A lot of people assume the hardest part of post-quantum cryptography is the cryptography itself.
In our testing, that wasn’t really the case.
The bigger challenge came from the amount of additional data moving through the network once quantum-resistant signatures were introduced.
A single transaction signature increased from 65 bytes to ~2.4 KB.
That pushed:
• Transaction size from 110 B → ~2.5 KB
• Block size from ~110 KB → ~2 MB
• Native transfer TPS from 4,973 → 2,997
The result was higher cross-region propagation overhead and lower throughput ceilings, even though verification performance itself remained manageable.
