What version of geth do i need for the merge? Will my node with Vectra (v1.10.20) run smoothly after the merge without updating to the latest version?

You will need at least Geth version 1.10.23 (Sentry Omega).


In addition to Geth (an execution layer client), you will also need to run a consensus layer client as in the announcement above, and then authenticate (connect) them as described below.

Install a consensus layer client


Assuming you are a Non-validating node operator, key action items include:

Authenticating the clients


Communication between the execution layer and consensus layer will occur using the Engine API. This is a new set of JSON RPC methods that can be used to communicate between the two client layers.

Instructions for how to set this JWT secret vary depending on the client — node operators should refer to their clients' documentation for instructions about how to generate and configure these.


here is a good writeup for the current situation: https://blog.ethereum.org/2022/08/24/mainnet-merge-announcement/
