我想在内网中搭建一条比特股测试网络，计划搭建3个见证节点，并实现通过WEB钱包进行账号注册和交易。我修改了对应/libraries/chain/include/graphene/chain/config.hpp。
#define GRAPHENE_SYMBOL "CORE"
#define GRAPHENE_ADDRESS_PREFIX "GPH"
编译运行witness_node，当然对应genesis.json也进行修改。
然后在bitshares-UI编译并运行。通过web访问，当创建钱包是提示错误：Failed to create account: jia-yin - 10 assert_exception: Assert Exception base58str.substr( 0, prefix_len ) == prefix: {"base58str":"GPH6zD5zHn2hP91tGmPaWmzofR86hWAt9nEEyyYUJt4nnocBTg8Fv"} th_a types.cpp:60 public_key_type。

请大牛帮我看看，到底问题出在哪儿？

I would like to build a test network, in the virtual machine to build a witness node, and then in the host through the web access node, create a new account error.
Failed to create account: jia-yin - 10 assert_exception: Assert Exception base58str.substr (0, prefix_len) == prefix: {"base58str": "GPH6zD5zHn2hP91tGmPaWmzofR86hWAt9nEEyyYUJt4nnocBTg8Fv"} th_a types.cpp: 60 public_key_type.

Please help me to see, in the end what is the cause?
