The Second-Slot Itch - Statistical Analysis of Reorgs

[randomishwalk]

@Nero_eth

Wrapping Up

The stats indicate a significant impact of certain slot indices within an epoch on the likelihood of being reorged. Furthermore, there are potential cascading effects of reorgs on consecutive slots. While individual reorg events are quite infrequent, their occurrence has notable effects on the following slot. For the CL clients, it appears there are some inefficiencies causing slots to be reorged.

The code for this analysis is available here .
A special thanks to Michael Sproul for open-sourcing the blockprint tool which helped identify reorgs and affected clients.

Question / update?

Any updated POV on this @Nero_eth given the recent spike in reorgs and the (related) polygon zkevm network outage?
