BSC’s quantum defense works. The trade-off is 40% slower transaction throughput.
BSC successfully tested quantum-resistant cryptography, but this resulted in a 40% decrease in transaction throughput. The larger signatures required for quantum safety increased data loads, creating a bottleneck for user transactions. Other blockchains are also exploring quantum defenses, highlighting the trade-off between security and speed.
- ▪BSC's quantum-security test showed a 40% drop in transaction throughput due to larger data signatures.
- ▪The test replaced ECDSA and BLS12-381 signatures with quantum-resistant alternatives.
- ▪Other blockchains like Bitcoin, Ethereum, and TRON are pursuing different strategies for post-quantum security.
