first_img Etherealize CEO warns Wall Street about the revival of alliance chains: Fragmenting the ecosystem will undermine blockchain interoperability

Vitalik Buterin and Etherealize co-founder and CEO Vivek Raman, supported by the Ethereum Foundation, warned that Wall Street's renewed enthusiasm for private, permissioned "consortium chains" is recreating a fragmented system, undermining the interoperability and liquidity that blockchain should bring, akin to "race to the bottom." He pointed out the rise of gated networks such as Digital Asset's Canton Network, Circle's ARC, and Stripe's Tempo, reminiscent of the R3 and Hyperledger consortium chains 2.0 from years past, where institutions will ultimately find themselves in a situation of competing consortium chains, needing permission or membership to participate.Raman emphasized that the Ethereum mainnet should serve as a globally open, permissionless foundation layer similar to HTTP, where institutions can overlay permission and privacy features at the application layer or L2 to achieve maximum interoperability and liquidity. Etherealize is committed to attracting TradFi to embrace Ethereum, which has already hosted billions of dollars in tokenized assets and supported a large amount of DeFi settlements. The company received seed funding from Buterin and the foundation in January 2025 and completed a $40 million Series A financing in the same year.He cited examples such as BlackRock's new fund based on Ethereum, stating that once regulations are clear, institutional funds are more inclined towards open network tracks that are not proprietary; choosing consortium chains would require paying the consortium and being bound by its rules, with incentives for non-early members quickly fading. Christian Catalini, founder of the MIT Cryptoeconomics Lab, also pointed out that if permissioned networks driven by enterprise sales become mainstream, some competitive benefits of blockchain may not be realized.

Berkshire's first major portfolio adjustment revealed, spending $17 billion in the second quarter to bet on Google

Berkshire Hathaway submitted its 13F holdings report for the second quarter of 2026 to the U.S. SEC. The data shows that in the second quarter after Warren Buffett stepped down, the company's investment portfolio underwent significant adjustments, with a large purchase of Google’s parent company Alphabet, while reducing positions in the financial and consumer sectors.As of June 30, 2026, the total market value of Berkshire's stock holdings rose to $29.9 billion, up from $26.3 billion in the previous quarter. In the second quarter, the company added one new position, increased holdings in seven stocks, reduced holdings in six stocks, and completely sold out of one target, with the top ten holdings accounting for as much as 88.74%.Among them, Alphabet became the biggest highlight. In the second quarter, Berkshire cumulatively increased its holdings of Alphabet Class A and Class C shares by approximately 48.1 million shares, with the new holdings valued at over $17 billion, pushing Google to replace Bank of America as Berkshire's fourth-largest holding. Currently, its top five holdings are Apple, American Express, Coca-Cola, Alphabet, and Bank of America. In addition to Google, Berkshire also slightly increased its holdings in Delta Air Lines, Lennar, and Macy's. The increase in Delta Air Lines has attracted attention, as the market believes this move may reflect the company's optimism about the recovery of air travel demand and improvement in corporate operations.On the reduction side, Berkshire focused on cutting positions in the financial and consumer sectors in the second quarter. Among them, Bank of America saw a reduction of about 30.2 million shares, with the holding ratio decreasing by 5.89%, corresponding to a market value of about $1.72 billion, making it the largest reduction target; First Capital Financial reduced about 4.2 million shares, with the holding ratio decreasing by about 58%; at the same time, it reduced about 11 million shares of Kroger, with the holding size decreasing by about 22%.The market believes that Berkshire ended a streak of 14 consecutive quarters of net stock selling in the second quarter and net bought nearly $20 billion in stocks, indicating that the new leader Greg Abel is pushing the portfolio towards a technology growth direction, marking a shift in asset allocation in the "post-Buffett era."
