Recently, the group has been discussing data availability, ordering, finality, and so on.

Listening to a bunch of terms, but if you follow one line, it's simple:
Can your transaction be "tampered with" by others, and can you recover evidence if something goes wrong?
Ordering, in plain terms, is about who can jump the queue and whether they can be front-run;
Data availability is whether the on-chain ledger details are fully exposed, so you're not left with just "I guarantee it's fine";
Finality means don't think that seeing a successful confirmation means it's settled—restructure it, and you're back to square one.

By the way, I saw someone comparing RWA, US bond yields, and on-chain yield products...
My first reaction isn't whether the interest rate is high or low, but what exactly is this yield based on, who holds the contract permissions, whether it can be upgraded, and if emergency pauses can be activated with a single click.
Don't sign blindly, and don't relax just because you see the word "stable."
