Ohio paused new tax credit deals for data centers this week. Governor Mike DeWine halted fresh commitments while the state reviews how much taxpayer money flows into hyperscale builds. The signal is small but worth watching. AI compute demand keeps climbing, and political tolerance for subsidizing it is starting to wobble.
Two pull requests against the geth repository closed in the same window today. One was a parallel state pruning experiment that ran into a database wall. The other was a defensive limit on a rarely used HTTP API that maintainers decided was not worth the maintenance load. Together they show how Ethereum execution client decisions actually get made: benchmarks, not narratives.
A new Ethereum core change is moving through go ethereum, the most widely deployed client. It raises the gas cost for opcodes and operations that grow chain state, and it tightens how the network refunds gas when authorization slots clear. The pull request crossed another milestone on May 22, 2026 with regenerated tracing code, which usually signals that the implementation is converging on a final shape.
Alphabet trades like an ad company but operates like a holding firm. Inside the GOOGL share sit a minority piece of SpaceX, a majority piece of Waymo, and a growing AI infrastructure tab. Today’s notes tie those threads together with a side trip into Ethereum protocol plumbing.
Ethereum’s main execution client just landed a small but practical change. Code cache hit and miss meters now ship as first class Prometheus signals, so operators no longer have to dig through slow block JSON dumps. The kind of unglamorous engineering that compounds across the network.
