**gexp (Go client)**

#### **DETAILS** <a href="#details" id="details"></a>

All parameters are the same as the main Expanse network except:

* Network Name: **Morden**
* Network Identity: 2
* genesis.json (given below);
* Initial Account Nonce (IAN) is 2^20 (instead of 0 in all previous networks).
  * All accounts in the state trie have nonce >= IAN.
  * Whenever an account is inserted into the state trie it is initialised with nonce = IAN.
* Genesis generic block hash: 0cd786a2425d16f152c658316c423e6ce1181e15c3295826d7c9904cba9ce303
* Genesis generic state root: f3f4696bbf3b3b07775128eb7a3763279a394e382130f27c21e70233e04946a9
