# 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).

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.expanse.tech/developer/what-are-the-test-networks.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
