Ethereum Core Developers Draft a Quantum Resistant Upgrade Proposal

According to Arzdigital, published Tuesday, Shahrivar 3, 1405 (August 25, 2026), Ethereum's core developers have drafted a proposal to upgrade the network's Deposit Contract in preparation for the "post-quantum era." The proposal, drafted by researchers including Kevaundray Wedderburn, is built on the EIP-7685 standard and would let the network eventually replace its current BLS digital signature scheme with algorithms resistant to quantum computers.

According to the report, unlike the current system, the new contract would support public keys and signatures of variable length, letting validators use a range of cryptographic schemes, while the existing system remains active for backward compatibility. The proposal is currently only at the draft stage on GitHub and must clear security review, technical analysis by client teams, and approval at Ethereum developer meetings before any adoption in a mainnet upgrade.
