PQC keys are significantly larger than classical equivalents. ML-DSA-65 signatures are 3,309 bytes vs ECDSA’s 72 bytes — 46x larger. This creates blockchain scalability challenges that BMIC’s architecture specifically addresses.
ML-KEM-768 public keys: 1,184 bytes vs ECDH’s 32 bytes (37x). ML-DSA-65 signatures: 3,309 bytes vs ECDSA’s 72 bytes (46x). SPHINCS+ signatures: up to 49,856 bytes (692x). These sizes directly impact blockchain transaction costs, block space, and network throughput.
Bitcoin’s 1MB blocks can fit ~2,700 ECDSA transactions. With ML-DSA signatures, capacity drops to ~60 transactions per block. This is why Bitcoin hasn’t adopted PQC — the engineering trade-offs are severe for block-space-limited chains.
BMIC handles PQC’s size overhead through its L2 signature-hiding layer. PQC signatures are verified within the smart account system without being stored on the Ethereum base layer. The on-chain footprint remains minimal while full quantum security operates behind the scenes. This is why architecture matters more than algorithm selection.
Will PQC signatures get smaller? FN-DSA (Falcon) offers 666-byte signatures — much closer to ECDSA. As PQC research continues, further optimisations are expected. BMIC’s adaptive architecture can incorporate smaller algorithms as they become available.
Every day you wait, more of your public keys are being harvested. Intelligence agencies are running Harvest Now, Decrypt Later operations right now. Your wallet’s ECDSA keys are being collected and stored for the day quantum computers can crack them. That day is approaching faster than anyone expected.
BMIC’s presale is live — but it won’t last forever. With 50 phases and a 20% price increase from first to final tier, every phase that passes means a higher entry price. The public listing price will be set ABOVE the final presale tier. Early participants get the best deal. Period.
Don’t be the person who understood the quantum threat but didn’t act. The presale has already raised over $500,000 from investors who understand what’s coming. The window for ground-floor positioning is closing.
