Application-Specific Integrated Circuit (ASIC) Miner

Description: An application-specific integrated circuit (ASIC) is a type of circuit that has been designed for a single specific purpose. An ASIC miner refers to a device that uses microprocessors for the sole purpose of "mining" digital currency. Generally, each ASIC miner is constructed to mine a specific digital currency. So, a bitcoin ASIC miner can mine only bitcoin. One way to think about bitcoin ASICs is as specialized bitcoin mining computers, or “bitcoin generators," that are optimized to solve the mining algorithm.     Developing and manufacturing ASICs as mining devices is costly and complex. Because ASICs are built especially for mining cryptocurrency, they do the job faster than less powerful computers. ASIC chips for cryptocurrency mining have become increasingly efficient, with the latest generation operating at around just 29.5 Joules per Terahash.     Understanding Application-Specific Integrated Circuit (ASIC) Miners     Instead of being general-purpose integrated circuits—like RAM chips or PC or mobile device microprocessors—ASICs employed in cryptocurrency mining are specific integrated circuits designed solely to maintain the bitcoin blockchain—a public shared database that stores digital information.     Originally, bitcoin’s creator intended for bitcoin to be mined on central processing units (CPUs)—your laptop or desktop computer. However, bitcoin ASICs surpassed both CPUs and graphics processing units (GPUs) in terms of their reduced electricity consumption and greater computing capacity. After first gaining traction in mid-2013 when other hardware mining devices started hitting their bottlenecks in mining, Bitcoin ASIC miners have retained their lead.     Bitmain Confirms Halting Its Shipment of Antminers to Chinese Customers     Bitmain, one of the world’s largest manufacturers of bitcoin mining machines, confirmed it will halt shipping Antminers to mainland China.     “From October 11, 2021, Antminer will stop shipping to mainland China (excluding Hong Kong and Taiwan),” according to a statement from Bitmain’s official WeChat account. The move doesn’t affect Bitmain’s overseas customers and the company said that it has increased the supply of Antbox to speed up the construction of overseas mines.     On Sept. 28 CoinDesk cited three sources who said that Bitmain was planning to suspend sales of its machines to miners in mainland China, after the sweeping ban on crypto activity imposed by the country’s government.     China’s crackdown on the crypto industry has created an opportunity for the miners outside of the region to participate in the sector, resulting in a recovery in bitcoin network’s hashrate, or computing power, which is a key gauge of mining activity.     What's inside a WhatsMiner? Disassembling a Bitcoin ASIC     In early December of last year, mining machine manufacturer MicroBT announced the parameters of the WhatsMiner M30 series, indicating that the power consumption ratio of the entire series of bitcoin mining rigs would be lower than 50W/T, which caused concern among cryptocurrency mining practitioners.  In mid-May this year, Bitcoin will usher in the third halving of its block subsidy in history, also regarded as a critical period for the computing power of the entire Bitcoin network. Miners are also updating their equipment for the arrival of the halving.     In the current epidemic situation, miners and people in the entire cryptocurrency industry are in a difficult winter period. At this difficult time, MicroBT hopes to spend the time with users and stick to their beliefs. At 10:30 p.m. EDT on April 16, 2020 MicroBT will hold the Global WhatsMiner M30 Launch Event to explain in detail the full lineup of the M30 series products and sales strategies.     In the current epidemic situation, the online event can break the shackles of physical space by going digital and delivering the latest news of the M30 launch efficiently. Since MicroBT announced the news of the new product launch of the WhatsMiner M30 series, it has aroused concern among peers in the mining and blockchain industries. Therefore, MicroBT has also been sharing the latest news through its twitter and telegram group.     In addition to the official community, MicroBT is also accelerating the expansion and improvement of the company's internal and external business. MicroBT is expanding in overseas markets and improving the quality of after-sales services. It has officially established a cooperation with HMTech which has become the first after-sales partner of WhatsMiner in North America. In terms of user operations, Jorden Chen, who is experienced in traditional industry operations, serves as the COO of MicroBT, bringing mature management and operational experience to the emerging bitcoin mining industry, which has enabled MicroBT's business operations and customer service capacity to grow rapidly.     What Is Bitcoin Mining?     Bitcoin mining is the process by which new bitcoins are entered into circulation; it is also the way that new transactions are confirmed by the network and a critical component of the maintenance and development of the blockchain ledger. "Mining" is performed using sophisticated hardware that solves an extremely complex computational math problem. The first computer to find the solution to the problem is awarded the next block of bitcoins and the process begins again.     Cryptocurrency mining is painstaking, costly, and only sporadically rewarding. Nonetheless, mining has a magnetic appeal for many investors interested in cryptocurrency because of the fact that miners are rewarded for their work with crypto tokens. This may be because entrepreneurial types see mining as pennies from heaven, like California gold prospectors in 1849. And if you are technologically inclined, why not do it?     However, before you invest the time and equipment, read this explainer to see whether mining is really for you. We will focus primarily on Bitcoin (throughout, we'll use "Bitcoin" when referring to the network or the cryptocurrency as a concept, and "bitcoin" when we're referring to a quantity of individual tokens).     A New Gold Rush     The primary draw for many mining is the prospect of being rewarded with Bitcoin. That said, you certainly don't have to be a miner to own cryptocurrency tokens. You can also buy cryptocurrencies using fiat currency; you can trade it on an exchange like Bitstamp using another crypto (as an example, using Ethereum or NEO to buy Bitcoin); you even can earn it by shopping, publishing blog posts on platforms that pay users in cryptocurrency, or even set up interest-earning crypto accounts.     An example of a crypto blog platform is Steemit, which is kind of like Medium except that users can reward bloggers by paying them in a proprietary cryptocurrency called STEEM. STEEM can then be traded elsewhere for Bitcoin.     The Bitcoin reward that miners receive is an incentive that motivates people to assist in the primary purpose of mining: to legitimize and monitor Bitcoin transactions, ensuring their validity. Because these responsibilities are spread among many users all over the world, Bitcoin is a "decentralized" cryptocurrency, or one that does not rely on any central authority like a central bank or government to oversee its regulation.     Mining to Prevent Double Spend     Avalon miner is getting paid for their work as auditors. They are doing the work of verifying the legitimacy of Bitcoin transactions. This convention is meant to keep Bitcoin users honest and was conceived by Bitcoin's founder, by verifying transactions, miners are helping to prevent the "double-spending problem."     Double spending is a scenario in which a Bitcoin owner illicitly spends the same bitcoin twice. With physical currency, this isn't an issue: once you hand someone a $20 bill to buy a bottle of vodka, you no longer have it, so there's no danger you could use that same $20 bill to buy lotto tickets next door. While there is the possibility of counterfeit cash being made, it is not exactly the same as literally spending the same dollar twice. With digital currency, however, as the Investopedia dictionary explains, "there is a risk that the holder could make a copy of the digital token and send it to a merchant or another party while retaining the original."     Mining and Bitcoin Circulation     In addition to lining the pockets of miners and supporting the Bitcoin ecosystem, mining serves another vital purpose: It is the only way to release new cryptocurrency into circulation. In other words, miners are basically "minting" currency. For example, as of September 2021, there were around 18.82 million bitcoins in circulation, out of an ultimate total of 21 million.     Aside from the coins minted via the genesis block (the very first block, which was created by founder Satoshi Nakamoto), every single one of those bitcoins came into being because of miners. In the absence of miners, Bitcoin as a network would still exist and be usable, but there would never be any additional bitcoin. However, because the rate of bitcoin "mined" is reduced over time, the final bitcoin won't be circulated until around the year 2140. This does not mean that transactions will cease to be verified. Miners will continue to verify transactions and will be paid in fees for doing so in order to keep the integrity of Bitcoin's network.     Aside from the short-term Bitcoin payoff, being a coin miner can give you "voting" power when changes are proposed in the Bitcoin network protocol. This is known as a BIP (Bitcoin Improvement Protocol). In other words, miners have some degree of influence on the decision-making process on such matters as forking.     What You Need to Mine Bitcoins     Although early on in Bitcoin's history individuals may have been able to compete for blocks with a regular at-home personal computer, this is no longer the case. The reason for this is that the difficulty of mining Bitcoin changes over time.     In order to ensure the smooth functioning of the blockchain and its ability to process and verify transactions, the Bitcoin network aims to have one block produced every 10 minutes or so. However, if there are one million mining rigs competing to solve the hash problem, they'll likely reach a solution faster than a scenario in which 10 mining rigs are working on the same problem. For that reason, Bitcoin is designed to evaluate and adjust the difficulty of mining every 2,016 blocks, or roughly every two weeks.1     When there is more computing power collectively working to mine for bitcoins, the difficulty level of mining increases in order to keep block production at a stable rate. Less computing power means the difficulty level decreases. At today's network size, a personal computer mining for bitcoin will almost certainly find nothing.     All of this is to say that, in order to mine competitively, miners must now invest in powerful computer equipment like a GPU (graphics processing unit) or, more realistically, an application-specific integrated circuit (ASIC). These can run from $500 to the tens of thousands. Some miners—particularly Ethereum miners—buy individual graphics cards (GPUs) as a low-cost way to cobble together mining operations.

How the Baseball Cap Went From Athletic Gear to Fashion Statement

Description: The “Philadelphia style,” with a sturdier brim, debuted in 1908, and was quickly embraced by major-league teams. Designers continued to tinker, as crowns grew higher and materials became sturdier. The advent of television—the first major-league game was telecast on August 26, 1939—brought a whole new audience to the sport and precipitated a rush of uniform redesigns and team relocations. By 1945 every team was wearing its own branded hat, and the accessory soon threaded its way into the hearts of children, especially those who played Little League and would take the look into adulthood.     In the 1960s and ’70s, agricultural companies began embellishing their foam-front hats with company logos and cheap, plastic adjustable straps. Mesh backing also made the hats more breathable for workers, and long-haul drivers embraced these new accessories, inaugurating the phenomenon of the trucker hat.     In the 1980s, New Era, the company that had supplied Major League Baseball for decades, started selling authentic team-branded hats to fans. Soon they were de rigueur. Tom Selleck’s character in “Magnum, P.I.,” set in Hawaii, wore a Tigers hat. You could see baseball hats on the cover of French Elle, in rap videos and atop the head of Princess Diana, whose occasional appearance in jeans and a baseball cap helped nurture her reputation as the “people’s princess”: It signaled approachability, even for a royal. And it worked for other luminaries as well. Steve Reich, a composer whose work has been played in some of the grandest halls in the world, and Paul Simon, one of the most successful pop musicians of the last 50 years, are both inseparable from rumpled, unbranded caps, even when they’re wearing black tie. No stuffy art-world or rock-star glamour here, the hats say. These are millionaires you could have a beer with.     The Advantages of a Snapback Cap     Adjustable Hats Fit Better     There is one problem that many people have with fitted caps, and this is that they do not always fit very well. They are either a bit too loose, or a bit too tight, and the next size up or down is way too loose or tight. The caps that come in small, medium and large are just not always right for everyone. With a snapback, you can adjust it so that it is a perfect fit, which is going to make your hat really comfortable too. Adjustable hats are easy to adjust, and can be fitted to many different sizes quickly and easily. There are no buckles to jab into the back of your head or straps hanging out, and no Velcro for your hair to get caught up in.     Show Your Team Spirit     When people go to sporting events, they often wear clothing with the logos of their favorite teams to show their support. One great way to show your team spirit is to wear a snapback tap with the team logo on it. It is a lot less expensive to get a hat than other sports-related clothing items, such as jackets and shirts, and unlike these pieces of clothing, you can wear the same hat every day if you want, and no one is going to notice or even care. If you were to wear a team shirt every day, people will notice, so a hat is a much better way to be able to show your team spirit whenever you feel like it.     Great Gifts     If you are looking for a fun gift that will not cost a lot of money, an adjustable baseball cap is the ideal gift. If you have a sports enthusiast in your family, they will love getting a hat that has their favorite team's logo on it. The best part is, with a snapback cap, you never have to worry about whether or not you have gotten the right size, because it can be adjusted to just about any size.     Trucker Caps Let Israelis Stand Out, but Not Too Much     TEL AVIV—A craze for trucker cap in Israel this year is allowing people here to finally express themselves sartorially—and at the same time look just like everyone else.     Israelis have an easy-going fashion sense that doesn’t much stick out in a crowd. Thanks to the lasting influence of the state’s founding socialist ethos, many avoid bold fashion statements. Among the nonreligious, plain T-shirts with jeans, or shorts when it’s hot, are the most common uniform. High-powered CEOs shun suits. The fanciest restaurants rarely have a dress code.     ut the mania for the caps—preferably with an animal on the front—is giving Israelis an opportunity to express themselves, up to a point.     Made by San Francisco-based hat maker Goorin Bros., the hats come embossed with different animals, often accompanied by a play on words. People choose which one they wear to offer a hint as to their personality.     “It’s a hat with a presence,” said Amit Deutsch, a 36-year-old Tel Avivi, who sported a cap with a black panther, and had bought five of them at 150 Israeli shekels, or $46. “It’s become a type of icon.”     Hodaya Elkayam, 23, who purchased a blue suede cap with an eagle and the word “America” in a Tel Aviv market on a sunny Friday afternoon, said the hats “have got style, they’re pretty and comfortable. So they’re good for all occasions.”     RESERVED FOR PEOPLE WHO ARE NOT BLENDING IN     In HBO Max's abortion road trip movie Unpregnant, Simonelli introduces Barbie Ferreira's character, Bailey — who's all of the above — wearing a purple angora Kangol bucket hat as she pops up over a bathroom stall divider. The hat's unexpected color and plushness, which match and clash with her shaggy green stuffed animal backpack, also help convey Bailey's innate but unintentional style. "I don't know if she's registered the cool factor that she has," adds Simonelli. Plus, her face-framing headwear was actually inspired by Ferreira serving her own outfit inspo in a textured white variation on Instagram.     A nostalgic look back at the bucket hat icons of decades past really does run the gamut of individual style and creative talents. Simonelli references late-'80s hip-hop legends Run-DMC, the white cotton canvas classic of author and founder of the '70s gonzo journalism movement Hunter S. Thompson, and, of course, all the floppy and floral-accented toppers worn by Mayim Bialik in Blossom, which ran from 1990 to 1995.     "Then you think of some of the late-'80s and '90s R&B singers, like Brandy, SWV, Missy Elliot, and Janet Jackson," says Smith, who also name-checked Blossom. "That cool sense of style that's laid-back and chill." During the early-2000s return of carefree teen pop, a trifecta of Mandy Moore, Jessica Simpson, and Britney Spears in the relaxed look, also come to mind.     All About Knitted Hats     Who knows when the first person decided to put something over their head to keep it warm, but knitters know that knitted hat is some of the most fun and easy things to knit.     When they’re worked in the round there is little in the way of shaping, except when you get to the crown.     Most hats are worked from the bottom up, with stitches cast-on and worked in a snug stitch pattern such as ribbing, or in stockinette for a rolled bring hat, using a smaller size needle than is used for the head portion of the hat.     In many hat patterns, the hat is worked straight for the desired length of the crown, then nearly all of the stitches are evenly decreased over the course of just a few rounds.     The yarn is cut, the tail threaded through the remaining stitches, pulled tight, and fastened off to the inside of the hat.     The hat can be topped with a pom pom, i-cord, tassel, or whatever embellishment strikes your fancy.     A great book for learning to make hats is Ann Budd’s Handy Book of Patterns, from which some of the material on this page is excerpted. There are chapters on basic hats as well as the type of hats called “tams.”     There are several types of hats, but the most popular knitted hats are beanie-type caps, tams (sometimes called “berets”), slouch hats, earflap hats, and tuques.     Beanies: These hats can be super simple or dressed up with a lace or cable patterns. In cooler climates, they’re wonderful gifts for knitters to make.     Tams/Berets: There are so many different stitch patterns to use in this style. Tams and berets can be plain stockinette or intricate Fair Isle. This style of hat is really flattering on just about every face shape, too.     Earflap Hats: These hats are popular in cold climates. They’re great for keeping ears warm and they’re fun to knit. The knitters of Peru specialize in these hats, as shown in the photo at right.     THE HISTORY OF THE STRAW HAT     Reaching for a straw hat to complete our seaside look—or frankly, any summer outfit—is as instinctive to us as say, oh I don’t know, breathing. Next to sunglasses, it’s one of the most obvious accessories to use as protection against the sun’s harmful UV rays, but its origins are less than clear. When an item is as ubiquitous as that of a straw hat, it’s virtually impossible to determine its original maker or even pinpoint the first documentation of its existence. (Fun fact about hats: Historians believe that some type of head-covering piece—as protection against inclement weather—was the first article of clothing ever worn by humans.)     Straw hats—distinguished by their woven makeup of different types of straw or fibers similar in texture and strength, like braided hemp, raffia, and jute—are believed to have been worn in Europe and Asia as early as the 15th century (after the Middle Ages). In most countries in Asia, including Japan, China, Indonesia, Malaysia, and Vietnam, rice paddy workers topped their heads with conical-shaped hats to shield themselves from the sun and the rain, though legend in Vietnam has it that the hat, or nón lá in Vietnamese, originated from when a goddess descended from the sky wearing an enormous hat made of four large leaves held together by bamboo sticks, which protected the people from a torrential downpour.     In the Très Riches Heures du Duc de Berry, the most famous surviving example of an illuminated French Gothic manuscript created from 1412 to 1416, short-brim straw hats are shown mostly worn by men. Though by the 1700s, French women wore straw bonnets and in the 1800s, European paintings all depict women posing for portraits in ribbon-adorned floppy straw hats and floral-strewn ones with an upturned brim. Vincent Van Gogh even immortalized his straw hat in a self-portrait in 1887. The first cowboy hat—made of straw, might we add—was invented by John B. Stetson in 1865, and the silhouette basically remains unchanged to this day.     By the late 1800s and early 1900s, straw hats were embraced by everyone. But it wasn’t until President Theodore Roosevelt’s 1906 visit to the Panama Canal—when he was photographed at the construction site in his pale suit and Panama hat—that the accessory catapulted to fame. Light in weight, the summertime staple exuded equal parts casual and polish; by 1944, it became Ecuador’s number-one export.     Conclusion     As an experienced manufacturer and supplier, in addition to the above hats, we also provide various other types of caps and hats, such as children's baseball cap,knitted hats, straw hats and so on.
