Bitcoin developer proposes ‘landmines’ to make quantum thieves lose their own BTC

Grade Bbullish AI signal$BTC

A Bitcoin Core developer has proposed “quantum landmines” that would force potential quantum thieves to risk their own BTC as collateral before attempting to steal vulnerable coins. Cory Fields’ thought experiments include locking the attacker’s collateral alongside targeted bitcoin for a waiting period, allowing legitimate owners to reveal hidden proof and reclaim their holdings plus the penalty. The proposal could discourage future quantum attacks, but implementation remains uncertain and would require quantum-safe wallets, unwritten enforcement rules and additional collateral from honest holders.

Legitimate owners could reclaim stolen BTC and claim attackers' collateral by revealing hidden proof of ownership.
Provides a potential alternative to freezing vulnerable bitcoin holdings.

Bearish strength: 35/100

Honest holders would also need matching BTC collateral to move vulnerable coins.
Lost or inactive coins cannot benefit from the primary landmine mechanism.
The proposals remain thought experiments requiring quantum-safe wallets and unwritten enforcement rules.

Cory Fields proposes quantum landmines to deter Bitcoin theft

Bitcoin Core developer Cory Fields has proposed “quantum landmines,” a thought experiment that would require would-be quantum thieves to post collateral before attempting to steal vulnerable BTC. The concept could reward honest behavior or forfeit collateral after attempted theft, but depends on quantum-safe wallets and unresolved soft-fork rules; approximately 7.1 million BTC, or 35% of circulating supply, currently sit in wallets with exposed public keys. If developers refine the proposal and reach community agreement, it could add an economic deterrent to Bitcoin’s quantum-security defenses, though no implementation is currently underway.

US Fintech Weekly: Fiserv Bounces Post-Earnings, Crypto Brokers Suffer, And Federal Agencies Prepare Innovation Guidelines

Fiserv shares surged nearly 13% after earnings, while crypto-linked stocks Robinhood and Coinbase headed for a sixth consecutive weekly decline amid Bitcoin weakness and growing regulatory uncertainty. Fiserv benefited from an earnings beat and a new $500 million share buyback authorization, while six federal agencies are preparing fintech innovation guidelines ahead of a November 15 deadline. Stronger regulatory oversight under Democratic congressional control could pressure crypto platforms, although continued institutional integration may limit the sector's downside.

Crypto ally French Hill wins reelection but set to lose House chair

Crypto-friendly Republican French Hill won reelection in Arkansas but is expected to lose his House Financial Services Committee chairmanship after Democrats gained control of the House. Hill sponsored the CLARITY Act and supported the GENIUS Act, while Democrat Maxine Waters is the leading contender to replace him as chair; crypto-backed PACs spent more than $176 million during the election cycle. The leadership change could increase regulatory scrutiny and create uncertainty around the future of US crypto legislation.
