Will Quantum Computers Threaten Blockchains?

The video discusses quantum computers, their potential to outperform traditional computers, and their implications for blockchain security. Quantum computers operate at the particle level, using qubits that can exist in multiple states simultaneously, offering significant computational power. However, they pose a threat to current encryption methods, including those used in blockchains. Solutions like quantum-safe encryption and quantum blockchains are being explored. While quantum computers are not yet commercially available, efforts are underway to develop security measures before they become a threat.
