Course 02 · In depth
The cryptography, taught properly and without hand-waving.
What ML-DSA-65 actually is, why a signature weighs 3,309 bytes, what a hash does and does not protect, how hybrid encryption works, and — the part most courses skip — how to check every one of those claims yourself rather than believing this page.
For readers who want the mechanism, not the metaphor. Some mathematics is described; none is assumed.

- 01ML-DSA-65: the signature that holdsYou will be able to say what problem the scheme rests on, what the three key sizes are, and why that size is the price of the security rather than an inefficiency.8 min
- 02Hashes, addresses and what Grover really costs youYou will be able to explain what a hash guarantees, why an address is a hash of a key, and why hashing twice is not superstition.7 min
- 03Hybrid encryption, and where it is usedYou will be able to explain why encryption here combines a classical and a post-quantum algorithm instead of replacing one with the other.6 min
- 04Verifying it yourselfYou will be able to check a block, a release and an anchored file without trusting any page on this site.7 min
