Let’s talk about data availability.
If a block producer publishes only the block header while withholding some transaction data, no one else can check whether the results are correct.
Honestly, I only learned this later: when comparing Layer 2 solutions, check where transaction data is published: Ethereum, an independent data availability network, or an off-chain committee. Each has different security assumptions.

It’s best to invest only what you can afford to lose.
