//! NAC 毛里求斯(Mauritius) 辖区宪法规则验证插件
|
||
//! 监管机构:FSC(Financial Services Commission Mauritius)
|
||
//! 关键法律:Virtual Asset and Initial Token Offering Services Act 2021(VAITOS)
|
||
//!
|
||
//! CBPP 四大原则:
|
||
//! - 约法即是治法:本插件条款即是MU辖区的链上治理规则
|
||
//! - 宪法即是规则:所有MU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MU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
