以下内容在ubuntu机器，Ropsten测试网络实测ok。

注意：随着Raiden开发的不断推进，本文内容有可能不适用未来最新版本

Raiden 环境搭建

1. 下载Raiden执行文件
wget
https://github.com/raiden-network/raiden/releases/download/v0.1.0/raiden--x86_64.AppImage
mv raiden--x86_64.AppImage raiden chmod +x raiden
2. 安装Parity 客户端
wget
https://parity-downloads-mirror.parity.io/v1.7.6/x86_64-unknown-linux-gnu/parity_1.7.6_amd64.deb
dpkg -i parity_1.7.6_amd64.deb
3. 准备账号
parity account new --chain ropsten --keys-path
~/.local/share/io.parity.ethereum/keys/ethereum/
新建两个eth账户。Raiden节点使用eth地址来标识。

下文假设A账户为0x607f1724469a0beeed74e1429c3c5adcf8290fa3，B账户为0x17cb47f30f844b6969e8cc6cd3c506eb25f17819。

4. 启动Parity 同步ropsten 测试网络
#parity db kill --chain ropsten parity --geth --keys-path
~/.local/share/io.parity.ethereum/keys/ethereum/ --chain ropsten --bootnodes
"enode://20c9ad97c081d63397d7b685a412227a40e23c8bdc6688c6f37e97cfbc22d2b4d1db1510d8f61e6a8866ad7f0e17c02b14182d37ea7c3c8b9c2683aeb6b733a1@52.169.14.227:30303,enode://6ce05930c72abc632c58e2e4324f7c7ea478cec0ed4fa2528982cf34483094e9cbc9216e7aa349691242576d552a2a56aaeae426c5303ded677ce455ba1acd9d@13.84.180.240:30303"
parity默认已开启Warp sync。等待网络同步完成再执行后面的操作。否则raiden启动的时候会报Raiden的Registry合约无法找到的错误。

5. 在Ropsten给账号增加以太balance

因为raiden中加入网络和建立通道都需要发送交易，所以要求对应账户的eth余额不能为0。

打开 http://faucet.ropsten.be:3001/ <http://faucet.ropsten.be:3001/>
给4中的账户发送ether。

6. 启动Raiden

配置不同的端口，启动两个节点：
./raiden --keystore-path ~/.local/share/io.parity.ethereum/keys/ethereum/test/
--api-address 0.0.0.0:9545 --listen-address 0.0.0.0:4001 ./raiden
--keystore-path ~/.local/share/io.parity.ethereum/keys/ethereum/test/
--api-address 0.0.0.0:9546 --listen-address 0.0.0.0:4002
选择不同的账户，并输入密码解锁。

正常启动情况下会输出API端口信息。

<https://github.com/toxotguo/thinking/blob/master/images/raiden_start.png>

后面与Raiden都是通过Restful API来交互。

7. 检查是否运行正常
curl http://127.0.0.1:9545/api/1/address #返回 {"our_address":
"0x607f1724469a0beeed74e1429c3c5adcf8290fa3"} curl
http://127.0.0.1:9546/api/1/address #返回 {"our_address":
"0x17cb47f30f844b6969e8cc6cd3c506eb25f17819"}
输出的地址与启动时候所选择的账户地址一致，则已正常运行。

至此，两个节点的Raiden环境已经搭建起来了。

节点交互

通过API可以向网络注册新的Token Network，也可以直接接入一个已注册的Token
Network，可以与其他Raiden节点建立Channel并Deposit到Channel，还有其他的一些相关操作。详细可以看Raiden 的API说明
<http://raiden-network.readthedocs.io/en/stable/api_walkthrough.html#> 。

Raiden提供了一个已注册好的Raiden Testnet Token (RTT)。RTT地址是
0x0f114a1e9db192502e7856309cc899952b3db1ed。

下面的内容是对部分API的简单体验过程。

1. 调用RTT合约转账给A、B账户使其先拥有RTT余额

使用web3.js调用以下代码发起账户转账RTT 代币�的交易。注意调用之前先解锁账户。
var addr='0x607f1724469a0beeed74e1429c3c5adcf8290fa3';#改成自己的账户地址 var
rtt_token_abi = Contract ABI;
#可以从https://ropsten.etherscan.io/address/0x0f114a1e9db192502e7856309cc899952b3db1ed#code
获取 var rtt_token_address = "0x0f114a1e9db192502e7856309cc899952b3db1ed"; var
rtt_token = web3.eth.contract(rtt_token_abi).at(rtt_token_address);
rtt_token.mint({from:addr}); // adjust to your raiden account and unlock first!
console.log(rtt_token.balanceOf(addr).toString());
每调用一次，RTT增加100。调用完之后，可以在https://ropsten.etherscan.io/address/账户地址
<https://ropsten.etherscan.io/address/%E8%B4%A6%E6%88%B7%E5%9C%B0%E5%9D%80>
查看交易状态。如果交易上链了，账户的RTT代币余额就会增加，可以多调几次，使得余额充足，方便后面的通道转账。

2. A、B节点自动连接RTT network（可选）
#对A节点 curl -X PUT -H "Content-Type: application/json" -d '{"funds":100}'
http://127.0.0.1:9545/api/1/connection/0x0f114a1e9db192502e7856309cc899952b3db1ed
#对B节点 curl -X PUT -H "Content-Type: application/json" -d '{"funds":100}'
http://127.0.0.1:9546/api/1/connection/0x0f114a1e9db192502e7856309cc899952b3db1ed
正常情况下输出状态变更事件消息：
INFO:raiden.network.rpc.client new_netting_channel called peer1=a6c07564

每个节点执行成功之后，节点就会自动加入RTT network并且与其他三个随机的节点建立状态通道，并且每个channel会deposit
20%的funds，剩余的40%funds留给新加进来的节点来建立状态通道。

如果是RTT余额不足，Raiden客户端会提示：
INFO:raiden.network.rpc.client new_netting_channel called peer1=1fb444d0
netting_channel=fd0a1d0e peer2=82710a71
3. A与B建立直接的状态通道
curl -X PUT -H "Content-Type: application/json" -d '{"partner_address":
"0x17cb47f30f844b6969e8cc6cd3c506eb25f17819","token_address":
"0x0f114a1e9db192502e7856309cc899952b3db1ed","balance": 100,"settle_timeout":
600}' http://127.0.0.1:9545/api/1/channels
其中partner_address是节点地址，即B节点地址，token_address是token地址，即RTT的地址。

正常建立情况下会有类似提示：
INFO:raiden.event_handler state_change received
state_change=<raiden.transfer.mediated_transfer.state_change.ContractReceiveNewChannel
object at 0x7f7f1ed34e50> INFO:raiden.network.rpc.client deposit called
amount=100 contract=721d03ec
4. A节点查看状态通道信息
curl -X GET http://127.0.0.1:9545/api/1/channels 返回： [ { "balance": 100,
"channel_address": "0x721d03ec76ccbfdce0ad3fc4602b59d622304d25",
"partner_address": "0x17cb47f30f844b6969e8cc6cd3c506eb25f17819",
"reveal_timeout": 10, "settle_timeout": 600, "state": "opened",
"token_address": "0x0f114a1e9db192502e7856309cc899952b3db1ed" } ] curl -X GET
http://127.0.0.1:9546/api/1/channels 返回： [ { "balance": 0, "channel_address":
"0x504750b7b1e0940119f3d0bad11e2fc766ab97a1", "partner_address":
"0x0c599ace7e0a7ff7c0ce6ba1c50f35ec58c04e86", "reveal_timeout": 10,
"settle_timeout": 400, "state": "opened", "token_address":
"0x0f114a1e9db192502e7856309cc899952b3db1ed" } ]
从返回可以看出，state为opened，状态通道中A余额为100，B余额为0。

5. 向状态通道deposit（可选）

从4 中可以看到B和A节点的状态通道的balance。也可以deposit。
curl -X PATCH -H "Content-Type: application/json" -d '{"balance":50}'
http://127.0.0.1:9545/api/1/channels/0x721d03ec76ccbfdce0ad3fc4602b59d622304d25
#注意是channel_address

6. A向B节点发起RTT转账1
curl -H "Content-Type:application/json" -X POST --data '{"amount":1}'
http://127.0.0.1:9545/api/1/transfers/0x0f114a1e9db192502e7856309cc899952b3db1ed/0x17cb47f30f844b6969e8cc6cd3c506eb25f17819#
节点地址
返回：
{ "amount": 1, "identifier": 6913515701748887592, "initiator_address":
"0x607f1724469a0beeed74e1429c3c5adcf8290fa3", "target_address":
"0x17cb47f30f844b6969e8cc6cd3c506eb25f17819", "token_address":
"0x0f114a1e9db192502e7856309cc899952b3db1ed" }
转账成功。

此时再次查询状态通道信息
curl -X GET http://127.0.0.1:9545/api/1/channels [ { "balance": 99,
"channel_address": "0x721d03ec76ccbfdce0ad3fc4602b59d622304d25",
"partner_address": "0x17cb47f30f844b6969e8cc6cd3c506eb25f17819",
"reveal_timeout": 10, "settle_timeout": 600, "state": "opened",
"token_address": "0x0f114a1e9db192502e7856309cc899952b3db1ed" } ] curl -X GET
http://127.0.0.1:9546/api/1/channels [ { "balance": 1, "channel_address":
