kovan.json 底部的節點列表是什麼？

Kovan的Genesis 文件在底部有一個節點列表。這些節點有什麼用？這只是已知 Kovan 節點的列表嗎？

根據spec.rs，nodes密鑰包含硬編碼的引導節點值：

/// Spec deserialization.
#[derive(Debug, PartialEq, Deserialize)]
#[serde(deny_unknown_fields)]
#[serde(rename_all = "camelCase")]
pub struct Spec {
   /// Spec name.
   pub name: String,
   /// Special fork name.
   pub data_dir: Option<String>,
   /// Engine.
   pub engine: Engine,
   /// Spec params.
   pub params: Params,
   /// Genesis header.
   pub genesis: Genesis,
   /// Genesis state.
   pub accounts: State,
   /// Boot nodes.
   pub nodes: Option<Vec<String>>,                     <------
   /// Hardcoded synchronization for the light client.
   pub hardcoded_sync: Option<HardcodedSync>,
}
