BNB Smart Chain post-quantum roadmap weighs data overhead
The post BNB Smart Chain post-quantum roadmap weighs data overhead appeared on BitcoinEthereumNews.com. BNB Smart Chain post-quantum planning is no longer a theoretical security exercise. BNB Chain has published a technical report mapping how BNB Smart Chain could migrate toward post-quantum cryptography, and the early results point to a blunt trade-off: stronger cryptography comes with much heavier data overhead. That tension runs through the entire proposal. On one side, the report aims to prepare the network for future quantum threats. On the other, the tests show that much larger signatures can drag down throughput even when consensus behavior holds up relatively well. The picture is unusually clear for a blockchain infrastructure study. BNB Chain is not just floating abstract ideas. It is laying out specific replacements for transaction signatures and validator vote aggregation, then showing what those choices do to block size, latency, and throughput.
