Shor\u2019s algorithm, a quantum computing technique, is theoretically capable of compromising the elliptic-curve cryptography underpinning most major <span>blockchain<\/span> networks.<\/p>\n<p>The <span>BNB<\/span> Smart Chain proposal replaces traditional transaction signatures with ML-DSA-44, a lattice-based signature algorithm standardized under NIST\u2019s FIPS 204 framework. Consensus-layer vote aggregation is simultaneously upgraded using pqSTARK proofs.<\/p>\n<p>The changes significantly improve theoretical resistance to quantum attacks, but they also expose the practical limitations of today\u2019s <span>blockchain<\/span> infrastructure.<\/p>\n<p>Under the new framework, average transaction size rises from roughly 110 bytes to about 2.5 kilobytes. At the network level, block sizes increase from around 130 kilobytes to nearly 2 megabytes under equivalent transaction loads.<\/p>\n<p>In testing, throughput dropped between 40% and 50% depending on workload conditions. Cross-region performance saw the sharpest impact as larger blocks required more time to propagate across geographically distributed validator <a href=\"http:\/\/www.bitcoin.com\/get-started\/what-is-a-bitcoin-node\/\" class=\"lar_link lar_link_outgoing\" target=\"_blank\" rel=\"noopener noreferrer\">nodes<\/a>.<\/p>\n<p>Even so, developers said the results demonstrate that quantum-safe migration is technically feasible using current standards and infrastructure.<\/p>\n<p><a href=\"https:\/\/static.news.bitcoin.com\/wp-content\/uploads\/2026\/05\/bnb-smart-chain-shows-quantum-safe-crypto-works-despite-50-throughput-drop_nwmk.png?X-Amz-Content-Sha256=UNSIGNED-PAYLOAD&amp;X-Amz-Algorithm=AWS4-HMAC-SHA256&amp;X-Amz-Credential=AKIARQKIT2TMGZBKV2L6%2F20260519%2Fus-east-1%2Fs3%2Faws4_request&amp;X-Amz-Date=20260519T130810Z&amp;X-Amz-SignedHeaders=host&amp;X-Amz-Expires=600&amp;X-Amz-Signature=2e0cf490facf9606eb6ac474a948e9231f52ef4d5500cba1b5f392bbfdd2ff95\"><\/a><\/p>\n<h3>Quantum Test Retains Compatibility With Existing <span>Blockchain<\/span> Architecture<\/h3>\n<p>One of the key breakthroughs came at the consensus layer. Although individual post-quantum signatures are substantially larger than existing cryptographic signatures, aggregation through pqSTARK compression reduced validator communication overhead to manageable levels.<\/p>\n<p>In one example, six validator signatures totaling 14.5 kilobytes were compressed into a proof of roughly 340 bytes, producing a compression ratio of approximately 43-to-1.<\/p>\n<p>The proposal also preserves compatibility with existing <a href=\"http:\/\/www.bitcoin.com\/get-started\/what-is-a-blockchain\/\" class=\"lar_link lar_link_outgoing\" target=\"_blank\" rel=\"noopener noreferrer\">blockchain<\/a> tooling. Wallet addresses remain unchanged at 20 bytes and continue to rely on keccak-256 formatting, meaning most wallets, SDKs, and RPC infrastructure would not require significant redesign.<\/p>\n<p>Developers selected ML-DSA-44 over larger security variants because of efficiency concerns. While stronger versions offer higher theoretical protection, they also produce substantially larger signatures that would further reduce throughput. Researchers concluded that ML-DSA-44 provides a sufficient security margin given estimates that cryptographically relevant quantum computers remain at least a decade away.<\/p>\n<p>The work reflects a growing industry shift toward long-term cryptography, as <a href=\"http:\/\/www.bitcoin.com\/get-started\/what-is-a-blockchain\/\" class=\"lar_link lar_link_outgoing\" target=\"_blank\" rel=\"noopener noreferrer\">blockchain<\/a> networks evaluate how existing architectures would perform under quantum-resistant models.<\/p>\n<\/p><\/div>\n<p><a href=\"https:\/\/news.bitcoin.com\/bnb-smart-chain-shows-quantum-safe-crypto-works-despite-50-throughput-drop\/\">Source link <\/a><br \/>\n<br \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>(Originally posted on : Bitcoin News ) Key Takeaways BNB Smart Chain tested NIST-backed ML-DSA-44 to prepare for quantum threats.
