BTQ Technologies has unveiled the Bitcoin Quantum testnet, a permissionless fork designed to protect the Bitcoin blockchain from quantum threats. This initiative allows miners, developers, and researchers to conduct stress tests on quantum transactions, providing insights into potential trade-offs before any mainnet upgrades are considered. The testnet includes a block explorer and mining pool for immediate use. The Bitcoin Quantum Network utilizes the "Dilithium" post-quantum algorithm, standardized in the U.S. in August 2024. Despite its potential, the algorithm faces challenges due to high operational costs and large data size requirements, which are at least 200 times larger than current digital signatures. These factors pose significant hurdles for widespread adoption in the fast-evolving cryptocurrency sector.
