The Defiant reports that Stacks has conducted a mainnet vault withdrawal using a Lamport one-time signature. This test aims to explore post-quantum signature technology. However, it does not upgrade standard sBTC wallets or the Bitcoin backing the token, indicating that the current infrastructure remains unchanged despite the test.
