Pectra Testnet Update 📣

On Monday, Pectra activated on Holesky. An EL bug caused chain splits, resulting in a minority chain being valid, degrading the network health.

Holesky validators must take action ASAP, some Sepolia users must upgrade their client.

Holesky validators: we are coordinating a mass slashing event tomorrow Feb. 28 around 15:00 UTC. 

You should: 
   1. Update your node (see screenshot)
   2. Sync your node to head (new CL branches will help)
   3. Right before slot 3737760, disable slashing protection

Sepolia node operators: the fork will happen as previously scheduled at epoch 222464 (Mar. 5, 7:29 UTC). 

If you are using Geth, Besu, Nethermind or Lodestar, you must update your client to one of the releases listed here: https://blog.ethereum.org/2025/02/14/pectra-testnet-announcement
