NAC 一键上链系统 - 17步上链流程核心路由
|
||||||
|
完整流程:
|
||||||
|
阶段一（确权与权证）:
|
||||||
|
1. 资产申请上链 (assets.py)
|
||||||
|
2. 进入资产合规流程
|
||||||
|
3. 资产审批流程
|
||||||
|
4. 资产估值流程
|
||||||
|
5. 产生加密DNA
|
||||||
|
6. 获得链上确权
|
||||||
|
7. 产生TOKEN（权证数据结构）
|
||||||
|
8. 产生CODE
|
||||||
|
9. 发放链上权证凭证
|
||||||
|
阶段二（权益衍生与托管）:
|
||||||
|
10. 衍生权益化资产
|
||||||
|
11. 上链托管TOKEN所有权
|
||||||
|
12. 资产交第三方托管
|
||||||
|
13. 铸造XTZH
|
||||||
|
阶段三（发行与流通）:
|
||||||
|
14. 发行权益化资产代币
|
||||||
|
15. 区块链浏览器显示
|
||||||
|
16. 装入钱包
|
||||||
|
17. 交易所上线
