Arbitrum DeFi Ostium, 26.8 Billion Won Leaked Due to Oracle Time Manipulation

Approximately 26.8 billion won (about $18 million USD) in funds have been drained from an Arbitrum (ARB) based DeFi project due to a sophisticated attack involving oracle price data manipulation. The attacker exploited the 'PriceUpKeep forwarder' component of Ostium's automated infrastructure by submitting price data with future timestamps to create seemingly advantageous transactions, ultimately stealing USDC.

New Ethereum proposal would cut issuance to zero if staked ETH reaches $112 billion - CoinDesk

Rewritten: Ethereum proposal: zero new ETH if $112B staked.

A new Ethereum proposal suggests cutting new ETH issuance to zero if the total value of staked ETH reaches $112 billion, potentially making the cryptocurrency deflationary.

A significant shift in Ethereum's economic model, potentially leading to zero net issuance, could fundamentally alter the digital asset landscape. Such a development would position ETH as a deflationary asset, a characteristic that has historically attracted significant investor interest and could bolster its appeal as a store of value. This potential scarcity could resonate with broader market trends favoring assets with limited supply, especially in an environment where traditional currencies face inflationary pressures. Increased confidence in Ethereum's long-term value proposition, driven by this supply-side innovation, might encourage greater risk appetite among investors seeking exposure to digital assets with a perceived strong fundamental underpinning. The reduction in issuance could also amplify the narrative of Ethereum as a maturing and increasingly robust financial primitive within the decentralized ecosystem.
