DarkFi is a very interesting project, with DarkFi we can transfer Bitcoin anonymously, it is a tornado cash by default.

Strong points:

- Decentralized

- Anonymous (ZK proofs)

Weak points:

- It's a blockchain, it's not scalable.

- The other receiver has to be on DarkFi as well.

At the end of the day, you have to have a set of tools that allow you to use your bitcoin anonymously, the darkness is looming faster than privacy develops in Bitcoin.
