Sei Network introduces SIP-5, creating a pathway for every account to upgrade into quantum-secure protection if future quantum threats emerge

ML-DSA signatures clock in at 2.4KB against secp256k1's 64 bytes — 37x the cargo weight on a chain whose whole thesis be pushing volume through fast. Ye can offer every account an opt-in pathway, but a network where most haven't upgraded yet isn't a security posture — it's a targeting map, and quantum attackers sail straight for the unprotected majority. If Sei ever mandates universal adoption, those throughput benchmarks need rerunning against post-quantum signature loads before anyone calls it solved. If critical mass doesn't upgrade before the threat arrives, the protection only works for the minority that moved early. 🦑
