🐦 What if the real quantum threat to crypto is not the math — but the migration?
CZ says there is no need to panic at a high level, because crypto can upgrade to quantum-resistant algorithms.
But he also makes the harder point: in a decentralized world, upgrades are never simple.
There will likely be fights over which algorithms to adopt, some networks may split into forks, dead projects may never upgrade at all, and new code could introduce fresh bugs and vulnerabilities.
For self-custody users, the challenge is even more personal.
They may need to move funds into new wallets, which turns quantum security into a real user-level migration problem, not just a protocol debate.
Then comes the biggest philosophical question of all: Satoshi’s coins.
CZ said that if those coins move, it would suggest Satoshi is still around, but if they do not move within a certain period, one possible idea would be to lock or effectively burn those addresses so they do not go to the first hacker who cracks them.
His bottom line is still optimistic.
Encryption is easier than decryption, more computing power is ultimately a good thing, and crypto can survive even in the quantum era.
So maybe the future is not “crypto vs quantum.”Maybe it is “crypto must evolve faster than the threat.”
