Sep 9 — Bank stablecoin, Cronos rollback, and ETH quantum plan

• A consortium of 21 major banks including BofA, Citi, and Goldman committed to a joint USD stablecoin — a landmark move that validates the asset class and poses a direct threat to USDT and USDC. • Cronos rolled back its blockchain to recover $111 million lost in an exploit — raising serious questions about the network's decentralization and immutability guarantees. • Ethereum's Foundation set a 2029 deadline to make the base layer quantum-resistant across execution, consensus, and data — a technical milestone other L1s will likely need to match.
