Fatal: Failed to register the Ethereum service: only PoS networks are supported, please transition old ones with Geth v1.13.x

Question

Trying to create a Private Ethereum Network Locally. I am getting following error when trying to start the Node(genesis node)

Will update the solution by installing older version!

Answer 1

I know this question is a bit older, but since I had the same issue and found a solution, I am going to give it hear in case someone else stumbles upon it.

As you, I am setting up a private blockchain using Geth v1.14.13.

Like you, I got:

Failed to register the Ethereum service: only PoS networks are supported, please transition old ones with Geth v1.13.x 

I assume you are using a custom genesis.json file. You would need to add "terminalTotalDifficulty":0 and "terminalTotalDifficultyPassed":true to your genesis file:

Here a genesis.json file which I obtained using geth --dev dumpgenesis:

    "baseFeePerGas":"0x3b9aca00",
    "excessBlobGas":null,
    "blobGasUsed":null
}

I did that so that I could change the chain id.

To use it, run:

geth init /root/genesis.json

geth --datadir /root/.ethereum \
  --dev \
  --http --http.api eth,net,web3,personal --http.addr 0.0.0.0 \
  --allow-insecure-unlock \
  --dev.period 2

That will start your Geth node in dev mode and seal new blocks every 2 seconds - no need for a consensus client.

Enjoy :)
