func updateSafrole (Safrole)

處理與 Safrole 協議相關的狀態更新。Safrole 負責驗證者的選擇、輪換和 Ticket 管理

目的是根據最新的 slot、entropy、offenders 以及 extrinsics 中提交的 tickets 來更新 Safrole 狀態。最終返回更新後的 SafrolePostState，並根據不同條件可能附帶返回 epochMark 以及 ticketsMark

架構

1. 初始化與驗證： 讀取配置、計算當前與新 epoch/phase，並驗證 slot 以及 extrinsics 的合法性。

2. VRF：

加密貨幣期貨現貨套利策略簡報

策略簡介

• 策略名稱： 加密貨幣期貨現貨套利（Funding Rate 套利）
• 策略目標：
  透過對沖現貨與期貨倉位，在永續期貨資金費率機制下捕捉收益。
• 基本概念：
  • 當 funding rate 為正：多頭支付費用，空頭獲得收益 → 策略：做空期貨、持有現貨
  • 當 funding rate 為負：反之則操作 → 策略：做多期貨、空現貨
