# Running a Full Node ## Konstellation Mainnet Full Node Quick Start With each version of the Konstellation Hub, the chain is restarted from a new genesis state. We are currently on `darchub`. Get Mainnet Configuration files from [here.](https://github.com/Konstellation/konstellation/tree/master/config) ### **Hardware requirements** CPU: 8 core RAM: 32 GB DISK Storage: SSD 500 GB \~ 2 TB ### Build from code This guideline assumes that you're running Linux or MacOS with [Go 1.18+](https://golang.org/dl/). This guide helps you to : Build, Install, and Name your Node. Currently, latest release is `v0.6.2` ``` # Clone Konstellation from the latest release found here: https://github.com/konstellation/konstellation/releases git clone -b v0.6.2 https://github.com/konstellation/konstellation # Enter the folder Konstellation was cloned into cd konstellation # Compile and install Konstellation make build # alias binary file # alias knstld=/your/path/to/repo/build/knstld # Check konstellation version knstld version ``` **Initialize data and folders** **WARNING** : command `unsafe-reset-all` will erase your database in node directory if exists, which is `$HOME/.knstld` if no customs have been made. If you are already running validator, be sure to back up your `priv_validator_key.json` in `$HOME/.knstld/config` directory. Though this command won't erase the file, it has to be backed up in somewhere safe. ``` # Reset current node's data knstld tendermint unsafe-reset-all --keep-addr-book ``` #### Create a key Add new ``` build/knstld keys add ``` Or import via mnemonic ``` build/knstld keys add -i ``` As a result, you got ``` - name: type: local address: pubkey: mnemonic: "" threshold: 0 pubkeys: [] **Important** write this mnemonic phrase in a safe place. It is the only way to recover your account if you ever forget your password. ``` **Genesis & Seeds** Download [genesis.json](https://raw.githubusercontent.com/Konstellation/konstellation/master/config/genesis.json) ``` wget -O $HOME/.knstld/config/genesis.json https://raw.githubusercontent.com/Konstellation/konstellation/master/config/genesis.json ``` Download [config.toml](https://raw.githubusercontent.com/Konstellation/konstellation/master/config/config.toml) with predefined seeds and persistent peers ``` wget -O $HOME/.knstld/config/config.toml https://raw.githubusercontent.com/Konstellation/konstellation/master/config/config.toml ``` Alternatively enter persistent peers to config.toml provided [here](https://github.com/Konstellation/konstellation/tree/master/config) 1. Open \~/.knstld/config/config.toml with text editor. Alternatively you can use cli editor, like nano `nano ~/.knstld/config/config.toml` 2. Scroll down to persistant peers in `config.toml`, and add the persistant peers as a comma-separated list #### **Setting Up a New Node** You can edit this moniker, in the \~/.knstld/config/config.toml file: ``` # A custom human readable name for this node moniker = "" ``` You can edit the \~/.knstld/config/app.toml file in order to enable the anti spam mechanism and reject incoming transactions with less than the minimum gas prices: ``` # This is a TOML config file. # For more information, see https://github.com/toml-lang/toml ##### main base config options ##### # The minimum gas prices a validator is willing to accept for processing a # transaction. A transaction's fees must meet the minimum of any denomination # specified in this config (e.g. 10udarc). minimum-gas-prices = "" ``` Your full node has been initialized! #### Run Pruning Node Download Snapshot of previous blocks data Install lz4 if not installed ``` sudo apt update sudo apt install snapd -y sudo snap install lz4 ``` Check current height on [polkachu](https://polkachu.com/tendermint_snapshots/konstellation) and download snapshot // I think its not working right now. WIll test later 
# Download snapshot until current-height
wget -O konstellation_6445823.tar.lz4 https://snapshots.polkachu.com/snapshots/konstellation/konstellation_[current-height].tar.lz4 --inet4-only
# Unzip snapshot and move to database directory
lz4 -c -d konstellation_6445823.tar.lz4  | tar -x -C $HOME/.knstld
**Run a Full Node** ``` # Start Konstellation build/knstld start # to run process in background run screen -dmSL knstld build/knstld start # Check your node's status with konstellation cli build/knstld status ``` Wait for the konstellation block synchroniztion complete. Since this will take a lot of times and disk spaces, you may want to download snapshots. #### Block 1826999 At block 1826999 chain will halt, this is the upgrade requirement block. You will get an error ``` INF committed state app_hash=76B4066182CB3D3E984E09CB5226FD9734F0DFB91EA25AC4CFAC326D26E8D346 height=1826999 module=state num_txs=0 ERR UPGRADE "v0.44" NEEDED at height: 1827000: INF indexed block height=1826999 module=txindex UPGRADE "v0.44" NEEDED at height: 1827000: ``` This indicates the next steps are ready and you must upgrade the chain. **Change git release branch `v0.5.0`** `git checkout v0.5.0` **Compile and install Konstellation** `make build` **Check konstellation version** `build/knstld version` Should return 0.5.0 **Start Konstellation** `build/knstld start` **Again to run process in background run** `screen -dmSL knstld build/knstld start` #### Block 6179999 At block 6179999 chain will halt, reason same as above. **Change git release branch `v0.6.0`** `git checkout v0.6.0` **Compile and install Konstellation** `make build` **Check konstellation version** `build/knstld version` Should return 0.6.0 **Start Konstellation** `build/knstld start` **Again to run process in background run** `screen -dmSL knstld build/knstld start` #### Block 6564999 At block 6564999 chain will halt, reason same as above. **Change git release branch `v0.6.2`** `git checkout v0.6.2` **Compile and install Konstellation** `make build` **Check konstellation version** `build/knstld version` Should return 0.6.2 **Start Konstellation** `build/knstld start` **Again to run process in background run** `screen -dmSL knstld build/knstld start` #### #### ####
