Ethereum News Today: ETH Whale Stakes $3.84M After Kraken Withdrawal
Ethereum remains at the center of crypto headlines today, with a mix of protocol-level changes and market activity shaping the narrative. A new proposal aims to trim how long historical block data is retained by consensus layer clients, easing storage burdens on node operators.
Meanwhile, institutional and whale activity continues at pace — from Russia's largest exchange planning new derivatives products to major holders staking and accumulating ETHs.
This roundup covers the technical proposal, exchange developments, and on-chain movements worth tracking for anyone following Ethereum news today.
Ethereum News Today: EIP-12188 Proposes Shorter Historical Block Retention
Ethereum developer kevaundray has introduced EIP-12188, a proposal designed to shorten the amount of time consensus layer (CL) clients are required to retain historical block data. The goal is straightforward: reduce the storage footprint that node operators must maintain, making it easier and cheaper to run a node over time.
The proposal has now moved into public review, where client teams and community members can weigh in before any further steps toward implementation. This kind of storage optimization has long been discussed within Ethereum's developer community as the chain's history continues to grow year after year.
Ethereum Historical Data Pruning: What EIP-12188 Means for Nodes and Old Blocks
A key distinction in this proposal is the difference between the consensus layer (CL) and the execution layer (EL). EIP-12188 specifically targets CL block retention, though discussions note that if the execution layer eventually introduces its own historical data pruning, the combined effect would primarily limit the ability to query very old blocks rather than compromise the chain itself.
Developers involved in the conversation have been clear that this change is not expected to weaken network security or disrupt how nodes function day to day — the impact is mostly confined to historical data lookups rather than core protocol operations.
Lighthouse, one of Ethereum's major consensus layer clients, has expressed support for the proposal, an early signal that client-level backing could help the EIP progress smoothly through further review stages.
Moscow Exchange Plans BTC and ETH Perpetual Futures for Professional Investors
Outside of core protocol development, Moscow Exchange has announced plans to launch perpetual futures contracts for Bitcoin and Ethereum, targeting professional investors. Unlike the monthly and quarterly futures already available on the platform for BTC, ETH, SOL, XRP, and TRX, perpetual futures carry no fixed expiration date and roll over automatically, giving traders more flexible position management.
The exchange has signaled ambitions to expand its crypto derivatives lineup further, eventually covering up to ten digital assets. Reports also point to Moscow Exchange preparing a separate digital settlement and custody system to support broader digital asset offerings going forward.

BitMine Adds 9,926 ETH as Holdings Reach 5.82 Million ETH
On the institutional accumulation side, BitMine added 9,926 coins to its balance sheet over the past week, pushing total holdings to 5,815,164 coins— roughly 4.8% of Ethereum's entire circulating supply.
The firm has staked about 5.07 million coins, or nearly 87% of its total holdings, with projected annualized staking revenue estimated near $250 million. BitMine also bought back 1.7 million shares during the week, bringing cumulative repurchases since July past 20.8 million shares, while total crypto, cash, and other investments reached $11.4 billion.
Ethereum Whale Stakes $3.84M After Withdrawing 10,657 ETH From Kraken
A closely watched wallet continued its accumulation streak, staking 2,020 coins (about $3.84 million) through the Ethereum Beacon Deposit Contract. The same address withdrew another 5,000 tokens (around $9.53 million) from Kraken exchange, bringing its total withdrawals and purchases to 10,657 tokens, worth roughly $20 million. The pattern suggests a deliberate strategy of pulling Ethereum coins off exchanges and locking them into staking.
Pando Rings Exploiter Moves $3 Million in ETH After Two Months
An address linked to the 2022 Pando Rings exploit, which drained about $20 million through an oracle manipulation attack, became active again after two months of dormancy. The wallet swapped 3 million DAI for roughly 1,570 tokens (around $3 million) via CoW Protocol, then routed 800 tokens (about $1.52 million) to Tornado Cash across eight separate transactions.

Ethereum Whale Loses 217 ETH by Selling Low and Buying High
Not every large holder is timing the market well. One wallet repurchased 1,674 ETH for about $3.19 million at a high price point near $1,906 per token. Two months earlier, the same wallet held 1,891 ETH, meaning its swing-trading approach has cost it 217 ETH (roughly $414,000) in value — a reminder that active trading doesn't always outperform simply holding.

Ethereum News Today: Key ETH Developments to Watch Next
Looking ahead, EIP-12188's public review process, potential execution layer pruning changes, ongoing staking inflows, institutional accumulation from firms like BitMine, and continued whale activity are all worth monitoring. Moscow Exchange's derivatives expansion also adds another institutional access point for exposure.

Together, these developments highlight a network evolving on both infrastructure and adoption fronts, even as isolated incidents like the Pando Rings exploiter's movements serve as reminders of past vulnerabilities still playing out on-chain.
