Wanchain 5.0 Testnet User Guide for Storeman Nodes
Wanchain 5.0 Testnet will be fully open for public testing on September 30th, 2020.
Wanchain 5.0 Testnet Bounty Program:
https://medium.com/wanchain-foundation/wanchain-5-0-testnet-bounty-program-a820162ee030
Wanchain 5.0 Testnet Bug Report:
1. Background Knowledge
The cross-chain mechanism of Wanchain actually builds a WAN Bridge between two public chains, so that assets on one chain can be integrated into another chain, and vice versa. At the core of a WAN Bridge is a Storeman Group connecting two public chains. Each Storeman Group is a WAN Bridge, and each Storeman Group contains 21 Storeman nodes.
The entire workflow of a Storeman Group is as follows:
In short, for a Storeman, you need to pay attention to the whole workflow. You should register a Storeman, try your best to be among the top 21 Storeman nodes so as to enter the Storeman Group, provide cross-chain services in the Storeman Group running period, and finally decide whether to enter the next round of Storeman node elections before the Storeman Group is dissolved.
Key parameters:
For the first Storeman Group cycle, you can prepare from September 30th to October 8th. If you are selected into the Storeman Group, you have to set up your server between October 9th & 11th. The Storeman Group will be running form October 11th to 16th. We plan to complete three cycles during Wanchain 5.0 Testnet.
2. Download Official Wanchain Desktop Wallet
Download official Wanchain Desktop Wallet test version for Wanchain 5.0 Testnet, and generate a WAN address to receive WAN test coins.
Note: please don’t send your mainnet WAN to this test version of WanWallet.
https://www.explorewanchain.org/#/wallet_and_tools/wan-wallet
Note: Considering the compatibility issue between the new and the old wallets, we highly suggest you backup and reset your wallet and clear local data.
Please ensure that you have backed up the seed phrase of your previous wallet.
If the wallet fails to start up, it is receomended to rename the folder “Wan Wallet” as a backup, and then restart your wallet. Take Windows 10 as an example:
Go to Open Data Folder from your WanWallet menu
Go back to the folder Roaming, and rename the folder Wan Wallet
Finnally, restart your wallet.
3. Apply For WAN Test Coins
For Storeman nodes, we provide a WAN test coins website where you can apply for a large amount of WAN test coins. The applicant must register his/her information, and answer 5 questions related to Wanchain. According to the number of correct answers, WAN test coins will be randomly distributed to your WAN address, ranging from 10,000 WAN to 100,000 WAN. The more questions you answer correctly, the greater number of WAN test coins you will get.
Website for large amount WAN test coins application:
https://storeman-form.vercel.app/
You will immediately receive WAN test coins ranging from 10,000 WAN to 100,000 WAN after you submit the application form online.
4. Storeman Nodes’ Staking & Competition
For the Storeman nodes who participate in the election, only top 21 Storeman nodes with biggest staking amount will be selected. Considering the cost of cloud servers, you can run the scripts in your local Linux Operating System to obtain a Validator Address (transfer your WAN test coins to this address to automatically participate in the Storeman node election), Validator Public Key (your Storeman registration in WanWallet will be used), EnodeId String (your Storeman registration in WanWallet will be used), Keystore JSON String (copy the contents to the same path of cloud server after the cloud server starts), and Nodekey String (copy the contents to the same path of cloud server after the cloud server starts).
If you already have a cloud server you can use, you can run the scripts directly on the cloud so as to reduce the step of copying files from local machine to the cloud server.
4.1 Generate Public Key and EnodeID
Run the scripts in Linux
Rename or delete the folder osm if it has already existed in the path /home/user
wget https://raw.githubusercontent.com/wanchain/two-way-bridge-contracts/master/helpscript/envSetup.sh && chmod +x envSetup.sh && ./envSetup.shAfter you run the scripts above, there will be a folder osm generated in /home/user. The folder osm will be used once you start establish your Storeman node.
Back up the script output
Note:
The contents marked in Bold will be used once you register your Storeman in WanWallet.

4.2 Stake WAN to Storeman node using WanWallet Desktop
Go to Storeman staking page
Open WanWallet Desktop, go to Storeman > Storeman. This is the page for your Storeman to stake. Please transfer small amount of WAN to your Validator Address for gas fees for the future to use when the Storeman Group is running. The transaction will fail if the validator address has 0 WAN.
Become a Storeman Candidate
When Wanchain Foundation sends a transaction to begin a new Storeman Group, you can see what Storeman Group that is available to receive what staking amount in the Open Group List.
Input your Public Key and Enode ID you generated
Select the account which you want to stake from and the amount of WAN you want to stake. After you confirm this information, you can see your staking details in the Storeman List.
Top-up your Storeman Candidate
After your Storeman becomes a Candidate, you can see the ranking of all Storeman Nodes, and top-up your funds to your Storeman in WanWallet.
5. Setup Storeman Node
5.1 Check Election Result
You can check the Storeman election result in the wallet. If the Status is Selected, it means that your Storeman node successfully entered the Storeman Group. If the Status is Not Selected, it means that your Storeman node failsed to enter the group.
The Storeman nodes which fail to be selected can claim back their staking funds.
5.2. Setup Storeman Node on Cloud
Hardware Requirements
To setup a Storeman node needs independent public IP. You can use cloud service or setup your own server. Linux OS is recommended. The following table is the minimum requirements of AWS for your reference.
Prepare Keystore and Nodekey
Please copy the files of Keystore and Nodekey which were generated in the path of /home/user of your local machine to the same path of your cloud server. (See Section 5 for how to generate Keystore and Nodekey)
5.3 Install Storeman Service
Initialize the environment
- Open Port
Log in Storeman management platform. Enable the following ports in the firewall inbound settings: TCP 37718/UDP 37718, and enable the following ports in the firewall outbound settings: TCP 26891/ TCP 26892/ TCP 30000. (If you run your own node, please add a corresponding port)
Initialize the environment
sudo chown "$USER" ~/osm
cd ~/osm
wget https://raw.githubusercontent.com/wanchain/two-way-bridge-contracts/master/helpscript/init_open_storeman_Env.sh && chmod +x init_open_storeman_Env.sh && ./init_open_storeman_Env.sh
wget https://raw.githubusercontent.com/wanchain/two-way-bridge-contracts/master/helpscript/startStoreman.sh && chmod +x startStoreman.sh- Get host ip as mongo ip through ifconfig
According to the picture above, host docker ip is 172.17.0.1
- Please manually create the password file of workAddress. The path is ~/osm/pwd.json. You should enter the corresponding password:
{
"WORKING_PWD": "Your password for workAddress 0x733452e4b0b6e0ae2248b0b46918d64bc8771bf2"
}Configure Mongo DB
- Modify the config file mongod.conf to make it available to access
sudo vi /etc/mongod.confAdd 172.17.0.1 to bindIp. It is host docker IP.
Restart Storeman Agent
- Restart MongoDB
sudo systemctl restart mongod- Confirm startStoreman.sh
# Confirm the parameters in the scripts are the parameters you required
# agent work path
workPath="$HOME/osm"
# mpc p2p port
# Make sure that p2pPort and the filrewall inbound port are consistent
p2pPort=37718
# If you want to manually configure the node, please modify the url
chain1='ETH'
url1='http://52.34.91.48:36892'
chain2='WAN'
url2='http://35.162.176.235:36891'
# You can configure your Storeman
# You can choose one of the following item for url2 to achieve load balance
# url2=' http://54.245.68.144:36891'
# url2=' http://18.237.192.57:36891'
# url2=' http://35.162.176.235:36891'
# url2=' http://34.222.238.177:36891'
# url2=' http://34.221.243.60:36891'- Start Agent
Waddress is the workAddress that your Storeman participates
As a docker, Hostip is used to connect mongoDB IP.
cd ~/osm/
./startStoreman [waddress] [hostip]
Example：./startStoreman.sh 0x733452e4b0b6e0ae2248b0b46918d64bc8771bf2 172.17.0.1- Check Agent Container Status
sudo docker exec -it openstoreman pm2 lStatus is online and restart times is 0 represents normal status.
View your log using following command lines
# agent log
sudo docker exec -it openstoreman pm2 log 0
# mpc log
sudo docker exec -it openstoreman pm2 log 1- Verify the connection number of Storeman Peer
Open mpc console through ipc, and check the number of connected MPC nodes in console
sudo docker exec -it openstoreman ./schnorrmpc/bin/schnorrmpc attach ./schnorrmpc/data/gwan.ipc
>admin.peers.lengthConfirm the returned peer node information, which indicates the current number of MPC node connections.
6. Storeman Group Running Period
6.1 Top-up Staking Amount
During the period of Storeman Group working, you can top-up WAN to your Storeman.
6.2 Claim Rewards
You can claim your rewards every day. But the deposits can only be claimed when the entire Storeman Group completes.
6.3 Exit
You can choose to enter the next round of electoion or exit the election before the next round of Storeman Group starts.
You can top-up your staking amount at any time during the cycle of Storeman Group operation. (Note: in the testnet, a cycle is 5 days, while in the mainnet, a cycle is 45 days, up to current rule).
After a cycle of Storeman Group completes, you can claim your both deposits and rewards, and enter the next round of election.
