BNB Chain Publishes Research Report Exploring Post-Quantum Cryptography Migration Path for BSC

[PRESS RELEASE – Dubai, UAE, May 14th, 2026]

14th of May, Dubai: BNB Chain, the leading L1 blockchain ecosystem, has published a new research report evaluating how BNB Smart Chain (BSC) could migrate core cryptographic systems to post-quantum alternatives in the future.

The report explores the implementation and performance implications of replacing traditional blockchain cryptography with quantum-resistant approaches, including ML-DSA-44 transaction signatures and pqSTARK aggregation for validator consensus.

While quantum computing is not yet capable of breaking production blockchain cryptography in real-world systems, the research reflects a forward-looking approach to infrastructure resilience and long-term network security.

The report evaluates several core areas of the BSC stack, including:

• Post-quantum transaction signature schemes
• Validator signature aggregation
• Transaction verification flows
• Public key storage
• Cross-region network performance under increased data loads

One of the key findings was that post-quantum readiness is technically achievable today, but comes with significant scalability trade-offs.

In testing:

• Transaction size increased from 110 B to ~2.5 KB
• Block size increased from ~110 KB to ~2 MB
• Native transfer TPS decreased from 4,973 to 2,997

The report found that the primary bottleneck was not signature verification performance itself, but the increase in transaction and block sizes, which created additional network propagation overhead across regions.

At the same time, pqSTARK aggregation remained highly efficient. Validator signatures were compressed at roughly 43:1, helping keep consensus-layer overhead manageable despite larger signature sizes.

The report also notes that several areas remain outside the current scope of evaluation, including post-quantum replacements for P2P handshakes and KZG commitments, both of which would require broader ecosystem coordination and additional research.

BNB Chain stated that the work is intended as research and evaluation, rather than a response to any immediate security threat.
