In order to test:

• create a file called genesis_beverlyhills.json with the following content:

{
  "config": {
    "chainId": 90210,
    "homesteadBlock": 0,
    "daoForkBlock": 0,
    "daoForkSupport": false,
    "eip150Block": 0,
    "eip150Hash": "0x2086799aeebeae135c246c65021c82b4e15a2c451340993aacfd2751886514f0",
    "eip155Block": 0,

    "muirGlacierBlock": 0,
    "berlinBlock": 0,
    "londonBlock": 0,
    "cancunBlock": 0,
    "ethash": {}
  },
  "nonce": "0x56",
  "timestamp": "0x0",
  "extraData": "0x",
  "gasLimit": "0x2fefd8",
  "difficulty": "0x1",
  "mixHash": "0x0000000000000000000000000000000000000000000000000000000000000000",
  "coinbase": "0x0000000000000000000000000000000000000000",
  "alloc": {

      "balance": "0x400000000000000000000"
    }
  },
  "number": "0x0",
  "gasUsed": "0x0",
  "parentHash": "0x0000000000000000000000000000000000000000000000000000000000000000",
  "baseFeePerGas": null
}

• Build geth and Initialize its directory at $DATADIR with go build ./cmd/geth/... && ./geth --datadir=$DATADIR init genesis_beverlyhills.json
• Run geth: ./geth --datadir=$HOME/.beverlyhills --networkid=90210 --http --http.api "net,eth,debug,engine" --allow-insecure-unlock --vmodule=rpc=5 --syncmode=full

Upon creating blocks and calling engine_getPayloadV1, it should return a block with the aforementioned verkle proof fields.
