Kadena is a fast, secure, and scalable blockchain utilizing the Chainweb consensus protocol. Its innovative architecture allows for greater transaction throughput while ensuring the security typical of Bitcoin. In this guide, you’ll learn how to configure, run, and monitor a Chainweb node, just like how you would set up a brand-new bookcase to organize your library.

Kadena Docs Site

The Kadena Docs site serves as a comprehensive source of information where you can find details about interacting with the public chain, including how to get keys, view network activity, explore blocks, and more. Access the documentation here.

Installing Chainweb

To get started with Kadena, you’ll need to meet the minimal hardware requirements:

• 2 CPU cores
• 4 GB of RAM
• 250 GB SSD or fast HDD
• Public IP address

Using Docker (All Batteries Included)

A Docker image is available and can be set up with the following commands:

docker run -ti --rm -v chainweb-db:root.local/share/chainweb-node/mainnet010 kadena/chainweb-node chainweb-initialize-db.sh

To run a Chainweb node in Kadena’s mainnet:

docker run -d -p 443:443 -v chainweb-db:target=root.local/share/chainweb-node/mainnet010 kadena/chainweb-node

Bootstrap Nodes

Bootstrap nodes help Chainweb nodes discover others in the network. Here are a few:
– Testnet: us1.testnet.chainweb.com
– Mainnet: us-e1.chainweb.com

Configuring, Running, and Monitoring the Health of a Chainweb Node

Once you have the Chainweb node binary installed, you can start it by running:

chainweb-node

Ensure that your node is accessible from the public internet. You’ll need to configure port forwarding if your machine is behind a router.

To monitor the health of your node, run:

curl -sk https://{public-ip}:{port}/chainweb/0.0/mainnet01/cut

Replace `{public-ip}` and `{port}` with your actual values. If your node is functioning properly, you’ll receive details about the latest cut (block) from the network.

Mining for a Chainweb Network

Successful mining requires specialized hardware (ASIC). You will also need to set up a Chainweb node and connect it with the mining API. Detailed steps can be found in the documentation of the chainweb-mining-client.

Chainweb Design

Chainweb consists of multiple components that function together to deliver its unique capabilities:

• chainweb library: Implements various components.
• chainweb-node: Runs the node maintaining copies of multiple chains.
• chainweb-tests: A test suite for quality assurance.
• cwtool: Tools for maintaining and debugging.
• bench: A collection of benchmarks.

Troubleshooting

While setting up your Kadena node, you might encounter a few hiccups. Here are some troubleshooting ideas:

• Check your hardware specifications to make sure they meet the minimum requirements.
• Ensure that necessary ports (1789 for P2P, 1848 for service APIs) are open and correctly forwarded.
• If synchronization is slow, consider utilizing the initialize database command to avoid long initial sync times.
• Review your Docker and network configurations carefully.
