bitcoins can be mined in a day. Calculated based on the price of 6,000 yuan per Bitcoin, these Bitcoins are probably worth close to 600,000 yuan. Calculated based on the price of 0.35 yuan per kilowatt-hour of electricity, using an Antminer S7 mining machine to dig out each coin costs more than 3,000 yuan.

Sun Xiaoxiao’s mine currently consumes 40,000 kWh of electricity per hour. According to mainstream computing power, global mines now consume more than 600,000 kilowatt-hours of electricity per hour and 5.2 billion kilowatt-hours per year.

“Some people say that mining Bitcoin consumes too much electricity and is completely meaningless. However, the current market value of the Bitcoin system is more than 10 billion U.S. dollars. Based on the current Bitcoin price, the market value of newly mined Bitcoins every year is 600 million U.S. dollars. Above, in addition, Bitcoin mining solves the problem of power abandonment. China abandoned 50 billion kilowatt hours of electricity in 2015. Currently, many large mines are in China. Our mines are in Tibet and Sichuan, which solves many local water and electricity abandonments. "Sun Xiaoxiao believes that his job is to "solve with one network cable" the problem of excess energy that cannot be consumed in many areas. "Solve it on the spot, convert it into Bitcoin, and transmit the value to the world, saving even the cost of laying the power grid. "

Real mining is very thrilling.

Since mines consume a lot of electricity, they are generally built next to reservoirs that generate electricity, and this must be adjusted according to the season.

Because there is a big difference in electricity prices between Sichuan's wet season and dry season, during the Dragon Boat Festival in 2015, Sun Xiaoxiao's team moved 0.3% of the network's total computing power from Inner Mongolia to Sichuan, and also moved the mining machines there during the dry season. In Inner Mongolia and Xinjiang, "it's a bit similar to raising bees and grazing."

Every time the computing power is moved, it is like a "war". It needs to be transported by air to grab time. All the computing power needs to be deployed within 48 hours. This is not only to complete the placement of the equipment, but also to complete all the links and set up the mining machines. parameters to make it run normally. This is because when the mining difficulty rises the most, if it is a little slower, the income will be completely different from if it is a little faster.

"In martial arts, the only thing that matters is speed. You must deploy computing power quickly, otherwise others behind you will not be able to catch up. Roasted Cat lost to Antminer in the competition because it did not bring its third-generation mining machine to the market in time," Sun said. Xiaoxiao said one of his secrets is "fast".

On one trip to Sichuan, Sun Xiaoxiao and his party encountered a rockfall. "If we had passed here a few minutes earlier, we might not be alive."

Sun Xiaoxiao personally believes that now is not the best time for mining. Because the best time was between 2009 and 2012, when 50% of Bitcoins were mined; the second best time was from 2012 to 2016, when 25% was mined in these four years; and the third best time was only From 2016 to 2020, 12.5% ​​of Bitcoins can be mined.

He believes that the mining industry will always exist, but the recovery period is getting longer and longer. “In the future, mining will be highly intensive, super-large mines will be built, and the division of labor will be more refined, including manufacturing mining machines and mining machines. Everyone will do what they are best at when it comes to operating and selling computing power, while ordinary people will participate in mining through computing power securities and standard computing power exchanges.”

As for the behavior of speculating in currencies, Sun Xiaoxiao told The Paper, “You can speculate if you are willing to do so at your own risk.”
