Recently, there has been talk again about sharding and parallel processing.

To be honest, it's just lively chatter; in the end, it's still the same two issues:
Where to place assets for maximum safety, and how to exit when you really want to leave.
No matter how high the performance, if there's a hole in the bridge, cross-chain, or shared security circle, it could all blow up in one go.
Don’t tell me “it’s theoretically safe.”
Now I look at projects first by asking about exit strategies:
Where is the liquidity, are there any redemption gates, and in extreme market conditions, who gets sacrificed first?

Some people compare RWA (Real-World Assets) with US Treasury yields and on-chain yield products...
They’re quite good at storytelling, but the sources of returns, custody, and liquidation logic are far apart.
Don’t automatically assume “stable returns” mean low risk just because of the phrase.
Anyway, I’m used to taking screenshots first, then reviewing and cross-referencing later—it's pretty handy.
