74% of Ethereum nodes ‘ready to integrate’ before Bellatrix upgrade

Up to 73.5% of Ethereum nodes are now rated “ready for consolidation” ahead of Bellatrix’s upcoming upgrade to Ethereum on September 6, according to data from Ethernodes.

The Bellatrix upgrade is seen as one of the last necessary steps before a formal merger, which will see Ethereum transition to a proof-of-stake consensus mechanism between September 10-20.

To become ready for integration, Ethereum node operators must comply with the Bellatrix upgrade by updating pre-era consensus layer 144896 clients on the Beacon chain, which is scheduled to take place at 11:34:47 AM UTC on September 6, 2022, according to the Ethereum Foundation.

However, with as many as 26.7% of nodes rated as “not ready” for Ethereum Merge, Ethereum co-founder Vitalik Buterin and core developer Tim Beiko have taken themselves to Twitter to push the remaining node operators to update their customers.

According to the Ethereum Foundation, node operators that do not perform the update prior to the Bellatrix upgrade will cause Ethereum clients to “sync with the pre-fork blockchain,” a warning:

“[Node operators] You will be stuck in a non-compliant chain according to the old rules and will not be able to send Ether or work on a post-Ethereum network.”

According to the Ethernodes network, most of the “not ready” nodes were found on the geth client, which has not yet upgraded to Geth v1.10.23 or later.

Other Ethereum clients that need to be updated are Erigon, Besu, and Nethermind.

Ethereum nodes are required to validate the blocks and can be run by different Ethereum client software that varies in the programming language used and the code base.

After the Bellatrix upgrade, the final part of the Ethereum consolidation will take place in the so-called “Paris Event,” which will be triggered when the Final Final Difficulty (TTD) reaches 58750 trillion trillion, which is estimated to occur around September 15.

Once this execution layer bypasses the TTD, the next block will be generated by the Beacon Chain validator. The completion of this block will mark the complete transition of the Ethereum blockchain to a Proof of Stake mechanism.

According to the Ethereum Foundation, Ethereum users do not need to do anything with their ETH and Ethereum-based assets during the merger but should be on the lookout for scams that suggest otherwise.
