Ethereum Foundation researcher says quantum readiness at 20%

Antonio Sanso, a researcher at the Ethereum Foundation, recently provided an update on Ethereum's progress toward quantum resistance at the ETHCC blockchain conference. He stated that current digital signature methods could be threatened by quantum computers by the mid-2030s, adding that Ethereum's preparations to counter this are 20% complete. The foundation plans to implement a full response system through an upgrade scheduled between 2028 and 2032. Sanso noted that the biggest challenge is signature data size, as quantum-resistant signatures are more than 10 times larger than existing ones, which significantly increases verification costs. He added that a solution to this issue has been proposed and that related research has been conducted on a bi-weekly basis since February.
