Quantum Computing Could Benefit the Bitcoin Blockchain, Blockstream Founder Argues

Dec 23, 2024 at 10:11 am

Despite widespread concerns about the scary potential of quantum computing, the Blockstream founder has argued it will actually benefit the blockchain's security.

Quantum Computing Could Benefit the Bitcoin Blockchain, Blockstream Founder Argues

Google recently made a breakthrough in quantum computing technology that has left the crypto community spooked.

The major tech advancement came with a remarkable increase in the computational power of chips, leading some to believe that hackers could now attack the cryptographic keys that secure Bitcoin.

If dormant wallets, like Satoshi’s, were liquidated, it could cause a mass destabilising event for the coin.

But, according to prominent blockchain developer Adam Back, quantum computing might actually help secure the protocol.

Prominent blockchain developer Adam Back has argued that Bitcoin can leverage recent upgrades like Taproot to become quantum computing resistant without needing to make drastic changes to the blockchain.

Responding to an X (formerly Twitter) thread, Back suggested that a Bitcoin Improvement Proposal to defend against quantum computers like Willow may not be needed.

maybe not needed. you can be quantum ready using a taproot leaf committing to a future soft-forkable PQ signature opcode, and a hash-based key scheme. then you can migrate to that PQ ready Schnorr signature, while only paying current signature sizes. then people will calm down.

Okay, that’s a lot of complicated words.

As simply as possible, Back is implying that Bitcoin could leverage the Taproot leaf upgrade and create an operation code designed to stand up against quantum computing attacks.

By ensuring it is “soft-forkable”, the code could then be updated intermittently depending on flaws exposed by quantum computing without requiring a complete overhaul of the Bitcoin blockchain.

Then, moving to an updated Schnorr signature (a more efficient and secure way of digitally signing transactions on the blockchain) could help defend the protocol to an ever greater level.

The current state of quantum computing is decades away from actually posing a threat to Bitcoin’s blockchain.

But, the fact that this threat exists could spur developers into action, leading them to create a quantum-resistant, inherently more secure network.

And because the industry has several years before a compromise could become a reality, Bitcoin can be well-prepared for a post-quantum world while other networks suffer.

Essentially, he’s implying this is an opportunity for Bitcoin to be proactive, rather than reactive.
