Set up the node first. Then point Braiins at it. Build blocks on OCEAN.
Guide for setting up a DATUM node first, then using Braiins hashpower to point at it and make your own blocks on OCEAN.
Start with one node guide. Once that guide leaves you with a working DATUM endpoint, move to the shared Braiins guide and create the bid there.
What you are actually doing
This is a 2-step workflow
First you finish one node setup guide and make DATUM reachable. Then you use the shared Braiins guide once, with the endpoint and username details from the node guide you chose.
Step 01
Pick one node setup and make DATUM reachable
Use the VPS guide if you are starting from zero and want the path that fits the most people. If you already run StartOS or Umbrel hardware you trust, it usually makes more sense to use that guide instead. That guide should leave you with a synced node, a running DATUM gateway, and a public endpoint or hostname that Braiins can actually reach.
Step 02
Use the Braiins guide once the node is ready
The Braiins side is shared: create the account, fund it, enter the right mining pool URL, and use the correct username format without typos.
Step 1
Choose the node setup that matches your situation
The VPS guide is the best default if you are starting from zero and want the path that fits the most people. If you already have StartOS or Umbrel running at home, it usually makes more sense to use that instead.

Fresh VPS node setup for DATUM
Rent a Linux VPS, install the combined node + DATUM box, and get a public DATUM endpoint ready for Braiins.

Reuse StartOS, install the right packages, and expose DATUM through Start Tunnel or a stable static public IP.

Reuse Umbrel, install Bitcoin Knots and DATUM, then expose DATUM on port 23334.
Step 2
Use the shared Braiins guide once the node is ready
The Braiins side is separate. Once your node guide gives you a working public DATUM endpoint, use the shared Braiins guide to create the account, fund it, and create the bid.
Before funding
Use the calculator to compare the expected hashpower result against simply buying BTC at spot before you send sats into Braiins.
