BTQ Technologies (BTQ), a professional institution in post-quantum cryptography, recently announced a solution to protect the Bitcoin blockchain called "Bitcoin Quantum," a permissionless fork testnet that is claimed to be able to withstand quantum challenges. Chris Tam, head of BTQ partnerships, stated that Bitcoin Quantum is a publicly accessible network where miners, developers, researchers, and users can stress test quantum-resistant transactions and reveal the trade-offs in actual operation before the mainnet upgrade discussions become urgent. The system includes a block explorer and mining pool, providing instant accessibility.
