In Layer 2

Optimism released two operator updates for the OP Stack: op-supernode v1.0.3 and op-node v1.19.8. The releases tighten hardfork validation, and Sepolia OP Stack operators are told to be on op-node v1.19.5 or later before the Oct. 6 Glamsterdam hardfork.

What this rests on

Claim by claim, with its source
✓
Optimism released op-supernode v1.0.3 as an optional operator update that tightens validation around hardfork activation times and rejects invalid post-genesis fork ordering in custom rollup configs.
✓
The release notes say existing chains in the Superchain registry are not affected by the configuration issue described in the update.
✓
Sepolia OP Stack operators need op-node v1.19.5 or later before the Oct. 6 Glamsterdam hardfork.

The move was larger before the first headline than after. That is an observation, not an explanation: the market also moves on things nobody publishes.

How the story was built

Every piece in order, with the time its news medium declares — if it is not believable we use ours and say so — and what it added to what was already known at that point. Arriving first is not the same as adding something.
