Why Quebec is betting big on Bitcoin


Downpours transform the mottled landscape into lush emerald, while azaleas bloom and migrating cranes and storks begin the long journey back north. The rainfall also brings trucks stacked with computers to hydropower dams, where entrepreneurs can tap cheap electricity for mining bitcoin—the arcane process that accumulates the cryptocurrency using huge amounts of computing power to solve equations. Cryptocurrency mining requires huge amounts of computing power, making energy consumption a major overhead for the industry.

Local governments will often offer power for pennies—or even free—to attract jobs and get a painless boost to their gross domestic product figures.

While individual miners and traders may be able to slip through the cracks, larger commercial miners will likely be considering alternative mining hubs with less rigorous regulatory regimes, analysts say. Last week, a number of companies involved in cryptocurrency mining began halting operations in China.

Jiang Zhuoer, chief executive of BTC. Before the crackdown, bitcoin mining in China was projected to generate more than million metric tons of carbon emissions by , according to a study published in scientific journal Nature Communications. If the global bitcoin mining industry were a country, it would be the 29th biggest consumer of power in the world on a list of nations by energy use, above Argentina, which has a population of roughly 45 million.

Mining rigs are driven thousands of miles across China to the belching power stations of Inner Mongolia or Xinjiang province. While most crypto mining operations in China could be considered legal grey areas, some are outright illegal, says Tang. Bitcoin miners are essentially paid to work as auditors, verifying the legitimacy of transactions, while allowing a trickle of new units of the currency into the economy. And when miners earned cryptocurrencies, they had to exchange them covertly as private individuals, usually overseas.

This incongruity has become stark: scores of tech companies with plush offices in Shenzhen and Shanghai purport to be engaged in artificial intelligence, big data processing, or blockchain for commercial use, but in reality they earn their money from crypto mining at faraway dams and power plants.

Crackdowns have happened before. Back on Sept. A high concentration of mining activity in one country threatens the entire system that underpins cryptocurrencies. Vulnerabilities arise when so much mining capacity is concentrated in one place.

One of the core security pillars of the blockchain technology upon which cryptocurrencies operate is that transactions are transparent and publicly verifiable. But what if a large proportion of bitcoin miners—perhaps ordered by a government—together decided to manipulate a ledger in a particular way?

This could potentially trigger a fork in bitcoin, or at least sow sufficient uncertainty to roil the market. That is a concern. In regions where power supplies are unstable, the amount of energy required for mining can also be problematic. In Iran, blackouts and power shortages prompted the government to ban crypto mining on May Before the recent crackdown, efforts were being made to clean up the bitcoin mining industry.

As well as consuming an enormous amount of power, mining rigs generate a whopping amount of heat and need to be cooled by fans which, in turn, use more energy. Technological advancements, such as liquid cooling for computers, can help reduce power consumption.

In more ambitious plans, some towns in Xinjiang province have been experimenting with using the high temperatures produced by mining rigs to provide heat to the community. But the impact of crypto mining goes beyond climate. The surging price of bitcoin before the crackdown encouraged the tech-savvy across China to turn computers otherwise used for artificial intelligence or big data crunching to mining operations. The resulting rise in demand for fossil fuels prompted some coal miners to restart mothballed mines without official approval, leading to a spike in deadly accidents, according to Al Jazeera.

In an effort to reduce power consumption, Inner Mongolia last week issued draft guidelines to curb crypto mining by withdrawing preferential policies for big data centers and cloud computing firms, while announcing that telecommunication companies, internet firms and even internet cafes would have their business licenses revoked if they engaged with crypto mining.

The local government has even set up a new hotline so citizens can report suspected mining operations. Analysts say that the regulatory crackdown will likely prompt big commercial mining operations to flee China en masse for alternative hosts, such as Mongolia, Kazakhstan and Afghanistan.

Of all the potential implications of blockchain for the energy sector, the energy use of cryptocurrencies — and bitcoin in particular — has captured the most interest. With bitcoin value tripling in recent months and Facebook announcing its new Libra coin, interest in the energy use of cryptocurrencies is again on the rise. In this commentary, we explain why and how bitcoin uses energy; dig into published estimates of bitcoin energy use and provide our own analysis; and discuss how these trends might evolve in the coming years. In order to understand why and how bitcoin uses energy, we first need to understand its underlying technology: blockchain. Blockchain offers a new way to conduct and record transactions, like sending money.

Other cryptocurrencies have, too, seen similar surges and dips in value. While buying on an exchange like Coinbase is usually fairly simple and allows you to buy fractions of cryptocurrencies, there are those who prefer to mine their coins.

How to build a cryptomining rig: Bitcoin mining 101

Ten agencies, including the central bank, financial, securities and foreign exchange regulators, vowed to work together to root out "illegal" cryptocurrency activity, the first time the Beijing-based regulators have joined forces to explicitly ban all cryptocurrency-related activity. Explainer: What's new in China's crackdown on crypto? China in May banned financial institutions and payment companies from providing services related to cryptocurrency transactions, and issued similar bans in and The repeated prohibitions highlight the challenge of closing loopholes and identifying bitcoin-related transactions, though banks and payment firms say they support the effort. Friday's statement is the most detailed and expansive yet from the country's main regulators, underscoring Beijing's commitment to suffocating the Chinese crypto market. The move comes amid a global cryptocurrency crackdown as governments from Asia to the United States fret that privately operated highly volatile digital currencies could undermine their control of the financial and monetary systems, increase systemic risk, promote financial crime and hurt investors.

The Bitcoin network is burning a large amount of energy for mining. In this paper, we estimate the lower bound for the global mining energy cost for a period of 10 years from to , taking into account changes in energy costs, improvements in hashing technologies and hashing activity. We estimate energy cost for Bitcoin mining using two methods: Brent Crude oil prices as a global standard and regional industrial electricity prices weighted by the share of hashing activity. Despite a billion-fold increase in hashing activity and a million-fold increase in total energy consumption, we find the cost relative to the volume of transactions has not increased nor decreased since

The main problem with a distributed transaction log is how to avoid inconsistencies that could allow someone to spend the same bitcoins twice. The solution in Bitcoin is to mine the outstanding transactions into a block of transactions approximately every 10 minutes, which makes them official. Conflicting or invalid transactions aren't allowed into a block, so the double spend problem is avoided. Although mining transactions into blocks avoid double-spending, it raises new problems: What stops people from randomly mining blocks? How do you decide who gets to mine a block? How does the network agree on which blocks are valid? Solving those problems is the key innovation of Bitcoin: mining is made very, very difficult, a technique called proof-of-work.
