Quantum Attack Game Theory

A Delving Bitcoin thread in which Jameson Lopp introduces his essay Quantum Attack Game Theory, an attempt to catalog systematically what might happen if a cryptographically relevant quantum computer appeared — pushing back on the common assumption that it would cause only "temporary market volatility."

The thread argues the outcome depends on attacker incentives and the network's response, not just the existence of the hardware, and the replies dig into the game theory of a quantum-capable miner choosing between stealing exposed coins and mining honestly, including the expected-value math of attempting a private reorg. The full essay lives on Lopp's blog, linked from the post.
