BNB Chain developers successfully deployed ML‑DSA‑44 signatures and pqSTARK aggregation on the live newtork, proving that quantum‑resistant upgrades can coexist with existing wallets, SDKs and RPC interfaces. The experiment , carried out on the Binance Smart Chain (BSC) infrastructure, demonstrated seamless user‑facing compatibility while exposing a steep drop in performance metrics.

ML‑DSA‑44 and pqSTARK Integration Leaves Wallets Unchanged

According to the source report,the new cryptographic schemes were added without requiring users to switch wallets or alter address formats. This continuity means that billions of BNB holders could theoretically adopt post‑quantum security without the friction of migrating assets or learning new tools.

Throughput Slumps Nearly 40% After Quantum Upgrade

Performance pressure emerged as larger cryptographic payloads strained the network; native transfer throughput fell from 4,973 transactions per second (TPS) to 2,997 TPS ,a reduction of almost 40%. gas throughput also dropped roughly 50%, and block sizes swelled to about 2 MB—an eighteen‑fold increase—leading to longer propagation delays despite satble finality.

Scalability Becomes the New Bottleneck for Post‑Quantum Migration

Developers noted that the primary obstacle shifted from compatibility to scalability. Heavier blocks and higher storage demands threaten to raise transaction costs and slow network movement, suggesting that future quantum‑resistant upgrades may require substantial infrastructure upgrades.

What Remains Unclear About Long‑Term Quantum Migration?

The source leaves several questions unanswered: How will the network’s bandwidth and storage requirements evolve if quantum‑resistant signatures become standard? Will layer‑2 solutions or protocol redesigns offset the observed slowdown? And what timeline does Binance envision for a full‑scale rollout beyond experimental phases?
