Description

Website
Github PoC releases (currently: PoC 4)
Doc for PoC-0 - contains usage example.

What the PoC supposedly already can do:

bidirectional channels
P2P routed channels (no direct connection necessary)

There's a time difference of min. 10 blocks between channel closing and settling for security reasons.

Subject changed from Research Raiden (state channel) to Research Raiden (state channels)
Description updated (diff)

contract addresses for Ropsten: https://pypi.python.org/pypi/raiden/0.0.4

Install from source worked, but when running it, scrypt couldn't be loaded:

Failed to import scrypt. This is not a fatal error but does
mean that you cannot create or decrypt privkey jsons that use
scrypt

Since the next step is trying to unlock an account, that makes it a non-starter.

2nd try:

virtualenv venv
source venv/bin/activate
pip install --upgrade setuptools
pip install rlp==0.4.6
pip install raiden

worked. However:

venv/bin/raiden --eth_rpc_endpoint 127.0.0.1:2017 --address 0x50258d38ae3c13a6709522edc1e45105521f0e39 --keystore-path /home/didi/src/die-unendliche-wahl/blockchain/testnet-admin/keystore/ --discovery_contract_address 0x79ab17cc105e820368e695dfa547604651d02cbb --registry_contract_address 0x32c5dab9b099a5b6c0e626c1862c07b30f58d76a

~~
No idea what this complaint is about, giving up here.~~

The contract addresses need to be delivered without leading 0x:
venv/bin/raiden --eth_rpc_endpoint http://127.0.0.1:2017 --address 0x50258d38ae3c13a6709522edc1e45105521f0e39 --keystore-path /home/didi/src/die-unendliche-wahl/blockchain/testnet-admin/keystore/ --registry_contract_address 32c5dab9b099a5b6c0e626c1862c07b30f58d76a
New command, new error:
