Daisugi v0.1 launches as post-quantum Ethereum testnet

September 25, 2026

Researcher asanso announced Daisugi v0.1, a post-quantum Ethereum testnet using hash-based SPHINCS signatures with non-native account abstraction. Announced as "HABEMUS TESTNET," the testnet is an early experiment in quantum-resistant Ethereum accounts, with credit given to RIVA Labs and Giulio Rebuffo for the work.

The launch comes as Ethereum's post-quantum roadmap leans on account abstraction to let users migrate signature schemes without a protocol-wide consensus change. The announcement was amplified by the Ethereum account on X.
