//! NAC 马恩岛（Isle of Man） 辖区宪法规则验证插件
|
||
//! 监管机构：FSA（Isle of Man Financial Services Authority）
|
||
//! 关键法律：Designated Businesses (Registration and Oversight) Act 2015
|
||
//!
|
||
//! CBPP 四大原则：
|
||
//! - 约法即是治法：本插件条款即是IM辖区的链上治理规则
|
||
//! - 宪法即是规则：所有IM辖区交易的合法性由本插件判定
|
||
//! - 参与即是共识：节点加载本插件并参与出块，即代表对IM辖区宪法规则的背书
|
||
//! - 节点产生区块，交易决定区块大小：区块大小由实际交易量动态决定
