Ethereum Foundation Says Berlin Hard Fork Addressed 'Clear and Present' Threat
The vulnerability was first discovered in late 2019.

The Ethereum Foundation, the organization that supports the blockchain with the same name, said the recent Berlin hard fork that tinkered with "gas" prices and allowed new transaction types on the blockchain also fixed a longstanding "clear and present danger" to the platform.
- The flaw, which left the protocol vulnerable to attack, was an "open secret" in the Ethereum community and had been known about since October 2019, the foundation said in its blog post disclosing both the problem, and that it has now been fixed.
- The foundation said it's disclosing the now-fixed vulnerability in the interest of transparency.
- "We estimate that the threat is low enough that transparency trumps, and it's time to make a full disclosure about the works behind the scenes," the foundation wrote.

KuCoin Hits Record Market Share as 2025 Volumes Outpace Crypto Market

KuCoin captured a record share of centralised exchange volume in 2025, with more than $1.25tn traded as its volumes grew faster than the wider crypto market.
What to know:
- KuCoin recorded over $1.25 trillion in total trading volume in 2025, equivalent to an average of roughly $114 billion per month, marking its strongest year on record.
- This performance translated into an all-time high share of centralised exchange volume, as KuCoin’s activity expanded faster than aggregate CEX volumes, which slowed during periods of lower market volatility.
- Spot and derivatives volumes were evenly split, each exceeding $500 billion for the year, signalling broad-based usage rather than reliance on a single product line.
- Altcoins accounted for the majority of trading activity, reinforcing KuCoin’s role as a primary liquidity venue beyond BTC and ETH at a time when majors saw more muted turnover.
- Even as overall crypto volumes softened mid-year, KuCoin maintained elevated baseline activity, indicating structurally higher user engagement rather than short-lived volume spikes.

Gold tops $5,000 as bitcoin stalls near $87,000 in widening macro-crypto split: Asia Morning Briefing

Bitcoin’s onchain data points to supply overhang and weak participation, while gold’s breakout is priced by markets as a durable macro regime shift.
What to know:
- Gold’s surge above $5,000 an ounce is increasingly seen as a durable regime shift, with investors treating the metal as a persistent hedge against geopolitical risk, central bank demand and a weaker dollar.
- Bitcoin is stuck near $87,000 in a low-conviction market, as on-chain data show older holders selling into rallies, newer buyers absorbing losses and a heavy supply overhang capping moves toward $100,000.
- Derivatives and prediction markets point to continued consolidation in bitcoin and sustained strength in gold, with thin futures volumes, subdued leverage and weak demand for higher-beta crypto assets like ether reinforcing the cautious tone.
