The format of fields when writing or reading the status is determined by the string field State storage format, which is set when creating a smart contract. It should contain a string of JSON type with description of “key:type”fields. The following designations are allowed as a type:

    {} - object

    [] - array

    uint - 6-byte unsigned integer

    uint32 - unsigned integer 4 bytes long

    uint16 - unsigned integer 2 bytes long

    byte - unsigned integer 1 bytes long

    double - double precision number (8 bytes long)

    str - the variable-length string

    strxx - string with fixed length of xx long

    arrxx - byte array with fixed-length of xx long

    Example:

    {Name:str10, Value:uint, PubKey:arr33}

    {Type:byte,Account:uint,SumCOIN:uint,SumCENT:uint32, arr:[uint]}
