Raiden on Private Network Tutorial

Introduction

This tutorial shows how to run Raiden on a private network, using the master branch (this is useful when you are working on a pull-request). This tutorial assumes Ubuntu 18.04.2 LTS and bash.

Creating a Virtual Environment

In a shell, run

$ sudo apt-get install libncurses5-dev
$ mkdir priv_chain

If mkdir fails, choose a different name, or move the existing priv_chain directory to somewhere else.

$ cd priv_chain
$ virtualenv -p python3.7 env
$ source env/bin/activate

You should now be in the virtual environment, where all Python package installations are separately managed.

Now the command prompt should look like:

(env) $

Install Raiden and dependencies

(env) $ pwd
<snip>/priv_chain
(env) $ git clone https://github.com/raiden-network/raiden
(env) $ cd raiden
(env) $ make install-dev

Launch a private network

Installing Geth

Follow the guide and install Geth. A command geth should be available in your shell. This guide assumes version 1.8.26, but other versions might work.

Preparing a genesis config

Prepare a file genesis.json with the following content (@offerm kindly allowed to use his file here).

(env) $ cd ..
(env) $ pwd
<snip>/priv_chain
(env) $ cat genesis.json
{
"config": {
"chainId": 4321,
"homesteadBlock": 0,
"eip150Block": 0,
"eip155Block": 0,
"eip158Block": 0,
"ByzantiumBlock": 0
},
"alloc": {},
"difficulty" : "0x1",
"gasLimit"   : "0x9880000"
}

Starting a chain

With the genesis.json you can initialize a blockchain.

(env) $ pwd
<snip>/priv_chain
(env) $ geth --datadir blkchain1 init genesis.json
(env) $ geth --rpc --datadir blkchain1 --networkid 4321 --rpcapi "eth,net,web3,txpool" console
<snip>
> personal.newAccount()
"0xd4de892c06cf4a0557c7d515f79fd20b8356d6cf"

Copy the shown address somewhere. And start mining on your own private blockchain.

> miner.start()

In this console geth should keep running.

Figure out the contract version

Open a new console, and load the Python environment.

$ pwd
<snip>/priv_chain
$ source env/bin/activate
(env) $

In the raiden directory, figure out the value DEVELOPMENT_CONTRACT_VERSION

(env) $ cd raiden
(env) $ grep 'DEVELOPMENT_CONTRACT_VERSION = ' -r .
./raiden/settings.py:DEVELOPMENT_CONTRACT_VERSION = '0.10.1'

Copy the shown version somewhere.

Define constants

The contract version will be used quite often, so let bash remember it.

(env) $ export VERSION="0.10.1"

You will need your private key for the account you created.

(env) $ cd ..
(env) $ pwd
<snip>/priv_chain
(env) $ export PRIV_KEY=./blkchain1/keystore/UTC-<use TAB-completion to fill in>

If the TAB-completion shows more than two files, something has gone wrong. In that case, back up all files and start over.

The biggest 256-bit unsigned int is a useful default as deposit limits and the max number of TokenNetwork contracts.

(env) $ export MAX_UINT256=115792089237316195423570985008687907853269984665640564039457584007913129639935

The RPC connection point is used often.

(env) $ export PROVIDER="http://127.0.0.1:8545"

Deploy contracts

Now we can start deploying the Raiden smart contracts on the private chain.

(env) $ pwd
<snip>/priv_chain
(env) $ python -m raiden_contracts.deploy raiden --rpc-provider $PROVIDER --private-key $PRIV_KEY --gas-price 10 --gas-limit 6000000 --contracts-version $VERSION --max-token-networks $MAX_UINT256
{
    "EndpointRegistry": "0x6c9c647B37dC96a9916306db39403917f2deE247",
    "SecretRegistry": "0x6436d3B7205F18044a320403b1Cd0FfFd7e5D998",
    "TokenNetworkRegistry": "0xC5e4a9189ac801077317CD6BCFA643677897D15B"
}

We will use the address of TokenNetworkRegistry later, so let’s remember it.

(env) $ export TokenNetworkRegistry="0xC5e4a9189ac801077317CD6BCFA643677897D15B"

Before we deploy the other contracts, we need a token contract for service payments.

(env) $ python -m raiden_contracts.deploy token --rpc-provider $PROVIDER --private-key $PRIV_KEY --gas-price 10 --gas-limit 6000000 --token-supply 10000000000 --token-name ServiceToken --token-decimals 18 --token-symbol SVT --contracts-version $VERSION
{
“CustomToken”: “0xC5e9F7407359d1492d515C303A3aeDB434D3f0e1”

}

We use the address of this token to deploy service contracts.

(env) $ export SERVICE_TOKEN="0xC5e9F7407359d1492d515C303A3aeDB434D3f0e1"
(env) $ python -m raiden_contracts.deploy services --rpc-provider $PROVIDER --private-key $PRIV_KEY --gas-price 10 --gas-limit 6000000 --token-address $SERVICE_TOKEN --user-deposit-whole-limit $MAX_UINT256

We deploy another Token contract that’s going to be transferred on Raiden network.

(env) $ python -m raiden_contracts.deploy token --rpc-provider $PROVIDER --private-key $PRIV_KEY --gas-price 10 --gas-limit 6000000 --token-supply 10000000000 --token-name Token --token-decimals 18 --token-symbol TKN --contracts-version $VERSION
{
    "CustomToken": "0x818cBB172D1a1b769acaA94e80e4c71ba40bdc79"
}

We register this token to the TokenNetworkRegistry.

(env) $ export TOKEN="0x818cBB172D1a1b769acaA94e80e4c71ba40bdc79"
(env) $ python -m raiden_contracts.deploy register --rpc-provider $PROVIDER --private-key $PRIV_KEY --gas-price 10 --gas-limit 6000000 --token-address $TOKEN --token-network-registry-address $TokenNetworkRegistry --contracts-version $VERSION --channel-participant-deposit-limit 10000000 --token-network-deposit-limit 1000000000

Start Raiden Client

Find the relevant contract addresses and you can start the Raiden client:

(env) $ export EndpointRegistry=0xb145DF6d93EdB61280E4c5c9a3Abb853c329a43D
(env) $ export SecretRegistry=0xbF45e5a082Be39692c800D985e9c45F49aE26d69
(env) $ export TokenNetworkRegistry=0x2f7C7bbF10bCEe496F42F1eaB87Ab50a48FdBa61
(env) $ export Address=0x8AE8A9d3074CAdf540506FFEdca8A3a9da4f0e71
(env) $ raiden --datadir exchange-a  --keystore-path   ./blkchain1/keystore/ --network-id 4321  --accept-disclaimer --address $Address --rpc --api-address 0.0.0.0:5001 --web-ui  --environment-type development  --password-file passwd_file  --console --no-sync-check --accept-disclaimer --tokennetwork-registry-contract-address $TokenNetworkRegistry --secret-registry-contract-address  $SecretRegistry --endpoint-registry-contract-address $EndpointRegistry  #--gas-price 10000000000
