We used to have coinjoin transactions in practically every block. They were trending upwards, we were trending towards most of the block being coinjoin. Now it's rare to see even one small coinjoin transaction. This is SAD!

I wonder why
We need smooth implementation like sparrow + whirlpool → easy to set up so a non technical person could run it
True. It has to be as simple as Wasabi's implementation used to be, before they dropped out of the game: default coinjoin of any amount, without setup. If not, coinjoin will only be for the very few.
State is winning
don't worry, cashu will fix everything
If the timechain fees scale upwards to incentivize chain security as the block reward gets lower, then privacy solutions like coinjoining needs to scale in upward layers.
I wouldn't be as worried. It's definitely a shift, yes, and a time of transition where it's tougher to gain on-chain privacy, because there's little focus on on-chain privacy AND coinjoins aren't as active.
Split those up.
Stronger focus on privacy on the chain is paramount, but we can achieve what coinjoins achieve through upper layer protocols.
I have some hope in JoinMarket, a little more use right now, maybe we need time to migrate to others implementation, and of course LN could be a good option too in case you want to scramble/decouple some sats.
Does this include the "fake coinjoin" spends that sparrow/samourai does?
More wallets should be able to construct txns like that
