Before the Merge, an Ethereum developer issues a critical warning

The Ethereum Merge is set to take place on September 15th, as Ethereum clients and developers prepare for the merger of Mainnet (execution layer) and Beacon Chain. On Tuesday, Ethereum engineer Marius Van Der Wijden warned that running several consensus layer nodes on a single execution layer node, such as Geth, is risky and will result in execution difficulties.

A key risk has been identified by an Ethereum developer.

In a tweet on August 30, Marius Van Der Wijden, an Ethereum engineer working on Go Ethereum, stated that operating several consensus layer (CL) nodes on a single execution layer (EL) node is risky.

Multiple validators can be run on a single consensus layer node and execution layer node combination. Running numerous consensus layer nodes on the same execution layer, on the other hand, will result in failures. The combo may work for a while but will eventually fail.

Because distinct consensus layer nodes will share varying state of details with execution layer nodes, execution conflicts will occur. As a result, a 1:1 link between the execution layer and consensus layer nodes is critical.

“The CL sets the head of the EL. If you have two nodes telling it their (differing) world views, it will flip flop and re-execute a lot of blocks while doing so. You can see what happens in the picture, the node switches between the head and head -2k.”

The Ethereum clients have updated the consensus layer and the execution layer. Lighthouse, Lodestar, Nimbus, Prysm, and Teku are the consensus layer clients. Besu, Erigon, Go Ethereum, and Nethermind are the execution layer clients.

To successfully implement the Merge, the nodes must update both CL and EL clients. Before the Merge, the Bellatrix update will take place on the Beacon Chain on September 6 at 11:34 a.m. UTC, and the Paris upgrade will take place on the execution layer on September 15. As a result, the execution layer or Ethereum Mainnet will be merged with the consensus layer or Beacon Chain.

The price of Ethereum (ETH) has risen in anticipation of the merger.

Although the Ethereum (ETH) price will be deflationary following the Merge, the community’s excitement is growing. The optimistic feeling is driving up the price of ETH.

The Ethereum price has risen about 10% in the previous 24 hours, with the current price trading at $1,584. The price gain, however, may be short-lived due to whales selling and more than $2 billion in options expiring after the Merge on September 30.
