BNB Chain Releases Research Report, Exploring the Path to Post-Quantum Cryptography Migration for BSC
BNB Chain has released a new research report exploring a potential migration path for BNB Smart Chain (BSC) to post-quantum cryptography (PQC). The study assesses the feasibility and performance impact of replacing traditional blockchain cryptography with quantum-resistant alternatives, aiming to ensure long-term network security.
Key areas evaluated include post-quantum transaction signatures (proposing ML-DSA-44), validator signature aggregation, transaction verification, public key storage, and cross-regional network performance under increased data loads. A major finding is that while technically feasible now, achieving PQC-readiness involves significant scalability trade-offs. Test data showed transaction size increased from ~110 bytes to ~2.5 KB, block size grew from ~110 KB to ~2 MB, and native transfer TPS decreased from 4,973 to 2,997. The primary performance bottleneck was identified as increased network transmission overhead due to larger data volumes, rather than the signature verification process itself.
Notably, the pqSTARK aggregation technique proved efficient, compressing validator signatures at a ~43:1 ratio, which helps manage consensus layer overhead. The report clarifies this is a research-oriented exploration, not a response to an imminent threat, and notes that areas like P2P handshakes and KZG commitments require further study and broader ecosystem coordination.
