Core Viewpoint - The article emphasizes the historical experience of medieval England in maintaining currency stability through institutional reforms, which provides valuable insights for modern digital currency governance [1][2]. Group 1: Currency Stability in Medieval England - Unlike other European countries that frequently debased their currencies to increase fiscal revenue, the English government adopted a more prudent approach, maintaining currency unity and value stability by not reducing coinage quality [4][6]. - The core of this policy was to uphold currency credit and ensure market trust in currency value, reflecting the government's long-term vision in fiscal management [4][6]. - Centralized minting, the introduction of a pricing system for mints, and periodic devaluation were key strategies that helped maintain currency stability, making English currency one of the most stable in Europe [4][6]. Group 2: Government's Role in Currency Management - The stability of medieval England's currency was a rational choice by the government, balancing short-term interests with long-term credit, avoiding inflation and market trust crises caused by currency devaluation [6]. - Legislative measures were implemented to protect currency from counterfeiting, clipping, and the influx of foreign coins, establishing a stringent currency credit system [6]. - The 1279 Currency Act set clear standards for coin weight and quality, with severe penalties for violations, demonstrating the importance of legal frameworks in ensuring stable currency circulation [6].
