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

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

Cách Debug
