Just-In: Ethereum Developer Releases Key Warning Before The Merge

The Ethereum Merge is expected on September 15 as Ethereum clients and developers prepare for the merger of Mainnet (execution layer) with the Beacon Chain (consensus layer). Ethereum developer Marius Van Der Wijden on Tuesday warned that running multiple consensus layer nodes on one execution layer node such as Geth is unsafe and will cause execution issues.

Ethereum Developer Warns Community of Key Risks

Marius Van Der Wijden, an Ethereum developer working on Go Ethereum, in a tweet on August 30 said that running multiple consensus layer (CL) nodes on a single execution layer (EL) node is unsafe.

Users can run multiple validators on a single consensus layer node and execution layer node combination. However, running multiple consensus layer nodes on one execution layer will lead to errors. The combination might work for a while but will ultimately crash.

This is because different consensus layer nodes will share different state of details with execution layer nodes, resulting in execution conflicts. Therefore, it is critical to have a 1:1 relationship between the execution layer and consensus layer nodes.

“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 released updates for consensus layer and execution layer. The consensus layer clients are Lighthouse, Lodestar, Nimbus, Prysm, and Teku. Whereas, the execution layer clients are Besu, Erigon, Go Ethereum, and Nethermind.

The nodes must update both CL and EL clients for a successful implementation of the Merge. Before the Merge, the Bellatrix update will happen on the Beacon Chain at 11:34 am UTC on September 6 and the Paris upgrade will happen on the execution layer on September 15. Thus, leading to the merge of execution layer or Ethereum Mainnet with consensus layer or Beacon Chain.

Ethereum (ETH) Price Soars on Anticipation of the Merge

Although, the Ethereum (ETH) price will be deflationary after the Merge, the excitement within the community is rising. The positive sentiment is causing the ETH price to rise higher.

In the last 24 hours, the Ethereum price has soared nearly 10%, with the current price trading at $1,584. However, the price rally may be short-lived due to whales selling and over $2 billion in options expiry after the Merge on September 30.
