echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/ubuntu \
  $(. /etc/os-release && echo "$VERSION_CODENAME") stable" | \
  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

Building a Node on Fuse with Nethermind client

Since 08.2022 Fuse is moving from OE client to Nethermind. To bootstrap Fuse archive node this guide covers the steps on how to build Nethermind from source and configure it to run for Fuse Network

Clone Fuse Repository

$ git clone https://github.com/fuseio/fuse-network.git ~/Dev/fuse-network

Download Quickstart

You can create an archival node using Quickstart.sh

# Enter the fuse-network folder
cd ~/Dev/fuse-network

# Download
wget -O quickstart.sh https://raw.githubusercontent.com/fuseio/fuse-network/master/nethermind/quickstart.sh

# Gain needed permissions
chmod 755 quickstart.sh

# Run Outline Example
./quickstart.sh -r [node_role] -n [network_name] -k [node_key]

# To create an archival node
./quickstart.sh -r explorer -n fuse -k [your_node_key_here]

Query Fuse Node

# To ensure your archival node has been correctly started, run the below
curl -X POST -H "Content-type: application/json" --data \
'{"jsonrpc":"2.0", "method":"eth_blockNumber", "params":[], "id":1}' \
http://localhost:8545

# Your result should resemble the following:
{"jsonrpc":"2.0","id":1,"result":"0xcab5ab"}

To access your archival node - use your current server's IP address with port 8545. Ex. http://localhost:8545

Check Docker Logs

# Get Container ID
docker ps

# Desired Image name should be "fusenet/node:nethermind"
# Copy the Container ID and check your logs
docker logs [Container_ID]
