"Not your keys, not your coins."
I posit that the corollary to this principle is:
'Your keys, only your coins.'

A quantum capable entity breaks the corollary of this foundational principle. We secure our bitcoin with the mathematical probabilities related to extremely large random numbers. Your funds are only secure because truly random large numbers should not be guessable or discoverable by anyone else in the world.

It seems almost inevitable, that at some point quantum computing could reach the capacity to break current cryptographic standards, so the question is, what do we do about it? Do we allow the first entities with a powerful quantum computer, the already wealthy and powerful, attack the keys to millions of BTC and dominate the economic destiny of Bitcoin? Or should this be treated like a vulnerability? A bug in the code. Where we set a date to deprecate the old signatures, and burn the coins that were lost to vulnerable keys? The answer might not be as simple as you first suspect, Jameson Lopp makes a solid case in today's article.
