According to data from Ethernodes, 73.5% of Ethereum nodes have been marked “Merge Ready” in advance of the Bellatrix upgrade for Ethereum that will take place on Sept. 6.
The Bellatrix upgrade will be one of the final steps before the official Merge. This will see Ethereum move to a proof–of-stake consensus mechanism, between Sept. 10-20.
The Ethereum Foundation states that to be Merge Ready, Ethereum node operators must comply to the Bellatrix upgrade and update their consensus layer clients before epoch 144896, which is scheduled for Sept. 6, 2022 at 11:34:47 UTC.

With 26.7% of nodes “Not Ready” for Ethereum Merge, Vitalik Buterin, Ethereum cofounder, and core developer Tim Beiko took to Twitter to share updates from the remaining node operators to their clients.
Bellatrix tomorrow! Last chance to upgrade your node, if not yet! We’re mergiiiing https://t.co/0VQ9zb6wjN

The Ethereum Foundation warns that node operators who fail to update their clients prior to the Bellatrix upgrade, will cause them to “sync with the pre-fork Blockchain.”
“[Node operators] will remain stuck on an incompatible network following old rules, and will not be able to send Ether or work on the post-Merge Ethereum Network.”
Ethernodes claims that most of the “Not Ready” nodes can be found on the geth client. They have not yet upgraded to Geth v1.10.23 and higher.
Besu and Erigon are other Ethereum clients that need to be updated.
Ethereum nodes are needed to validate blocks. They can be run using different Ethereum client software, which varies in the programming language and code base.

Following the Bellatrix upgrade, the last part of the Ethereum Merge will occur in what is called the “Paris event,” which will be triggered when the Terminal Total Difficulty (TTD) reaches 58750000000000000000000, which is estimated to occur around Sept 15.

A Beacon Chain validator will produce the next block once the execution layer has exceeded this TTD. This block marks the transition from Ethereum’s blockchain into the proof-of stake mechanism.
The Ethereum Foundation states that Ethereum users don’t need to do anything during the Merge with their ETH or Ethereum-based assets, but they should be aware of scams.
