Proof Of Keys Day And Quantum Computing

When Satoshi Nakamoto mined the genesis block 13 years ago today, giving rise to the Bitcoin blockchain, he sparked a cryptographic revolution — you could store your wealth behind personal private keys.

Recognized every January 3, Proof Of Keys Day is an opportunity to reflect on that breakthrough by ensuring that you hold your private keys. In recent years, Bitcoiners have celebrated this day by taking their bitcoin off of exchanges.

At Casa, we help Bitcoiners take self custody of their keys, and we’ve found that some education is required to use this power effectively. This year, we’re taking Proof Of Keys Day a step further by calling out a threat on the horizon and explaining why we should act now to keep our keys as robust as ever. That threat is quantum computing.
