# What are the test Networks?
### **MORDEN TESTNET**
Morden is a public Expanse alternative testnet. It is expected to continue throughout the Frontier and Homestead milestones of the software.
#### **USAGE**
**exp (C++ client)**
This is supported natively on 0.9.93 and above. Pass the –morden argument in when starting any of the clients. e.g.:
**PyEthApp (Python client)**
PyEthApp supports the morden network from v1.0.5 onwards:
**gexp (Go client)**
#### **DETAILS**
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
**Morden’s genesis.json**
#### **GETTING MORDEN TESTNET EXPANSE**
Two ways to obtain Morden testnet expanse:
* Mine using your CPU/GPU, (see [Mining](http://docs.expanse.tech/en/latest/mining.html#mining)).
* Use the [Expanse wei faucet](https://zerogox.com/expanse/wei_faucet).
