Ethereum Merge set to make cryptocurrency greener – CTV News

Published

 on


A huge shift is about to be underway for the second-most widely circulated cryptocurrency that could drastically reduce the amount of energy it uses.

In a move that’s been dubbed “The Merge,” Ethereum is set to change the way it validates its transactions, from a “proof-of-work” system to a “proof-of-stake” system, which the Ethereum team says will reduce energy consumption by 99.95 per cent.

Currently, the amount of energy that Ethereum uses is about 112 terawatt hours annually. To put that into perspective, that’s more electricity than what the entire country of Pakistan uses in a year.

Here’s how the cryptocurrency plans to go green:

DITCHING PROOF-OF-WORK

Cryptocurrencies like Ethereum are all decentralized, which means that the ledger, or the records of transactions, is stored on multiple computers in a network.

Currently, Ethereum relies on a proof-of-work system to validate the transactions and update the ledger. This means that each transaction requires advanced computers to solve an extremely complex mathematical equation in order to add it to the ledger, in a process called “mining.”

When a new transaction comes in, all of the computers on the network solve try to solve the math equation, and whichever computer solves it first is rewarded with some currency as a payment.

But this has incentivized Ethereum “miners” to invest in large numbers of more powerful and energy-intensive computer hardware in order to give them a better chance of making money through mining.

Miners are also pooling their hardware together in what are known as “mining pools.” Much like an office lottery pool can give you a higher chance of winning the grand prize, mining pools operate on the same principle, splitting their profits among their members.

But just three mining pools make up more than half of the computing power on the Ethereum network, leading to concerns that the cryptocurrency is becoming too centralized. If a single mining pool were to gain control of more than 50 per cent of the computing power on the network, they could effectively take over the currency and have the ability to approve fake transactions. This is what’s known as the “51 per cent attack.”

HELLO PROOF-OF-STAKE

Cryptocurrencies like Ethereum have been the target of criticism from environmentalists, who point to the high levels of energy consumption. But after the Merge, Ethereum will transition towards a proof-of-stake system, which is expected to use only 0.05 per cent of the energy the cryptocurrency currently uses.

The current system relies on having millions of high-powered computers trying to solve the same math equations at the same time, and proponents of proof-of-stake say this is an enormous waste of energy.

Under a proof-of-stake system, only one computer is selected to validate the transaction. In order to participate as a validator, a user needs to deposit or “stake” 32 ETH. If the transaction is successfully validated, the validator will receive the transaction fees as a reward.

While it may seem riskier to rely on just one validator, the system does have safeguards. The validations are verified by other computers on the network, and if a validator approves a fraudulent transaction, the validator loses a part of their stake.

Theoretically, a 51 per cent attack can still occur if one entity buys up more than half of all the Ethereum supply, but this is highly impractical as doing so would cost nearly US$100 billion.

The Merge is set to take effect at around 1 a.m. EDT early Thursday morning. It’s unclear what long-term effect the Merge could have on the price of Ethereum. As of Wednesday evening, the cryptocurrency was up around 4.00 per cent since the start of the day.

Retail sales fall for 1st time this year as consumers start to tap out – CBC News

Published

 on


Facing sky-high inflation, consumers put away their wallets more often in July, new data revealed Friday, as retail sales fell for the first time since 2021.

Canadian retailers rang up $61.3 billion in sales in July, Statistics Canada reported Friday. That’s a decline of 2.5 per cent from the previous month’s level as lower sales at gas stations and clothing stores led the way down.

Sales at gas stations fell by 14 per cent. A big part of that was lower prices for the fuel itself, but even in volume terms sales were down by seven per cent. Fewer people were filling up during the month, which was in keeping with the vehicle segment overall as auto sales edged down 0.5 per cent. Both new and used car dealers reported declines.

Consumables like food and drink also weren’t flying off the shelves, as supermarkets and grocery stores saw sales slip by 0.9 per cent, while liquor stores saw a decline of 1.2 per cent.

The soft retail sales numbers suggest consumers are starting to put away their wallets in the face of sky-high prices and a gloomy outlook for the economy.

“This retail sales report was unambiguously weak, suggesting that consumers tightened their purse strings in July,” TD Bank economist Ksenia Bushmeneva said of the numbers. “Consumer demand appears to have broadly cooled across most categories of spending.”

“All in all, given the triple headwinds emanating from higher consumer prices, rapidly rising interest rates and a drop in wealth, consumers are becoming more frugal,” she said.

Dow drops but narrowly avoids confirming bear market status – Reuters.com

Published

 on


Sept 23 (Reuters) – The blue-chip Dow Jones Industrial Average (.DJI)tumbled to its lowest level since November 2020 on Friday, but narrowly missed ending more than 20% below its Jan. 4 closing record high.

A Dow close below 29,439.72 would have confirmed a bear market that began from that record, according to a widely used definition. read more The Dow fell 486.27 points, or 1.62%, to end at 29,590.41.

The Dow is the only one of the three main indexes not to have bear market status. The S&P 500 (.SPX) notched that grim milestone in June and the Nasdaq (.IXIC) in March.

The renewed selling pressure in markets came in a week that saw the U.S. Federal Reserve raise interest rates by three-quarters of a percentage point for a third straight time and a vow to keep it going until inflation is under control.

It has been a tumultuous year for Wall Street, plagued by worries about Russia’s invasion of Ukraine, an energy crisis in Europe and the end of easy money policy globally.

The S&P 500 has lost 23% this year and the Nasdaq has shed 31%.

The last time the three indexes pulled back so sharply was in 2020 during the heights of the pandemic selloff.

Heightened fears of a U.S. economic downturn next year and its impact on corporate profits has prompted brokerages to downgrade their year-end targets for the S&P 500. read more

TSX slumps as oil falls below $80 and economic gloom settles in – CBC News

Published

 on


Canada’s benchmark stock index dropped heavily on Friday as prospects of a global recession cause investors to sell first and ask questions later.

The S&P/TSX Composite Index was off by more than 520 points or 2.75 per cent to close at 18,480, dragged down by a plunge in the price of oil. That’s the lowest level for the benchmark Canadian stock index since July.

The benchmark price of crude oil in North America lost almost $5 to close at $79.13 a barrel, its lowest price since January. The catalyst for oil’s decline seems to have been central banks signaling this week that they are so committed to reining in inflation that they are willing to create a recession to achieve it.

The U.S. Federal Reserve hiked its benchmark interest rate on Wednesday, and nine other countries around the world followed suit the next day. That will help bring down inflation, but it will likely come at great cost to the economy.

“Clearly what they are saying is they are so determined to bring inflation down that they are going to bring down the economy in the process,” said John Zecher, the founder of Toronto-based money manager J Zechner & Associates. “That’s the way the market is reading it … They aren’t going to stop until the economy turns down.”

Oil price down to lowest since January

A recession would lead to much less demand for energy, which is why oil sold off. About a fifth of the companies on the TSX are in the energy sector, and they were among the biggest losers Friday. Shares in Suncor, Cenovus, MEG Energy and Crescent Point all lost more than eight per cent on the day.

More and more economic indicators are starting to suggest Canada’s economy either already has derailed or is about to. Employment numbers last week showed the economy has lost jobs for three months in a row, and retail sales data on Friday showed that Canadians are putting away their wallets once more.

Stock markets are responding to that gloom, and some analysts think there is a lot more pain to come.

“The lows that we saw recently in the summer months are going to be challenged in the next couple of days to weeks,” said Larry Berman, chief investment officer with Toronto-based money manager QWealth, in an interview.  “The market [isn’t] priced for what the central banks are going to do.”

The Canadian dollar dipped as low as 73.61 cents US, its lowest level in more than two years.

Shares in New York also sold off, with the Dow Jones Industrial Average closing down almost 500 points to 29,590 — its lowest level of the year.

“Over the next couple of weeks, long-term investors may hesitate buying into weakness,” said Edward Moya, an analyst with foreign exchange firm Oanda. “How far we go below the summer lows is anyone’s guess.”
