Through this guide we will setup DMND Stratum V2 client and connect to DMND pool. After completing this guide, you will have a fully functional Stratum V2 mining setup connected to DMND pool with full Job Declaration.

To mine with DMND pool you must first obtain DMND token. Please complete the registration form at https://onboarding.dmnd.work and await our confirmation email before proceeding.

To use Stratum V2 with Job Declaration, you must run Bitcoin Core along Stratum V2 Template Provider. Job declaration is one of the key features of Stratum V2 that allow miners to build their own blocks, improving decentralization, efficiency, and latency.

What you need:

• Bitcoin Core(At least version 30) with IPC enabled.
• Stratum V2 Template Provider, which connect to Bitcoin Core via IPC and provide templates to the DMND Stratum V2 Client.

Follow instruction to download and install Bitcoin Core as describe in the official website:

https://bitcoincore.org/en/releases/30.0/

Then make sure to start Bitcoin Core with IPC enabled.

bitcoin -m node -chain=main -ipcbind=unix

Note that the ipcbind=unix is required and Stratum V2 will not work without it.

Download the Template Provider binary. https://github.com/stratum-mining/sv2-tp/releases/tag/v1.0.5

Run the Template Provider:

sv2-tp -debug=sv2 -loglevel=sv2:trace

If you have changed Bitcoin Core’s default datadir, you may need to specify the Unix socket path manually by adding the following option:

-ipcconnect=unix:<path-to-bitcoin-dir>/node.sock

The default Template Provider port is 8336.

You can download the latest release of DMND Stratum V2 Client from: https://github.com/dmnd-pool/dmnd-client/releases/tag/v0.2.2

Assuming that dmnd-client-linux is the executable you are using, run:

TOKEN=<DMND-token> cargo run -- -l info -d <avg-hashrate>T --tp-address="127.0.0.1:<port>"

Where:

• <avg-hashrate> = average hashrates of all your miners in TH/s. For example, if you have three machines of 100Th/s, 200Th/s and 300Th/s, then the average hashrate is (100 + 200 + 300) / 3 = 200 TH/s. Our dynamic difficulty adjustment algorithm will take care of the rest.

• <port> is the Template Provider listening port (default 8336).

• <DMND-token> is the token you received via email from DMND pool during registration.

Example:

TOKEN=abc123 cargo run -- -l info -d 200T --tp-address="127.0.0.1:8336"

After you have Bitcoin Core, Stratum V2 Template Provider and DMND Stratum V2 Client running, you can point your miner to the DMND Stratum V2 Client.

Leave the username and password fields empty in your miner configuration. And you should point the miners to the machine running the DMND Stratum V2 Client. If not changed, the default port of the DMND Stratum V2 Client is 32767. So you should obtain the IP address of the machine running the DMND Stratum V2 Client and point your miner to:

stratum+tcp://<machine_running_dmnd_client_ip>:32767

You can track your hashrate and earnings on the DMND pool dashboard:

https://dashboard.dmnd.work

Login with the same credentials you used during registration.

Happy Mining!
