Morden

Morden is the first Ethereum alternative testnet. It is expected to continue throughout the Frontier and Homestead era.

Usage

TurboEthereum (C++)

This is supported natively on 0.9.93 and above. Pass the --morden argument in when starting any of the clients. e.g.:

> eth --morden

Or, for AlethZero

> alethzero --morden

PyEthApp (Python client)

PyEthApp supports the morden network from v1.0.5 onwards:

> pyethapp --profile testnet run

geth (Go client)

> geth --testnet

Parity

> parity --chain=morden

Details

• Network Identity: 2
• All parameters same as Frontier except:
  • 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 block hash: 0cd786a2425d16f152c658316c423e6ce1181e15c3295826d7c9904cba9ce303
• Genesis state root: f3f4696bbf3b3b07775128eb7a3763279a394e382130f27c21e70233e04946a9
