  • The Impossibility of Perfect Fairness in Transaction Ordering
    Cointelegraph.com - 15:00 Jun 24, 2026
    Why perfect fairness cannot hold in asynchronous networks, and how different blockchains adopt different relaxations to fairness. Consensus guarantees today, focus on two properties: Consistency and Liveness. Consistency requires that all nodes eventually agree on the same set and sequence of transactions, while liveness ensures the system continues to process new transactions. What they do not address is whether the agreed-upon transaction order totally reflects fairness. In public blockchains, transaction ordering has direct economic consequences. The order in which transactions execute determines who captures value and who pays the cost, particularly as validators, block builders, or sequencers can exploit their privileged role in block construction for financial gain. This practice is known as maximal extractable value (MEV) and includes the profitable frontrunning, backrunning, and sandwiching of transactions. Prima facie, there is no obvious way to prevent MEV extracting practices because block proposer...
  • How memecoin marketing moved from online speculation to real-world risk
    Cointelegraph.com - 14:30 Jun 24, 2026
    From alcohol dares to head-shaving challenges, memecoin campaigns are turning engagement into exploitation. When virality moved off-screen Memecoins have never pretended to be serious. Other blockchain projects often present themselves through promises of faster payments, scalable infrastructure or decentralized applications (DApps). Memecoins, however, draw their appeal from humor, absurdity and internet culture. A photo of a dog can become a billion-dollar asset. A frog image can trigger a wave of speculation. Communities come together around shared jokes, catchphrases and collective excitement, often with little logic beyond the energy of participation. Read more
  • DeFi TVL drops 39% in 2026 amid market downturn and record hack activity
    Cointelegraph.com - 14:14 Jun 24, 2026
    DeFi TVL fell 39% in 2026 as a broader market downturn and fallout from major exploits, including the Kelp DAO hack, weighed on the sector. Total value locked (TVL) in decentralized finance (DeFi) has fallen by about 39% in 2026 so far, declining to just over $70 billion from roughly $115 billion in January.

After Bitcoin reached a record high above $122,000, a market-wide liquidation event on Oct. 10, 2025, erased more than $19 billion in leveraged positions and accelerated a deleveraging cycle across digital assets.

    Cointelegraph.com - 06:06 Jun 24, 2026
    The House passed a housing bill with a central bank digital currency ban until 2030, meaning it now just needs US President Donald Trump’s sign-off. The US House has passed a major housing bill that includes a ban on central bank digital currencies until 2030, in what is set to be a major win for Republicans who have long pushed for such a measure.

The bill now heads to US President Donald Trump, who has signaled support for the measure and is expected to sign it into law on Wednesday. “Today, Congress delivered a major win for families working toward the American Dream,” said Senate Banking Committee Chairman Tim Scott. “I look forward to President Trump signing it into law.” Read more
  • Catholic leaders, US authorities challenge CLARITY Act over illicit activity
    Cointelegraph.com - 06:06 Jun 24, 2026
    “Regulatory certainty should not come at the expense of accountability, transparency, victim protection, or public safety,” the law enforcement associations said. A group of law enforcement organizations and a coalition of Catholic organizations have become the latest two groups urging caution over the US CLARITY Act, which is heading for a key hearing in July. In letters sent Tuesday, four law enforcement organizations reached out to White House officials with concerns that the CLARITY Act could create oversight gaps when it comes to illicit activity. “Regulatory certainty should not come at the expense of accountability, transparency, victim protection, or public safety,” they said. The Alliance to End Human Trafficking, founded by US Catholic Sisters, said these oversights could make it harder to crack down on human trafficking. Read more

    The Swedish health-tech company moved closer to becoming one of Europe's largest publicly traded Bitcoin treasury firms after shareholders approved a key condition for its planned acquisition of two Norwegian investment companies.

The Wall Street Journal reported in January that an Abu Dhabi investment company backed by Sheikh Tahnoon bin Zayed Al Nahyan, the United Arab Emirates’ national security adviser, signed a deal in January 2025 to buy a 49% stake in World Liberty Financial, the crypto platform tied to US President Donald Trump.

  • Ethereum’s much-hated staking 'tax' may already be obsolete
    Cointelegraph.com - 23:18 Jun 23, 2026
    Ethereum’s latest “funding crisis” has triggered a fierce debate over whether to tax staking rewards or to pursue funding from large ETH holders for new organizations like EthLabs. Ethereum is running out of money, according to former insiders. The warning has sparked one of the fiercest Ethereum governance debates in months: should the network fund developers by taxing staking rewards, or just rely on wealthy Ether holders to bankroll its ecosystem? At the center of the debate is a controversial proposal from Kleros co-founder Clément Lesaege. He suggested redirecting up to 10% of validator rewards to ecosystem funding through a protocol-level mechanism called Validator Redirected Revenue. Read more
