Pundi X

Full node with Docker

This guide will explain how to install the fxcored mainnet or fxcored testnet command line interface (CLI) on your system with Docker option. With these installed on a server, you can participate on the mainnet or testnet as a Validator.

Install Pundi AIFX

You need to install Pundi AIFX before you go further

Use Docker

  • Pull docker images

if you do not already have docker installed, there will be a prompt for you to install it. Follow the instructions given.

docker pull ghcr.io/PundiAI/fx-core:8.5.1

  • Initializing fxcore

docker run --rm -v $HOME/.fxcore:/root/.fxcore ghcr.io/PundiAI/fx-core:8.5.1 init fx-zakir --chain-id fxcore

  • Download genesis (copy and run each line, line by line)

wget https://raw.githubusercontent.com/PundiAI/fx-core/release/v6.0.x/public/mainnet/genesis.json -O ~/.fxcore/config/genesis.json

Upon startup the node will need to connect to peers. you can add peers to the config.toml config file:

docker run --rm -v $HOME/.fxcore:/root/.fxcore pundiAI/fx-core:8.5.1 config config.toml p2p.seeds "c5877d9d243af1a504caf5b7f7a9c915b3ae94ae@fxcore-mainnet-seed-node-1.functionx.io:26656,b289311ece065c813287e3a25835bb6378999aa5@fxcore-mainnet-seed-node-2.functionx.io:26656,96f04dffc25ffcce11e179581d2a3ab6cb5535d5@fxcore-mainnet-node-1.functionx.io:26656,836ded83bac83a4ac8511826fa1ad4ca2238f960@fxcore-mainnet-node-2.functionx.io:26656,7c7a260eeefda37eac896ae423e78cf345a2ef70@fxcore-mainnet-node-3.functionx.io:26656,0fee38117655b6961319950d6beb929fb194217c@fxcore-mainnet-node-4.functionx.io:26656,6e8818051a2ca9b8be67a6f2ba48c33d8c489d5c@fxcore-mainnet-node-5.functionx.io:26656"

** IMPORTANT At this stage **BEFORE **starting the node, please download the latest snapshot, refer to this link.

And at this stage, what is important is your validator keys that is stored in a json file for you to do a recovery in the future. For more information how to access the files.

  • Run docker

docker run --name fxcore -d --restart=always -p 0.0.0.0:26656:26656 -p 127.0.0.1:26657:26657 -p 127.0.0.1:1317:1317 -p 127.0.0.1:26660:26660 -p 127.0.0.1:8545:8545 -p 127.0.0.1:8546:8546 -v $HOME/.fxcore:/root/.fxcore ghcr.io/PundiAI/fx-core:8.5.1 start

To check if fxcore is synced:

curl localhost:26657/status

Return:

To ensure that the blocks are synced up with your node, under "sync_info", "catching_up value" should be false "catching_up value": false. This may take a few hours and your node has to be fully synced up before proceeding to the next step. You may cross reference the latest block you are synced to "sync_info": "latest_block_height" and the latest block height of our Testnet blockchain on our Testnet blockchain explorer or our Mainnet.

Make sure that every node has a unique priv_validator.json. Do not copy the priv_validator.json from an old node to multiple new nodes. Running two nodes with the same priv_validator.json will cause you to double sign.
