In the ever-evolving world of cryptocurrency, a new threat has emerged that could potentially upend the very foundation of digital currencies - quantum computing. As macro worries tied to the Iran conflict loom large, this cutting-edge technology poses a significant threat to the security of Bitcoin and other cryptocurrencies. But amidst this turmoil, one token stands out as a beacon of hope: QRL, the native cryptocurrency of the Quantum Resistant Ledger.

Why it matters

Quantum computing has the potential to break the cryptography that underpins many cryptocurrencies, including Bitcoin. This vulnerability could compromise the core tenets of crypto, namely 'trust the code' and the 'hard money' value proposition. Projects like QRL, which use quantum-safe cryptography, could draw more attention and potentially gain market value as concerns about quantum threats grow.

The details

Quantum computing, which leverages the principles of quantum mechanics to perform calculations, has the potential to break the cryptography that secures the Bitcoin blockchain. Research suggests that a system with around 26,000 qubits could break the encryption standard that secures the Bitcoin and Ethereum blockchains in about 10 days. In contrast, QRL uses a quantum-safe signature scheme called XMSS (eXtended Merkle Signature Scheme), which is designed to be resistant to quantum attacks.

  • According to a paper from Google, breaking the Bitcoin blockchain's cryptography with quantum computers could require fewer than 500,000 qubits, a fraction of previous estimates.
  • A separate paper by Caltech and quantum startup Oratomic suggests that a system with around 26,000 qubits could break the encryption standard that secures the Bitcoin and Ethereum blockchains in about 10 days.

What they’re saying

“The emergence of quantum computing as a potential threat to cryptocurrencies is a significant development that could shape the future of the industry.”

— Greg Kuvalis, Author

“As the technology matures and becomes more widely adopted, we may see a shift towards quantum-safe cryptocurrencies, which could provide a new level of security and trust in the digital currency ecosystem.”

What’s next

The judge in the case will decide on Tuesday whether or not to allow Walker Reed Quinn out on bail.

The takeaway

This case highlights growing concerns in the community about repeat offenders released on bail, raising questions about bail reform, public safety on SF streets, and if any special laws to govern autonomous vehicles in residential and commercial areas.
