Cory Fields Proposes Quantum Traps for Future Bitcoin Theft
Bitcoin Core developer Cory Fields has proposed concealed “quantum landmines” designed to punish attackers and potentially recover stolen bitcoin.
Bitcoin Core developer Cory Fields has proposed concealed “quantum landmines” designed to punish attackers and potentially recover stolen bitcoin. Bitcoin (BTC) is trading at ₹70,22,898 ($74,768.00), up 0.4% since this brief published. This is an original Token Times brief based on reporting by Bitcoin.com, with live market data added, as of Tue, 10 Nov 2026 05:45:02 UTC.
The proposal offers a cryptographic, rather than custodial, response to a future quantum attack on bitcoin. Its significance depends on whether the community can agree on and deploy a workable mechanism before such threats become practical.

- Cory Fields Proposes Quantum Traps for Future Bitcoin Theft — this brief
Bitcoin Core developer Cory Fields introduced an unconventional proposal for defending bitcoin against future quantum attacks. His “quantum landmines” would be concealed within the system and could enable bitcoin holders to recover coins taken by an attacker while also capturing the attacker’s collateral. Bitcoin.com reported the proposal on Nov. 4, 2026.
The concept treats attempted theft as something that could impose costs on the perpetrator rather than simply transferring bitcoin irreversibly. Coverage describes the landmines as a proposed mechanism; the available report does not provide technical specifications, implementation details or evidence that the proposal has been adopted or deployed.
The proposal comes as bitcoin faces continued discussion of quantum-computing risks. Fields’s approach focuses on making a future quantum-enabled theft more difficult and potentially recoverable, using the structure of bitcoin itself rather than relying on a third party to intervene.
Live market data shows bitcoin at $74,465, down 0.37% over 24 hours and 2.83% over seven days. Its market capitalization is $1.5 trillion within a total crypto market worth $2.55 trillion, where the overall market is flat. The Fear & Greed index stands at 32, placing sentiment in the “Fear” range; no market data supplied attributes the proposal itself to bitcoin’s recent performance.

Will Bitcoin dip to $70,000 by December 31, 2026?
Crowd-implied probability on Polymarket, ₹8.44M 24h volume, resolves Jan 1 — snapshotted when this brief published (Nov 10 04:05 UTC). A market price reflects what traders collectively expect; it is not a forecast by Token Times and will have moved since. View the market ↗
At today's peer-to-peer rate, 1 BTC ≈ ₹7.48M (about $74,768.00), up 0.6% over 24 hours. The rupee itself trades about 6.5% above the official rate on the P2P market, so a Indian buyer's effective cost differs from the headline dollar price.

Cory Fields Proposes Quantum Traps for Future Bitcoin Theft — questions & answers
Who proposed the quantum landmine defense?
Longtime Bitcoin Core developer Cory Fields introduced the proposal, according to Bitcoin.com.
What would the quantum landmines do?
They are intended to help bitcoin holders reclaim stolen coins while confiscating collateral belonging to the attacker.
Are the quantum landmines already deployed?
The available coverage presents them as a proposed defense and does not report adoption or implementation.
How much is 1 Bitcoin worth in rupee today?
About ₹7.48M at the live peer-to-peer (P2P) USDT rate, which is what Indians typically trade at — equivalent to roughly $74,768.00. The rupee price moves with both BTC's US-dollar price and the USDT/INR rate; use our Bitcoin in rupee page for any amount.
