Post-Quantum Cryptography Institution BTQ Announces Bitcoin Post-Quantum Algorithm Solution Bitcoin Quantum

BlockBeats News, January 12th, according to Coindesk, the post-quantum cryptography firm BTQ Technologies (BTQ) recently unveiled a scheme to protect the Bitcoin blockchain, called "Bitcoin Quantum," a permissionless forkless testnet that reportedly can withstand quantum challenges.

BTQ's partnership lead, Chris Tam, stated that Bitcoin Quantum is a publicly executable network where miners, developers, researchers, and users can stress-test quantum transactions, revealing real-world trade-offs before the mainnet upgrade discussion becomes urgent. The system includes a block explorer and mining pools, providing real-time accessibility.

Tam explained that in August 2024, the post-quantum algorithm known as "Dilithium" (officially named the Lattice-based Digital Signature Algorithm ML-DSA) completed standardization in the United States, the same technology adopted by the Bitcoin Quantum network. This algorithm has not been widely used in fast-paced innovation fields like cryptocurrency, mainly due to its high operational costs. In contrast to the digital signatures used for each blockchain transaction or even a WhatsApp message, the data scale of post-quantum algorithms is at least 200 times larger. Therefore, while there are methods to address quantum risks, they also introduce challenges, particularly in terms of performance and cost efficiency during large-scale deployments.
