ZeroLink VS joinmarket-clientserver

So far, the only viable/strong tumbling option out there for non experts is: https://github.com/nopara73/ZeroLink

All of this despite the current Tor DDoS attack which is still not yet solved, and this affects Wasabi a lot because it relies heavily on Tor, specially with the new coinjoin protocol WabiSabi that works differently than the old protocol ZeroLink, because it needs to register each input with a new Tor identity.

Zerolink is a CoinJoin-type protocol where there is a central server that coordinates the CoinJoin mixing transactions between participants who never interact between themselves, thus can’t de-anonymize themselves. The central server never receives the coins, he only batches the inputs to create the big transaction, so he can’t steal coins as a Centralized Tumbler mixer would. It also communicates with blind signatures for their output addresses, which basically allows them to preserve anonymity from the central server as well. This protocol has been developed by Adam Fiscor, Lead developer of the Wasabi Wallet.

Whirlpool is a flawed implementation of the ZeroLink privacy framework I created back in 2017.

It's complicated. The more steps you take to obfuscate your transaction, the harder it will be for an adversary to track your coins. You can look into using something like the JoinMarket Wallet to keep your transaction more private.

You can use coinjoin services like joinmarket to anonymize your coins. You can also send them through a lightning swap.

This is a bitcoin service delivered in a low trust manner where the bitcoin user need only utilize software they run and control for the services and can protect themselves from malicious third parties with very little trust or consequence from peers. This is the gold standard of Bitcoin service. Examples include lightning routing, lightning liquidity marketplaces like pool, coinjoins like joinmarket, coinswaps, submarine swaps like loop and others.

If you want to play with OP_CHECKLOCKTIMEVERIFY, you can use the wallet in JoinMarket to create a fidelity bond. Be careful, though, because it's absolutely impossible to spend such a bond until its expiration.

I opened a GitHub issue - https://github.com/JoinMarket-Org/joinmarket-clientserver/issues/1349.
