Ethereum makes quantum resistance a top priority with a 2029 deadline
60-second summary
Ethereum prioritizes quantum resistance, targeting a 2029 deadline to safeguard the network before plausible quantum computers can break current cryptography. The Ethereum Foundation states upcoming upgrades will be evaluated against this timeline, prompting research into post‑quantum signatures and protocol changes. Success could preserve asset security, while delays risk vulnerability and market confidence erosion.
The Foundation wants the network protected before a quantum computer capable of breaking today's cryptography could plausibly arrive, and says upcoming upgrades will be judged against that clock.
