France 24 is not responsible for the content of external websites. On a factory floor in Caracas, the din of dozens of computers working non-stop is deafening. This is the sound of a bitcoin mine -- one of several in a country where cheap electricity has made crypto mining a rare profitable endeavor. The electricity bill for all this? In a country in recession and contending with the world's highest inflation of nearly 3, percent in , crypto mining presents an economic opportunity for a lucky few.

How one of South America’s biggest dams became a Bitcoin battleground
Mining for bitcoins creates a large computational demand. The much-hyped technology behind Bitcoin, known as blockchain, has intoxicated investors around the world and is now making tentative inroads into science, spurred by broad promises that it can transform key elements of the research enterprise.
Supporters say that it could enhance reproducibility and the peer review process by creating incorruptible data trails and securely recording publication decisions. But some also argue that the buzz surrounding blockchain often exceeds reality and that introducing the approach into science could prove expensive and introduce ethical problems. A few collaborations, including Scienceroot and Pluto , are already developing pilot projects for science.
It plans to raise the funds in early by exchanging some of the science tokens it uses for payment for another digital currency known as ether. And the Wolfram Mathematica algebra program — which is widely used by researchers — is currently working towards offering support for an open-source blockchain platform called Multichain.
Scientists could use this, for example, to upload data to a shared, open workspace that isn't controlled by any specific party, according to Multichain.
As one sign of this trend, consulting firm Deloitte has identified more than 24, aborted, largely financial, blockchain projects on the GitHub software-development platform in alone. Yet Hamilton still says blockchain has incredible potential. The victor of this contest adds an encrypted block of transactions to the chain and earns a financial reward. They communicate the extended blockchain to all the other miners, and the process starts again.
Mining takes a lot of computation, which makes it unlikely that any individual will win twice in a row. This is crucial, because if miners could add more than one block, they could gain power over the record and even discard earlier blocks they had added. That would effectively refund their transactions and enable them to spend the same bitcoins again. In , a consortium of miners highlighted that vulnerability by working together to add multiple blocks, although the group voluntarily disbanded once they came close to achieving it.
One way blockchain technology could help scientists is by reliably collecting and preserving data concerning research activities. This would make it easier to reproduce results in cases where published accounts insufficiently explain methodologies, according to Joris van Rossum, director of special projects at Digital Science, a research-technology firm in London.
And open blockchains would generate information such as how frequently researchers collect measurements, enabling people to look beyond metrics such as publications and citations, he says 1. Greenspan says that such currency-style blockchains are unsuitable as scientific archives, because recording each transaction incurs a financial cost, which can easily add up.
Costs in research applications would increase faster than it does for cryptocurrencies because modern science produces far more data. This also lowers power consumption. Claudia Pagliari, who researches digital health-tracking technologies at the University of Edinburgh, UK, says that she recognizes the potential of blockchain, but researchers have yet to properly explore its ethical issues.
What happens if a patient withdraws consent for a trial that is immutably recorded on a blockchain? And unscrupulous researchers could still add fake data to a blockchain, even if the process is so open that everyone can see who adds it, says Pagliari. Once added, no-one can change that information, although it's possible they could label it as retracted. Google Scholar. Download references.

How Bitcoin’s footprint is impacting water use
In little over a decade, bitcoin has risen from a fringe technology popular with cryptographers, to the world's ninth most valuable asset by market cap. The cryptocurrency 's dramatic ascent has created millionaires, reimagined money, and launched a multi-billion dollar industry inspired by its revolutionary decentralised technology. But it has also brought with it some unwanted side effects. The computing power required to support bitcoin's underlying network now requires nearly as much energy as the entire country of Argentina, leading to criticism about its environmental footprint. Analysis by the University of Cambridge suggests the bitcoin network uses more than terawatt-hours TWh annually, which would rank it in the top 30 electricity consumers worldwide if it were a country.
Correction: Bitcoin-Carbon Footprint story

Because some bitcoin investors have become millionaires overnight, more and more people are intrigued by the possibility of striking it rich through investing in cryptocurrencies like Bitcoin. A cryptocurrency is a virtual medium of exchange that exists only electronically; it has no physical counterpart such as a coin or dollar bill, and no money has been staked to start it. Cryptocurrencies are decentralized, meaning that there is no central authority like a bank or government to regulate them. The advantage of this is that there are no transaction fees, anyone can use it, and it makes transactions like sending money across national borders simpler. While transactions are tracked, the people making them remain anonymous.
The debate about cryptocurrency and energy consumption
In a financial world of stocks, bonds, foreign exchange, and credit cards, trillions of dollars are traded daily, with money flows handled by a bevy of databanks. In the world of cryptocurrency, billions of dollars worth of Bitcoin are traded through as many as , transactions per day, consuming the energy supply of a modernized country. Tristan Rayner explores. The cryptocurrency Bitcoin is close to using around 0.
How to generate your very own Bitcoin private key
Unrest in the central Asian country — the second-largest centre for mining of the cryptocurrency — led to an internet blackout. Bitcoin took a hit on Thursday after the internet in Kazakhstan was shut down amid intensifying violence. The central Asian nation in recent days has been rocked by violent clashes between protesters, police and the army. The protests began in the west of the country over the weekend, after a sharp rise in fuel prices, and quickly spread through cities across the nation. The internet was shut down nationwide on Wednesday.
Bitcoin more powerful than fastest supercomputers
Burning for Bitcoin
Siraj Raval has tried just about every way there is to mine for cryptocurrencies from his Tesla Model 3. He's run free bitcoin mining software on his Apple Mac mini M1 and powered the computer by plugging an inverter into the volt power socket located in the center console of his car. He's also hooked up interconnected graphics processing units or GPUs to the "frunk" of his Tesla, running these machines off the car's internal battery. Bitcoin miner Alejandro de la Torre said that ultimately, mining from a Tesla is just like connecting to any other power source.

By Matthew Sparkes. Bitcoin is a digital currency which operates free of any central control or the oversight of banks or governments. Instead it relies on peer-to-peer software and cryptography. A public ledger records all bitcoin transactions and copies are held on servers around the world. Anyone with a spare computer can set up one of these servers, known as a node.
Kazakhstan internet shutdown deals blow to global bitcoin mining operation
Over a decade ago, it used to be incredibly easy to mine bitcoin from home. Despite one in a million exceptions like the bitcoin miner who managed to mine a block solo in January , such crazy times are now a distant memory. The Bitcoin network has become so huge that mining operations with entire warehouses full of powerful, custom-purpose mining machines now compete against each other to earn block rewards. But there are ways in which cryptocurrency mining can still be profitable for the average person — and not just from bitcoin. In exchange for their effort, each successful miner is rewarded with newly minuted cryptocurrency and any fees attached to the transactions they include in the new block. Read more: How Bitcoin Mining Works. As more powerful machines reach the market, your once-powerful machine might not be able to keep up.
Why China Is Cracking Down on Bitcoin Mining and What It Could Mean for Other Countries
In cryptocurrencies, a private key allows a user to gain access to their wallet. The person who holds the private key fully controls the coins in that wallet. For this reason, you should keep it secret. And if you really want to generate the key yourself, it makes sense to generate it in a secure way.
