The same public idea, a different chain, and no connection between the projects.
Plainly: SolanaMixer.fun is not affiliated with Tornado Cash, shares no code or people with it, and carries none of its history. The underlying idea — a fixed-denomination pool with zero-knowledge withdrawals — is public and has been built independently many times. That is what is shared, and it is the only thing.
Fixed denominations so deposits are interchangeable. A commitment written into a Merkle tree. A proof of membership instead of a receipt. A nullifier recorded so a note cannot be spent twice. A relayer so a new wallet need not be funded first. Any honest implementation looks like this, because that is the design.
| Ethereum pools | Here | |
|---|---|---|
| settlement | minutes, variable | seconds |
| cost per note | gas-dependent; historically dollars to tens of dollars | ~0.001 SOL, flat |
| verification | EVM precompiles | BN254 syscall, ~110k compute units |
| biggest cost | gas at the moment you transact | permanent nullifier rent, paid once |
The flat low cost is what actually differs day to day. On Ethereum, mixing a small amount could cost more than the amount. Here the fee is the same whichever pool you use, so choosing a pool is a privacy decision rather than a budget one.
The pool, the anonymity set, the reputation and the legal history. These pools started empty and are as deep as they are today — a number printed on the picker, not inherited from anyone else. Any service implying it starts with someone else's crowd is misleading you.
