Merge has successfully cut across two out of the three public testnets. As we know that the Ethereum was expected early this month, Tim Beiko, Network developer, disclosed the Bellatrix upgrade which was slated for June 2nd. This upgrade was done to open the door for the first public testnet, the Ropsten Beacon Chain in preparation for the Merge.
Recall, on May 30th, Ethereum announced the release of a new beacon chain on the Ropsten network to provide consensus, the proof-of-work that permits the nodes of the Ethereum network to agree on the state of all information recorded on the Ethereum blockchain and secures particular kinds of economic attacks.
Remember, after years of work to integrate proof-of-stake on Ethereum, the team is gradationally hitting the end of the tunnel in making it a reality, as the Sepola public testnet is being done successfully. It is good to know that the Merge is run on the public testnet to check if the validator nodes from both the execution layer, proof-of-work and Beacon chains, and proof-of-stake of these testnets are compatible. Getting them as planned is a pointer to sure of mainnet activation.
Knowing from the above statement, at the Merge, Sepolia’s execution layer represents the proof-of-stake merged with its beacon chain consensus layer as proof-of-stake. With this, the node operators on Sepolia’s consensus and execution layers update their client software as followed.

Goerli/prater, the last public testnet
Once Georli/prater upgrade is successful, there will be nothing hindering the merge on the mainnet. Georli is simply an execution layer testnet while prater is a consensus layer testnet.
Community asks the question regard to what will happen if there is 25-30%, another person dropped a thought that the network would maintain metastability and nodes that will remain offline will pay the penalty.
