Wanchain 5.0 Mainnet User Guide for Storeman Nodes

Published by Liam on

A step by step guide for setting up a Storeman node on the Wanchain mainnet

!!!!!! IMPORTANT NOTES !!!!!!
1) Storeman registration runs from November 10th to November 19th, make sure you have registered by November 19th (Step 2.2)! Don’t miss your chance to make history as part of the first permissionless wanBridge!

2) After setting up your node, please fill in this form in order to have your node information displayed properly on the Wanchain explorer Website and other official informational sites and applications.
!!!!!! IMPORTANT NOTES !!!!!!

Step 1) Download & Install Official Wanchain Desktop Wallet

WanWallet Desktop Download link

Make certain your seed phrase is backed up

2. Storeman Selection

In order to form a wanBridge, 21 Storeman nodes must work together. In order to choose which 21 nodes may form a wanBridge, there is a selection process based on the amount of stake in each node. The 21 nodes with the most WAN staked will be selected. In order to be considered for selection, node operators must register their node with a on-chain transaction.

Summary of the Storeman setup process:

Run scripts to obtain a Storeman Work Address , Public Key (your Storeman registration in WanWallet will be used), EnodeId String (your Storeman registration in WanWallet will be used), and back up the folder generated by the scripts.

2.1 Generate Public Key and EnodeID

Run scripts in Linux Ubuntu environment, and make sure the environment is safe

Rename or delete osm if it already exists at /home/user

wget [https://raw.githubusercontent.com/wanchain/two-way-bridge-contracts/master/helpscript/envSetup.sh](https://raw.githubusercontent.com/wanchain/two-way-bridge-contracts/master/helpscript/envSetup.sh) && chmod +x envSetup.sh && ./envSetup.sh

After you run the scripts above, there will be a folder osm generated at /home/user. The folder osm will be used when you start your Storeman node.

Backup BOTH the script output and also the osm folder. If you are running these scripts locally, you will later need to copy the osm folder generated by these scripts to your cloud server.

Note:
The contents marked in bold will be used once you register your Storeman in WanWallet.

2.2 Stake WAN using WanWallet Desktop

A) Go to the Storeman staking page

Open WanWallet Desktop, go to Storeman > Storeman. This is the page for your Storeman to stake. Please transfer a small amount of WAN to your Storeman Work Address for gas fees which are required for your node to operate. The transaction will fail if the validator address has 0 WAN.

B) Register as a Storeman Candidate

After the Wanchain Foundation sends a transaction to begin a new Storeman Group, it will be visible in the Open Group List:

Input the Public Key and Enode ID you generated by the previously run script

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.

Add Additional Stake or Attract Delegations to Increase Selection Chances

After your Storeman becomes a Candidate, you can see the ranking of all Storeman Nodes, and top-up funds in theWanWallet.

You can also accept delegations from individuals in order to increase your chance of getting selected.

3. Check Selection Results, and Set Up Storeman Node if Selected

3.1 Check Election Result

You can check the Storeman selections results directly through the desktop 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 failed to enter the group.

The Storeman nodes which fail to be selected can claim back their WAN.

3.2. Cloud Server Setup

Recommended Specifications:

A public IP without a proxy is required. Cloud and bare metal servers are both supported. The following table shows the requirements:

Prepare Keystore and Nodekey

If you ran the setup scripts locally, please copy the Keystore and Nodekey files which were generated at /home/user to the same path on your cloud server. (See Section 2 for how to generate Keystore and Nodekey)

3.3 Install Storeman Service:

a) Transfer Small Amount of WAN to Work Address

Double check you have already transferred a small amount of WAN to your Storeman Work Address for gas fees. The transaction will fail if the Storeman work address has 0 WAN.

b) Environment Setup:

Open Ports:

Log in to your cloud server platform (such as AWS). 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 modify the ports of the scripts, please add the related port in your firewall.

Initialize the environment:

sudo chown $USER ~/osm
rm init_open_storeman_EnvV3.sh
wget [https://raw.githubusercontent.com/wanchain/two-way-bridge-contracts/master/helpscript/init_open_storeman_EnvV3.sh](https://raw.githubusercontent.com/wanchain/two-way-bridge-contracts/master/helpscript/init_open_storeman_EnvV3.sh) && chmod +x init_open_storeman_EnvV3.sh && ./init_open_storeman_EnvV3.sh
rm startStoremanV3.sh
wget [https://raw.githubusercontent.com/wanchain/two-way-bridge-contracts/master/helpscript/startStoremanV3.sh](https://raw.githubusercontent.com/wanchain/two-way-bridge-contracts/master/helpscript/startStoremanV3.sh) && chmod +x startStoremanV3.sh

c) Configure KMS

Users can use shared key fragments through KMS. (It is highly recommended as it will greatly enhance the security of your funds).

If you skip this part, you can go to Section d) Start Storeman Agent.

Record the information listed below as you go throught the following steps:

User Access key ID: AKIAJPUJ*****

User Secret Access Key: KiHjz0g12a*****

KMS Key Region: us-east-1

KMS Key ID (ARN): arn:aws:kms:us-east-1: :key/

AWS KMS Setup

Create an AWS user (mpc)

Log in to AWS console and go to services. Then select “IAM”. On the left side you can see a section called “Users”

Save your User Access key ID and Secret Access Key:

Create AWS KMS secret:

The primary resources in AWS KMS are customer master keys (CMKs). CMKs are either customer managed or AWS managed. Let’s take a look at how to create a customer master key in AWS.

Log in to AWS console and go to services. Then select “Key Management Service (KMS)”. On the left side you can see a section called “Customer managed keys”. Navigate to that section. Then select “Create Key” on top left.

Follow the steps as follows:

Please record the following two pieces of information from ARN (Amazon Resource Name):

KMS Key Region: us-east-1

KMS Key ID (ARN): arn:aws:kms:us-east-1: :key/

d) Start Storeman Agent

cd ~/osm/ 
./startStoremanV3.sh

e) Check Agent Container Status

sudo docker exec -it openstoreman_mainnet pm2 l

Status of online and restart times of 0 represent normal status.

View your log using following commands:

# agent log 
sudo docker exec -it openstoreman_mainnet pm2 log 2 
# mpc log 
sudo docker exec -it openstoreman_mainnet pm2 log 1

f) Verify the connection number of Storeman Peers

Open mpc console through ipc, and check the number of connected MPC nodes in console:

sudo docker exec -it openstoreman_mainnet ./schnorrmpc/bin/schnorrmpc attach ./schnorrmpc/data/gwan.ipc 
admin.peers.length

Confirm the returned peer node information, which indicates the current number of MPC node connections. It should be more than 0.

4. Storeman Group Running Period

4.1 Top-up Stake

During the Storeman Group working period, you can top-up WAN to your Storeman.

4.2 Claim Rewards

You can claim your rewards every day. But the deposits can only be claimed when the entire Storeman Group period has concluded.

4.3 Exit

You can choose to enter the next round or exit the selection process before the next Storeman Group is formed.

You can top-up your staking amount at any time. (

(Note: in the testnet, a cycle is 5 days, while in the mainnet, the first cycle is 49 days , following cycles will be 30 days— cycle time subject to change in future)

After a cycle completes, you can claim your both deposits and rewards, and enter the next round.

5. How To Delegate WAN To A Storeman

Find the Delegation button:

Click on New Delegation, and choose a Storeman to delegate to:

You can also top-up WAN delegations to the same Storeman during the Storeman Group running period. You can withdraw your rewards each day. After a cycle completes, you can withdraw both deposits and rewards.

Please note that the delegation amount to a Storeman can increase this Storeman’s weight. But the rewards will only be counted after the Storeman Group starts working.
