Genesis hash finder và fork Qtum

KhaiButDauXuan

Fork Qtum tạo chain mới Hãy xem video mình đã thực hiện, kết hợp với các câu lệnh đã được ghi lại bên dưới https://www.youtube.com/watch?v=5rqiGruTe4E

Như bitcoin đã biết nó mã hóa chuẩn SHA256, Litecoin là SCRYPT hay Dash là X11.. thì ta đã có các công cụ tìm genesis hash Dưới đây là một số công cụ để tìm genesis hash

https://github.com/vuicash/node-genesis-block

https://github.com/vuicash/GenesisH0

https://github.com/vuicash/generate-genesis

Nhưng một số coin nó không tiết lộ nên phải Debug Các bạn nên build từ bản cũ hơn của Qtum để tìm genesis hash cho nhanh Nó mất thời gian ở công đoạn chạy lệnh "make" mất tầm 30 phút Sau đó nâng cấp dần coin của bạn Qtum là một dự án khai thác trước Bạn sẽ tìm 5000 block đầu tiên rồi hãy tiến hành nâng cấp coin tạo checkpoint ở block thứ 5000 sau đó mới public Và tôi chọn Qtum làm vật thí nghiệm cho việc debug này

Cách Debug
