Today’s BTC news: A Bitcoin Core developer named Fields has proposed a “quantum landmine” mechanism to penalize BTC thieves. The concept requires attackers to deposit 1 BTC as collateral in a quantum-safe wallet to steal 1 BTC. Both funds are locked for 30 days. During this period, the legitimate holder can generate a hidden proof of ownership. If the thief attempts to move the BTC, both the stolen coins and the collateral are frozen. The holder can then reveal the proof to reclaim their BTC and claim the thief’s collateral. Thieves cannot know which addresses are at risk before transferring funds. This BTC update introduces a new layer of security for BTC holders.

According to Mars Finance, under Fields' proposal, an attacker attempting to steal 1 BTC would be required to post an additional 1 BTC as collateral from a quantum-safe wallet; both funds would be locked for a waiting period, such as 30 days. Before quantum attacks become feasible, the original owner could create a quantum-safe "mine" containing a hidden proof of ownership. If the thief later attempts to move the vulnerable coins, both the stolen BTC and the attacker’s collateral would be locked. The owner could disclose the proof during the waiting period to reclaim their BTC and claim the attacker’s collateral as a penalty. The attacker cannot determine in advance which addresses contain traps before committing their funds.
