Recently, a bunch of new L1/L2 projects have started incentivizing to pull TVL, and I totally understand the complaints from old users about "mining, selling, and dumping"... To put it simply, don’t be scared by terms like "data availability / ordering / finality." I’ll focus on one main thread: where does this chain/layer actually put the "truth of the ledger," who writes it first, and how long before it’s considered solid? Data availability is whether you can get the complete evidence; ordering is who can cut in line and change the sequence; finality is whether you can still reverse things after a rollback. When incentives kick in, the easiest thing to go wrong isn’t usually poor technology, but rules that give people room to exploit loopholes.
