Recently, everyone has been arguing about privacy coins and coin mixing—whether they count as "crossing the line."

I'm actually thinking about something more fundamental: on the blockchain, who is really deciding the "order of transactions" and the "final settlement"?
The terminology sounds intimidating, but it's actually just one main thread—first, someone has to be able to access the data (otherwise, you can't even verify), then how transactions are queued (queue jumping is very human), and finally, when is it truly settled and won't be reversed again.
To put it simply, you think you're playing with an asset, but you're actually betting on the trustworthiness of a process.
My perfectionism is kicking in again: I want to wait until the finality is clearer before taking action, but waiting and waiting, liquidity just runs away...
Anyway, I’ll keep an eye on the distribution of holdings and on-chain congestion, so I don’t wake up one day to find that "finality" is just psychological comfort.
