Ether Labs proposes security transition in 2027… US Senate requests materials from Tether and others

Ethlabs proposed accelerating Ethereum’s quantum- and AI-resilience work under its pqai27 plan, targeting by 2027 a consensus framework and user-account migration path that can withstand quantum attacks, though the timeline is not yet a developer-approved upgrade schedule. The proposal also withdraws Ethlabs’ support for “quick slots” — shorter block times — in the Hegota upgrade and redirects those resources toward security development. Separately, Tether’s USDT market capitalization fell $6.6 billion over the past 60 days, a notable contraction for the largest stablecoin. The Ethereum plan matters because it would put post-quantum defenses on a concrete, if provisional, calendar while changing near-term upgrade priorities. What to watch next is whether Ethereum developers formally adopt the 2027 targets and how USDT’s supply trend develops after the recent decline.
