+# Start a Logos blockchain node
+
+Applies to: https://github.com/logos-blockchain/logos-blockchain @ <!-- TODO: tag or commit SHA -->
+Runtime target: Logos testnet v0.1
+Last checked: <!-- TODO: YYYY-MM-DD -->
+Status: Stub
+Owner: @davidrusu
+Tracking: https://github.com/logos-co/logos-docs/issues/171
+
+## Outcome + value
+
+- **Outcome (end goal):** A running logos blockchain node participating in consensus and proposing blocks
+- **Why it matters:** Participating in consensus is the primary method for securing and decentralizing the network.
+
+## Audience
+
+- Node operator
+
+## Known gaps / Blockers
+
+- Doc Packet missing: runnable steps, expected outputs, v0.1 limits
+- Notion source needs mapping: https://nomos-tech.notion.site/Internal-Devnet-Launch-February-2026-2fe261aa09df8025ad94e380933b4cf9
+
+## Prerequisites
+
+- OS: macOS, Linux x86_64
+- Dependencies: [Nix](https://nixos.org/download/)
+- Accounts/keys: <!-- TODO: e.g. validator key, staking key -->
+- Network/chain: <!-- TODO: chain ID, network name, endpoints -->
+- Other: <!-- TODO -->
+
+## Hardware requirements
+
+- Target devices: <!-- TODO: e.g. x86_64 computer -->
+- Minimum: <!-- TODO: CPU, RAM, storage (type + free space), network -->
+- Recommended: <!-- TODO: CPU, RAM, storage, network -->
+- Storage profile: <!-- TODO: expected disk growth / SSD required? -->
+
+## Configuration
+
+- Env vars:
+  - <!-- TODO: NAME=example - purpose -->
+
+- Flags:
+  - <!-- TODO: flag - purpose -->
+
+- Config file keys:
+  - <!-- TODO: key=example - purpose -->
+
+- Default endpoints/ports:
+  - <!-- TODO: port/proto - what uses it -->
+
+## Steps (happy path)
+
+<!-- TODO: Copy/paste sequence from an empty machine to "it works" (include exact commands). -->
+
+### Run the blockchain UI app
+
+1. Clone the repository:
+
+   ```sh
+   git clone https://github.com/logos-blockchain/logos-blockchain-ui.git
+   cd logos-blockchain-ui
+   ```
+
+2. Build the standalone app:
+
+   ```sh
+   nix build '.#app'
+   ```
+
+   > If you don't have flakes enabled globally, add experimental flags:
+   >
+   > ```sh
+   > nix build --extra-experimental-features 'nix-command flakes' '.#app'
+   > ```
+
+3. Run the app:
+
+   ```sh
+   ./result/bin/logos-blockchain-ui-app
+   ```
+
+### Generate a node config
+
+4. Copy the initial trusted peer set from the latest [Logos blockchain release notes](https://github.com/logos-blockchain/logos-blockchain/releases), paste it into the trusted peers field, and click **Generate Config**. The output will include the path to the generated config file.
+
+5. Click **Load Config** and select the config file from the path shown in the previous step.
+
+6. Click **Start Node** to start the node.
+
+### Request tokens from the faucet
+
+7. Copy one of the keys from your wallet, which is now visible in the UI after starting the node.
+
+8. Go to the [devnet faucet](https://devnet.blockchain.logos.co/node/0/faucet), paste your key, and click **Request Funds**.
+
+   > It may take up to a minute for the transaction to go through and for the funds to appear in your wallet.
+
+### Participate in consensus
+
+Once funded, your node will automatically participate in the consensus lottery and start producing blocks. The UTXO needs to age before it becomes eligible, which takes approximately 2 hours.
+
+## Expected outputs
+
+- After step 3 (run the app): A window opens displaying buttons for **Start Node**, **Load Config**, and **Generate Config**.
+- After step 4 (generate config): The UI displays a message confirming the config was written, along with the file path.
+- After step 6 (start node): A green indicator shows the node is running and the wallet appears displaying a balance of 0.
+- After step 8 (request funds): The faucet displays a success message with the transaction hash. After up to a minute, the wallet updates to show a balance on the requested public key.
+- After consensus participation: <!-- TODO: no way to observe block production yet -->
+
+## Verify
+
+- Check that the blockchain height is increasing:
+
+  ```sh
+  curl localhost:8080/cryptarchia/info
+  ```
+
+  Example response:
+
+  ```json
+  {"lib":"3d0c...4e6d","tip":"f44d...e2f5","slot":70899,"height":120,"mode":"Bootstrapping"}
+  ```
+
+  You should see the `height` increasing at an average rate of 1 block every 10 seconds. The timing is probabilistic, so expect some variance.
+
+- Check that your node is connected to peers:
+
+  ```sh
+  curl localhost:8080/network/info
+  ```
+
+  Example response:
+
+  ```json
+  {"listen_addresses":["/ip4/127.0.0.1/udp/3001/quic-v1"],"peer_id":"12D3...fuS2","n_peers":16,"n_connections":19,"n_pending_connections":0}
+  ```
+
+  Verify that `n_peers` is greater than 0.
+
+## Troubleshooting (top 3-5)
+
+- Symptom: Balance not updating after requesting funds from the faucet.
+  Cause: Only one faucet transaction can be included per block. During high demand, your transaction may be dropped.
+  Fix/workaround: Retry the request from the faucet.
+
+## Limits (for Testnet v0.1)
+
+- Not supported: Dynamic wallet key management. To add new keys, you must manually edit the config file and restart the node.
+- Known issues/sharp edges: No key generation tooling exists yet.
+- Minimal information is displayed in the node UI. Users need to query the HTTP API (e.g. `/cryptarchia/info`, `/network/info`) to check chain health and node status.
+- Block rewards are not yet visible through the UI.
