- QuFi launched a post-quantum verification platform featuring a Bitcoin testnet proof, incorporating the ML-DSA-65 cryptographic standard also being piloted by banks and regulators
- Jonas Nick announced the BIP SHRINCS proposal on Aug. 26, with Blockstream researchers publishing a Bitcoin Improvement Proposal for the experimental post-quantum signature scheme designed to reduce the size and performance costs of quantum-resistant signatures
- SHRINCS uses stateful signatures requiring wallets to track previously used signing keys, remains in an early stage without a completed security proof, and adds complexity and potential user failure modes
- Banks and regulators across Europe, the Middle East and Asia joined a pilot testing post-quantum wallets and onchain transfers using ML-DSA-65, the same standard incorporated into QuFi's platform
- The Ethereum Foundation dropped the Poseidon hash function from its planned post-quantum architecture in favor of established alternatives such as SHA or BLAKE
Why it matters: The fragmented approach—QuFi's commercial platform, Blockstream's experimental SHRINCS proposal, Ethereum abandoning Poseidon—shows the crypto industry is still searching for a standardized post-quantum path, leaving Bitcoin holders with uncertain migration timelines as stateful schemes remain unproven while regulators in three continents already pilot ML-DSA-65 wallets.
