⚡️🧮 NEW - According to Google researchers, it could be 20 times easier than expected for quantum computers to break #Bitcoin.

According to them, decrypting RSA, the technology that secures crypto wallets, requires far fewer quantum resources than previously thought.

Craig Gidney, researcher at Google Quantum:

"I estimate that a 2048-bit RSA integer could be accounted for in less than a week by a quantum computer with less than a million noisy qubits".

"This is a 20-fold decrease in the number of qubits compared to our previous estimate."

To put this into context, IBM's Condor (the most powerful quantum computer to date) achieves 1,121 qubits, while Google's Sycamore operates with 53.

IBM is planning a 100,000-qubit quantum computer by 2033, in partnership with the University of Tokyo and the University of Chicago.

This is still a long way from the 1 million qubits mentioned.

Attention bait by Google.(TM)

Where is RSA used in Bitcoin?

Bitcoin does not use RSA in its core cryptographic design. Its security relies entirely on Elliptic Curve Cryptography (ECC) and hash functions (SHA-256 and RIPEMD-160). Here’s why RSA is absent and what Bitcoin actually uses:

Private/Public Key Pairs:

Bitcoin uses the Elliptic Curve Digital Signature Algorithm (ECDSA) with the secp256k1 curve. Private keys are 256-bit numbers, and public keys are derived via ECC. This differs from RSA, which relies on large prime factorization.

Address Generation:

Public keys are hashed (SHA-256 + RIPEMD-160) to create Bitcoin addresses. This process does not involve RSA.

Transaction Signing:

Transactions are signed with ECDSA, not RSA. Nodes verify signatures using the sender’s public key without requiring RSA-based encryption.

(little fast AI knowledge for you :D)

Ou they talk about it at hte end of article - it is just click bait title ..

That's why I always indicate the source of my publications. Thanks nostr:npub158x7tu26f0uvm7mkzavp95xj99pav7pqrh7f64ldm62f920mcklq9h76wm

Quantum fud 😴

WHEN BITCOIN TANKS

So they have to up 1000x to 20000x their current capacity to break Bitcoin. How’s that 20 times easier? 🤔

Ohhh noo not the noisy quibits!

Preparing for Conference dump ?

Even if it could be done (with massive computing power), you've broken into a single wallet...

Big juicy nothing-burger.

There are already solutions. At most you go back with a hardfork 🤷‍♂️
