Ripple Co-founder Argues Need for Bitcoin to Switch from Proof-of-Work (PoW)



On Earth day, Chris Larsen in a blog post argued why he thinks Bitcoin needs to reconsider Proof-of-Work when validating transactions. As the oldest and the world’s most dominant crypto asset, its core technology remains largely unchanged.

The world is changing and there is an increasing need for renewable energy and more energy-efficient uses. Though financially revolutionary, Bitcoin has long been one of the highest power consumers. A recent study revealed that Bitcoin consumes more power than some countries, in light of this, Ripple co-founder Chris Larsen has pointed out that the Proof-of-Work (PoW) is no longer pertinent. The billionaire points out that this was also a concern for Hal Finney, one of the earliest Bitcoin adopters and only one of a few people who had contact with Satoshi Nakamoto the creator of Bitcoin.

In a blog post, Larsen pointed out several key issues with PoW. Primarily, CO2 emissions and consumption of energy. In recent years, miners have been switching to renewable sources of energy. Some have also argued that Bitcoin uses ‘trapped energy,’ energy that would have otherwise gone to waste. But as the co-founder notes, this is only part of the solution.

Should Bitcoin Re-consider PoW?

He draws a comparison to Ethereum which is currently in the process of switching from PoW to a new validation process referred to as Proof-of-Stake (PoS). Other major players that have already implemented this include Binance coin (BNB) with a market cap of over $80 billion. This is proven to be more energy-efficient and successfully adopted by 43% of the cryptocurrencies in the market.

But Larsen points out this is not the only solution and Bitcoin has. Another option could be Federated Consensus which is used on the XRP Ledger. In fact, the solution could be ‘something yet to be developed’.

“I would argue that such a change is critically important for Bitcoin to remain the world’s dominant cryptocurrency. PoW’s current energy demands and carbon footprint are already unsustainably high, with Bitcoin alone consuming an average of 132 TWh a year (equivalent to roughly 12 million U.S. homes), and releasing an estimated 63 million tons of CO2 annually”, added he.

Institutions Role

As Bitcoin continues to surge, energy consumption and CO2 will continue to rise, this should at least raise a concern to companies like Tesla who want to invest in the financial evolution and reduce the impact on climate change. “Consider Tesla’s recent investment in bitcoin, which resulted in an over $5,000 per bitcoin price increase. Incredibly, this almost certainly wiped out Tesla’s entire fleet’s annual CO2 savings,” wrote Larsen.

The co-founder’s comments are timely for institutions, miners, developers and even retail developers to get the community talking as the world celebrates world earth day.

Ethereum price closes in on $4K as Shiba Inu (SHIB) steals Dogecoin’s thunder




The crypto market has rallied into the weekend as Ether (ETH), Dogecoin (DOGE) and Shibu Inu (SHIB) hit new all-time highs as they lead the pack of altcoins up the market cap mountain. 

Much of the excitement behind Dogecoin’s rally has been attributed to the upcoming appearance of Elon Musk, the CEO of Tesla and a Dogecoin advocate, on the popular Saturday Night Live comedy sketch show. Ether, on the other hand, continues to rally toward $4,000 as institutional interest in the altcoin soars and the approaching London hard fork have investors feeling extra bullish.

Data from Cointelegraph Markets and TradingView shows that after briefly dipping to a low of $3,418 in the late hours on May 8, Ether price regained its composure and proceeded to vault 13% to reach a new all-time high at $3,958.

While some have been surprised by the bullish movement from the second-largest cryptocurrency by market capitalization, it comes as no shock to Cointelegraph market analyst Marcel Pechman who recently detailed how Ether “could easily sustain until $5,000.”

Bitcoin (BTC) has used its time out of the spotlight to quietly climb higher with bulls now attempting to hold the price above $59,000.

Canine-themed ‘meme coins’ lead the pack

Dogecoin has emerged as one of the biggest mainstream attention grabbers in cryptocurrency history as scores of new users got their first taste of crypto trading from the popular meme token.

The week-long build-up in momentum for DOGE led to a 25% surge in the early trading hours on Saturday that lifted its value to a new all-time high at $0.74 before profit-taking dropped the price back below $0.68.

Thanks to the global attention that Dogecoin has attracted, a number of canine-themed projects have arisen, including Shiba In (SHIB), which burst onto the scene following a two-day rally that saw its value launch 1,100% higher to establish a new record high at $0.0000178.

The overall cryptocurrency market cap now stands at $2.463 trillion and Bitcoin’s dominance rate is 44.8%.
