Goal: <33% | Danger: >50%
Many know client diversity is important for a more resilient network, but they don't understand why or just how essential it is. It's not only important — it's critical. If a single client is used by 2/3rds (66%) of validators, there's a very real risk this can result in disrupting the chain and monetary loss [1, 2] for node operators.
It takes 2/3rds of validators to reach finality. If a client with 66%+ of marketshare has a bug and forks to its own chain, it'll be capable of finalizing. Once the fork finalizes, the validators cannot return to the real chain without being slashed. If 66% of the chain gets slashed simultaneously, the penalty is the whole 32 ETH.
So why is >50% marketshare still dangerous? If a minority client forks, the 50%+ majority client can obtain a 66%+ majority. With no client having a marketshare over 33%, these scenarios are avoided. That's why <33% marketshare is the goal for all clients.
Execution clients are not immune. The risks mentioned above apply to both consensus clients and execution clients equally.

For a guide on how to switch clients using LUKSO tools,
see LUKSO docs guides
Guides for switching clients manually are listed below.
Error: Select both To and From clients.
There are no guides for this migration yet.
The above guides will help to switch the clients.
Please note that to run the clients for LUKSO, you need to start them with the correct config.yaml and genesis.json files.
To see how, also read the become a validator and the switch clients documentation.
