Privacy Coins vs Mixers vs CoinJoin: What's Actually Different
Three different answers to 'hide this transaction'. Only one is native to the protocol itself.
Three approaches dominate the conversation: mixers (Tornado-style smart contracts), CoinJoin (collaborative multi-user transactions, e.g. Whirlpool on BTC), and privacy coins (Monero, Zcash shielded pools). They differ technically and, increasingly, legally.
Mixers work by pooling deposits from many users into one contract and letting each withdrawal from a different address. The problem: the set of deposit/withdrawal pairs is on-chain and public. Statistical analysis over time — plus timing heuristics — has successfully de-anonymized users of even the largest mixer. And the mixers themselves keep getting sanctioned, so where the cash sat matters too.
CoinJoin improves on that by collapsing inputs/outputs into a single collaborative transaction, but the transaction is still visible — you're relying on many participants to stay online, and analytics firms specifically fingerprint CoinJoin patterns.
Privacy coins bake the privacy into the protocol itself. Monero's ring signatures, stealth addresses, and RingCT make every transaction private by default — there's no suspicious 'mixing step' to flag. On its chain, a private transaction is not the anomaly; it's the universal case, and that removes the heuristic attack surface entirely. (how Monero privacy works)
Where we stand: VeilSwap routes swaps into Monero and Zcash but doesn't operate a mixer — we don't pool other people's deposits into shared contracts, we don't obscure our own payout flows, and every order's deposit address is distinct. The privacy we offer is the coin's native privacy, plus non-custodial order plumbing — nothing more ambitious, and nothing pretending.
