most "privacy blockchain" claims boil down to the same one tool: zero-knowledge proofs. prove a transaction is valid without showing what's inside it.
dusk network's hedger module — the thing powering confidential trading on duskevm — doesn't stop there. the reason why is more interesting than the privacy pitch itself.
per dusk's own "Learn About Hedger" writeup: zk proofs are great at proving a computation happened correctly. they're not built for actually computing ON encrypted values. if you want to match two encrypted orders in a private order book, or update an encrypted balance without a moment of exposure, pure zk struggles with that specifically.
so hedger adds homomorphic encryption underneath it — elgamal over elliptic curves. HE lets you do real arithmetic directly on ciphertext. add two encrypted numbers, get an encrypted sum, never decrypt either input. that's a genuinely different capability than "prove this was correct after the fact."
combined, that's what lets dusk build toward obfuscated order books — institutional trading where order size and price stay encrypted the entire time, not just during settlement.
here's the part i can't resolve: homomorphic encryption is famously expensive to compute. it's the main reason most privacy systems skip it and lean on zk alone. dusk is betting that layering HE under a full EVM-compatible chain doesn't choke throughput once real trading volume shows up, not just testnet transactions.
that's an unproven bet, not a solved one yet.
