IBOX system development core functions and some core source codes

The core functions of the IBOX system are as follows:
　　1. On-chain of collections.
　　Digital collections can be easily on-chain and released quickly with one click; 　　2.
　　Distribution of collections
　　With powerful promotion and distribution functions, users become promoters ; A set of systems can be generated freely; 　　4. Gift on the chain Support the collection gift function and improve the user experience; 5. Open interface Can access the original APP, small programs, etc.

The following is the core source code of the collection unit synthesis in the iobx system
