Steal Bitcoin, Lose Your Own BTC? Developer Floats Three Defenses Against Quantum Attacks

Brief

By Dextape Desk · November 6, 2026

Cory Fields, a developer affiliated with MIT's Digital Currency Initiative, has floated three ways to deter quantum thieves. He shared them on a developers' mailing list as exploratory concepts, saying a soft fork could make them possible. Quantum Landmines would let holders hide a cryptographic proof in a small quantum-safe output before quantum machines can break current cryptography. If a vulnerable output were later stolen, the thief would have to lock matching quantum-safe bitcoin as collateral for a set period such as 30 days, and the owner could claim it by revealing that proof. The Staked Auction lets holders stake quantum-safe coins in advance to bid on exposed holdings. Fields said collateral ratios, auction rules and recovered-fund handling remain unresolved.

Why it matters: It shows Bitcoin developers are weighing ways to make quantum theft of exposed coins costly, a design question the article says is still open.
