Building Giga: What Quantum Computing Means for High Performance Chains
By Ben Marsh of Sei Labs
TL;DR: The Quantum Scaling Challenge for High-Performance Chains
Post-quantum security is a throughput problem, not just a math problem. Upgrading Sei Giga (200k TPS) to standard NIST post-quantum signatures (ML-DSA) would bloat bandwidth requirements to 0.48–1.57 GB/s, breaking the
