Europol today identified crypto wallets as a key risk in quantum attacks.
The report makes one thing clear: blockchain hashes and mining can withstand quantum attacks, but wallets cannot. If a quantum computer gets hold of a public key that has already been made public, it can derive the private key and steal the coins. Once a public key has appeared on-chain, there’s no taking it back.
The implications for crypto are direct. 70% of Bitcoin’s coins are held in old-style addresses from the early days, whose public keys have long been exposed. Migrating them would mean changing the signature on every future transaction, increasing transaction sizes by 10 to 120 times and driving up fees while slowing confirmations. Whales holding large amounts in these old addresses need to decide over the next three years whether to migrate proactively or wait until something goes wrong.
Get the signature-verification script running this weekend, and keep a close eye on private-key flows from old addresses holding 70% of the coins. With a three-year window, migrating proactively in one go will cost 10 to 120 times less in transaction size than trying to fix things after an incident.
