gen_protocolVersion

Reserved for reporting the GenLayer protocol version. Not implemented — the method is registered and reachable, but every call returns an error.

Method: gen_protocolVersion

Parameters: None currently read — any params supplied are ignored because the method returns before parsing them

Returns: Nothing. The call always fails with JSON-RPC error code -32004

Example Request:

{
  "jsonrpc": "2.0",
  "method": "gen_protocolVersion",
  "params": [],
  "id": 1
}

Example Response:

{
  "jsonrpc": "2.0",
  "error": {
    "code": -32004,
    "message": "method not implemented: gen_protocolVersion"
  },
  "id": 1
}

Notes:

• The method is registered in the genlayer endpoint group, so it is reachable and rate-limited like any other method — it just cannot succeed
• The error code is -32004 ("method not supported"), not -32601 ("method not found"): the node recognises the method and is declining to serve it, rather than failing to route it
• To identify what a node is running, use the ops server's GET /health, which reports node version and sync state
• eth_protocolVersion is unaffected — it is proxied to the GenLayer chain like any other eth_* method
