And since we are a little scared, let's scare ourselves completely! Nah, just kidding 😅

Can a quantum computer hack Bitcoin? đŸ–„ïžâšĄ

Bitcoin is super secure thanks to its cryptography, which has two pillars:

🔑 Digital signatures (ECDSA): only you can spend your 04541455255.

🔒 SHA-256: protects transactions and is key for mining.

Where is the danger?

👉 In the future, a powerful quantum computer could derive your private key from your public key, something impossible for today's computers.

That would mean they could steal BTC from wallets that have already revealed their public key on the blockchain.

⚠ This is especially risky if you use the same address multiple times or if your public key has already been exposed. But if you only use the hash, you're safer.

When could this happen?

Today, there is no such super quantum computer.

But if that monster arrives, the Bitcoin world will have to update quickly to stay safe.

There are already ideas to protect us, such as:

đŸ›Ąïž Post-quantum cryptography

đŸ›Ąïž Changes in addresses

đŸ›Ąïž New types of stronger signatures
