Ethereum's Glamsterdam Drops in Q3 2026: Slower Block Time, Bigger Dreams 🏗️

Ethereum [ETH] is preparing to roll out the Glamsterdam upgrade in Q3 of 2026, with the focus on improving how the network processes transactions rather than introducing new features. Ethereum Improvement Proposal (EIP)-7732 extends the block-building and propagation window from about two seconds to nine seconds, allowing the network to handle larger amounts of data more efficiently. EIP-7928 enables the network to identify transaction requirements before processing them, supporting parallel execution of multiple transactions. Updated fee rules aim to support higher network capacity without overloading the system.

The scalability story is increasingly being shaped by Layer-2 networks rather than the main chain itself. According to DeFiLlama data, Base holds more than $4.2 billion in DeFi value, while Arbitrum [ARB] secures roughly $1.3 billion. Activity has continued to migrate toward rollups as users sought lower costs and faster execution than the main network could consistently provide, reinforcing their role as the ecosystem's primary execution layer. While rollups reduce congestion and expand capacity, they also deepen reliance on Ethereum for settlement and security.

BitMine's Ethereum accumulation continued as transaction data revealed another 20,000 ETH purchase worth roughly $35.85 million through FalconX. The acquisition extends a broader strategy that has lifted the firm's holdings to about 5.6 million ETH, representing nearly 4.7% of circulating supply. The timing comes as Ethereum has faced recent market pressure and uneven ETF demand, with BitMine adding exposure rather than reducing it. Much of its treasury remains staked, reinforcing a yield-focused approach. The accumulation concentrates more supply among institutional holders, increasing their market influence as activity grows across both layers.
