TC mixer is different though, it’s smart contract/zero proof based. Once it’s deployed, it just continues to work. Owners can’t steal funds. If you believe that smart contract is implemented correctly, you can continue to use it.

TC utility is diminished by other fact - TC is blocked on exchange level, exchanges do not accept funds coming from TC smart contract.

On a tangent, are smart contracts automatically “open source” - as in anyone can see the source or is there a way to obfuscate what’s on the blockchain?

I thought one of the selling points was that everybody can check the contract...

Just because contracts can exist whose code you don't have doesn't mean you don't know how anything works: not only can you build something on Ethereum that is open source and with verifiable behavior, that is currently the norm and obfuscated contracts are not taken seriously.

Just because you don't have the source code does not mean you cannot inspect what a binary does by disassembling it.

(And as any programmer will tell you, just because you have the source code available does not automatically mean you can see where it has a tricky edge case with massive security implications. The obfuscated C contests are proof of that)

You can obfuscate source code also--see what people do with JavaScript on websites--so the answer is "no" under any case. (In specific, though, contracts are implemented in a bytecode, so by more basic definitions of "open source" the answer is still "no".)

Smart contract’s binary code is visible to anyone once it’s deployed. (And it’s pretty simple to disassemble).

For most contracts they link actual source code to make inspection even easier - large part of trust in the system comes from the fact that contracts are inspectable.

An so just binaries which I guess means it’s not visible for all intents and purposes. Are there ready to go smart contract disassemblers?

example https://etherscan.io/bytecode-decompiler?a=0x610b8B78da143fC...

which uses https://github.com/palkeo/panoramix

All high profile smart contracts have reproducible and verified source code available on EtherScan.

Dissambly into Ethereum opcodes is doable, but do you find that readable?

But why allow your business to be traceable to a mixer which will put you in scope of criminal investigations? Racketeering is not legal.
