Ethereum, the second most popular cryptocurrency after Bitcoin, has completed a software upgrade that aims to make its network cheaper. Called Dencun, the update lowers the cost of so-called layer-2 networks — which include chains like Base, Polygon and Arbitrum — to about a cent for transactions that previously cost $1, while exchanges that used to cost a few cents are reduced to fractions of a cent. Accomplished through a new system of storing data, the upgrade is being welcomed as a harbinger of a development renaissance brimming with new applications and free services.

After a tumultuous two-year slump, Bitcoin rebounded this week when it briefly reached a new all-time high exceeding $69,000, marking a more than 300 percent rise since November 2022 when the price was below $20,000. The prior record of just below $68,790 dates back to November 2021. The 2024 rally comes on the heels of regulatory action approving rules that make it simpler for individuals to invest in Bitcoin by allowing some large investment firms including BlackRock, Fidelity, Grayscale and Valkyrie to add it to their funds, making it easier for the average investor to choose it as a portfolio option.

Mining on the blockchain is a notorious energy hog and bad for the environment. Ethereum is on the verge of a big change aimed at substantially reducing its carbon footprint. After seven years of using the traditional proof-of-work mining technique, Ethereum is switching to the more efficient proof-of-stake method that is expected to reduce energy consumption by 99.5 percent. That change, known as The Merge, is scheduled to take place September 14. The Merge will see Ethereum’s proof-of-work blockchain fused with the proof-of-stake Beacon Chain, which launched in December 2020 but has yet to process its first transaction. Continue reading Ethereum’s Proof-of-Stake Method Will Reduce Energy Use

Cryptocurrency bridges, which enable transactions across a wide range of token types, are an increasingly important factor in the world of blockchain. A hack involving approximately $540 million in Ethereum and USDC stablecoin from the Ronin bridge in March was another drop in the $1 billion-plus bucket stolen from bridges. Successful attacks have become more common in recent years and the Ronin heist, among the largest, underscores a bigger problem. Different cryptocurrencies are typically siloed, so a Dogecoin transaction can’t be implemented on the Bitcoin blockchain, but it can by using a bridge.

There are reports of a migratory wave of executives and engineers moving from Big Tech firms such as Google, Amazon, Apple and others to chase what is being described as “a once-in-a-generation opportunity” with startups whose business models rely on blockchain and involve everything from cryptocurrencies to non-fungible tokens. Google is said to be so worried about employee retention they’ve increased stock grants in categories vulnerable to poaching following the exit of Surojit Chatterjee to join Coinbase where he saw his stake in the company grow to more than $600 million in 14 months. Continue reading Big Tech Concerned About Crypto Startups Poaching Talent

Startup Coinbase, a secure exchange platform that helps people purchase, sell and store cryptocurrencies, has become the first such startup to go public. Shares traded at $381 each, up 52 percent from a reference price of $250, and eventually closed at $328.28, for a company valuation of $85.7 billion, ten times higher than its last private valuation. The San Francisco-based company’s IPO is a landmark for long-time crypto advocates. In its wake, Bitcoin’s value soared to $64,829 and Ether traded at a record-high of $2,487 (which also followed news about upgrades to the Ethereum network). Continue reading Coinbase Becomes First Cryptocurrency Startup to Go Public

The Bitcoin market, almost a decade old, is now skyrocketing in value. Behind Bitcoin’s rising price are investments by Japanese investors and a heightened perception of global perils. Over the weekend, according to the website CoinDesk, the price of Bitcoin reacted to a sudden spell of speculative investment, trading above $2,200 on Monday, which represents more than 15 percent from the closing price of $1,913 on Friday. Bitcoin is up 397 percent from a year ago and 130 percent this year. Continue reading Bitcoin Market Trending Upwards, But Ethereum On the Rise

Hong Kong exchange Bitfinex was hacked and funds were stolen, marking a setback for digital currency Bitcoin. Bitfinex director of community and product development Zane Tackett posted on Reddit that 119,756 Bitcoins had been stolen. “Before the hacking was made public, that number of Bitcoins would have been worth about $72 million,” explains The New York Times. “Now that the currency has slumped, the figure is closer to $65 million.” During its investigation, Bitfinex has stopped all trading, deposits and withdrawals. The security breach is the latest in a series of events that could impact the viability of virtual currency. Continue reading Latest Cryptocurrency Cybertheft Could Shake Faith in Bitcoin

J.P. Morgan Chase, Wells Fargo and other banks just introduced real-time person-to-person payments — something PayPal’s Venmo has done for years — to their five year-old joint effort clearXchange. Previously, clearXchange could take up to three days to transfer money. PayPal upped its game, by signing a deal with Visa to let Venmo and PayPal app users instantly access monies they receive. PayPal and the banks collect no fees on these transactions, which they regard as a gateway to other, paid services. Continue reading Banks Make Move to Real-Time Person-to-Person Payments

The Decentralized Autonomous Organization raised $160 million in Ether, a virtual currency that is an alternative to Bitcoin. The experimental project was hailed as the most successful crowdfunding effort ever, until last Friday when a hacker made away with more than $50 million. Although the hack was frozen and the project’s computer scientists plan to rewrite Ether’s code to recover the money, the project most likely will end, leaving in its wake a bigger debate than ever about the viability of virtual currency.
