PANews reported on April 1st that Satoshi Nakamoto discussed quantum computing in a forum post in 2010. Regarding the risk that quantum computing might crack signature algorithms, he stated that if this were to happen gradually, a software upgrade could transition to a more secure signature scheme. When users first run the upgraded software, they can re-sign all assets using the new signature algorithm (i.e., create a transaction that sends the assets to themselves and uses a stronger signature).
Earlier yesterday, Google stated that most blockchains rely on the vulnerable ECDLP-256 protocol, making quantum migration resistance an urgent priority .
