Validator Registrations on Goerli/Prater
Much appreciation to jcrtp#0477 from Rocketpool and Yorick from EthStaker for flagging issues registering validators with various client configurations on the Goerli network. According to the builder-spec, only pending or active validators should be sent to MEV-Boost for validator registration, and not exited validators. Github issues to implement this designation have been filed with Nimbus, Teku, and Lighthouse. Prysm does not appear to be affected by this problem. We are grateful for your testing support, and will continue to monitor progress. Please refer to 502 During Validator Registration with an Exited Validator #245 for further updates and contributions.
