Deep Tide TechFlow News, January 23 — According to the latest report from CoinDesk, the active addresses on the Ethereum blockchain briefly surpassed 1.3 million in January 2026, surpassing major Layer-2 networks such as Arbitrum and Base. This growth was mainly driven by the Fusaka upgrade in December last year, which significantly reduced transaction fees. However, security researcher Andrey Sergeenkov analyzed that about two-thirds of this data is related to "address poisoning" attacks, where attackers send small amounts of stablecoins to millions of wallets to trick users into copying similar addresses for transactions. This attack has resulted in confirmed losses of at least $740,000.
